More than 1 BILLION birds were estimated to be in flight across the United States on Friday night! It's the highest estimated number of migrating birds in flight at one time so far this year. 🐦

𝟭/ Since 2017, 11 landfalling US hurricanes have each knocked out power to more than 1M customers at once. That’s more than one per season. And 1M customers isn’t 1M people. Each customer averages about 2 people, so that’s roughly 2M people in the dark. 🧵

6.5 hours of #Champi's violent pinhole eyewall on visible imagery. Notice not only the continued core contraction, but also the particularly pronounced standing gravity wave in the southern CDO at close to peak intensity -- fascinating stuff

One of the best hurricane/typhoon datasets we may ever get. From its sharp turn to the northwest to the abundance of mesovortices and Vortex Rossby waves, along with an incredible 3D radar presentation, Super Typhoon #Champi will provide an incredible dataset for in-depth studies of powerful typhoons/hurricanes/cyclones going forward.

This one hurts. A dear friend in life and an excellent colleague in our weather industry Jared Smith (@chswx Charleston Weather) unexpectedly passed away yesterday due to extended complications from his heart surgery last Thursday. It was a planned surgery that was to help avoid further complications and get him where he needed to be, but it turned for the worst and many of us are surprisingly upset and very sad. Just contacted him last Wed night before the surgery and he was very positive and optimistic going into it - even said he wanted to have another get-together after the whole thing was over. Made sure to give him some positive words and wish him well. Glad I did - because I didn't know it would be the last conversation I would have with him. 😥 Jared was a one-of-a-kind person who was both genuine and generous with his time. If you knew him, he was extremely talented in all areas of his careers. I met and worked with him on the @CarolinaWxGroup for many years and we kept in good touch for all things weather here locally. Jared had just gotten married to his wife Lily Wald and was very happy. There are a lot of sad folks today wondering how and why with the complications, but let's focus on the person he was and celebrate his time with us - he touched a lot of lives with his personality and his incredible ability to share his knowledge. Truly a light that shone brightly - gone too soon. Keep him, his family and loved ones in your thoughts and say a prayer for their well being through this hard time. Take care and hug your peeps today - make those calls you've been meaning to make that time has washed over. It's worth it. Pics below include his wife Lily and at a College of Charleston meteorology event with Dr. Marshall Shepherd, TV Personality, Professor, Author as speaker and Meteorologist Trevor Gibbs, who among the first graduates of the CofC meteorology program. Jared was super stoked to be there as you can see. Great memory!

From summer heat to winter chills! 🥵🥶 Temperatures are set to plunge as much as 50 degrees or more across parts of the Midwest and East this weekend, with gusty winds, storms and even some snowflakes possible. bit.ly/4zCqEmO

Very glad our work on WeatherNext Cyclones (WN-C) at @GoogleDeepMind and @GoogleResearch proved useful for forecasting Hurricane Isaias. We were also pleased to see WN-C’s 1,000 member ensemble being used by meteorologists to help assess the full range of possibilities for Isaias’s track and intensity. Such large ensembles are one of the benefits of ML weather models, which are more efficient than traditional physics models. There was debate among meteorologists whether wind shear and dry air would prevent Isaias from rapidly intensifying. WN-C predicted a more easterly path away from these weakening factors, with a >50% chance of a major hurricane from Oct 6th onwards, which steadily grew in confidence until Isaias eventually did reach Category 3 status three days later on Oct 9th, shortly before landfall. Our paper on the front cover of @Nature last month evaluated WN-C against the leading physics models across more than 200 tropical cyclones globally from 2023-2025. We found that WN-C achieves ~1 day of additional useful lead time for cyclone track and intensity (an advance that typically took a decade to achieve). Getting both track and intensity right proved crucial for predicting the true threat of Isaias, and though this was just N=1 tropical cyclone, it’s great to see our breakthrough helping to protect lives and livelihoods in an operational setting. Read the paper here: nature.com/articles/s41586-0…
Last week, Hurricane Isaias made landfall in the Florida Panhandle. Our thoughts are with everyone affected and with the recovery efforts still underway. Earlier and more accurate forecasting can help protect communities by giving them more time to prepare, and we are grateful that Google’s WeatherNext model was able to assist the @NWSNHC 's expert forecasters. Based on initial evaluations, here's how our model supported the response to #Isaias: - Tracking the Hurricane’s Path: WeatherNext was the most accurate model on the storm’s track. While traditional physics models predicted landfall closer to New Orleans, WeatherNext correctly predicted a path further east. This allowed NHC forecasters to highlight the potential for wind and storm surge impacts in the Florida Panhandle from their very first forecast. - More Time to Prepare: Up to three days before landfall, our model consistently predicted its eventual location in the Florida Panhandle to within 60 km or less, supporting the NHC as they honed in on a track toward the Florida Panhandle and issued hurricane watches and warnings to give officials in Florida, Alabama, and Mississippi more time to prepare. - Early Indications about Intensity: Early on, WeatherNext accurately predicted the intensification to a major hurricane. Alongside the regional hurricane models HWRF and HMON, WeatherNext’s intensity forecasts helped NHC forecasters to predict that the Isaias would approach the coast as a category 2 hurricane from the very first advisory. Giving communities more time and more accurate warnings is critical for protecting lives and livelihoods. While model performance varies from storm to storm, Isaias reflects our broader findings. In our recent @Nature paper co-authored with NHC forecasters, evaluating 200+ global tropical cyclones, we found our model provides ~1 day of additional lead time for both track and intensity. It’s been an honor for the @GoogleDeepMind and @GoogleResearch teams to work alongside NHC forecasters. By combining AI, physics models, satellite data, and the crucial expertise of meteorologists, we're excited to keep pushing the boundaries of forecasting to help protect communities.

Call me Dr. Doomsday - we're doing some research on historic storm events with outage prediction @PowerOutage_us . If a storm like Great New England 1938 storm hit we estimate almost 9 million customer outages. This would be a bad day. NOT A FORECAST. #hurricane #newengland

While Stornoway has observed gust of at least 73 mph and Bealach na ba 108 mph... looks like we may have a new Icelandic low pressure record for October... Previous record 938mb according to Met Office.

Something to note with #Isaias - The Majority of Homes in the Panhandle built post-Andrew (the new FBC) were supposed to be built to withstand 130mph winds (Right Image). This does nothing for the (Older) housing stock that already exists up there. Good news is, the 2026 FBC implements new Wind Borne Debris regions (Left Image), mandating 140-150mph wind resistance in the Pensacola Area.

A powerful extratropical low is now striking the coast of Iceland with an estimated central pressure of 928mb and winds of up to hurricane force. Some of the storm's energy is associated with the remnants of Hurricane Isaias last weekend.

16" of snow (1.76" liquid) has fallen at NWS Great Falls since Saturday PM! This historic storm lands as the #9 all-time 2-day snowfall (15.7") and #17 all-time 3-day snowfall for Great Falls. It also marks our 2nd snowiest start to a snow season on record, trailing 2019 #MTwx

Quick case study w/AI using HRRR operational data on the "sting jet" with Hurricane Isaias. I supplied a hypothesis based upon my old research. Yes -- definitely a "sting jet" but origin not like intense extratropical cyclones -- intense air stream was in lower-levels and only dried / descended at very end of the road. Call it --> "cold-conveyor-belt jet wrapped round the upshear side of a hurricane in extratropical transition, with a sting-jet-like descent at its end." The trough decapitated the storm's PV tower, shearing it apart, then drying its west side, and forcing the descent. The trough did not supply the wind -- that was entirely the hurricane undergoing ET. forecasteagle.com/cases/isai…
