Monsoon storm chances are back!

PHOENIX — Monsoon moisture is flowing into Arizona and storm chances are back!

Our best bet for rain here in the Valley will be overnight into Wednesday morning and again Wednesday night into Thursday morning.

That’s when we could also see all the typical monsoon threats, like gusty winds, blowing dust, frequent lightning strikes, heavy downpours and even flooding.

Temperatures will drop, too.

Much of the Valley will only top out in the upper 90s to low 100s Wednesday and Thursday.

We could see a few more spotty storms on Friday before storm chances taper off over the weekend as drier air moves in.

Up north, more widespread monsoon activity will impact the high country throughout the week and over the weekend. Watch out for the possibility of flash flooding near any wildfire burn scars.

A Flood Watch is also in effect across parts of southern Arizona on Tuesday afternoon and evening. Do not attempt to drive through any flooded areas there. The road may be washed away underneath the flood waters. Stay safe and remember, “turn around, don’t drown.”
