High water and flooding were reported in north and northwest Houston Tuesday morning, after the Harris County Flood Control District reported between 1.12 and 8.32 inches of rainfall across the region from Monday to Tuesday morning.   A flash flood warning remains in effect until 8 a.m. Wednesday as the National Weather Service is forecasting a 60 percent to 70 percent chance of heavy rain for the region. Houston TranStar's map showed the largest concentrations of high water on roadways in the Jersey Village and Greenspoint areas but the highest rainfalls were recorded in western Harris County, near the Harris County, Fort Bend and Waller counties' junction. The city of Katy's gauge near Buffalo Bayou Cane Island Branch and Hwy. 90 recorded 7.92 inches of rainfall in 24 hours as of 7:54 a.m., while other flood gauges in Harris County Precinct 3 recorded between 5.88 and 8.32 inches in that same time frame. The city of Katy's Office of Emergency Management alerted residents on social media to be mindful of high water on roadways but Emergency Management Coordinator Maria Galvez said all city streets were passable as of about 6 a.m. "We got some pooling in some areas, some hot spots," she said. "The water receded rather quickly."
Galvez said no property damage was reported to the city as of about 9 a.m. Tuesday but that some people had posted on Facebook about water reaching their homes' entryways. "It could have been worse," she said. Meanwhile, Harris County Precinct 3 received larger amounts of rain but managed to stave off most flooding. One exception was the Bear Creek subdivision, which is located north of Clay Road in Houston and straddles Hwy. 6. "That was [caused by] the underground drainage system being overwhelmed by the rainfall," HCFCD meteorologist Jeff Lindner said. Around the region, social media users posted images of high water in their areas:
