Aug. 28 (UPI) — The National Hurricane Center issued a tropical storm warning for parts of Louisiana Monday afternoon as Tropical Storm Harvey moved off the coast of Texas.
In its 10 p.m. update, the NHC said the center of the storm was located in the Gulf of Mexico 70 miles east of Port O’Connor, Texas, and 145 miles southwest of Port Arthur, Texas. Harvey’s winds picked up speed from 40 mph up to 45 mph as it reached the gulf. It was moving east-southeast at 3 mph.
The storm was expected to move “erratically” east-southeast through Monday night before turning northeast Tuesday. The center of the storm was forecast to be offshore through Tuesday night.
A tropical storm warning was in effect from Mesquite Bay, Texas, east to Intracoastal City, La. There was a storm surge watch in effect for Port Bolivar, Texas, to Morgan City, La. If Harvey’s wind speeds drop below 40 mph, it becomes a tropical depression.
Tropical-storm-force winds extend outward up to 175 miles, primarily over water to the east and northeast of the center, forecasters said.
After Harvey moves off the coast, it is projected to return to a northeasterly track and pass from southeast Texas and southwest Louisiana up through east Texas and the entire northern portion of Louisiana.
Harvey weakened into a tropical storm as it moved inland Saturday, but the NHC said it was becoming an “extremely serious flooding event.” Harvey made landfall near Corpus Christi Friday night as a Category 4 hurricane. By 6 a.m. Saturday, it had weakened to a Category 1 hurricane with 90-mph winds. By midday, it was reclassified as a tropical storm.
Harvey was the first major hurricane to make landfall in the continental United States since Hurricane Wilma hit Florida in October 2005. It was also the first hurricane to make landfall in Texas since Ike in 2008.
The NHC is also watching Tropical Cyclone 10, which was stationary off the U.S. Southeast, which has maximum sustained winds of 35 mph. A tropical storm watch is in effect for parts of South Carolina and North Carolina.
The cyclone is expected to become a tropical storm Tuesday morning.
“The system is expected to produce total rain accumulations of 3 to 6 inches along the upper South Carolina, North Carolina, and southeast Virginia coasts, with possible isolated maximum amounts of 9 inches,” the NHC said in a statement. “The heavier rains may result in some flooding concerns along coastal areas.”
