A Tribal spokesperson for Hopi’s First Mesa Consolidated Villages says monsoon activity led to a rise in water levels at the Polacca Wash this week, with particularly high water Thursday night. Louella Furcap says rainfall in Pinon and Low Mountain led to high runoff. Two roads on Hopi remained closed last night, according to KUYI Hopi Radio, including part of Route 60. The Hopi Emergency Relief Fund is seeking volunteers to fill more sandbags at the Hopi Tribal Housing Authority. Information is at 928-299-1992.  

This weekend’s monsoon activity led to further flooding in the area of the Museum Fire Burn Scar in Flagstaff. Other parts of the city flooded, as well, including the downtown area and parts of Northern Arizona University.

NAU issued temporary road closures Saturday night due to flood waters. The National Weather Service predicts a 55% chance of rain and thunderstorms today in Flagstaff, with stronger storms expected to return later in the week.



The Navajo County Board of Supervisors has declared a State of Emergency due to localized flooding. The county has activated an Emergency Operations Center and will be sending updates through social media platforms, primarily the Navajo County Emergency Management and Preparedness page, https://www.facebook.com/NavajoCountyEM.

A strong monsoon pattern is expected to impact much of the state through at least late Saturday night. County officials across central and northern Arizona advise people living below burn scars and in other flood prone areas to be prepared.

Streets in east Flagstaff filled with mud and debris this week as flash floods poured down from the Museum Fire scar. The two-year-old burn scar is a study site for scientists at Northern Arizona University, who want to know how forests will recover from wildfires in a warmer, drier climate. Just before the flooding, KNAU’s Melissa Sevigny took a tour of the spot to learn about the experiment.
