Will any Category 4 hurricane make landfall in the US in before 2027?

- [2026-09-27] The NHC's Atlantic Tropical Weather Outlook shows only one active system, Tropical Depression Fay, located well to the west-southwest of the Azores, far from the US coast, plus a low-chance disturbance near Bermuda; no Atlantic system threatens US landfall. (https://www.nhc.noaa.gov/gtwo.php) - [2026-09-22] According to NOAA data, as of Sept. 22, the official count stands at six named storms, zero hurricanes and zero major hurricanes in the 2026 Atlantic season, the latest a hurricane has formed since 1914. (https://parade.com/news/atlantic-hurricane-season-breaks-112-year-record-noaa-data-shows-not-a-single-hurricane-has-formed-in-2026) - [2026-09-24] A separate outlet confirms through Sept. 24, the Atlantic basin has produced six named storms, but not one has strengthened into a hurricane . (https://cbs12.com/weather/hurricane-stories/no-atlantic-hurricanes-yet-in-2026-a-rarity-not-seen-in-more-than-a-century-1907-1914-2026-el-nino-atlantic-basin-lull-climatological-peak-hurricane-season) - [2026-09] Wikipedia's tracker confirms the 2026 Atlantic season stats: Total storms: 6, Hurricanes: 0, Major hurricanes (Cat. 3+): 0 , as of the most recent update. (https://en.wikipedia.org/wiki/2026_Atlantic_hurricane_season) - [2026-09] The only three Atlantic systems to hit the US mainland in 2026 were weak tropical storms: Tropical Storm Arthur formed on June 17 and impacted much of the northwestern coast of the Gulf of Mexico; Tropical Storm Bertha formed a little over a month later, impacting nearly the entire United States's Gulf Coast; and in September, Tropical Storm Edouard made landfall close to the Texas–Louisiana border — none reached even hurricane strength. - [2026-08-06] NOAA's mid-season outlook update reduced its forecast, citing El Niño suppression, to 7-13 named storms, of which 2-6 could become hurricanes, including 0-2 major hurricanes for the entire June–November season. - [2026-09-21] Historical framing: this is the Atlantic basin officially reaching late September having produced only six named storms and zero hurricanes , the first time since 1914 this has happened, per a broadcast report. (https://www.wcax.com/2026/09/21/first-atlantic-hurricane-season-without-hurricane-by-sept-21-112-years/) - [2026-09-22] CBC reporting corroborates: so far, there have been no hurricanes in the 2026 Atlantic hurricane season; as of this writing, there have been only six named storms this Atlantic hurricane season, and most of them only lasted a couple of days . (https://www.cbc.ca/news/science/quiet-2026-atlantic-hurricane-season-9.7352480) - [2026-09-26] Meanwhile, the active hurricane in the news is Pacific Hurricane Polo, which moved away from Mexico's Pacific coast on Saturday as a downgraded Category 4, before an expected return to make landfall in Baja California Sur on Monday — this is a Mexican, not US, landfall and in the Eastern Pacific basin, so it is irrelevant to this Atlantic/conterminous-US market. (https://www.usnews.com/news/world/articles/2026-09-26/category-5-hurricane-polo-threatens-mexicos-coast-landfall-expected-monday) - [2025-season] For context on base rates, the prior (2025) Atlantic season also produced no US hurricane landfalls: no hurricanes made landfall in the United States this season, for the first time since 2015 . (https://en.wikipedia.org/wiki/2025_Atlantic_hurricane_season) - [2026-09-27] NHC's Central Pacific/Eastern Pacific outlook shows the only major hurricane activity (Polo, Odalys, Nolo) confined to the Eastern/Central Pacific near Mexico and Hawaii, not the Atlantic basin or conterminous US coastline. (https://www.nhc.noaa.gov/gtwo.php) BOTTOM LINE: With roughly two months left in the 2026 Atlantic hurricane season (through Nov 30) and the season having produced zero hurricanes of any category through late September (a 112-year record for lateness), the base case for a Category 4 US landfall before the Dec 31, 2026 deadline is currently very unfavorable; only a rapid, unprecedented late-season shift with a US-landfalling major hurricane could flip this to "Yes." NOT FOUND: No official NHC/NOAA statement was found addressing the specific market question directly; no evidence of any Category 3+ Atlantic hurricane forming or threatening the US coast as of Sept 27-28, 2026; could not access the live NOAA press release page directly (fetched via cached search snippet instead).

