Severe storms and flash flooding are possible across Arizona midweek, with hail and heavy rain expected in much of the state.

Crews are clearing storm drains, staging barricades and positioning swift-water rescue teams.

Officials are coordinating with the National Weather Service on the storms’ timing and intensity.

A few inches of fast-moving water can knock an adult down, and less than two feet can float a car.

Officials repeat the rule: turn around, don’t drown. Never cross flooded washes or barricaded roads.

Residents should move cars under cover from hail, and hikers should reconsider desert outings.
