PHOENIX - Showers producing moderate to heavy rain continue to develop and move across the valley tonight. Our coverage will be close to 100% as we head into the overnight hours.
An areal flood advisory is in effect for most of Maricopa county ( including the Phoenix metro) until midnight. Due to widespread light to moderate rain normally dry washes are running. Use caution traveling tonight.
In fact, a Flash Flood Watch continues and it includes the Phoenix metro, locations along the Rim and southwestern Arizona. Heavy rain could lead to flash flooding, especially in creeks and normally dry washes. Our washes are going to be active for the rest of the weekend, so use caution and remember never cross a flooded wash or street. Turn around, don't drown.
Valley rainfall totals ( that means since late Friday night to Sunday) will range from a half an inch to an inch with even more possible in the higher terrain just north and east of Phoenix. That's where we could see close to two inches of rain.
Further north, Winter Weather Advisories are in effect along the Mogollon Rim.
The precipitation has been mostly rain so far, but the snow level is expected to drop to around 6,000 feet by Sunday. Flagstaff could pick up 2 to 4 inches of snow.
Across Southeastern Arizona, Winter Storm Warnings are posted in the higher terrain for Saturday and Sunday. Places like Mount Lemmon and Mount Graham could receive 10 to 16 inches of snow!
Cool air has moved in too keeping overnight lows in the 40s and 50s with highs staying well below average in the low 60s on Sunday.
We'll start to dry out again next week as temperatures climb back into the 70s here in the Valley.
