Major storm expected to drench Phoenix, most of ArizonaPosted: Updated:
PHOENIX -- Portions of Arizona are under a Flash Flood Watch as the storm that has been pummeling Southern California for a week heads our way.
Rain is expected to start this morning and increase as the day goes on. That rain will continue into the night.
The watch covers the areas of the lower Colorado River Valley, northwest Maricopa County, the southwest and west-central deserts and the Yuma and Martinez Lake area. That watch will remain in effect through Thursday morning.
Drivers need to be aware that roads could flood; they should not under any circumstances try to cross flooded roadways.
While morning rain is possible tomorrow, the storm should clear out by the afternoon.
The same system has prompted a Winter Weather Advisory for elevations above 7,000 feet. Between 4 and 8 inches of snow is expected in the eastern Arizona mountains.
That watch includes the White Mountains of Graham and Greenlee Counties and the community of Hannagan Meadow.
Snow levels will likely drop to between 6,000 and 6,500 feet Thursday.
Slick roadways could make driving hazardous.
