The city of Flagstaff has asked people to "shelter in place" as flash floods are expected in the Museum Fire Flood Area, Mt. Elden Estates, Grandview and Sunnyside neighborhoods Sunday.
The National Weather Service in Flagstaff issued a flash flood watch for portions of northern Arizona from noon Sunday through 5 a.m. Monday. Scattered to widespread thunderstorms are possible each afternoon through the middle of the week.
"Deep monsoon moisture will move across central AZ today," said the National Weather Service in Flagstaff in a tweet on Sunday. "Starting this afternoon, conditions will favor storms capable of producing heavy downpours of 2 to 3 inches."
Community members are asked to avoid flood prone area like creeks, drainages, and low water crossings.

The National Weather Service in Phoenix issued a severe thunderstorm warning for the cities of Peoria, Surprise, and Sun City in central Arizona that will last until 8 p.m. Sunday.
Residents should expect winds up to 60 miles per hour and nickel-sized hail, the weather service reports.
A special weather statement has also been issued for neighborhoods in Phoenix, Mesa and Glendale until 8 p.m. Sunday. Residents in those areas should expect 40 mile per hour winds.
"This evening's thunderstorm activity across the lower deserts of Arizona and Sonora is a testament to the ongoing moisture surge," said the National Weather Service in Flagstaff in a forecast discussion. "Increasing atmospheric moisture is enhancing the probability of widespread storms over the coming days for northern Arizona."
