A Houston fire spokesman says firefighters responded to at least 50 calls for water rescues after heavy downpours and thunderstorms hit the area.
Spokesman Jay Evans says most of the calls Saturday came from motorists who mistakenly drove into high water and became trapped. He says there have been no reports of injuries or deaths.
The Houston Chronicle reports that officials are warning people to stay off the roads. Flood Control District officials reported as much as 6 inches of rainfall in some parts of Harris County in three hours, mostly in the west, southwest and central parts of the area.
County officials say at least three bayous and creeks are close to capacity, which could potentially cause surrounding streets and low-lying areas to flood.
