Tropical disturbance expected to bring heavy rain and potential flooding
The National Weather Service in Fort Worth advised it is closely monitoring a tropical disturbance in the west central Gulf of Mexico that is expected to move through central and northern Texas. This system, while relatively fast moving, has the potential to bring renewed flash flooding and river flooding to much of the area.
This system will be a prolific rain producer, and flash flooding will be a major threat Tuesday through Thursday morning.
The primary window for heavy rainfall over North and Central Texas will be 3 pm Tuesday through 6 am Thursday. 2 to 4 inches of rain is expected through Thursday. Some local areas will receive 4 to 8 inch amounts.
Flash flooding will be the dominant impact with this event, and could be quite significant where intense rainfall occurs Tuesday night, and again Wednesday night. A secondary impact may be the development of brief, spin up tornadoes in the outer bands of the tropical system Tuesday afternoon, evening, and early Wednesday.
The Weather Service said these kinds of weak, shallow tornadoes often develop very quickly, providing little opportunity for major lead times.
Forecasters do not expect any significant impacts from tropical winds.
Monitor the weather closely for later updates.
