Hurricane Season 2026: CSU Cuts Its Forecast to 9 Storms as El Niño Surges
Colorado State University cut its 2026 Atlantic forecast a second time on July 8 — to just 9 named storms, 4 hurricanes, and 1 major, “well below normal.” A fast-strengthening El Niño has held the Atlantic to a single storm (Arthur) and zero hurricanes, while the East Pacific runs hot. US major-hurricane landfall odds are down to 17% (average: 43%).
July 8, 2026 — CSU cuts its forecast again to 9 storms, calls 2026 “well below normal”
Colorado State University released its July update today and lowered the season a second time: 9 named storms, 4 hurricanes, and just 1 major hurricane — down from its June call of 11/5/2 and its April call of 13/6/2. An average season runs 14 named storms, 7 hurricanes, and 3 major. CSU now puts the odds of a major hurricane striking the US coastline at 17%, down from 24% in June and well under the 43% average from 1880–2020. The driver is a fast-strengthening El Niño: forecasters now give an 81% chance of a very strong event that would rank among the largest since 1950, with the Niño 3.4 index near +1.5°C this week and projected to surge toward +3.6°C by late fall. That shear — plus a thick plume of Saharan dust — has held the Atlantic to a single named storm all season (Arthur) and zero hurricanes, while the same El Niño has lit up the East Pacific with four named storms (Amanda, Boris, Cristina, Douglas), its most active start since 1985. NOAA issues its own updated outlook in early August. The count is quiet, but the history below is blunt about the catch: it only takes one landfall to define a season — the 1992 El Niño year produced just 7 storms, and one was Category 5 Andrew.
July 3, 2026 — Two weeks after Arthur, the Atlantic has gone silent — but the Pacific hasn't
As the season crosses the one-third mark, the Atlantic basin still shows a single named storm — Arthur, which fell apart within a day of its June 18 Texas landfall. Nothing has formed since. The National Hurricane Center's tropical weather outlook has held at 0% development odds across the basin for the past week, with dry, sinking air and hostile upper-level winds dominating the Main Development Region. This is the El Niño signature playing out on schedule — and it's not that the tropics are dead. The East Pacific has already produced at least four named storms (Amanda, Boris, Cristina, and Douglas, which formed July 1), because El Niño warms that basin and shears the Atlantic. It was the remnants of East Pacific Cristina that seeded Arthur in the first place. For context, an average Atlantic season doesn't see its first hurricane until around August 11 (NOAA 1991–2020 climatology), so a quiet early July isn't itself unusual — what's telling is the near-total lack of even weak systems. CSU releases its next update on July 8; watch whether the 11-storm June call holds or drops further. The peak is still six to ten weeks out, and El Niño seasons can still deliver a devastating landfall — Hurricane Katrina struck in late August 2005, and its anniversary window is when Gulf attention peaks every year.
June 19, 2026 — Tropical Storm Arthur makes landfall in Texas: the first Atlantic named storm of 2026
Arthur made landfall near Matagorda Bay, Texas, on June 18 with 40 mph sustained winds — barely tropical storm strength. But the rain was the story: 5–10 inches fell across the upper Texas coast, with isolated totals near 20 inches. Flash flooding swamped cars in southeast Texas and Louisiana. Arthur's formation was unusual — it coalesced from the remnants of East Pacific Tropical Storm Cristina crossing the Yucatán, combined with an African wave and a stalled front. By Wednesday night, Arthur was already post-tropical. The season now sits at 1 named storm through Day 19 — matching the historical El Niño pattern of slow, suppressed starts. The Niño 3.4 index has risen to +1.2°C, well above the El Niño threshold. CPC upgraded to an El Niño Advisory on June 11, with a 63% chance of a very strong event by November–January.
June 1, 2026 — Hurricane season is officially underway. Day 1: zero activity.
The 2026 Atlantic hurricane season opened today with no tropical cyclone formation expected anywhere in the basin — the third consecutive year the season has started without a trackable system. Satellite imagery shows widespread dry air and strong upper-level winds, making the atmosphere too hostile for tropical development. That hostility has a name: El Niño. The Niño 3.4 index surged to +1.2°C in late May, nearly double the El Niño threshold. The shear suppression forecasters predicted is now showing up in real-time satellite data. CSU releases its updated June forecast on June 10 — we'll update this article with the revised numbers. NOAA's next update comes in early August.
May 22, 2026 — NOAA's official forecast is in: below-normal season
NOAA released its official 2026 Atlantic Hurricane Season Outlook on May 21. The numbers: 8–14 named storms, 3–6 hurricanes, 1–3 major hurricanes. NOAA assigns a 55% chance of below-normal activity, 35% near-normal, and just 10% above-normal. El Niño is 98% likely to develop during the season, with Pacific SSTs potentially rising 2°C+ above average — driving the strongest wind shear suppression in years. “Although El Niño's impact in the Atlantic Basin can often suppress hurricane development, there is still uncertainty in how each season will unfold,” said NWS Director Ken Graham. Atlantic ocean temps remain warmer than normal but below the record levels that fueled 2024's brutal season. Meanwhile, the May 13–14 super tornado outbreak (206 tornadoes, 78 deaths) demonstrated that El Niño suppression of hurricanes doesn't mean a calm severe weather season — it just redirects the energy.
