Over the last 24 hours, the Cy-Fair area has seen rainfall amounts varying between 1-4 inches, causing creek levels to rise but largely stay within their banks, according to data from the Harris County Flood Control District.
A flash flood watch remains in effect for the entire southeast Texas region, according to the National Weather Service. The watch is expected to run through 7 p.m. Saturday, May 11, but NWS officials said adjustments could be made.
Another round of storms is expected late May 10 through mid-day May 11. However, the NWS Weather Prediction Center downgraded its excessive rainfall risk from “moderate” to “slight” on Friday morning.
“Rainfall today should be in the 0.5 to 1 inch range which should not cause further flooding problems but may make flood waters slow to recede,” NWS officials said in a May 10 release. “For now we think the highest rainfall will be along the coast and this is where the flood threat will be highest.”
Rainfall totals overnight Friday are expected to fall within the 1-3 inch range with potentially higher totals in localized areas, according to the NWS.
Several high water points have been reported along Houston roads by TranStar—including on FM 2920, the Hardy Toll Road and parts of I-45 North—but no major road closures have been reported in the Cy-Fair area due to flooding.
CenterPoint Energy reported 103,000 power outages during the peak of the storms. As of 11 a.m., the company reported 37,710 still without power, including outages scattered across the Cy-Fair area and an estimated 320 outages in the Steepleway area.
