Monsoon Awareness Week is June 9-15 and Arizona State Parks and Trails wants you to remember best practices for outdoor recreation during monsoon season. The monsoon outlook by the National Weather Service currently predicts below-normal precipitation for the majority of Arizona, but it's still important to be prepared. All it takes is one storm to turn a fun outdoor adventure into an emergency situation.

Monsoon season begins June 15 and continues through September 30. Longtime residents of Arizona who know that storms may not begin until closer to July may find this start date rather odd. It helps to understand that monsoon season doesn’t simply refer to any single rainstorm. Rather, it refers to a seasonal shift in prevailing winds from a dry westerly flow to a moist southerly flow.

The resulting thunderstorms can bring serious safety hazards that outdoor enthusiasts should be aware of and prepared for when recreating. Adverse conditions can include dust storms, lightning that can spark wildfires, and flash floods with heavy debris flow.

Arizona’s arid climate receives a scanty amount of rainfall annually and is currently in a decades-long drought. Because of these factors, the soil cannot absorb the copious amount of precipitation that can fall in a short amount of time during a monsoon storm. The danger also escalates around areas that have been recently scarred by wildfire. Flash floods develop quickly and bring danger from rapidly flowing water and debris that can carry away people, vehicles, roads, and even structures.
