A year to the day since the devastating flood of 2015 pummeled the Austin & San Antonio areas of Texas, other parts of Texas received in excess of 9″ of rain in 3 hours around Houston, accumulating over 12″ over 12 hours as the storm passed through the region. As of Friday, May 27th, 2016, two fatalities have been reported – 1 from drowning, 1 from heart attack after driving through high water. Local highways remain closed as riverbanks are not high enough to contain the resulting floodwaters. These images were taken just 24 hours apart in Brazos County.
More flooding anticipated
While many streams and rivers are seeing floodwater levels diminish, those areas downstream of the harder hit areas are now dealing with the added water flowing throughout the watersheds racing toward the Gulf of Mexico. The Advanced Hydrologic Prediction Service (AHPS) from NOAA observes and predicts river stage levels across the country. Each gauge has a chart that indicates what water levels would cause the river to overrun its banks and flood the surrounding areas. As shown below, the Brazos River is forecast to continue dropping while the West fork of the San Jacinto River (farther east, toward the Gulf of Mexico) is expecting to reach ‘major flood stage’ levels prior to returning to normal. The recently observed readings are shown on the left, leading up to the forecasted levels along the right side of each chart.
Additional damage and dangers
In addition to the widespread flooding, many reports of hail and tornado touchdowns spanned the area. Some local residents in Bryan, TX took cell phone videos as the tornado passed through the Wheeler Ridge neighborhood. As the weather clears and river levels return to normal, the damage and impact can begin to be addressed. More flooding and tornadoes are forecast across the Southeastern US in the next few days as the storm system continues moving east.
