Find out why in my 2025 Atlantic hurricane season-in-review, out now. Pour yourself a tall glass of nutritious, delicious beef tallow and let’s take a look back on the dizzying highs and soporific lulls of a bizarre season that defied logic, convention, and, often, convection.

As I laid out yesterday, this is a cataclysmic wind, surge, and flood event for Jamaica. I will have an update this afternoon on how landfall played out, but for now, please keep Jamaica in your thoughts and prayers. They need them.

Very cool long water vapor loop of #Humberto and #Imelda between September 28th and October 1st from College of DuPage, btw.

Thanks for reading and here's hoping that the luck of the 1st half of hurricane season can last through the 2nd half. After a record 10 major hurricanes in 9 yrs we need a break on the Gulf Coast.

Check out my full analysis of late-season landfall risks here:

So, the war between favorable ocean & hostile atmospheric conditions may persist in the final third of hurricane season and U.S. landfall risks.

WeatherTiger's model of post-9/20 Gulf/W. Carib tropical activity is a bit above normal but not nearly as busy as 2020/24 late seasons.

The 2nd key predictor of post-9/20 Gulf/W. Carib activity is September ridging over the SE United States. More Sept. ridging is correlated with more hurricane activity.

Sept. 2025 has been the exact opposite of this pattern so far: persistent deep troughing over the eastern U.S.

Only Gulf & W. Caribbean (west of 75W) activity post-9/20 translates to more late season U.S. landfalls.

SSTs are 1 key predictor of late season Gulf/Carib storms. More activity is linked to warm Caribbean/C. Atlantic, colder Pacific/Nina conditions. Sept. 2025 resembles that.

Conditions in the east Atlantic may become more conducive for waves to develop in the next week.

But that may not translate to U.S. landfall risks. After 9/20, more hurricane activity east of the Lesser Antilles is actually linked to slightly fewer late-season U.S. landfalls.