Three weeks into the 2026 Atlantic hurricane season, the basin has produced exactly one named storm: Tropical Storm Arthur, a short-lived system that made landfall in Texas on June 18 with 40 mph winds before dissipating overnight. Arthur wasn't even a pure Atlantic storm — it formed from the remnants of East Pacific TS Cristina crossing the Yucatán. The Atlantic itself has been too hostile for anything to develop. NOAA's official forecast calls for 8–14 named storms, well below the 14-storm average. The culprit: an El Niño with Niño 3.4 already at +1.2°C and climbing.
After 2024's brutal season (18 storms, $124 billion in damage, 252+ deaths from Helene alone), a quiet June is welcome. But “below average” doesn't mean safe. The 1992 season had just 7 named storms. One of them was Hurricane Andrew, a Category 5 that destroyed 63,000 homes in South Florida. The 2004 season developed during El Niño conditions and still produced 4 hurricane landfalls in Florida. Arthur proved something similar — even a minimal tropical storm can dump 20 inches of rain and cause flash flooding.
The question is no longer whether El Niño will suppress hurricanes — it already is. CPC issued an El Niño Advisory on June 11 with 63% odds of a very strong event by winter. The real question: if this El Niño hits +3.0°C as ECMWF projects, does hurricane suppression become near-total? Or does one well-positioned storm still slip through? Our analysis of every El Niño hurricane season since 1950 shows the answer isn't as reassuring as the forecast numbers suggest.
Every 2026 Forecast, Compared
Four major forecast groups, four different answers. The most important number isn't named storms — it's major hurricanes (Category 3+), because those cause 85% of all hurricane damage despite making up only about 20% of landfalls.
| Source | Named Storms | Hurricanes | Major (Cat 3+) |
|---|---|---|---|
| CSU (July) | 9 | 4 | 1 |
| TSR | 12 | 5 | 1 |
| AccuWeather | 11–16 | 4–7 | 2–4 |
| NOAA (Official) | 8–14 | 3–6 | 1–3 |
| U of Arizona | 20 | 9 | 4 |
| 30-yr Average | 14 | 7 | 3 |
CSU's numbers above are its July 8, 2026 update (cut from 13/6/2 in April and 11/5/2 in June). TSR revised down from their December preliminary. AccuWeather released March 25. U of Arizona is the lone above-average forecast — a call that looks increasingly unlikely as El Niño strengthens.
Why Forecasters Can't Agree: El Niño vs. Atlantic SSTs
This is the most interesting disagreement in hurricane forecasting in years. Here's the tension in plain terms:
Team “Below Average” (CSU, TSR, NOAA) — confirmed by June 1 data
El Niño is now 98% likely, with Niño 3.4 at +1.2°C and rising. June 1 satellite imagery showed exactly what these models predicted: dry air and hostile upper-level winds across the Atlantic, making tropical development impossible. When El Niño is strong, it creates vertical wind shear that tears apart developing hurricanes. In the two strongest El Niño years (1997-98 and 2015-16), the Atlantic produced just 8 and 11 named storms respectively. A +3.0°C event would produce shear levels with no modern precedent.
Team “Above Average” (U of Arizona)
Atlantic sea surface temperatures are at record levels. The North Atlantic is in a warm phase of its multidecadal oscillation (+AMO), and global SSTs set a new daily record in mid-April 2026. The University of Arizona argues this warmth provides so much fuel that hurricanes will form despite El Niño's shear. They point to 2023-24: a strong El Niño year that still produced 19 named storms because Atlantic temps were so extreme.
NOAA's May 21 forecast settled this — at least for now. Their range of 8–14 storms with 55% below-normal probability confirms El Niño shear is dominating their models. The floor of 8 named storms would be the quietest Atlantic season since 2014. If this El Niño reaches +3.0°C as ECMWF models project, even the U of Arizona's warm-SST argument becomes very hard to sustain. The 1997-98 super El Niño produced just 8 named storms, and this one may be stronger.
