The National Weather Service warns of dangerous flash flooding in the Dallas-Fort Worth Metroplex.
More than 7 inches of rain fell within 24 hours at the Dallas-Ft. Worth International Airport.
The water has left roads flooded and cars submerged and stranded on highways.
"A lot of these are high water calls. Water is just rising faster than they anticipate so a lot of these cars are stranded, people in their vehicles but we do have also some flooding to where it's coming in their house maybe their elderly, handicapped, they're on special life support equipment that they need help moving out," said Lt. Joseph Martinez of Dallas Fire-Rescue
According to WFAA in Dallas, there were at least 23 crashes in Fort Worth overnight and at least one water rescue.
"Be safe and NEVER drive through flooded roadways," the National Weather Services reminded motorists.
The flooding threat in Dallas is expected to subside Monday. The National Weather Service forecast says scattered showers and storms will move south.