- [2017-09-10] Historically, Category 4+ Atlantic hurricane landfalls in the continental US are rare: Category 4 or stronger Atlantic hurricane landfalls in the U.S. are a rare occurrence with only 27 documented since 1851, including Harvey and Irma. Roughly 80% of these strikes concentrate in Florida, Texas, and Louisiana. https://weather.com/storms/hurricane/news/hurricane-irma-harvey-landfall-category-4-united-states-history - [2022-09-29] Zooming into the modern era, Hurricane Ian made landfall in Florida as the ninth storm of Category 4 or 5 to hit the U.S. since 1972 , i.e. roughly one every 5-6 years on average, though compared to three major continental U.S. hurricane landfalls out of a total 13 in the 2010s, there have already been four in the last two years alone as of that writing — indicating clustering/acceleration rather than a flat rate. https://time.com/6218275/strongest-hurricanes-us-map/ - [2022-09-29] A once-common talking point (now dated) noted that in the past five years, at least one Category 4 or 5 hurricane has made landfall in the U.S. each year , reflecting an unusually active 2017-2022 stretch (Harvey, Irma, Michael, Laura, Ida, Ian) rather than a permanent trend. https://time.com/6218275/strongest-hurricanes-us-map/ - [2024-09] More recently, Hurricane Helene (2024) hit the Florida Big Bend at Category 4 strength, continuing near-annual major/Cat4 US landfalls in 2017-2024, per Wikipedia's season summary: Hurricane Helene developed over the western Caribbean and later made landfall in the Big Bend region of Florida at Category 4 strength . https://en.wikipedia.org/wiki/2024_Atlantic_hurricane_season - [2025] By contrast, the 2025 Atlantic season produced no Cat4+ US landfall: strong storms like Gabrielle and Humberto reached Category 4/5 but stayed offshore — Humberto attained Category 5 strength, but did not make landfall — showing that even active seasons can miss the US mainland at that intensity. - [2026-05-21] NOAA's official base-rate comparison: An average season has 14 named storms with seven hurricanes, including three major hurricanes. NOAA's initial 2026 outlook set expectations well below that average. https://www.noaa.gov/news-release/noaa-predicts-below-normal-2026-atlantic-hurricane-season - [2026-05-21] Initial 2026 NOAA outlook: NOAA's outlook for the 2026 Atlantic hurricane season, which runs June 1 to November 30, predicts a 35% chance of a near-normal season, a 10% chance of an above-normal season, and a 55% chance of a below-normal season, with a total of 8-14 named storms, 3-6 hurricanes, including 1-3 major hurricanes. https://www.noaa.gov/news-release/noaa-predicts-below-normal-2026-atlantic-hurricane-season - [2026-08-06] NOAA's mid-season update sharply cut expectations further amid a very strong El Niño: the agency now predicts between seven and 13 storms, with two to six of those becoming hurricanes, and zero to two of those hurricanes are expected to become major... NOAA predicts a 75% chance of below-normal hurricane season activity, which is well above the agency's initial prediction of a 55% chance . https://www.11alive.com/article/weather/hurricane/noaa-2026-atlantic-hurricane-season-forecast-update-below-average-start/507-4c6809e8-2f44-4c36-aa87-203132832cd9 - [2026-07] Colorado State University went further, explicitly downgrading landfall risk: CSU further reduced its prediction to nine named storms, four hurricanes, and one major hurricane... resulting in very strong vertical wind shear across the Atlantic Basin. Additionally, the university forecast well below-average chances for a direct hurricane strike on the Continental United States and the Caribbean. https://en.wikipedia.org/wiki/2026_Atlantic_hurricane_season - [2026-09-10] As of the season's climatological peak, activity remains historically suppressed: there were no active tropical storms or hurricanes anywhere in the Atlantic Basin during this second week of September; the National Hurricane Center hadn't even circled any areas that could develop in the next seven days , and none of the season's