The National Weather Service is reassuring people after a tsunami warning alert was mistakenly issued from the Gulf Coast to the East Coast.
The warning went out on some weather apps just before 8:30 a.m. Eastern Time Tuesday, and was reported in areas from New Orleans and Houston to Palm Beach, Florida to Maine.
The alert said a tsunami warning was in effect.
About 20 minutes later, Accuweather tweeted that the push notification was just a test.
