PHOENIX — Another storm system is moving into Arizona, bringing more rain, winds and a big cool-down on Wednesday!

Wednesday is an ABC15 Weather Action Day as the rain will impact your outdoor plans and travel across Arizona. Flooding is also a concern, especially near creeks and streams in northern Arizona. Take action and prepare for the risk, especially if you live in flood-prone areas.

Widespread light to moderate rain, with a few embedded thunderstorms are likely in the Valley through Wednesday afternoon.

Strong thunderstorms could fire up in the Valley and across northern Arizona late Wednesday evening and night as a cold front moves in.

Rainfall will end up at a quarter to half an inch around the Phoenix area. 

In northern Arizona, snow levels will stay relatively high with this storm system, so spots like Flagstaff will pick up rain rather than snow on Wednesday. We could see as much as one to two inches of rain across northern Arizona.

This rain will impact the snow that's on the ground in the high country, causing quicker snowmelt and more runoff that could lead to flooding.

Flood Alerts are in place for Oak Creek in Sedona and Cornville, Wet Beaver Creek in Rimrock and Lake Montezuma, Tonto Creek near Punkin Center, and the Salt River in the Valley.

Flood Watches are in effect for the lower elevations across Yavapai and Gila counts, and across much of Mohave county from Wednesday morning through Thursday evening.

These areas could see minor to moderate flooding due to runoff from the rain, and snow melting in the high country.

While snow levels remain near 8,000 feet on Wednesday, they'll drop to nearly 6,500 feet early Thursday morning.

Light snow showers are possible in spots like Flagstaff as this storm system starts clearing out.

After reaching highs in the 80 the last several days, this storm will bring a dose of cool air, dropping highs into the upper 60s to low 70s through the end of the week.
