Occupants of a houseboat that was adrift in Lake Travis in Austin were rescued early Friday.

Austin-Travis County EMS say the 21 occupants of the boat were not injured and were being evacuated with rescue boats.

Responders say the houseboat broke free from Sandy Creek Marina earlier in the day. EMS used three boats to attach the houseboat to the dock at the marina.

The National Weather Service has issued a flash flood warning for parts of Travis, Williamson and Bastrop counties until 4:45 a.m.
