October is here, and so is this week’s much-anticipated rainstorm. Starting strong Thursday morning, North Texas will see heavy rain through the rest of the day and into tomorrow. 

Much of North Texas is expected to get 2 to 4 inches, but some areas could see up to six inches of precipitation in the next two days. Dallas will remain under a flash flood warning through Friday morning. 

Months of above-average temperatures and almost no rainfall create a risk of flash flooding across many regions. North and Central Texas, along with multiple other states from Arizona to Iowa, have been under flash flood watches and warnings since late Tuesday night.

Scattered showers began in North Texas late yesterday afternoon and picked up early Thursday morning across North Texas.

The rain comes from the remnants of former Hurricane Polo, which made a second landfall along the northwest coast of Mexico on Tuesday and its initial landfall in Baja California Monday night. The storm was downgraded from a hurricane to a tropical storm before dissipating over Northwest Mexico Tuesday night. 

The streets around White Rock Lake have had the largest number of flooding incidents than anywhere else in Dallas in the last five years. The area around Dallas Love Field Airport, mostly around the intersections of Northwest Highway at Harry Hines Boulevard and Lemmon Avenue at University Boulevard, is the second most flood-prone area in Dallas. 

The approximate three-mile stretch of Interstate 35E from Northwest Highway to Interstate 635 has also been a problem area for Dallas drivers. 

Gov. Greg Abbott held a press conference on Monday where he announced that 1,900 responders and over 1,500 pieces of equipment, including water vehicles, search and rescue boats and helicopters, had been deployed. He also said the National Guard is activating more than 100 personnel and has another 400 on standby. 

Dallas officials have warned drivers not to drive into water and to report flood sightings or impaired roadways to 311.
