Storm warnings stretch from Florida to Louisiana as Bertha brings heavy rain, flooding risk and possible tornadoes
Tropical Storm Bertha strengthened in the Gulf of Mexico on Tuesday but was expected to weaken this week as it chugs closer to the US, potentially bringing coastal flooding and heavy rain from the Florida Panhandle to Louisiana.
Those areas along the northern Gulf coast were under a tropical storm warning through Wednesday and could see rain and flooding into Thursday morning, the Miami-based National Hurricane Center said. New Orleans also was under a tropical storm warning.
