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.

@DrPaulDEgerton @UNEP @UN ... and chaos created by Trump’s executive orders and rhetoric in international order and peace

[Brad Panovich @wxbrad]

This will literally bankrupt the U.S. If you ever wondered why NOAA/NWS is in the department of commerce, I have some news for you. Every single $ of our economy is impacted by the weather. Agriculture, Energy, Travel, Logistics, Defense, logistics of every major company, etc I could go on but you get the idea. Seems like this will quickly get reversed, we can hope.

NEW: The Trump admin has informed NOAA that two buildings that are critical for weather forecasting will have their leases canceled. If this comes to pass, it's a really big deal. Includes weather fcst nerve center in College Park, Md.: https://t.co/MAzRvzMLrZ

We have taken our Artificial Intelligence (#AI) Forecasting System into operations today to run side by side with our physics-based weather forecasts. The #AIFS outperforms traditional models for many measures, at a fraction of energy use. Read more ➡️ https://t.co/18f61f4cve

@ianhanomansing Sorry I did not like the booing of the USA anthem at the 4Nations hockey yesterday. It’s disrespectful, like burning a nation’s flag. Good hockey is best.

Wow. Bishop Mariann Edgar Budde fearlessly calls out Trump and Vance to their faces. This is heroic.

[Tomer Burg @burgwx]

It's no exaggeration to say today brought a truly historical weather event to the Gulf Coast - lots of places all the way down to the water got over 6-8 inches of snow, shattering records going as far back as 1895 in some places.

Let's review what caused this historic event 🧵

A little concerned for the LM and Victoria tomorrow AM as models have settled down into a compact, convectively driven low crossing the Georgia Strait tomorrow AM, lifting NE. This pattern can produce a short burst of locally damaging W-NW winds.
