Rain and possible flooding are in the forecast. Stay weather aware! A message from La Marque Office of Emergency Management.
Tropical moisture moving into the area Sunday and Monday bringing periods of heavy rainfall.
3+"/hour rainfall rates will be likely along and south of the Interstate 10 corridor leading to street flooding. Run up on the beaches will cause strong rip currents and beach flooding.
A tropical wave over the western portions of the Yucatan Peninsula will move slowly northwestward today and move back out over water. Currently the National Hurricane Center doesn't have this system developing in the next 5 days. The wave should track to the northwest and will eventually pump deep tropical moisture into SETX Sunday through Tuesday. The rain chances should be higher toward the coast with the most intense rainfall focused mainly south of the Interstate 10 corridor. Widespread accumulations of 1 to 3 inches is likely through the course of the event but the focus should be on the intense rainfall rates Sunday PM-Monday evening. Isolated amounts in excess of 5 inches will be possible where storms train.
Coastal and Marine
A long onshore fetch will produce seas of 5 to 8 feet near shore and 8 to 11 feet offshore with isolated seas possibly approaching 12 feet. Rough surf conditions and strong rip currents are also expected. Elevated tides and wave run up will be possible at times of high tide with some minor coastal flooding possible along the Bolivar peninsula Sunday and Monday.
Urban Flash Flood Messaging
Heavy rainfall is forecast for portions of Southeast Texas, including highly urbanized areas like the Houston metropolitan area. Based on forecast conditions, NWS Houston will be utilizing the following urban flash flood messaging for this event:
- Drive with caution. Cars may flood in low-lying areas. Ponding on roadways may increase risk of hydroplaning.
- Pay attention to the weather. Monitor NWS, HCFCD, and TranStar for current conditions.
- Rain may move repeatedly across the same area, causing a rapid rise on creeks and bayous. However, creeks and bayous are not likely to exceed their banks.
