Almost each location recording rainfall totals across northern Arizona reported measurements far above what they might have usually skilled by this level in the summertime monsoon season, based on information from the National Weather Service.
“The next one to two weeks also seem like they’re going to be pretty active and wet in a lot of the area,” mentioned Justin Johndrow, a climate service meteorologist.
“So that’s just going to add on to these totals and maybe even get farther above normal over the next couple weeks,” he mentioned.
The departure from the normal rainfall varies broadly across northern Arizona, with many locations reporting between a half-inch to 2 inches extra rain than standard.
But the rainfall totals in just a few locations together with Bellemont, the Heber Ranger Station, Prescott’s Sundog Water Plant in addition to Sunset Crater and Walnut Canyon nationwide monuments recorded over 3 inches extra rainfall than they sometimes obtain at this level within the season.
The elevated recorded rainfall can probably be contributed to an early begin to the monsoon season along with moisture coming in from Northern California, mentioned Lee Born, workers meteorologist for KNAU and college at Northern Arizona University.
“It really aided in bringing deep Gulf of California moisture into Arizona,” Born mentioned. “Just where that high-pressure cell set up, it just really ramped up our moisture values across the state and we had a bunch of moisture to work with there for a couple of weeks.”
Only three places recorded rainfall lower than the realm’s typical common however these deviations had been minimal, involving lower than half an inch of rain.
But when wanting on the monsoon season as an entire, “It kind of all washes out in the end,” Born mentioned.
Because monsoon rains are so spotty, Born mentioned, by this level within the season it isn’t significantly stunning there’s such a variety in rainfall totals across Northern Arizona to this point.
For instance, Flagstaff airport has gotten solely 4 inches of rain whereas the east aspect of the town has gotten greater than 10 inches. That means the airport has recorded simply round half of the rain it usually does by this level within the year whereas different areas have seen a 200% enhance. As the season continues, storms will probably affect areas just like the airport that have not seen much rain but, bringing the rainfall totals nearer to normal.
“In the end, we’ll probably all be right around the same place,” Born mentioned. “So how great this last four weeks of rain has felt, we’re still half of normal just in 2022.”
With the elevated rainfall, some areas, significantly these round wildfire burn scars, have skilled excessive flash flooding repeatedly this summer season. Flagstaff residents on either side of the Pipeline Fire burn scar have been coping with weeks of sustained rains and flooding which have introduced with them sediment and particles from the scorched mountainside.
But this flooding, whereas extra excessive this year than most, can typically be a crucial hazard when coping with such extended drought circumstances, Johndrow mentioned.
“Obviously it’s unfortunate that it’s caused this flooding but to get runoff into the rivers and the reservoirs, it’s going to cause some flooding at times so there’s really no way to avoid that,” Johndrow mentioned.
“We really don’t get, especially in the summer, long gentle rains that fill reservoirs,” he mentioned. “It comes in large storms that have heavy runoff and flooding that helps fill those lakes.”
With weeks of monsoon season nonetheless forward, the town of Flagstaff met with group members Thursday night at City Hall to deal with the considerations of residents dwelling on the west aspect of the Pipeline burn scar and focus on short- and long-term mitigation efforts.
“The decision to hold a community meeting was made as we have seen multiple flood events to date, and we want to provide another opportunity to make sure residents have all of the information they need as we continue through monsoon season,” mentioned a spokesperson for the Flagstaff mayor’s office.
Storms are anticipated to proceed this weekend within the Flagstaff space. According to a climate service forecast Friday, remoted to scattered thunderstorms are potential Friday and Saturday with afternoon temperatures a bit hotter because of the decreased cloud cover and precipitation.
“Storm chances increase on Sunday with scattered to numerous thunderstorms expected each afternoon through the middle of next week,” the forecast acknowledged.
