Lowland flooding expected in Lake Houston areas
Houston City Councilman Dave Martin said the city is monitoring potential flooding as water levels continue to rise in the West Fork San Jacinto River after rain storms last night.
Showers and thunderstorms Thursday morning produced rainfall at up to 1.5 inches per hour. Tide levels are above normal, and streets could be slow to drain, meteorologists said.
The West Fork San Jacinto River could exceed the top of its bank by Saturday evening and cause minor lowland flooding in the Lake Houston area, according to National Weather Service.
Martin said city officials have been releasing water from Lake Houston since Christmas Eve in anticipation of Thursday morning’s storm. However, the top of bank of the river is 49.30 feet and the water level is still expected to reach 51.3 feet by this weekend.
The Harris County Flood Control District advises that that heavy rainfall of 3-4 inches overnight across a large portion of the San Jacinto River watershed on top of wet grounds will lead to significant rises along the East Fork of the river from Plum Grove downstream to south of FM 1485 and low lying areas along the West Fork downstream from U.S. Hwy 59 to West Lake Houston Parkway.
The river is expected to rise to flood threshold levels by Friday morning at both FM 1485 and U.S. 59 near Humble and Kingwood and may remain near or above the flood stage into early next week.
City officials ask residents to be alert and use extreme caution when traveling.
The City of Houston and Harris County will continue to monitor and provide updates as they become available.
