Major rainfall fell on the Katy area, but the storms are expected to lessen, according to a 7 a.m. update from the National Weather Service May 10.

Between 1 to 6 inches of rain fell on the Greater Houston area May 9, and the NWS predicts rainfall May 10 will be between 0.5 to 1 inches. A flash flood watch is still in effect until 7 p.m. May 11. Katy-area schools are closed May 10.

According to a Facebook update from Wendy Duncan, the director of the Willow Fork Drainage District, the 24-hour rainfall totals as of 3:45 a.m. in the Katy area along Buffalo Bayou were:

  • 6.4 inches at the Barker Dam;

  • 4.8 inches at Peek Road;

  • 2.32 inches at Greenbusch Road; and

  • 1.08 inches at the city of Katy.

Additionally, the Barker Reservoir was at an elevation of 83.71 feet at 3:43 a.m., Duncan wrote.

“[At 95 feet] and below elevation, water is stored on government-owned lands,” she wrote. “[The 97 feet elevation is the] lowest elevation of structures subject to flooding due to pooling in Barker Reservoir.”

According to a previous Facebook post by Duncan, hail and flooded streets were reported in the Cinco Ranch area in the evening of May 9.

The city of Katy Office of Emergency Management posted on Facebook around 2 a.m. that the strong and severe thunderstorms were pushing away from the region.

“We can expect light to occasionally moderate rain for the next few hours,” the department wrote. “There will also be a few lightning strikes and rumbles of thunder.”
