PHOENIX -- Widespread rain and some mountain snow is in the forecast across Arizona through Sunday,as a storm that has already hit California moves eastward, the National Weather Service said.
Forecasters say rain through Sunday morning could total nearly 1 inch in Phoenix, 2-3 inches in Flagstaff and Payson, and nearly 1 inch in Tucson.
The rain could put a damper on outdoor events scheduled around the city this weekend, including spring training baseball games, the Phoenix Marathon, a downtown Phoenix Mardi Gras Parade and a beer festival in Tempe.
As of Friday, Metropolitan Phoenix has gone 69 days without any significant rain. However, meteorologist Ken Waters said that streak isn't anything out of the ordinary for this time of the year in the desert.
"It's a bit of a long streak yes but we've actually had some that were longer," Waters said.
Still, the dry winter months have left Phoenix's main reservoir system at low levels. The reservoirs are typically filled before spring with runoff from snowmelt. Lake Roosevelt, the biggest in the system, is only 48 percent full, Waters said.
Forecasters say snow levels at elevations above 6,000 feet will range from 2 to 6 inches with higher amounts possible in some areas. Flagstaff, at an elevation of 7,000 feet, could get between 2 and 5 inches of snow on Saturday, Waters said.
The weather service said the risk of flooding is low.
