Pima County hurricane guide¶

The Pima County Office of Emergency Management works to prevent loss of life and reduce property damage from disasters and helps cities and towns plan. The county's Be Flood Safe page says a 2017 analysis found Pima County was the eighth deadliest county in the nation for flood related deaths in the preceding 20 years. Flash flood damage tends to happen next to washes, arroyos, drainage channels, and street crossings.

What to know in Pima County¶

• Flash floods can occur many miles away from the storm that causes them. The county says to stop at a flooded roadway, never drive around a barricade, and not to walk through moving water, because six inches of moving water can make you fall and two feet of flowing water can sweep most vehicles downstream.
• The county says wildfires leave burned ground that cannot absorb water, so even light rain can cause flash floods or debris flows in and below burned areas, sometimes for several years. Flood alerts for burned watersheds need a MyAlerts sign up with the property address you are concerned about.
