The National Weather Service (NWS) issued a notice Monday morning, April 10, with an advisory for locally heavy rainfall possibility over portions of South Central Texas late this afternoon through Tuesday.
The greatest risk, said the NWS, is across the Hill Country and into the I-35 corridor (including both Austin and San Antonio metro areas). It is also possible for some of the higher rainfall totals to extend into parts of the southern Edwards Plateau and Rio Grande.
Rainfall of 1-3 inches is possible across that area, with isolated pockets of 5-7 inches. Some locations could experience flash flooding of small streams, creeks, and low water crossings. The rainfall could result in localized minor to moderate river flooding.
