FLOOD WATCH issued overnight for majority of the Brazos Valley
Localized 5″ or more could fall in a short amount of time between the Central Brazos Valley and I-10
BRYAN, Texas (KBTX) - The National Weather Service has issued a FLOOD WATCH for a majority of the Brazos Valley Saturday night. An unseasonable April cold front is expected to spark widespread rain and strong thunderstorms, utilizing an abundance of atmospheric moisture to create localized heavy rain over a short period of time.
- WHAT: A Flood Watch means conditions favorable for flooding, caused by excessive rainfall, are possible
- WHO: Austin, Brazos, Burleson, Grimes, Houston, Madison, Montgomery, San Jacinto, Trinity, Walker, Waller, and Washington Counties
- WHEN: 4pm Saturday - the overnight hours, ending before sunrise Sunday (unless extended by the National Weather Service)
- IMPACTS: Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations. Flooding may occur in poor drainage and urban areas.
The cold front sparked up initial shower development through Saturday afternoon. As the front continues to sag southward through the rest of the evening, the Brazos Valley remains in a moisture-rich environment. As of the six o’clock hour, there have been four Flood Advisories issued areawide as heavy rain rates put down estimated totals upwards of 2″ quickly with training storms anticipated. Those additional rain and thunderstorms are then expected to become widespread after sunset through 10 pm as this cool airmass behind the front continues to slip in.
The rounds of rain that have already fallen have left the grounds oversaturated. Multiple reports of standing water in backyards and on roads have been noted. There are even some road closures because of high water across roadways, including in the 11000 block of Southbound Wellborn Road, where two outside lanes have been closed.
While the overall severe threat is low/minimal, elevated thunderstorms behind the cold front could produce hail up to pocket-change size and wind gusts in excess of 40mph. Storms along the cold front itself could may also create brief gusts between 30 and 50mph as the wind shift moves south-southeast.
