PHOENIX — Monsoon storms are hitting Arizona again!

Here in the Valley, watch out for gusty winds, blowing dust, heavy downpours and lightning with any storms that move through.

The Valley is also under an Ozone High Pollution Advisory through Thursday. Kids, older adults and people with respiratory conditions, like asthma or COPD, should limit time outside during the day or breathing may be difficult.

A disturbance moving through northern Mexico will enhance our monsoon storm potential even more for the rest of the week and into the weekend.

Valley storm chances will increase to 70 percent Thursday, Friday and Saturday.

With the chance of widespread heavy downpours, the flood potential is going to be high.

Much of Arizona is under a Flood Watch on Friday and Saturday.

If you live near any of our wildfire burn scars, stay alert and get your property sandbagged now. Do not attempt to drive through any flooded areas. It only takes 1 to 2 feet of moving water to carry your vehicle away.

Stay tuned for more updates over the next few days.

Higher storm chances will also help drop temperatures. Look for highs in the 90s across the Valley by Friday and over the weekend. Early morning lows will fall into the 70s.
