Sky News:- Storm Barry has made landfall in Louisiana and has weakened to a tropical storm after it was previously upgraded to a hurricane.
Officials have warned of a life-threatening surge of water to come with heavy rains that could last for several days.
The National Hurricane Center said the storm’s winds fell to 70mph as it made landfall.
The storm is the first major test of flood defences that were strengthened after Hurricane Katrina devastated the region 14 years ago.
Barry is the first tropical storm of the season.
The heaviest rains have hit coastal Alabama and Mississippi the hardest.
Dauphin Island Mayor Jeff Collier said parts of his barrier island in Alabama are flooded from both the driving rain early on Saturday and surging water from the Gulf of Mexico.
