Harris County Sheriff Ed Gonzalez said dispatchers and deputies have counted approximately 400 reports of accidents on the icy roadways across the county.
Deputies said between 6 a.m. and noon alone, deputies and constables worked 115 car crashes.
Meanwhile, Houston Police Chief Art Acevedo said the city saw over 300 crashes in just nine hours.
Authorities say the road conditions are only going to get worse as temperatures dip and the sun sets on the Houston area.
If you do not have to leave your home, stay there and keep the roads open for first responders and emergency personnel.
