PHOENIX — Monsoon moisture is flowing in and chances for storms are increasing across Arizona.

Here in the Valley, our best storm chances will be Wednesday afternoon and evening.

Watch out for lightning, heavy downpours, gusty winds and blowing dust with any monsoon storms that develop.

A High Pollution Advisory has already been issued for Wednesday due to lingering dust in the air and chances for more to blow in.

Flood Watches are in effect for much of southern Arizona, including parts of southern Pinal County and Pima County, on Wednesday. If you are traveling in these areas and encounter any flooded roadways, do not attempt to drive through them. Remember to "Turn around, Don't drown" and find another way to get where you are going.

There's also a heightened risk of wildfires sparked by lightning across Arizona over the next few days.

Stay safe and check for frequent updates on our monsoon storms here on abc15.com.

Storm chances will gradually decrease as we approach the Fourth of July and clear out of our Valley forecast completely by Saturday and Sunday.
