Flash Flood Warnings issued across northern Arizona

Flash flood warnings were issued for parts of Coconino County as monsoon storms continue to bring heavy rain and hail to northern Arizona.

"Life-threatening" flash flooding is expected to hit areas near Flagstaff, including Timberline, Pine Mountain Estates, Hutchinson Acres, Macann Estates, Government Tank Wash, and Little Elden Springs Horse Camp.

On July 15, Coconino County officials confirm they have made a request to the Arizona Department of Emergency and Military Affairs for assistance from the National Guard in filling sandbags.

"ADEMA will now review the request," read a portion of the brief statement. "We have also received assistance from the state with sandbag production through the Arizona Department of Corrections. Arizona Conservation Corps crews have also assisted with sandbag production and placement for those that are elderly or disabled."

Meanwhile, Yavapai County has reported gusty winds of up to 40 miles per hour and half-inch sized hail. Flood warnings have been issued for Prescott, Jerome, Cottonwood, Cherry and Mingus Mountain.

Road closures

US 89 is closed in both directions near Flagstaff due to flooding at milepost 424, near Johnson Ranch Road. There is no estimated time to reopen.

Rain/flood safety tips

The American Red Cross' tips for heavy rain situations and flood safety:

  • Turn around don’t drown! If you must drive and you encounter a flooded roadway, turn around and go another way.
  • If you are caught on a flooded road and waters are rising rapidly around you, get out of the car quickly and move to higher ground.
  • Tune in to your local radio, NOAA radio, or news channels for the latest updates.
  • If your neighborhood is prone to flooding, be prepared to evacuate quickly.
  • Follow evacuation orders and do not attempt to return until officials say it is safe.
  • If power lines are down, do not step in puddles or standing water.
  • If power is out, use a flashlight. Do not use any open flame as alternate lighting.

Be prepared and stay safe during the monsoon

"Most Valley residents know how quickly and furiously storms can move in and out, bringing strong winds, dust, rain, and flash flooding. These storms can cause interruptions in services, such as water, power, and gas," stated Captain Ashley Losch of the Glendale Fire Department.

GFD reminds residents of ways they can be prepared and stay safe:

  • Have flashlights with extra batteries on hand.
  • Have food that can be prepared without the need for cooking or refrigeration.
  • Have at least one gallon of clean water for each person in the household.
  • Have backup power for anyone requiring power for a medical device.
  • Have backup power for cell phones that do not require charging.
  • Have a first aid kit ready and accessible.
  • Never drive into areas with flowing water; it takes less than 10 inches to wash a car away.
  • Avoid flooded areas, such as washes.
  • If waters are rising, seek higher ground.
  • Do not approach downed power lines, the ground can be energized for up to 200 feet.
  • Keep pets indoors during storms.