storms had become a hurricane; the current ACE index would be typical of a hurricane season in the second week of July, rather than the peak second week of September. https://weather.com/2026/09/10/storms/hurricane/atlantic-hurricane-season-quiet-during-peak-september - [2026-09-28] Per Wikipedia's live season tracker, the 2026 Atlantic season to date has produced zero hurricanes and zero major hurricanes: seasonal statistics show "Hurricanes: 0" and "Major hurricanes (Cat. 3+): 0" with the strongest storm (Bertha) peaking at only 60 mph, well below hurricane strength. https://en.wikipedia.org/wiki/2026_Atlantic_hurricane_season - [2026-09] The satellite-era record for latest first Atlantic hurricane was broken this season: On September 11, the 2026 season surpassed the latest date for the first Atlantic hurricane of a season in the satellite era. As of September 2026, the season has been extremely inactive. Seasonal forecasts widely anticipated a below-normal season due to a very strong El Niño event in the Pacific. https://en.wikipedia.org/wiki/2026_Atlantic_hurricane_season BOTTOM LINE: The unconditional base rate for a Category 4+ US landfall in a given Atlantic season is modest (roughly 1-in-5 to 1-in-3 seasons historically, higher in the 2017-2024 cluster), but 2026 is an unusually poor year for this outcome — every official seasonal forecast (NOAA, CSU) has repeatedly been downgraded due to a strong El Niño, and as of the climatological peak (mid-September) the Atlantic has not produced a single hurricane, let alone a major one, making the historical base rate a considerable overestimate for the remainder of this specific season. NOT FOUND: No official Colorado State University or NOAA numeric probability specifically for "Cat4 US landfall" (only general "major hurricane" and "direct strike" qualitative language); no comprehensive statistical study giving a precise historical per-season frequency of Category 4-specifically (as opposed to Category 4-or-5) US landfalls.

YES means: at least one hurricane makes landfall on the conterminous US coastline at Category 4 intensity (130–156 mph sustained winds) per NHC advisories, at any point between market creation (2025-12-29) and December 31, 2026, 11:59 PM ET — i.e., effectively during the remainder of the 2026 Atlantic season (through Nov 30) or, in a limiting case, in early 2026 before the season proper (historically near-impossible). - [2026-09-27] The season is not over: NHC's own operational discussion notes there are currently no active TCs, and the National Hurricane Center is monitoring an area in the subtropical Atlantic with a 30% chance of TC formation in the next week , and separately a new Bermuda-area disturbance was given a chance to spawn a new named storm this week even as Tropical Depression Fay continues weakening , per a fresh Sept 27 tropical update. - [2026-09-27] The same report flags the recurring seasonal wildcard: this time of year, a feature over Central America called the Central American Gyre creates an area of broad low pressure that can spawn development anywhere from the far eastern Pacific, the Caribbean, or the Gulf, and is responsible for most tropical systems in June and many in late September and early October — a known mechanism for abrupt, short-fuse Gulf/Caribbean intensification close to the US coast. - [2026-09] CSU's mid-September update, while still favoring a quiet fortnight, explicitly notes a shift in the intraseasonal signal: the MJO is forecast to be relatively weak but favoring enhanced convection across the Western Hemisphere in week one, potentially propagating across Africa in week two... when the MJO is enhancing convection over Africa, Atlantic TC activity is typically elevated , meaning the suppression is not expected to be permanent for the rest of the season. - [2026-09] AccuWeather's seasonal meteorologists likewise conceded persistent Gulf/Caribbean thermal fuel: water temperatures in parts of the western Caribbean and the Gulf are near 90°F, well above the 80°F threshold for tropical development , sufficient