MOST ACCURATE FORECAST: Monsoon storm chances continue this week in the Valley

Monsoon storm chances continue this week in the Valley

PHOENIX — Chances for monsoon storms are in the forecast all week!

In fact, we're expecting to tap into some remnant moisture from Tropical Storm Lorena which will really ramp up storm chances Wednesday through Saturday across Arizona.

Here in the Valley, we could see a few storms this evening, but our next best shot at widespread rain will be late Wednesday night through Thursday morning.

Air quality is also still a concern. An Ozone High Pollution Advisory is in effect through Wednesday.

Breathing in ozone pollution can cause chest pain, coughing, throat irritation, congestion, and difficulty breathing. Children, older adults, and those with respiratory conditions such as asthma, bronchitis, or COPD are especially at risk. To stay safe, limit time outdoors during the afternoon peak.

Everyone can help reduce ozone pollution by carpooling, using public transportation, working from home, avoiding long drive-thru lines, and waiting until after dark to refuel gas-powered vehicles.

2025 Sky Harbor Official Rainfall to date: 1.97" (-2.84" from average)

Monsoon 2025 Sky Harbor Official Rainfall: 0.50" (-1.39" from average)
