Frequent future Arizona floods likely, 700 years of data shows
Snowstorms froze the High Country while floods drenched the Valley. Arizona is leaving behind a very wet winter in 2023, with numerous parts of the state reporting above-average rain and snow over the past few months, according to the National Weather Service (NWS). This year landed in the top five winters for record snowfall for Flagstaff, Willaims and the Grand Canyon. Arizona’s Verde River is also at a record-setting amount of snow water equivalent this year. The numbers are still dwarfed by Arizona’s wettest year on record from July 1992 to June 1993. Both Phoenix and Flagstaff saw around 10 more inches of water precipitation accumulation than we’ve seen this year, according to NWS data.
