    What is a severe thunderstorm warning?

    Thunderstorms are common in Arizona, particularly during the state’s monsoon season, which runs from June 15 to Sept. 30. The monsoon brings intense heat, surges of moisture and atmospheric instability, creating afternoon clouds and increasing the chance of storms.

    Although storms occur most frequently during the monsoon, they can develop in Arizona at any time of year. Some storms are isolated and brief, while others can produce strong winds, lightning and torrential rain.

    A severe thunderstorm warning means an area is experiencing or is about to experience a storm with winds of 58 mph or higher and/or hail at least 1 inch in diameter.

    How to stay safe during Arizona thunderstorms

    • Go indoors at the first sound of thunder. Lightning can strike miles away from the parent storm.
    • Wait 30 minutes after the storm passes before resuming outdoor activities.
    • Avoid using electronics and plumbing, and stay away from windows.
    • Bring pets indoors.
    • If there is time, secure loose objects outside because they can become dangerous flying debris in high winds.
