According to gage data from the Maricopa County Flood Control Network, some of the heaviest rain in the greater Phoenix area occurred in east Mesa during the early morning hours, with measured rainfall totals exceeding 5 inches within a 6 hour period. The heavy rain led to significant flash flooding across Mesa during the morning hours resulting in damage to area homes and businesses as well as severe disruption of morning traffic. One area that was especially hit hard was the Emerald Acres neighborhood located just north of US 60, and bounded by Stapley Drive and Harris. Due to various man-caused factors, the flash flooding was followed by areal flooding which persisted in the neighborhood for about 2 days and resulted in millions of dollars in damages to over 200 homes. Widespread and intense showers...along with embedded thunderstorms...developed across much of the greater Phoenix metropolitan area, including southeastern valley communities such as Chandler and Tempe, during the early morning hours. Rainfall rates were well in excess of 2 inches per hour, briefly reaching to near 6 inches per hour, and the heavy rain led to significant urban as well as flash flooding. At about 0300MST a trained weather spotter reported serious flooding and hydroplaning occurring at the intersection of the Loop 101 northbound and Guadalupe Road in Tempe. Three of the lanes were flooded and impassable. Widespread and intense showers and embedded thunderstorms developed across the central portion of the greater Phoenix area during the early morning hours on September 8th, and they affected the community of Ahwatukee. Rainfall rates with the heavier storms exceeded 2 inches per hour at times and led to significant flooding of streams, washes and roads in the area, and the flooding seriously impacted the Mountain Park Community Church located at 24th Street and Pecos Road. A wash that runs behind the church crested during the morning's heavy rainfall and sent water cascading into the church. The water rose above the chairs in the auditorium, actually filling up the entire auditorium. The flooding made for a massive cleanup, and close to 75 volunteers rallied during the afternoon to clean up the mud and debris. Widespread showers and embedded thunderstorms produced very heavy rainfall across the central portions of the greater Phoenix area during the early morning hours on September 8th. Rainfall rates were well in excess of 2 inches per hours at times, and the heavy rain caused major flash flooding on Interstate 10. At 0400MST the Arizona Department of Transportation reported that Interstate 10 was closed at 43rd Avenue, as the intense rain caused a lake to form several feet deep across the freeway. Since it was pitch black at the time, motorists unwittingly drove into the lake and became stalled; at least 2 dozen motorists became stranded in water which came up to the top of their hoods. The freeway was soon closed between 35th and 67th Avenues; after the water began receding at 0930MST, ADOT crews worked feverishly to clean up the road. Westbound Interstate 10 partially opened by 1400MST, the eastbound lanes were closed through the early evening hours. Widespread showers and embedded thunderstorms produced very heavy rainfall in Mesa during the morning hours on September 8th; peak rain rates were well in excess of 2 inches per hour and many locations received between 3 and 5 inches of rain with this event. The heavy rain led to significant urban flooding across Mesa, and one area that was especially hit hard was the Emerald Acres neighborhood located just north of US 60, and bounded by Stapley Drive and Harris. Water flowing towards the south ran up against a large berm protecting the Superstition freeway and had nowhere to go. A flood control canal bordering the freeway as well as several water retention basins were in place to protect against flooding; due to the excessive volume of runoff they were overwhelmed and as a result the neighborhood became flooded with one to three feet of water. Approximately 200 homes suffered significant flood damage and many residents had to be evacuated. Many of the homes suffered ruined flooring as well as damaged drywall that needed to be replaced. Crews started pumping water out of the area with large machines on Tuesday, September 9th and by early morning Wednesday, most of the water was removed from the streets in the Harris/Stapley neighborhood. It was estimated that water would not be completely removed for a week. Widespread showers and embedded thunderstorms developed across the greater Phoenix metropolitan area during the early morning hours, and they produced intense rainfall which affected the northern communities such as Carefree, Cave Creek and Anthem. Peak rainfall rates exceeded 3 inches per hour at times, and many trained weather spotters across the area measured between 2 and 5 inches of rain during the morning hours. At 0734MST, a trained spotter 5 miles southeast of Anthem reported flash flooding and indicated that the road was closed and impassable at the intersection of Cloud and Central.

Storms initially developed over the high terrain of northern and eastern Arizona as well as near the Table Top mesa area south of Phoenix. High DCAPE promoted strong thunderstorm downbursts. The downbursts generated outflows that progressed into the greater Phoenix metro area and led to the development of additional scattered thunderstorm. The thunderstorms in the metro area produced damaging winds that led to numerous downed trees, downed power poles, and other property damage. The storms were also nearly stationary, under weak steering flow, and produced very heavy rainfall with rain rates around 1.5-2.0 inches per hour and briefly higher in the strongest storms. This led to considerable flash flooding around Phoenix with several road closure and significant flow in major washes. Even after the strongest storms in Phoenix subsided in the late evening of the 22nd, areas of moderate to heavy rain continued from northeast to southwest through the night and through mid-afternoon on the 23rd. The continued rain through the 23rd was aided by a strengthening diffluent flow regime between the monsoon high to the north and a retrograding upper low moving west through New Mexico. Additional significant flash flooding was observed on the 23rd, mostly in the foothills north of the Phoenix metro, with many road closures, flowing washes and creeks, and some water rescues.