What El Niño Hurricane Seasons Actually Look Like
Forecasts are educated guesses. History is data. Here's what happened in every El Niño Atlantic hurricane season since 1991 — the good, the bad, and the ones that defied the “El Niño = quiet season” assumption.
| El Niño Year | Strength | Storms | Hurricanes | Major |
|---|---|---|---|---|
| 2023-24 | Strong | 19 | 7 | 3 |
| 2015-16 | Super | 11 | 4 | 2 |
| 2009-10 | Moderate | 9 | 3 | 2 |
| 2006-07 | Moderate | 10 | 5 | 2 |
| 2004-05 | Weak | 15 | 9 | 6 |
| 2002-03 | Moderate | 12 | 4 | 2 |
| 1997-98 | Super | 8 | 3 | 1 |
| 1991-92 | Moderate | 7 | 4 | 1 |
The Uncomfortable Pattern
The average El Niño season since 1991 produced roughly 11 named storms — 21% fewer than normal. But look at the outliers: 2004 produced 15 storms including 6 major hurricanes and 4 Florida landfalls during a weak El Niño. And 2023-24 hit 19 storms during a strong El Niño because Atlantic SSTs were extreme. The lesson: El Niño reduces the average but doesn't set the ceiling. One well-placed Category 4 makes a “below average” season devastating.
Hurricane Risk by State: 170+ Years of NOAA Data
Seasonal forecasts tell you how many storms form. They don't tell you where they hit. For that, we have to look at history. NOAA's HURDAT2 database tracks every hurricane landfall since 1851. Three states absorb over 80% of all US hurricane landfalls.
120 hurricanes since 1851 · 37 major (Cat 3+)
Costliest: Hurricane Andrew (1992)
64 hurricanes since 1851 · 19 major (Cat 3+)
Costliest: Hurricane Harvey (2017)
62 hurricanes since 1851 · 18 major (Cat 3+)
Costliest: Hurricane Katrina (2005)
55 hurricanes since 1851 · 7 major (Cat 3+)
Costliest: Hurricane Helene (2024)
30 hurricanes since 1851 · 5 major (Cat 3+)
Costliest: Hurricane Hugo (1989)

2026 US Landfall Probabilities
CSU calculates landfall probability separately from storm counts. The entire-US figure below is CSU's July 8 number (cut from 24% in June); the regional splits are its latest published breakdown. All reflect the combined effect of El Niño suppression and expected storm tracks.
Every region is below its long-term average. The Gulf Coast at 14% vs. 27% average is a meaningful reduction. But “below average” is not “zero”: even a 17% chance of a major hurricane striking the US coast is better than 1-in-6 odds — and 1992 proved a 7-storm season can still produce a Category 5.
Month-by-Month: When Hurricanes Actually Form
Not all hurricane season months are equal. Here's when the real risk starts, based on 170+ years of NOAA records.
For 2026, El Niño is strengthening through the summer with Niño 3.4 at +1.2°C and climbing. If it follows the development curve models project, August and September — the peak months — will see the maximum suppressive effect. Arthur's brief appearance in June confirms this — the storm couldn't even sustain itself for 24 hours in the hostile environment. The shear should be strongest exactly when it matters most.
How Much Should You Trust April Forecasts?
Honestly? Use them as a general direction, not a precise prediction. CSU's April forecasts correctly identify above-average vs. below-average seasons about 60-70% of the time. But exact storm counts are a different story.
In 2024, CSU's April forecast called for 23 named storms. The actual number was 18 — a miss of 5 storms, but the “above average” call was correct. In 2015, forecasters predicted near-normal activity and got it right thanks to strong El Niño suppression. The forecast CSU issues in June has historically been more accurate because by then, SST patterns are clearer and El Niño strength is more certain.
🔄 June 12 Update: CSU Cuts Forecast — 11 Named Storms, Down from 13
CSU released their revised June 10 forecast and dropped their numbers significantly. The updated call: 11 named storms (was 13), 5 hurricanes (was 6), 2 major hurricanes (unchanged). Landfall probability for the entire US coastline dropped to 24% (was 32%), well below the 43% historical average. East Coast probability fell to 11% (avg: 21%), Gulf Coast to 14% (avg: 27%).
The reason: El Niño is now the “dominant factor” per CSU. CPC issued an El Niño Advisory on June 11, confirming the transition with 63% odds of a very strong event by November–January. The hostile wind shear visible since June 1 persists. Through June 19, the East Pacific produced 3 tropical storms (Amanda, Boris, Cristina) while the Atlantic had just 1 — Tropical Storm Arthur, which formed on June 17 from Cristina's remnants crossing the Yucatán and made landfall in Texas on June 18.
What this means: 11 named storms would be the quietest Atlantic season since 2014, when strong El Niño produced just 8. The U of Arizona outlier call of 20 storms looks increasingly unlikely. NOAA's next update comes in early August ahead of the September peak.
Update — July 8: CSU cut the forecast a second time, to 9 named storms, 4 hurricanes, and 1 major, and lowered the US major-hurricane landfall odds to 17% (from 24%). With a very strong El Niño now 81% likely, 2026 is tracking toward one of the quietest Atlantic seasons of the past decade.
Same El Niño, Different Story: Fewer Hurricanes but a Hotter Summer
The same El Niño that's suppressing hurricane activity is amplifying summer heat across most of the country. NOAA's CPC has 36 states leaning above-normal temperatures. Drought covers 61% of the lower 48. It's the classic El Niño tradeoff: fewer hurricanes, but more heat, more drought, and higher wildfire risk.
