SLIGHT RISK OF FLASH FLOODING TONIGHT THROUGH WEDNESDAY AM
Source: US National Weather Service Corpus Christi Texas
Timing and Overview
There is another threat of severe weather and flash flooding across South Texas tonight as a system moves through the region. With respect to the severe weather threat, the Storm Prediction Center has put portions of the Rio Grande Plains/Brush Country under a Slight risk (level 2 of 5) with the primary threat of damaging winds and large hail. A Marginal Risk exists for the remainder of South Texas outside of this region. With respect to the flooding risk, recent rainfalls have saturated the soils allowing for more efficient runoff. Under high rainfall rates and/or slow-movement with the strongest storms, these areas would quickly experience ponding and flooding of low-lying areas. Small streams and creeks will also respond quickly with locations like the Aransas River near Skidmore and the San Fernando Creek near Alice forecast to enter action/minor flood stage as of the latest West Gulf River Forecast center morning update.
South Texas Hazards
Rainfall: 1.0-2.0" isolated up to 3-5"
Winds: Isolated gusts between 60-70 mph
Hail: Up to 1.0 inch
Tornado: Non-zero chances for isolated tornado
South Texas Impacts
Severe
Damaging Wind Impacts
(Low Impact, Winds 59-73 MPH): Damaging winds may cause dangerous driving conditions for high profile vehicles. Damage to mobile homes, porches, and awnings is possible. Large fallen trees may produce isolated to scattered power outages.
Hail Impacts
Hail greater than 1” may cause damage to vehicles in the form of chipped paint, dented body panels, and broken windshields. Damage may also occur to vegetation and roofing shingles. Anyone caught outdoors could face serious injury.
Heavy Rain/Flooding
Scattered flash floods possible. Mainly localized with urban areas, some roads and small streams most vulnerable. A few low-lying structures flooded. Storm drains and retention ponds become full and may overflow in a few places. Flood waters may cause several road closures.
Forecaster Considerations
While difficult to pinpoint the exact areas where the highest rainfall totals will be, the West Gulf River Forecast Center has advised that given the latest rainfall forecast, the Aransas River near Skidmore is currently projected to rise back into minor flood stage Wednesday, May 27th. Should the greatest rainfall rates/amounts fall over this basin, there is a possibility that moderate flooding (13 ft) would be possible. Confidence in this is outcome is low, but it is worth monitoring as the storms develop and move overhead tonight.
