Summary: Heavy rainfall over the past 24 hours has caused flooding in South, West, and Northern Texas.
Widespread rainfall amounts of 2 to 4 inches, with isolated areas of greater than 9 inches, have fallen over a significant part of the state of Texas over the past 24 hours. An additional 2-4 inches is predicated over the next 12 to 24 hours. As a result, significant flooding is occurring in south, west, and northern Texas.
10 streamflow stations are currently above National Weather Service Flood Stages, with additional sites expected to continue to rise as more precipitation falls over saturated areas of the state.
The majority of sites currently effected are in the San Antonio, Austin, and Fort Worth areas. The NWS expects that flooding will begin to move downstream along the Trinity River as excess flows in the Dallas-Ft Worth Metroplex begins to propogate downstream.
USGS staff are responding and making discharge measurements from multiple offices; 2 crews from Austin, 1 crew from San Antonio, 2 crews from San Angelo, and 3 crews from Fort Worth. An additional crew from Fort Worth are flagging high-water marks at multiple locations. One streamgage (08059590 Wilson Ck dws of Hwy 75 at McKinney, TX) has been damaged and is being visited to repair or install temporary equipment.
USGS crews are providing information to local, state, and federal partners, including the National Weather Service and the Corps of Engineers.
