I have been working on a pretty cool (at least I think so) personal project this week...

I’ll check the weather machine and see if we can add some more flurries 😆

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.

A graphic with text overlaid on the U.S. La Niña winter impact map. The text reads: "A weak La Niña is less likely to result in typical La Niña winter impacts. However, it could still influence the 2025-26 winter season."

A map of North America showing the typical weather patterns during a La Niña winter. A blue arrow shows the polar jet stream dipping southward over the northwestern U.S., bringing colder and wetter conditions to the Pacific Northwest and northern U.S. A "blocking high pressure" system is shown off the West Coast. The southern U.S. is shown with warmer and drier conditions.

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.

A bar chart titled "ENSO Probabilities, Issued October 2025." It shows the percent chance of La Niña (blue), Neutral (gray), and El Niño (red) conditions for different three-month seasons from September 2025 to July 2026. The chart indicates a high probability of La Niña in the fall, decreasing over time, while the probability of neutral conditions increases beginning in January 2026.

A La Niña Advisory has been issued, meaning that La Niña conditions have been observed in the tropical Pacific Ocean.

Wow 😮
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.

Climate.us @climate.us · 27d

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.

Most of the U.S. is getting a nice break this Labor Day weekend from the summer heat, but there are some exceptions – mainly in the west. Check out what's in store for you this weekend at weather.gov.

It was truly an honor to interview two Hurricane Directors two decades after Hurricane #Katrina. One was at the helm during the storm, while the other leads today.

The most profound lesson that emerged from our conversation?

The critical importance of communication.

3 Ways Hurricane Forecasts Have Changed Since Katrina

Modern technology has given meteorologists more detail than they’ve ever had on how storms behave. Here’s what they’re doing with it.

I am happy to be supporting the NWS in my new role with new content like this!

Areas of heavy rain are possible from the southern Plains to the Gulf over the next few days as we work through the holiday weekend. Check your latest, local forecast at weather.gov before heading out.

As someone who used to make 3D for tv, 100% agree lol

Haley Thiem @haleythiemwx.bsky.social · Aug 27

While I agree it is cool and different, to a lay person it could suggest rainfall as high as building, no?

The experts have been busy monitoring these events and adapting to prevent even worse flooding and devastation through Juneau during these now seemingly yearly events.

Haley Thiem @haleythiemwx.bsky.social · Aug 13

The barriers mentioned here are what adapting to our changing climate looks like in real time!

For the third August in a row record Mendenhall Lake has exceeded its record gauge height following a glacial outburst flood.

Corinne Smith @corinne-smith.bsky.social · Aug 13

Juneau officials say there were no reported rescues or injuries, and damage to homes is still being assessed.

The Hesco barriers were largely successful and did their job, though there were a few reported hits by trees. Damage also reported to the Back Loop Bridge which is still closed.
