Yearly pre-winter reminder…
Record cold and snow in one area/region does not dismiss or invalidate the reality of long-term climate change. www.climate.gov/news-feature...

Are record snowstorms proof that global warming isn’t happening?
The United States has plenty of warming wiggle room before it gets too warm to snow, and a wetter atmosphere may boost snow totals for some storms.

Continuing to try to modernize some graphics for the NWS! But also good thing to check on winterizing your home before the end of the weekend/early next week cold snap!
Have you winterized your home this season? Here are some tips you can use to prepare your home for the cold weather coming. Learn more at weather.gov/safety.

Hearing atmospheric river? Want to know what all that is about? Watch this video!
If you live in the West, you’re likely to see the words “atmospheric river” pop up in the forecast over the next several days.
This is not a new term; in fact it was coined in 1994!
But what is an atmospheric river, and what weather hazards can you expect? Meteorologist Haley Thiem explains.

Really great article by a great former colleague @tdiliberto.bsky.social on what a weak La Niña could mean as far as snowfall goes this year, and the long term winter snowfall trend across the U.S.: www.climate.gov/news-feature...

Tropical Storm Priscilla will bring significant heavy rainfall to the Southwest over the next few days.
Remember it doesn’t take much water to sweep a human or even a car away. Be smart and avoid the danger that flash flooding can bring.

While La Niña is currently expected to remain weak, it could still influence the 2025-26 winter season. See what a typical winter La Niña pattern looks like across the U.S.

La Niña conditions are expected to continue through the December 2025 to February 2026 timeframe. A transition to ENSO-neutral conditions, meaning neither El Niño nor La Niña conditions, is most likely in the January 2026 to March 2026 timeframe.

Good question. This will be a full HTML version, as it was before it was taken offline.

I wonder if they mean a full working website as it was versus just a PDF. That would be really great, it was an amazing resource.
Especially the Art x Climate section which I used to highlight on C(.)gov socials every Friday for a time.

Exciting news update!
We’ve begun the process of cloning and migrating the NCA5 website to a new home & hope to make it public-facing in the next few weeks.
Your continued support sharing our campaign and donating will allow us to invest in the tools needed to secure these resources long term.

Life may be chaotic, but it’s important to take a moment when the weather is calm to make or check your emergency supply kit.
Make sure your food and water are fresh and all your supplies are working. If you stay ready, you don’t have to get ready.
