As rain continues to fall in the Valley--thanks to El Nino--emergency officials are watching and identifying areas where flash flooding could be a concern.
Flash flooding happens when rain falls faster than the ground can absorb it or makes its way down a storm drain. That's when you may see some ponding over roads or depressions fill with water.
If a roadway is flooded, turn around don't drown. If you choose to attempt to go across and need to be rescued, you could be fined using Arizona's Stupid Motorist Law.
Due to Thursday's rainfall, which areas have the highest threat for flash flooding?
According to the Maricopa County Flood Control District, areas in the north-northeastern parts of the Valley have the highest flooding threat level.
The western parts of the County--Tolleson, Surprise, Sun City, Glendale--have a "moderate" threat level.
The East Valley--Mesa, Gilbert, Chandler--have a "low" threat level for flash flooding.
