Unbelievable footage from NOAA’s Hurricane Hunters inside the eye of Hurricane Erin.
Simply incredible.

Rapid attribution studies are often incomplete. Study doesn't account for the broadening of the dry season into mid-winter, which leads to increasing likeliness of overlap with offshore wind season (and the probably of encountering the dry hot 100 mph Santa Ana winds that played such a key role).
New UCLA rapid attribution study: “Climate change may be linked to roughly a quarter of the extreme fuel moisture deficit when the fires began.
The fires would still have been extreme without climate change, but probably somewhat smaller and less intense.”

Looks like a nice setup across New Mexico today. Later this afternoon, I expect a couple of supercells across south-central and southeastern New Mexico and a modest tornado chance. I am not able to get out there myself today so here are my thoughts on the forecast: (thread!)

Thanks to a cut-off upper level low sitting over the four corner states, we have quite the light show over New Mexico today. Our Earth Networks Total Lightning Network (ENTLN) picking up a handful of strikes.

Impressive visualization of power outages caused by Hurricane Helene, and the amazing restoration work by linemen.

That is one beefy high pressure system over the East this mid-October. Any tropical activity that wants to form in the Caribbean would steer clear of mainland U.S. and take a westward track. Enjoy the beautiful fall days ahead. 🍂

Comparing accumulated cyclone energy (ACE) during the typical peak 30-day period, to the total ACE excluding that period, for every Atlantic hurricane season on record.
2024, a clear outlier, had one of the quietest peak seasons ever, while still managing the 4th highest "off-peak" ACE on record.

Posted by NWS Sioux Falls...this is a terribly dry map.
Huge precipitation deficits since September 1. No surprise that drought is expanding and worsening.
