Multiple hazards to monitor heading into Thursday
Both a Flood and Severe Thunderstorm Watch in effect
BRYAN, Texas (KBTX) - Sunday night’s storms left the Brazos Valley ground extremely saturated, especially areas east of Highway 6. In anticipation of yet another round of widespread rain that could be heavy at times, the National Weather Service has issued a Flood Watch.
Wednesday evening update: With widespread thunderstorms already starting to fill into the area and intensify, A Severe Thunderstorm Watch has also been issued until 2am Thursday morning.
Though quarter sized hail and wind gusts 50mph+ are still possible with the strongest storms we see tonight into Thursday, the primary concern is still for flooding, which could make more than a few headaches for Thursday morning’s drive.
Latest data can be found on the KBTX Weather app, online, and on air as necessary through the overnight and right into Thursday.
Wednesday evening data suggests the more widespread rain and thunderstorms are expected to develop out west and move into the Brazos Valley through the overnight hours. While severe weather will also be possible, some of the stronger storms will be capable of dropping multiple inches of rain in a short amount of time. This is especially a concern for those who saw storms this morning, especially across our northern counties.
The main concern will be for hazardous driving conditions due to flooding. Some of the hardest hit areas of the Brazos Valley picked up nearly a foot of rainfall Sunday night through early Monday. It does not take much to reaggravate those flooded areas, and we look to receive more than enough to cause issues. Widespread totals with this evening sit between 2″-4″ with isolated areas potentially able to collect 5″-8″ under the strongest and heaviest storms. As storms dissipate through sunrise Thursday, additional time will be needed for waters to recede, hence the Watch lasting through Thursday evening.
As of Wednesday morning, the Storm Prediction Center has upgraded the Brazos Valley to a level 2 out of 5 risk for severe weather Wednesday afternoon through Thursday morning. The latest high resolution model data has three different rounds of storms moving through the Brazos Valley in this time period.
- Round one will be scattered storms moving into the western portions of the Brazos Valley as early as 3:00pm Wednesday afternoon, becoming more widespread throughout the evening, and clearing to the east closer to 10:00pm.
- Round two will be moving in from the northwest as an organized line of strong storms. Exact timing still needs to be ironed out, but it looks like our northern-most counties could see rain and rumbles as early as 2:00am. The line will continue to move to the southeast through the morning, exiting our southern counties around sunrise.
- Round three is forecast to move into northwestern counties around 9:00am, pushing over Bryan-College Station closer to 10:00am, and exiting San Jacinto and Montgomery Counties by lunchtime.
The primary concern with each round will be flooding. However, all severe hazards are possible. Additional updates can be found wherever you get your information from the KBTX Weather team, including the app.
