TROPICS MOSTLY QUIET

The Atlantic remains unusually quiet for late August, with no organized tropical threat to Texas right now. There's a very low chance a brief weak tropical or subtropical system could form in the NE Atlantic over the next week. But it is headed towards Portugal and Spain and is not a threat to the U.S. We will continue watching the tropical wave train in the Atlantic as activity typically increases heading toward the peak of hurricane season in September.
