The primary risks include isolated heavy downpours, strong winds, and flash flooding, particularly in low-lying and flood-prone areas. Rainfall totals in the San Antonio metro area are expected to range from 1 to 2 inches through Tuesday, with isolated areas potentially receiving over 4 inches, especially east of the city. Slow-moving storms could exacerbate flooding risks. Residents in South-Central Texas should remain alert to changing weather conditions and monitor updates from local authorities.
