The I-35 corridor and Hill Country remained under the threat of sudden flash flooding on Sunday, requiring residents across the region to keep a close eye on the weather, especially if outdoor gatherings were involved.
A flood watch was in effect for Bexar and surrounding counties and the Hill Country, including flood-ravaged Kerr County, until 7 p.m.
The National Weather Service reported an additional two to four inches of rain, and up to 10 inches in some pockets, could fall in the watch area during that time.
The erratic movement of the storms overhead has made this latest round of storms especially dangerous, sometimes appearing as bumper cars on radar, colliding and spinning in circles over the same areas. Such movements make it hard to predict where the heaviest showers will fall. The ground is already saturated, so flooding can happen fast.
There remained a strong chance of showers for Kerr County through Sunday, followed by minor chances on Monday and Tuesday. There was only a minor chance of rain for San Antonio for Sunday through Tuesday.
Drier air is expected to move into the area on Tuesday that should begin a drying trend that should last into next weekend.
