Not a very promising view (GOES-18), considering it's still morning in the West! Forward scattering does accentuate the smoke. From a different perspective (GOES-19), it doesn't look as bad. My heart goes out to all the families in the Spokane area that lost their homes yesterday.

This is appalling and un-American. This hearkens back to what the country experienced before the Civil War, when local post offices were heavily politicized and mail of disfavored viewpoints was suppressed. Lots of corruption & malfeasance. www.nytimes.com/2026/07/24/b... time.com/7244554/dang...

Parts of Ontario and northern Michigan are experiencing a truly awful combination of extreme heat and terrible air quality due to the ongoing heatwave and wildfires in the region. While satellite imagery looks dramatic, what matters for population exposure is smoke at the surface. 1/

#Rota (CNMI) can be seen in the southern eye of Supertyphoon #Bevi. The storm, which has estimated maximum 1-minute sustained winds of 180 mph, is directly impacting the small island of ~1900 people. This is the 2nd significant typhoon impact in less than 4 months for CNMI, a U.S. territory.

Typhoon Bavi (WP09) looks set to continue its rapid intensification it travels toward the Commonwealth of the Northern Marianas (CNMI). Currently predicted to be a 140-kt supertyphoon by the time it arrives, but some experimental ensemble members show potential for it to be even more intense. 1/

Today's prescribed burn in Arizona put up a very robust smoke plume! The burn was planned for 11,000 acres. Based on the satellite imagery from CSU CIRA (@cira-csu.bsky.social), I'm guessing they succeeded . . . #UpperBeaverCreekPrescribedBurn #AZfire slider.cira.colostate.edu?sat=goes-19&...

One factor that supported Melissa reaching this record: an Argo float southeast of Jamaica shows a dramatic decrease in upper-level ocean temperature before (18 Oct) and after (28 Oct) the storm. My heart goes out to the folks in Jamaica facing this powerful hurricane's numerous hazards today. 💔
Plot of vertical temperature profiles measured by one Argo float from October 18 (solid black line, dot on map) and October 28 (dashed black line, star on map) in the top 120 meters of the ocean near Hurricane Melissa's track segment from October 27. That track segment is represented by the short dashed purple line on the inset map, and it's short due to Melissa's slow forward speed on that date.

Echoing colleagues: Think before you (re)post. #Melissa is about to impact a relatively poor part of Jamaica. I doubt we will know the true extent of the devastation for days or weeks. Information vacuums fill with disinformation. Expect a lot of “breaking wind” on SM. Map source: World Bank

Y'all - this is literally insane. I am pretty sure that I have never seen automated satellite intensity estimates this high on an Atlantic hurricane. Dvorak T-numbers approaching 8.5 are almost always with west Pac supertyphoons. Graphic from UW-CIMSS.

#Melissa, an extremely powerful and intense hurricane, has made it into the upper echelon of Atlantic hurricanes in the modern aircraft reconnaissance era, based on maximum flight level winds. At 161 kt, it is currently tied at #14 with Ivan (2004), Dorian (2019), and Milton (2024).

Jamaica has low storm surge risk—not a lot of low-lying areas. An exception: Kingston’s Norman Manley International Airport (built on fill), Soapberry Wastewater Treatment Plant, Portmore Mall, Jamworld Entertainment Center, the National Gallery, Petrojam Refinery, Caribbean Maritime University.

If we had crossed paths with a serial child abuser, we simply would not have hand-drawn him a naked woman or given him a birthday card. This does not seem difficult. The Epstein files must be released, and Trump must be impeached. He is unfit.

As a #MarshallFire survivor, I'm very glad to see that #BoulderCounty is upgrading their sirens and expanding their use to a variety of hazards, including wildfires. Sirens are particularly helpful for people who are outdoors, like my wife and son were the day of the fire.
Press release from Boulder County about the coming upgrade to the county's outdoor warning sirens. Quote from the press release: "At the request of first responders, these sirens may be used for alerting affected areas during wildfires, floods, hazardous materials and other disasters," said Office of Disaster Management Director Mike Chard.

Due process matters more than we think. Let's send a message loud and clear to the Trump Administration: - Follow the law - Obey court orders - Stop deporting permanent residents to foreign concentration camps - Bring #KilmarAbregoGarcia home!
