Update, 4 p.m. Monday: As of 4 p.m., storms are moving through North Texas – and heavy rain is likely. The storms will make for a slick rush hour, and rain is forecasted for the evening.
Most of North Texas will see some rain, but the eastern half of the region will get the most. Expect 2 to 3 inches across parts of Dallas and Collin counties, as well as to the east and south of Dallas. There is a slight risk of severe storms -- large hail and strong winds are possible.
The National Weather Service has issued a flash flood watch for the eastern half of Dallas-Fort Worth from 4 p.m. Monday through 5 a.m. Tuesday. The watch includes Dallas County, as well as Collin, Rockwall and Ellis counties. It also includes other counties to the east and south of Dallas.
Areas that received heavy rains Thursday are most at risk for flooding and runoff due to the moisture already in the soil, the weather service says. Flooding is possible in creeks, small streams and urban areas.
A separate flood warning has been issued starting Monday night through Wednesday for parts of Hunt County -- the Cowleech Fork of the Sabine River in Greenville, as well as the south fork of the Sabine River near Quinlan.
The river should rise above flood stage by Monday evening, the weather service says. Some road closures may take place.
As of 4 p.m., about 40,000 North Texas customers were without power, but that number includes outages that aren't weather-related.
