MERCEDES - The Texas Department of Public Safety is warning the public to slow down when driving on wet roads. 

Troopers are not only watching the roads, they're also rescuing those stranded in flood waters.

DPS Lt. Johnny Hernandez says, "safety is a concern and we want the public to just keep flowing. We want to make sure they get home safely."

He says they rescued more than 15 people in just one neighborhood.

One resident who has lived in Mercedes for more than 30 years says he didn't even see floods this bad when Hurricane Dolly hit.

KRGV's Taylor Winkel walked alongside Lt. Hernandez through the rescue efforts which took place in Mercedes.
