NEW ORLEANS — A storm system that left widespread damage and some injuries in its wake in Texas is drifting into Louisiana, Mississippi and Alabama.
Strong to severe thunderstorms will charge in Tuesday late afternoon and evening with a threat of damaging wind gusts, large hail and a few tornadoes.
The severe threat on Tuesday will be highest in our most northern parishes and counties, but severe storms are possible all across our area including New Orleans and coastal spots.
Louisiana’s federal and state authorities reminded thousands of hurricane survivors living in government-provided mobile homes and recreational vehicle trailers to have an evacuation plan ready as the structures might not withstand the expected weather.
