A hurricane watch is in effect for part of southeast Louisiana as Tropical Storm Sally moves slowly away from south Florida, the National Hurricane Service said.
The watch is in effect from Grand Isle, Louisiana to the Alabama-Florida border, including Lake Pontchartrain, Lake Maurepas and metropolitan New Orleans.
A storm surge watch is also in effect from the mouth of the Mississippi River to the Alabama-Florida border, including Lake Pontchartrain, Lake Maurepas, Lake Borgne and Mobile Bay.
Sally, the earliest named « S » storm in recorded hurricane season history, is forecast to move over the southeastern and eastern Gulf of Mexico Saturday night and Sunday, then move over the north-central Gulf Sunday night and Monday. It is expected to make landfall Tuesday along the Louisiana-Mississippi border, possibly as a Category 1 hurricane with winds up to 85 mph.
Currently located about 30 miles south-southwest of Naples, Florida as of 4 p.m., Sally is moving west at 7 mph with maximum sustained winds of 40 mph. The storm is expected to turn toward the west-northwest Saturday night. A west-northwest or northwestward motion is expected during the next couple of days
