As of 4 p.m. Sunday evening, creeks in the Tomball and Magnolia areas had exceeded capacity, according to rainfall amounts from the Harris County Flood Control District. Here is a look at creek levels from Tropical Storm Harvey as compared to 100- and 500-year flood levels. According to the city of Tomball, Hwy. 249 is closed at the Spring Creek bridge, as the roadway is impassable. The Montgomery County Office of Homeland Security and Emergency Management as well as the Montgomery County Sheriff's Office have warned residents of rising water levels throughout Spring Creek. The sheriff's office has recommended affected residents evacuate. Willow Creek is also out of its banks in Tomball. While Spring Creek is not yet to its May 2016 level, the creek is out of its banks. Willow Creek has surpassed its 100-year flood level by about a foot of water. No records were available for Spring Creek's level during Tropical Storm Allison in 2001. However, the creek is approaching its level during the April 2016 floods. In Hockley, rainfall totals more than 20 inches since Friday evening. Little Cypress Creek surpassed the 500-year flood level as of Sunday afternoon. For updated rainfall information, visit the Harris County Flood Warning System.
