Moisture is being pulled in from the south, and as the daytime heating continues, showers and thunderstorms will become more widespread.

These thunderstorms will be slow-moving heavy rain producers, which could be particularly dangerous near burn scars. Heavy rain falling on top of burn scars could lead to mudslides and debris flows.

Monsoon season in the Southwest

The Southwest monsoon season begins June 15 and lasts through Sept. 30 each year.

Monsoon is a term given when winds blow tropical air toward typically desert locations, and Arizona and the Desert Southwest certainly qualify

7 FACTS ABOUT MONSOON SEASON

According to the National Weather Service, a ridge of high pressure in Mexico blocks any moisture from reaching the Desert Southwest in early June, allowing for days of hot, dry weather. Later in June and into July, the ridge drifts north into the Four Corners region of the U.S., allowing some tropical moisture to be carried northward from the Gulf of California and the Pacific Ocean.

Combine the desert heat with the copious amounts of tropical moisture, and you have a setup ripe for strong thunderstorms with torrential rain. What's more, northern Arizona is home to the Mogollon Rim, an area of high elevation that can provide the additional lift needed to trigger the development of thunderstorms that will often drift into the Phoenix area.
