Large parts of the US will see very bad weather over the next couple of days. If you're traveling in an unfamiliar area and conditions worsen, you can load wx4.me on your smartphone and it can use your GPS location to tell you if you need to take shelter.

You should have multiple ways of getting warnings, like a NOAA Weather Radio or emergency alerts on your phone. You can also visit wx4.me from your phone to see if you're in the polygon!

Outdoor warning sirens are only meant to warn people who are outdoors! Do not rely on them for your safety.

Heads up to the mid-Mississippi and lower Ohio valleys! Confidence is increasing in a widespread severe weather event Friday evening (March 14) into early Saturday (March 15).
