Officials in Hays County and the City of San Marcos are bracing for potential flooding and bad weather from Hurricane Harvey.

Emergency officials say the most important thing for people to do right now is watch the weather because as the storm continues to develop the level of severity will become more clear. Nonetheless, Hays County is known as "Flash Flood Alley" meaning areas of the county can flood in the blink of an eye.

Thursday emergency crews in San Marcos and Hays County worked to make sure the barricades and sand bags they use to block off low water crossings are ready to be loaded up. They're identifying shelters, gassing up vehicles and outlining plans. And they recommend everyone in the area do the same.

"Make sure you're aware of what your evacuation routes will be if we do have a flooding situation," said Jeff Caldwell, Director of Neighborhood Services for the City of San Marcos. "Make sure that if you've got neighbors that you know of that may not be able to get themselves out, that they have a plan of action. If you have a place to go where you don't have to come to the shelter, that actually helps with the resources we have for the people that have no place to go."

Caldwell said people should make sure they have gas in their vehicles and have flash lights and batteries on hand. He also recommends people head over to and register their cell phones and computers to get emergency alerts. It's a free service that provides alerts for ten counties.

People who live in San Marcos are encouraged to also sign up for alerts at and listen to the City's FM radio station, 103.1. Another good website to watch is
