Austin, Texas – Drivers along Interstate 35 have a narrow window to prepare before isolated severe thunderstorms erupt between 2 p.m. and 9 p.m. Wednesday, bringing the risk of large hail up to 1.5 inches and wind gusts near 60 mph.
According to the National Weather Service in Austin-San Antonio, a Level 1 out of 5 severe weather risk covers much of South-Central Texas this afternoon and evening. Storm development will depend on whether clouds thin enough to allow the atmosphere to destabilize. If storms form, they could quickly intensify with large hail, damaging wind gusts and locally heavy downpours.
The greatest impacts are expected along and east of the I-35 corridor from Georgetown through Austin, San Marcos and New Braunfels, extending toward San Antonio. Travel on I-10 and Loop 410 could become hazardous during heavier storms, with sudden visibility drops and ponding water on roadways.
Heavy rain may overwhelm poor drainage areas in a short period of time, especially during the late afternoon commute. Drivers should slow down on wet pavement and avoid flooded low-water crossings.
Residents are urged to secure outdoor items, monitor weather alerts and have multiple ways to receive warnings before storms develop. Conditions will quiet down later tonight, but additional updates or warnings may be issued quickly if severe cells materialize this afternoon.
