Tropical Storm Bertha Forms in Gulf of Mexico

The storm was drifting erratically south of the Florida Panhandle, with forecasters warning of storm surges up to 4 feet along the Louisiana and Mississippi coasts.

Heavy rainfall could cause flash flooding in low-lying areas, and isolated tornadoes are possible.

Meanwhile, Hurricane Fausto formed in the eastern Pacific, though it poses no immediate threat to land.

Authorities urged residents to prepare emergency kits and monitor updates.
