Severe weather warnings are changing in 2028. It's a major update for the United States when it comes to alerts like Tornado Warnings and Severe Thunderstorm Warnings. Today, @NWS handles a long-lasting storm with a series of separate warning boxes, each issued one after another. Each box can last up to about 45 minutes. A storm can also cross from one NWS office’s area into another’s, which means a new warning has to be issued. The catch? Two neighbors a few miles apart can get very different notice. If you’re just outside the next box, you may have to wait for the next warning before you’re alerted. Enter “Threats in Motion.” This approach replaces the stack of boxes with one warning that moves with the storm. Here’s what changes: 📍 More equal lead time: Everyone downstream gets a fairer heads-up, not just the people in the next box. 🕐 Regular updates: The same warning is updated every 10-15 minutes, and forecasters adjust the shape, direction, and timing as the storm changes. 🛡️ Fewer gaps: On busy nights when forecasters are tracking several storms, a long-track storm stays warned. ✅ A built-in “all clear”: Warnings drop off places the threat has passed, so you know when it’s safe to come out of your shelter. The technology isn’t here yet, so today’s warnings still apply. Threats in motion is being built into a new operating system that NOAA and the NWS are adopting in 2028. This change has been a long time coming and solves a lot of problems we have in the warning process. It can't get here soon enough. #nwas26 #severeweather #weather
