Due to mass confusion, clarifying again:

Tsunami Watch: Tsunami of indeterminate magnitude is possible; stand by.
Tsunami Advisory: Tsunami is likely *but will probably be small.* Evacuations unlikely.
Tsunami Warning: Tsunami is likely *and may be large.* Evacuations needed.

"When you tear down a scientific enterprise, rebuilding it is not as simple as rehiring." — CIRES Director Waleed Abdalati discusses the impacts of cuts to NOAA with @axios.com Boulder.

You’ve been illustrating for Owen?!! Amazing 🤩

Lmk if you find something that works bc same!!

Hrrr afternoon run quick to try to develop the disturbance off the SE coast. Regardless stormy pulses will overspread FL through midweek as the system moves into / across the northern Gulf.
Maybe #Dexter later this week? @WFLA

That’s a pretty disingenuous opinion. You’re entitled to your own thoughts but the folks who remain at the NWS offices are doing everything they can to continue to protect their community’s lives and property as per their stated mission with the resources they have in this current environment.

I thought the same thing when I got the notification

I discussed these WEA alerts in my post on Friday, and showed how to turn those on too: bsky.app/profile/hale...

However there are some differences. The WEA is typically only used in catastrophic/emergency situations. The Weather app notifications probably includes all warnings for your location.

Your iPhone weather app now has @nws.noaa.gov notifications for things like tornadoes and flash floods alerts. Here’s how to turn them on for your location and any other locations you want to track plus an example of what one looks like.

…in the future I’ll try to keep these to three minutes or less, so they aren’t split into multiple posts!

If you have any questions I’m happy to answer in the comments 😊

Part 1: Happy Friday! It’s morning (mountain time) I’m sipping some coffee and just wanted to talk to you all about Wireless Emergency Alerts, why they are important, how to turn them on on your phone and just have a simple discussion.

This video is split into two parts…

I am positive it’s not cloud seeding 😉

Thanks @climatecentral.org and @climate.noaa.gov (RIP) for the graphics

I’ve been working on sharing some basic climate science in video format (mostly on Instagram). But hey why not share it here too. :)

Line graph showing observed and predicted temperatures (black line) in the key ENSO-monitoring region of the tropical Pacific from spring 2025 through the fall.

Today is the top of the month release of the NOAA CPC ENSO diagnostic discussion (EDD), and it will be the first time in 11 years that Climate.gov isn't releasing an associated ENSO blog update. It would have contained an updated version of this graph. [1/4]

These people care way more than anyone knows and way more than they ever get credit for 💔

And many other line offices within NOAA (like the Climate Program Office and several others) have already lost their entire communications staff in the last several months. The value of having great communicators is often overlooked until it’s not.

Heavy Rains Cause Deadly Flooding and Evacuations in Texas

Your occasional reminder that climate change makes intense rain events more intense.

At this point, the question is not "did climate change affect this" but instead "how much of an affect did climate change have?"

June 2025 #Arctic sea ice extent was the 2nd lowest on record for the month...

This was 1,280,000 km² below the 1981-2010 average. June ice extent is decreasing at about 3.68% per decade. Data: @nsidc.bsky.social (nsidc.org/data/seaice_...).

Looks like my last article for climate(.)gov got pushed out last week. End of an era but glad this did get published. Give it a read!

Very much so, our team is very saddened about this decision. Thank you for the kind words of appreciation, it helps.

You understand Dan, thank you for the kind words ❤️

Sad to see that leadership didn’t approve of my suggested post language (assuming since this is what is posted) that I submitted on my last day in May as the social media manager.

Allow me share some of our team’s kind words here instead:

I sought comment from NOAA and the Department of Defense on this and received this reply today from NOAA's spokesperson. They suggest we use the surviving ATMS microwave that degrades significantly at the edges. You can see how much worse off we'd be with Erick last week if we only had ATMS.

I have been working on a pretty cool (at least I think so) personal project this week...
Check out my portfolio website! haleythiem.myportfolio.com

Structural changes, like the development of an eyewall, are detectable in microwave images well before they are in visible or infrared images. It can tip off forecasters to the onset of rapid intensification, which as we've seen plenty of times, can occur shortly before a storm makes landfall.
