Storms bringing the snow

VALLEY - A strong winter storm is moving into Arizona.Over the next 24 hours, expect heavy snow to develop above the 5000 foot level of northern Arizona and heavy rain to move into the deserts.

Winter Storm Warnings are posted in northern Arizona and the Tim Country, were some areas could see 15-30 inches of snow.In the deserts, rainfall estimates for the Valley are in the rain of one inch.

And that's just round one.

Monday evening commuters ran into 2 snags along the Tempe corridor, one at McClintock and Don Carlos that took out a street sign and required extrication.

The other was at Apache and Rural, resulting in an SUV slamming into a bus stop and causing heavy back-up along Rural due to the road closure.

On the tail end of the first surge, a second strong storm will move into Arizona.This storm will be slightly warmer, so the snow levels will be higher.It has the potential to produce more heavy snow.However, flooding may become a problem as rain is forecast to fall on top of the snow from round one in storm areas.That could produce the rapid runoff of water.Look for Flash Flood Warnings to be added to the Winter Storm warnings by the middle of the week.

And in the deserts, round two could bring another inch of rain to the Valley.All in all, it's going to be a very wet week around Arizona.
