A look at #Covid_19 cases by county in the United States. Data collected from both state health departments and local news outlets. As always, keep tabs on local health information for the most relevant information for your situation. #coronavirus #CoronaVirusUpdate #COVID19

NWS has confirmed over 100 tornadoes from the #tornado outbreak this past Sunday and Monday. Big thanks to @Cyclonebiskit and Cody Fields for gathering the data for this map! (shoutout to NWS Storm Prediction Center for nailing the forecast) #MSwx #ALwx #GAwx #LAwx #SCwx #NCwx #TNwx #TXwx

How have the paths of Atlantic #hurricanes changed each decade? A look at the distribution of accumulated cyclone energy shows each decade's hotspots, including the active Caribbean + Gulf of the 2000s and the Bahamas of the last decade. #hurricaneseason #Weather #tropical #wx

The eye of #HurricaneEta has been clearing out and warming considerably in the last hr, with numerous lightning strikes in the eyewall. This is often a sign of further intensification in an already intense storm. A plane is en route to probe the storm. #wxtwitter #Eta #hurricane

Today is the last day of the official 2020 Atlantic hurricane season ... but storms can still form in December! Here's a family portrait of the record-breaking 31 storms so far this year. It took many hours to draw all the storms! #HurricaneSeason #weather #Tropical #hurricane

10:07 AM measurement indicating a snow depth of 5.3 inches on a driveway, about 20 ft away from the SW facing side of a home. 3.5 mi WSW Sunset Valley, TX NWS Austin/San Antonio TravisCountySevereWx #ewxspotter #atxwx #austinsnow

Here's a look at the maximum rainfall received in each county in the continental US from a tropical or subtropical cyclone between 1900-2020. Harvey and Florence leave noticeable marks. Big thanks to DRmetwatch for assisting w/ data collection! #hurricane #tropical #wxtwitter

Radar clearly shows the structure of the mesocyclone and part of the strong tornado that recently moved through Mayfield Kentucky. Hopefully everyone in storm's path was able to seek shelter and keep themselves and their family safe.

Comparison of the 1925 Tri-State tornado and the storm that produced at least one tornado striking communities including Monette, AR, and Mayfield, KY. Regardless of whether or not it was a single tornado, the longevity of this storm will likely be studied for decades to come.

Careful precipitation trend analysis from ship based observations done by my UW Atmos/Ocean Sci colleague Grant Petty and student Harrison Tran reveals patterns to "Seventy-Year Trends in Ship-Reported Oceanic Precipitation Frequency" agupubs.onlinelibrary.wiley.com/doi/10.1029/20…

The environment for #HurricaneHilary has been exceptionally conducive to rapid intensification. The SHIPS rapid intensification index (which estimates the probability of rapid intensification) for #Hilary has set or nearly set all-time records over the past day. #California

Radar from Cancun shows Tropical Storm #Idalia organizing under the hood, with the radar-observed rotation nestled well within a large burst of convection observed on satellite H/t Brian McNoldy / Conagua for the radar imagery, Dr. Levi Cowan for satellite #HurricaneSeason

The GOES-18 satellite over the eastern Pacific captured this unique and dramatic perspective of both Major Hurricane #Franklin and Tropical Storm #Idalia in the Caribbean and open Atlantic this morning. #HurricaneSeason #HurricaneFranklin #TropicalStormIdalia #HurricaneIdalia

The National Hurricane Center released their TCR on Hurricane #Otis. The day before Otis rapidly intensified, capped convection might've allowed Otis to build stout low-lvl vortex. W mid-lvl winds + evap cooling aloft + high SSTs later destabilized mid-lvls, enabling rapid convective growth

High-res satellite imagery can help identify #tornado paths in rural or remote areas. When vegetation is present, before- and after-images can highlight paths, as shown here with the May 22 EF3 tornado in West Texas, WNW of San Angelo. There were fortunately no injuries here.

With #HurricaneSeason underway, here's an updated chart / schedule for when computer models become available on Dr. Levi Cowan. An active Atlantic hurricane season is anticipated this year. As always, stay #WeatherReady, and follow your local weather service for key updates.

Hurricane #Beryl is now in view of Barbados radar. Winds + surge + rain are forecast to begin affecting Windward Islands tonight. Beryl is an unusually powerful storm for this time of year and area. Radar from Brian McNoldy and BarbadosMetServices. Satellite imagery from Dr. Levi Cowan.

Tropical Storm #Helene has been strengthening throughout the day. The increase in rain detected by the CONAGUA Clima radar in Cancun closer to the storm's center suggest further intensification may continue into tonight. Satellite from Dr. Levi Cowan #HurricaneSeason

Tropical Storm Milton is forecast to approach Florida mid week. On top of the later threat of surge and hurricane winds, flash flooding across FL is possible starting tonight. Follow National Hurricane Center for updates and get local weather information from weather.gov. #FLwx
