Flash Flood Watch in Effect for Parts of the Area

By  | 

A FLASH FLOOD WATCH is in effect for the Brazos Valley through 4pm Thursday as another round of showers and thunderstorms is likely for the area tomorrow morning.

6pm Update

The Flash Flood Watch has been extended through 4PM tomorrow afternoon. Another batch of showers is expected to push through in the morning hours and continue to linger on into the afternoon. Rain chances will gradually dwindle as the evening approaches.

12pm Update

Only rain left across the Southern Brazos Valley is a light steady rain in a few locations.

Focus will now be shifted to the northern half of the Brazos Valley where scattered strong storms have popped up in Milam County. While storms are not expected to become severe, there is a chance that any storm capable of dropping more than 1" of rain per hour could cause isolated areas of flash flooding. Main trend through the afternoon will be activity forming and then drifting to the south / southwest.

For now there are no immediate areas where high water is of concern in the area. We will continue to monitor radar trends though the afternoon. You can track the activity using Interactive PinPoint Radar.

11am Update

The Flash Flood Warning for the southern half of the Brazos Valley has been allowed to expire as scheduled.

Rain continues to fall but is slowly drifting to the south and falling coming down in intensity as well. Rainfall rates have fallen to below 0.10" per hour.

The FLASH FLOOD WATCH will continue as planned through 7pm. Scattered, strong thunderstorms will likely form just north of the area and then try to move south. Should rain fall faster than 1" per hour, there could be run-off due to already saturated ground, which could cause brief flash flooding.
10am Update

Radar activity has begun to slowly come down in intensity across the southern half of the Brazos Valley. While rain continues to fall -- some small pockets of moderate to heavy rain still present -- most of it has come down to below 1" per hour. Any flash flooding that may have occurred already will still be an issue -- but the good news is that the rain will slowly start to slow down and then end all together. Below is a look at the radar as of 9:57am and select rainfall rates across the Flash Flood Warning area:

8:15am Update

The FLASH FLOOD WARNING has been extended until 11am for Southern Grimes, North and Central Waller and Western Montgomery Counties. The FLASH FLOOD WARNING has also been extended to include most of Washington and Austin Counties until 11am as well.

Areas that could see quick rising water -- Navasota, Hempstead, Prarie View, Waller, Brenham, Bellville, Montgomery, Magnolia, Todd Mission.


A FLASH FLOOD WARNING is in effect for Southern Grimes, Eastern Washington, Northern and Central Waller and Western Montgomery Counties until 8:15 this morning.

Radar indicates that rain is falling at 1 to 3 inches an hour over the area under a Flash Flood Warning. That same area has had reports of localized 6 to 10 inches of rain over the past several days.

High water has been reported Hagar Road, Joseph Road and Fieldstone Road in Prairie View.

As of now, there have not been any reports of issues in the area. Be sure to take measures not to drive through water over flowing area roads.

If you have flooding pictures or reports please send them to weather@kbtx.com.


The National Weather Service has issued this watch for Austin, Brazos, Burleson, Grimes, Madison, Montgomery, San Jacinto Waller, Washington and Walker Counties.

A Flash Flood Watch means that conditions are favorable, with enough heavy rain falling, for flash flooding to occur. With heavy rains saturating the ground over the past few days, additional rains could run-off quickly and produce areas of flooding.

It is advised if you see water flowing over a road to turn around and find a different direction and route to take.

Today's forecast holds another 60% chance of showers and thunderstorms today. While the rain is much needed for the area, stronger storms could produce heavy downpours, occasional cloud-to-ground lightning and possible brief, strong winds.

More details will become available right here at KBTX.com should flash flooding become an issue through parts of the Brazos Valley. You can track the radar online on our Interactive PinPoint Radar.
