Houston Soaked By More Rain One Day After Massive Flood

After a deluge of up to 11 inches lead to massive flooding of streets, freeways and bayous Monday night into Tuesday, another line of thunderstorms with torrential rain descended through the metro, particularly over areas along and north of Interstate 10.

The National Weather Service issued flash flood warnings for parts of Harris, Chambers, Liberty, Montgomery, Liberty, Waller, Washington, Austin, Grimes, Polk and San Jacinto Counties early Wednesday morning. 

Rainfall rates of just over 2 inches per hour were measured by Harris County Flood Warning System gauges on the northern border of Harris County early Wednesday morning. A pair of gauges northwest of Beltway 8 along Cypress Creek measured over an inch of rain in 15 minutes.

High water was reported on the Tomball Parkway northbound as well as U.S. 290 in both directions near Beltway 8 early Wednesday. Exit 78a on Interstate 45 was closed due to high water near Shenandoah in Montgomery County.

According to Harris County Flood Control, Little Cypress and Lower Cypress Creeks rose above bankfull at Becker Road and at Cypresswood, respectively. 

Fortunately, the line continued to sag south through most of the metro area, including much of the flood-ravaged areas of Harris County during the Wednesday morning commute. Thus, the threat of widespread additional flash flooding appeared to be over for the rest of the Houston metro.

However, the western end of the line did stall out over parts of Waller, Austin and Colorado Counties, with rain rates up to 2 inches per hour estimated by Doppler radar.

Officials in other parts of Texas and the southern Plains have warned that river flooding could last for weeks as some areas have seen more than 20 inches of rain during May. Several cities have already seen their wettest May, or even month, on record.

As always, stay informed about the latest flood watches and warnings for your area. If you are in a vehicle and encounter a flooded roadway, do not attempt to drive through the water. From 1995-2010, 64 percent of flood-related deaths occurred in vehicles. The National Weather Service stresses: Turn around, don't drown.