in principle to support rapid intensification to major-hurricane strength if shear relaxes even briefly. - [2026-08-06] NOAA's own official cut-down forecast still leaves room for the qualifying event: even the most bearish official range keeps the total number of named storms and major hurricanes expected by one storm each above zero, and NOAA's later update explicitly retains a 75% chance for below-normal activity, with a 20% chance of a near-normal season, and just a 5% chance of above-normal activity — meaning a 25% chance of near-/above-normal activity remains live, not zero. - [2025-10] Climatology shows the "empty season, then a late monster" pattern is not unprecedented and happened just last year: the 2025 season had TC activity cease throughout much of the peak season, similar to the lull observed in 2024... [before] two late-season clusters of activity brought cumulative season activity to above-average levels , culminating in Hurricane Melissa becoming the third Category 5 hurricane of the season and the joint-strongest landfalling Atlantic hurricane, with 185 mph winds at landfall, in late October (Jamaica, not US, but proof that quiet Septembers can flip violently in October). - [2024-10] The direct historical playbook for a "quiet-then-Cat4-landfall" season exists in 2024: Hurricane Milton became the most intense hurricane of the 2024 season with sustained winds around 180 mph on Oct. 7, and made landfall near Siesta Key, Fla., as a major Category 3 hurricane on Oct. 9 — showing October Gulf systems can undergo extreme rapid intensification just before US landfall (Milton was Cat 5 at peak, weakening only slightly before striking Florida). - [general] Seasonal climatology confirms October/November are not dead zones for the US: on average, October and November yield about four named storms, with two of those typically reaching hurricane strength and one intensifying into a major hurricane , and while most such storms recurve away from the coast, Florida can remain vulnerable into November, because of tropical systems that develop in the western Caribbean or south . - [general] Florida-specific October risk is non-trivial in the historical record: 11 major hurricanes (Category 3 or higher) hit Florida in October between 1851 and 2019, with six in just the past four years starting with Matthew, followed by Irma and Maria in 2017, Michael in 2018, and Dorian and Lorenzo — several of which (Michael 2018) made landfall at Category 4/5 strength, underscoring that a single westerly Caribbean system reaching the Gulf can still produce a qualifying strike even after a historically quiet peak season. - [2026-09-27] Gulf-adjacent moisture is already flowing from an unrelated basin: the tropics can be fairly active in late September and early October... the quiet Atlantic basin might spawn a new named storm this week , and the same forecaster piece notes models are likely to depict developed storms in the Gulf in the coming weeks, though there is no confidence they will form as the environment remains hostile — i.e., model signals for Gulf development exist even if unconfirmed, keeping the pathway open going into October. BOTTOM LINE: The single most likely path to YES is a rapid-intensification Gulf-of-Mexico or western-Caribbean system forming off the Central American Gyre or a relaxed-shear MDR wave sometime in October–November, mirroring the Milton (2024) and Melissa (2025) precedents of extreme late-season intensification; the season remains open for roughly two more months, El Niño shear has been intermittently interrupted by favorable MJO phases, and Gulf/Caribbean SSTs remain fully sufficient to fuel a Category 4 landfall despite the historically quiet start. NOT FOUND: No current (as of Sept 27-28) NHC invest area has been assigned higher than a 40% seven-day formation chance, and no model consensus points to any specific system reaching Category 4 intensity near the US coast in the next 1-2 weeks; no official NOAA/CSU numeric probability specifically for "Category 4 US landfall by Dec 31" was located.

