It was the second day of turbulent weather in Texas, where at least four people died Friday in flood waters in central Texas.
The storms and suspected tornadoes, which forecasters say were caused by an upper-level disturbance from Mexico, socked an already-sodden swath of Texas that was still drying out from the remnants of Hurricane Patricia.
In the Houston area, some locations had received nearly 12 inches (30 centimetres) of rain since Friday, though it had mostly stopped by yesterday afternoon. The water flooded streets and freeway frontage roads and caused bayous to spill over their banks.
Houston officials also said they had received 44 reports of structural flooding, including homes and businesses, and the city's fire department helped remove residents from flooded homes near a bayou in the northeastern part of the city.

Houston police discovered two bodies that are believed to be weather-related deaths, one in a flooded ditch and another in a wooded area where there had been high water, according to city spokesman Michael Walter.
As the storms moved east yesterday, National Weather Service meteorologist Patrick Blood said a tornado went through Brazoria County near Alvin at about 5 am (local time), damaging about 25 mobile homes in the community that's 30 miles (48 kilometres) south of Houston.
Thirty minutes later, a tornado hit the Houston suburb of Friendswood, where about 30 homes had minor damage and the roof of one home was ripped off. David McCullough, 70, who lived in the most severely damaged home, said he and his wife were out of town when the storm hit and he got the call from a neighbour.
The NWS rated the tornado as an EF-2 when it first touched down, which can spawn winds of up to 150 mph (241 kph).
Between 10 and 30 homes were damaged by a tornado in a subdivision in eastern Harris County at about 7 am yesterday, Blood said.
