Morning satellite loop of the very strong Nor'Easter producing powerful winds and very heavy snow across the Northeast. Blizzard conditions and crippling impacts will continue through much of today for the region. 🛰️❄️

CSU has released its Atlantic seasonal #hurricane forecast verification. 2025 was an above-normal season per NOAA, but with an unusual distribution of storms (e.g., fewer storms but more strong hurricanes) than typically expected given overall activity:

More/better Hurricane Melissa videos now that the furlough/gov shutdown is over and I can get the go ahead to post revised versions. What was originally posted three weeks ago were quick edits/crops exported in 720p which were good enough but not all that they could be. I will include a link to YT so those inclined can watch in 4K. Today I’m posting thread from pass 5 which was approx 1645-1648Z time.

This first one is GoPro Max footage that I finally got around to editing. It starts very similar to the post from a few weeks ago but with a twist. 1/5

Fifty years ago this month, the largest Hawaii earthquake of the 20th and 21st centuries occurred. Earthquake shaking, as well as ground subsidence and local tsunami, contributed to a catastrophic sequence of events on November 29, 1975.

I just created a quick map depicting which portions of the United States are now (as of today) or will imminently be (by early June) without 24/7 local National Weather Service coverage (per Washington Post reporting). #CAwx #CAfire #CAwater #ORwx #AKwx #WYwx #KSwx

The 2026 budget passback plan calls for eliminating NOAA Research, the scientific backbone that keeps weather forecasts, alerts, and warnings accurate and effective. This would have disastrous consequences.

Earthquake sum up 3pm (Mynamar/Thailand)
- 7.7 quake hit near Mandalay/Myanmar
- Hundreds of homes collapsed (various Myanmar cities)
- Strong shocks in Thailand + multiple building collapse in Bangkok
- USGS predicts thousands of people dead

(Bangkok clips from social media:)

This figure informs us about the historical and current seismicity in Myanmar especially in the Sagaing fault. Also, the Mag 7.7 was strongly felt until 2000 km where massive damages can be found in Thailand.

Some pre shower activity ahead of the front continues to move north towards the San Juans/Strait of Juan de Fuca areas. When thunder roars, go indoors!

A first look at the thunderstorm threat for B.C. for Wednesday PM-overnight. Can't ignore some of the soundings south of the border and storms remaining organized through the late-evening. #BCstorm

[World Meteorological Organization @WMO]

Today marks the much-anticipated #WorldMeteorologicalDay. Reports now show that 55% of countries have multi-hazard early warning systems, though gaps remain. It’s time for decisive #ClimateAction—let’s come together to close the early warning gap.

It’s a very shallow earthquake.

[Mount Washington Observatory (MWOBS) @MWObs]

On Mount Washington, this afternoon we are currently sustained between 125mph and 135 mph with frequent gusts into the 140s. Our indoor barograph is literally off the chart due to the high winds acting as suction out of our doors. Our peak wind gust of the day, thus far,...
