The Coconino County Flood Control District (FCD) and City of Flagstaff are actively involved in cleanup operations following monsoon storms that dropped in excess of 2 inches of rain on the Museum Fire burn scar. Downstream flooding has been reported in Mt. Elden Estates and in Flagstaff from Linda Vista to Route 66.
More than 0.75 inches of rain fell in 15 minutes over the Museum Fire burn scar, which triggered an Emergency Notification Alert to be issued to the entire Museum Flood Area. This area includes Mt. Elden Estates, Paradise, Grandview, and the Sunnyside area. The National Weather Service issued a Flash Flood Warning for the Museum Flood Area, which was in effect until 4:30 p.m. A Flood Advisory remains in effect until 7:30 p.m.
Flows in the channel overtopped the roadway at Linda Vista Drive and Cedar Ave. Street crews closed this section of Linda Vista and Cedar Ave. Fast-moving floodwaters and debris in flows approximately one foot deep were reported in the Sunnyside area running curb-to-curb on Main Street. Streets impacted due to flooding include Linda Vista, Main, Rose, Grandview, 4th Street, and Route 66.
The City and County Public Works crews are in the Museum Flood Area beginning to clear roads. Motorists are asked to avoid the flood area to allow crews to restore access and services to floodaffected areas.
Monsoonal activity is expected throughout this week. Risks both from typical storms and, as the season progresses, from smaller-sized rain events falling over saturated ground, can exponentially increase runoff. Officials are asking residents in flood-affected areas to take the following steps and to help ensure
- Never let children play in washes even if the washes are dry!
- Shelter in place or seek high ground
- Avoid Floodwaters: Keep your family and pets away from floodwater. Standing water hides many dangers including toxins, chemicals, and sharp debris. Do not attempt to cross flowing water. The current in just six inches of water can sweep you off your feet.
- Avoid Impacted Areas: Please do not visit flood-impacted areas. In addition to being dangerous, your presence may hamper emergency operations, which include utility work to repair downed powerlines.
- Heed Road Closed and Cautionary Signs: Road closure and other cautionary signs are put in place for your safety. Pay attention to them!
- Call 911 to report a flooding emergency.
- Secure Items: Do not leave trash cans, trash, or debris in any area subject to flooding. Items will float in floodwaters and clog storm drains and stream channels.
