Flooding is a possibility in San Antonio Wednesday as roughly an inch of rain is expected to fall on the Alamo City, according to the National Weather Service.
Bexar County, along with several others in the region, have been placed under a flash flood watch until 7 p.m. Flooding on low water crossings is expected, as are rises in already-swollen area creeks and rivers, according to the forecast.
This round of rain is caused by an upper level disturbance that’s interacting with moisture left over from Hurricane Willa, according to the National Weather Service.
Though the amount of rain expected is relatively low, the saturated ground makes flooding more likely. Forecasters are also concerned about the Hill Country, which has dealt with rounds of flooding in the past few weeks.
Rain will persist through most of Wednesday and into Thursday morning.
After that, clear skies and sunny weather is in store for the weekend.
