He closed all city buildings and canceled the State of the City address set for Monday. The Houston Independent School District was also closed on April 18.
15 people, caught in the flash floods were rescued by the Houston Fire Department in the early morning on April 18, and another 6 people were rescued from the cars captured by the water in Waller, the county's emergency management office reported.
Residents were repeatedly warned that getting caught by the deep and fast-moving flood water will cause almost certain death and were advised to stay home wherever possible.
According to the weather forecast, heavy rainfall and strong thunderstorms will continue to threaten areas from eastern Texas to the Dakotas. Scattered thunderstorms could still develop in southern Texas until the end of the day and bring damaging wind gusts, hail and isolated tornadoes.
Snow is expected to continue in the higher elevations of Colorado and northern New Mexico, parts of Wyoming, eastern Utah and extreme southern Montana throughout the day. On April 19, the snow may still linger in the higher areas of Colorado, Utah and Wyoming.
