Tropical Storm Bertha has formed in the Gulf of Mexico and is moving northwest toward the southeastern United States, according to the report.
The National Hurricane Center said the system strengthened into a tropical storm after NOAA Hurricane Hunters confirmed maximum sustained winds of 40 mph.
The report said Bertha is expected to bring widespread rainfall of up to six inches, with isolated areas receiving as much as eight inches through Friday, increasing the risk of flash flooding along parts of the Gulf Coast.
According to the report, Bertha is not expected to cross into the Atlantic Ocean, but moisture from the storm could interact with a weather front near North Carolina's Outer Banks later this week, potentially producing additional heavy rainfall across the Carolinas.
