Nearly 100 homes flooded in Houston area HOUSTON, July 14 (UPI) -- Heavy rain in the Houston area, where as much as 15 inches have fallen in five days, led to flooding of nearly 100 homes, officials said. The rain pushed Cypress Creek well above its flood stage and higher than it had been during Tropical Storm Allison in 2001, the Houston Chronicle reported. "It's going to get worse before it gets better," Francisco Sanchez, a Harris County spokesman, said as Cypress Creek continued rising Friday afternoon. More than 3 inches of rain fell Friday in a 3-hour span ending about noon. The heaviest rains may be over, but the National Weather Service said an upper-level low-pressure system isn't moving out as quickly as expected, and that could bring heavy rains Saturday and Sunday. More heavy rains could mean severe flooding because soil in the region is saturated and many of the bayous are already at high levels, the Chronicle said. WHOU-TV, Houston, reported a 40 percent chance of rain Saturday and Sunday. The heavy rains led to high water on some roadways, and Houston spokesman Michael Walter said city firefighters rescued seven people who had driven into high water across the city. Officials with the Harris County Office of Emergency Management said motorists who encounter high water should turn around. Officials urged residents not to walk or play in floodwaters, which often contain sewage, fire ants and snakes.
