As steady rain continued to fall throughout Yavapai County Friday afternoon, emergency officials advised residents in at least one area to evacuate.
The Yavapai County Sheriff's Office started advising residents of low-lying areas along the Agua Fria River in Black Canyon City to evacuate at 4:30 p.m. Friday.
Emergency personnel had to rescue two people from that river when the driver of a sport utility vehicle tried to traverse a low-water crossing at approximately 4 p.m. Friday. Law enforcement agencies had not yet set up blockades to warn drivers of rising water levels.
Personnel from the Black Canyon City Fire District and the Yavapai County Sheriff's Office rescued the people from the vehicle that was slowly floating down the river.
The widespread rain started on Thursday and the National Weather Service expects it to continue today.
By 5 p.m. Friday, the National Weather Service had issued a flash flood warning for much of Yavapai County through 8 p.m. Friday, and a flash flood watch for the entire county through this afternoon.
The Weather Service already was getting reports of flooding Friday in the Bagdad and Castle Hot Springs areas of western and southern Yavapai County, said meteorologist Dan LeBlanc at the Weather Service's Flagstaff station.
The strong storm came in from the south and dumped 3.3 inches of rain on Crown King as it rose from the desert into the southern Bradshaw Mountains during the 24 hours preceding 3 p.m. Friday, the National Weather Service reported.
The Weather Service also received reports of 1.97 inches in Bagdad, 1.32 inches in Cherry, 0.85 inches on the northwest side of Prescott, 0.85 inches in Oak Creek Canyon and 0.62 inches in Camp Verde by 3 p.m. Friday.
As of late Friday afternoon, the Weather Service expected the rainfall to increase Friday night and Saturday during the daylight hours, LeBlanc said.
At that time, the Weather Service was anticipating two to three inches of rain in the Prescott area before the storm tapers off Saturday evening.
