Tropical depression in Gulf threatens Alabama, could become hurricane: Latest track maps

Tropical Depression Nine in the Gulf threatens Alabama and may soon become Tropical Storm Isaias. The US National Hurricane Center reports the system was 630 miles south-west of the Mississippi River mouth on Tuesday, with maximum sustained winds of 35 mph. Scientists predict it could be the Atlantic season's first hurricane, potentially the latest first hurricane since 1905. A possible US landfall is expected this Saturday as the system continues to develop and track.
