Monitoring the Situation
The NHC has issued an Area to Watch in the northwestern Gulf of America, with Houston and Corpus Christi under a Level 3 threat through Tuesday as flood watches are expanded.
While there are low chances of Tropical Storm Arthur developing, the risk of dangerous flash floods remains a concern.
Forecasters are closely monitoring the track and timing of the circulation area, as models suggest the potential for continued flash flooding through Friday and into the following weekend.
