Texas is set for its first bout from the tropics on Tuesday after Tropical Storm Harold formed early Tuesday morning, producing top winds of 45 mph, as of 4 a.m. CT. The National Hurricane Center issued a tropical storm warning for an area along the Texas coast from the mouth of the Rio Grande to Port O'Connor. A section from Port O'Connor to Sargent is under a tropical storm watch. Because it is quickly moving at 18 mph, the storm located about 155 miles off the coast won't have much time to gain strength. The National Hurricane Center expects Harold to come ashore Tuesday as a tropical storm. Once it reaches land, Harold is expected to weaken quickly. A widespread area of Texas is expected to receive 3 to 5 inches of rain with some areas topping 7 inches. Areas under the tropical storm warning could also experience 1 to 3 feet of storm surge, the National Hurricane Center warned. Forecasters said tornadoes are also possible through the afternoon. The Atlantic Hurricane Season has been a little more active than usual. Harold is the eighth named storm of the year.
