The heavy rain event could lead to isolated street flooding, hazardous low-water crossings, and rapid runoff in flood-prone areas during heavier downpours. Reduced visibility and hazardous driving conditions are expected, particularly in Bexar County. Minor rises in local creeks and drainage channels are possible, and flash flooding risks are elevated across South-Central Texas. The Coastal Plains may see elevated river and creek levels into early Tuesday, with the risk area potentially expanding in future updates.
