There were multiple water-covered highways in the Dallas metro area that required water rescues.

DALLAS FLOOD:

More than 450 requests for high-water rescues had been made since the previous night, and many of them were in progress by noon on Monday.

The National Weather Service said that flood warnings for Dallas and Tarrant counties are still in effect as of Monday at 4 p.m. CT (5 p.m. ET).

The warnings affect approximately 4 million Texans in Dallas, Fort Worth, and Arlington, and state that flooding in flood-prone areas, such as rivers and streams, is continuing or impending.

According to the Dallas Police Department, which has responded to rescue calls alongside the Fort Worth Fire Department and Dallas Fire-Rescue, hundreds of accidents have also been recorded.

The storm that caused heavy rain this past weekend is now issuing flood warnings for almost 15 million people from northeastern Texas through northern Louisiana and far southern Arkansas.

According to the National Weather Service, parts of Dallas received over 10 inches of rain between Sunday afternoon and Monday morning—enough rain to cover an entire summer.

National Oceanic and Atmospheric Administration claimed that, Dallas also received more than 3 inches of rain in only one hour of rain overnight, which is about a rainfall rate of 1 in 50 years.
