Floodwaters pummel southeastern Texas • Earth.com

Just six weeks after being drenched by record-setting rainfall, much of southeastern Texas has been inundated again by a seemingly endless stream of slow-moving thunderstorm systems. Water levels on the Brazos River, near Houston, crested higher than they have in more than a century. The Texas governor declared states of emergency in 31 counties by June 1, 2016.

The Operational Land Imager (OLI) on Landsat 8 acquired these images of southeastern Texas on May 28, 2016 (top) and May 4, 2013 (second image). The top image shows flooding along the Brazos River just west of Monaville, while the second image shows the river when it was well within its banks. In 2014, the river nearly ran dry in places due to drought. The images below from the same days show the wider scale of the flooding.

On June 2, 2016, the Brazos River rose to 54.81 feet, according to gauges near Richmond, Texas. (The previous record was 50.30 feet on October 21, 1994.) Downstream at Rosharon, the river reached 51.97 feet; anything above 51.3 feet is considered major flooding at that point. Forecasters expect water levels to remain high for up to three weeks because more storms are predicted for early June and because swollen reservoirs upstream will need to release water.

The intense rainfall capped off the wettest month in Texas history, with a state average of 7.54 inches. The previous record was 6.66 inches in 2004. According to news sources, Texas was doused with more than 35 trillion gallons of rain in the month. Meteorologists attribute the wet spring to lingering effects of El Niño and to kinks in the jet stream that have slowed down weather systems while drawing in moisture from the warm Gulf of Mexico. Houston has received 24.84 inches of rain since March 1; the norm is 11.64 inches.
