The heavy rainfall poses a risk of flash flooding, particularly in areas under flood watches such as New Orleans and Atlanta. Urban areas, low-lying regions, and locations with poor drainage are especially vulnerable. Hourly rainfall rates of up to 3 inches could overwhelm drainage systems, leading to localized flooding. In southwest Texas, severe weather conditions, including hail and tornadoes, could cause property damage and pose safety risks. Residents in affected areas should remain vigilant and prepared for rapidly changing conditions.