YES means: a hurricane makes landfall on the conterminous US coastline at Category 4 strength (130-156 mph sustained winds) at some point between market creation (2025-12-29) and December 31, 2026, 11:59 PM ET, as reported in an initial NHC advisory. This dimension argues for NO. - [2026-09-27] NHC's latest Atlantic Graphical Tropical Weather Outlook shows only Tropical Depression Fay (weak, far east-southwest of the Azores) and a 10%-chance disturbance southeast of Bermuda — no system anywhere near the US coast and nothing with meaningful development odds. (https://www.nhc.noaa.gov/gtwo.php) - [2026-09-21] A FOX Weather analysis citing NOAA data reports El Niño conditions have a 97% chance of a Super El Niño this fall and winter that will last through early spring , which historically drives strong Atlantic wind shear straight through the remainder of the 2026 season. - [2026-09-21] Critically, FOX Weather's own historical dataset found that " Homegrown " Gulf/Caribbean tropical systems (the Central American Gyre mechanism that spawned Cat4 storms like Idalia) have "not formed during Super El Niño years since 1960" in October — the exact month when El Niño is forecast to peak, cutting off the leading historical source of late-season US-threatening storms this year. - [2026-08-21] Moody's/RMS analysis notes NOAA's finding that " every North Atlantic hurricane season that has coincided with a strong El Niño since 1950 has produced below-normal seasonal activity ," reinforcing that the suppressive mechanism is not a short-term anomaly but a robust seasonal pattern expected to persist into Q4. - [2026-08-21] The same analysis shows accumulated cyclone energy (ACE) — the standard measure of storm intensity/duration — " running 84 percent below the 1991–2020 average " as of August 21, indicating a severe energy deficit that October/November activity would need to overcome from a very low base. - [2026-09] AccuWeather reports the 2026 El Niño's forecast mean of 2.66 " would rank as the strongest in the historical record if it verifies... exceed the previous highest three-month mean of 2.40 from November 1982 through February 1983 ," meaning conditions are trending toward an unprecedented suppressive regime, not merely a normal El Niño year. - [2026-09-25] U.S. News confirms NOAA's official numeric range for the whole season remains capped at " three to six hurricanes, including one to three major storms... That compares to seven hurricanes in an average season, including three that turn out to be major ," meaning even NOAA's own outlook implies a meaningfully-below-average chance of any major hurricane (Cat 3+) forming at all, let alone one specifically reaching Cat 4 strength and making a precise US landfall. - [2026-09] Historical precedent for extremely slow starts is unfavorable to a rebound: in the closest analog, the 1914 season (the last year with zero hurricanes this late), Wikipedia's records show the entire season produced just " Total storms: 1 (record low) - Hurricanes: 0 (record low, tied with 1907) " — i.e., 1914 never recovered to produce any hurricane, let alone a major or Cat4 one, the whole season. - [2026-09-24 to 09-28] No Gulf, Caribbean, or western Atlantic invest, tropical wave, or disturbance is currently flagged by NHC with meaningful (>10%) development odds, and none of the three 2026 US-landfalling systems to date (Arthur, Bertha, Edouard) exceeded tropical-storm strength, underscoring that the steering/thermodynamic environment has not favored intensification near the US coast all season. - [2026-09-26] The only Category 4 hurricane in the news (Polo) is confined to the Eastern Pacific and threatens Mexico's Baja California Sur, not the conterminous US Atlantic/Gulf coast, and is irrelevant to this market's resolution criteria which is silent on Pacific storms but implicitly Atlantic-basin/Gulf-facing given "conterminous United States" landfall. - [2025] The most recent full season (2025) also produced zero Category 4+ US landfalls despite offshore majors (Humberto reached Cat 5 without landfall), reinforcing that even active Atlantic seasons can fail this specific bar, and 2026 is considerably less active than 2025 was. BOTTOM LINE: With roughly 63 days remaining in the 2026 Atlantic season (through Nov 30) plus a one-month tail to Dec 31, zero hurricanes of any category have formed through a record-breaking date, a historically unprecedented Super El Niño is intensifying into the peak window, and the specific "homegrown" Gulf-development mechanism responsible for past Cat4 US landfalls (e.g., Idalia) has never produced an October storm in any Super El Niño year since 1960 — collectively making the case for NO unusually strong, absent a sudden and historically rare late-season reversal. NOT FOUND: No official NHC or CSU statement explicitly ruling out Cat4 US landfall for the remainder of 2026; no confirmed tropical disturbance currently tracked toward the US coast as of Sept 27-28, 2026; no numeric probability from NOAA/CSU specifically isolating "Category 4 (not 5)" US landfall risk.
