WEATHER UPDATE

BOTTOM LINE: Regional Flash Flooding and River Flooding from heavy rainfall are possible from as early as tonight through Tuesday.

CHANGES SINCE LAST UPDATE: Flash Flood Watch has been expanded to include all inland areas of southeast Texas.  This Flash Flood watch is currently in effect through 7 AM Tuesday.

Forecast Rainfall Amounts through Wednesday – An average areawide 3 to 5 inches; locally higher amounts of between 8 to 10 inches.

Area of Greatest Threat – Flooding from high rainfall, generally over the western forecast area. The most recent forecast has the highest rainfall occurring along Highway 59, from the city of Houston southwestward.

Other Threats – There is a marginal threat for severe thunderstorms over all of Southeast Texas tonight and Monday. The primary severe weather hazard will be damaging winds, frequent cloud to ground lightning and excessive rain. Due to continued moderate southeast winds, coastal flooding will occur along western portions of Galveston Bay and Gulf facing beaches, especially during times of high tide. Water has already moved over Bolivar Peninsula and Galveston Island’s local roadways. Water has already impacted the Kemah Boardwalk and will likely rise again in Seabrook along Toddville Road during this evening’s high tide.

Confidence: Moderate – Widespread showers and thunderstorms are expected across the region through Tuesday, but which communities will see the highest rain totals will be driven by smaller scale features which will be difficult to pinpoint.

ANOTHER UPDATE SHOULD BE OUT AROUND MIDNIGHT
