Saw my first tornado today. Taken on 2657 south of Oakalla, TX.
A picture of a tornado on the far side of a rear flank downdraft. A fenced in field is in the foreground with some trees. A couple of storm chasers stand near the fence watching the storm.

The Blackland Prairie here in Texas covers roughly 18,750 square miles, or 12 million acres. It’s a surprisingly narrow but very consequential slice of Texas, once among the most fertile grasslands in North America, and now one of the most heavily altered by farming and urban growth.

Fjallsárlón revealing the sharp, sculpted ice of Fjallsjökull — a landscape shaped by centuries of slow, silent movement, now retreating faster than ever.

A glacial scape at Fjallsárlón in Iceland shows towering, jagged ice formations rising from the lagoon, their surfaces shimmering in shades of white, turquoise, and steel blue. Behind them stretches the vast, rugged expanse of the Fjallsjökull glacier, textured with deep creases and snow-covered ridges under a low, misty sky. The still water in the foreground reflects the icy scene, adding to the stark, frozen beauty of the landscape.

Working in Dr. Howie Bluestein’s lab was one of the greatest privileges of my life. I am humbled to be part of the elite club of his former grad students. We celebrated his career and retirement last night at the NWC.

4 days of seismic records from a seismic station in Jamaica shows Hurricane Melissa roaring towards the island.

Hurricanes increase the amplitude of ocean waves which beat on the coast and sea floor. These produce Rayleigh waves that can be seen as increasingly thick “wiggles” in seismic records 🧪
Seismic recording that shows horizontal lines with a slight wiggle to them. Horizontal lines across the page that get thicker with wiggles near the bottom of the page. The horizontal lines are very thick. The page is almost black because of the thickness of the lines.

A 9am EDT update from the National Hurricane Center puts Melissa's sustained winds at 180 mph and moving NNE at 7 mph towards Jamaica, where it is expected to make landfall within the next few hours. Visit hurricanes.gov for the latest.
1. Jamaica: Remain sheltered! Catastrophic flash flooding, landslides, and destructive winds will continue through today, causing widespread infrastructure damage, power and communication outages, and isolated communities. Total structural failure is possible near the path of Melissa’s center. Along the southern coast, life-threatening storm surge and damaging waves are expected through the day. Failure to act may result in serious injury or loss of life. 2. Haiti and the Dominican Republic: Catastrophic flash flooding and landslides are expected across southwestern Haiti and southern portions of the Dominican Republic through midweek. In Haiti, extensive damage and isolation of communities is likely. Tropical storm conditions are expected later today and Wednesday. 3. Eastern Cuba: Heavy rainfall, flash flooding and landslides are expected soon. Life-threatening storm surge and damaging winds are likely to begin later today. Complete all preparations now. 4. Southeastern and Central Bahamas and the Turks and Caicos: Hurricane conditions, life-threatening storm surge, and heavy rainfall are expected across portions of the southeastern and central Bahamas on Wednesday. Complete preparations by tonight and follow local official guidance. Tropical storm conditions, heavy rains, and significant storm surge are expected in the Turks and Caicos Islands on Wednesday.

DISCUSSION AND OUTLOOK----------------------At 200 PM EDT (1800 UTC), the eye of Hurricane Melissa waslocated near latitude 16.5 North, longitude 78.3 West. Melissa ismoving toward the west-northwest near 3 mph (6 km/h). A slow turn toward the northwest and north is expected later today, followed by a turn toward the northeast and a faster forward speed on Tuesday. A northeastward motion is expected on Wednesday and Thursday. On the forecast track, the core of Melissa is expected to move over Jamaica tonight and early Tuesday, across southeastern Cuba Tuesday night, and across the southeastern Bahamas on Wednesday. Reports from an Air force Reserve Hurricane Hunter aircraft indicate that maximum sustained winds are now near 175 mph (280 km/h) with higher gusts. Melissa is a category 5 hurricane on the Saffir-Simpson Hurricane Wind Scale. Some fluctuations in intensity are likely before Melissa makes landfall on Jamaica on Tuesday. However, Melissa is expected to reach Jamaica and southeastern Cuba as an extremely powerful major hurricane, and will still be at hurricane strength when it moves across the southeastern Bahamas. Hurricane-force winds extend outward up to 30 miles (45 km) fromthe center and tropical-storm-force winds extend outward up to 195miles (315 km). The minimum central pressure estimated from the latest Air Force Reserve Hurricane Hunter aircraft data is 906 mb (26.76 inches). HAZARDS AFFECTING LAND----------------------Key messages for Melissa can be found in the Tropical CycloneDiscussion under AWIPS header MIATCDAT3 and WMO header WTNT43 KNHC. WIND: Tropical storm conditions are occurring in Jamaica, andcatastrophic and life-threatening hurricane-force wind conditionsare expected to begin tonight and continue into early Tuesday.Within the eyewall, total structural failure is likely, especiallyin higher elevation areas where wind speeds atop and on the windwardsides of hills and mountains could be up to 30 percent stronger. Tropical storm conditions are expected to begin in eastern Cuba onTuesday, with hurricane conditions expected to begin in thehurricane warning area by Tuesday evening. Tropical storm conditionsare expected in Haiti late Tuesday and Wednesday. Tropical storm and hurricane conditions are possible in thesoutheastern and central Bahamas, as well as the Turks and CaicosIslands, on Wednesday.

Catastrophic flash flooding and numerouslandslides are likely. For eastern Cuba, storm total rainfall of 15 to 20 inches, withlocal higher amounts, is expected by Monday into Wednesday resultingin life-threatening and potentially catastrophic flash flooding withnumerous landslides. Over the Southeast Bahamas, total rainfall of 4 to 8 inches isexpected Tuesday into Wednesday resulting in areas of flashflooding. For a complete depiction of forecast rainfall associated withMelissa, please see the National Weather Service Storm TotalRainfall Graphic, available athurricanes.gov/graphics_at3.shtml?rainqpf STORM SURGE: A life-threatening storm surge is likely along the south coast of Jamaica tonight and on Tuesday. Peak storm surge heights could reach 9 to 13 feet above ground level, near and to the east of where the center of Melissa makes landfall. This storm surge will be accompanied by large and destructive waves. On the northwest coast of Jamaica, near Montego Bay, there is the possibility of 1 to 3 feet of storm surge above ground level. There is a potential for significant storm surge along the southeastcoast of Cuba late Tuesday or Wednesday. Peak storm surge heightscould reach 7 to 11 feet above normal tide levels, near and to theeast of where the center of Melissa makes landfall. This storm surgewill be accompanied by large and destructive waves. Storm surge of 4 to 6 ft above normally dry ground is possible inthe southeastern Bahamas and Turks and Caicos Islands on Wednesday. SURF: Swells generated by Melissa are expected to affect portions ofHispaniola, Jamaica, eastern Cuba, and the Cayman Islands during thenext several days, and the Bahamas, the Turks and Caicos Islands,and Bermuda later this week.

The NOAA budget justification doc that finally was posted today didn't contain a lot of surprises - but as the first time all of the cuts were listed in their destructive detail, it is a depressing read. I tried to distill and explain the weather part, sad as it is.