With abundant moisture and high CAPE values in place, the environment was favorable for the development of strong to severe thunderstorms. Thunderstorms initially developed over the high terrain of eastern Arizona before racing toward the west/southwest into the lower deserts of south-central Arizona as a line of strong to severe thunderstorms. The main impacts associated with these thunderstorms occurred as they moved into the Phoenix metro, producing widespread damaging wind gusts. Multiple observations recorded wind gusts in excess of 60 mph with a few approaching 80 mph. Recently implemented damage threat categories for Severe Thunderstorm Warnings were put to the test with one destructive Severe Thunderstorm Warning being issued for 80 mph wind gusts for much of Phoenix. There were numerous reports of downed trees across the Valley as a result of the severe wind gusts. The strong winds also led to several reports of dense blowing dust in dust prone areas. Additionally, thunderstorms produced locally heavy rainfall that led to several instances of flash flooding. No injuries were reported.

Moderate to high instability and high moisture content supported scattered strong thunderstorms. With deep south to southwest upslope flow, storms favored the foothills and mountainous areas of Maricopa and Gila counties. Most storms were producing at least 1 to 2 inch per hour rain rates, with several storms producing 2 to 3 inch rates and at times higher. Back-building and training of storms over the same areas resulted in significant to catastrophic flash flooding. A few burn scars experienced flash flooding, including the recent Telegraph burn area which had catastrophic flooding of the Russell Gulch drainage. There were also 2 fatalities on this day with off-roaders recreating near Camp Creek in northeast Maricopa County. The strong to severe storms also produced damaging winds from microbursts and small hail over lower desert locations.

Increased east-northeast steering flow resulted in relatively high shear values for the monsoon (Sfc-6km shear around 25-30 kts) and very steep mid-level lapse rate (8-8.5 C/km) supported the organized multicellular storm mode with robust updrafts. Inversely, very high DCAPE values, up to 1500-1800 J/kg, supported very strong downbursts. Moisture levels were also above normal which, in combination with the strong updrafts, supported high rainfall rates (1.5-2 inches per hour average). There were a few multicell clusters that moved through Southern Arizona. One through the southeast parts of the greater Phoenix area, another that developed in Yavapai County before descending southwest along US-60 in Maricopa and La Paz Counties, and a third that developed off the Kofa Wilderness terrain south of Quartzsite before being caught by the cluster descending along US-60.

PWATs rose to 2, which was near record for the period, and with the increased moisture instability values also rose with MLCAPE values in excess of 2,000 J/KG. The forcing from the aforementioned low pressure helped to enhance the thunderstorm activity as it was moving from south to north.\nEvent Narrative: Ralston Road at the Vekol Wash low water crossing in Ak-Chin Village was flooded and was impassable for several hours. Peak floodwater height was measured at nearly 7 feet at around 1951 MST by the Pinal County Flood Control gauge at the crossing. Timing estimated based off when the water level first reached 1 feet deep. No damages or injuries were reported.", "The following events were reported: Thunderstorm Wind. These occurred near station USW00023183, approximately 25.0096 km away, between 2022-09-23 17:47:00 and 2022-09-23 17:47:00. The events included records with measured wind gusts of 55.0 mph.Thankfully, no injuries or fatalities were reported. No significant property or crop damage was reported. \n\nEpisode Narrative: An abundance of moisture (PWAT 1.5+) and moderate to high instability (MLCAPE of 1000-2000 J/KG) led to the development of terrain and diurnally induced thunderstorm activity. Thunderstorms first began to develop across portions of southwestern Arizona during the early afternoon hours and thereafter, additional storm development occurred across the higher terrain east of Phoenix. Outflow from storms, particularly across the higher terrain east of Phoenix led to the development of more storms across portions of the Phoenix metro, particularly in the area between Chandler and Queen Creek.\nEvent Narrative: A 63 mph wind gust was measured at the Chandler Municipal Airport.", "The following events were reported: Hail. These occurred near station USW00023183, approximately 47.7744 km away, between 2022-10-03 17:37:00 and 2022-10-03 17:37:00. The events included records with hailstones measuring 0.88 inches.Thankfully, no injuries or fatalities were reported. No significant property or crop damage was reported. \n\nEpisode Narrative: A shortwave trough approaching the area from the west along with moderate levels of instability (MLCAPE 1000 J/KG) and unseasonably high moisture content above the 90th percentile (PWAT 1-1.3) resulted in a favorable environment for the development of strong thunderstorms. A complex of strong thunderstorm activity developed north and west of Phoenix during the early to mid afternoon hours. This thunderstorm complex resulted in a strong outflow boundary, which surged southward across the Phoenix metro area between 1530MST and 1630MST. This strong outflow boundary produced areas of dense blowing dust as well as damaging winds, with widespread wind damage observed across several portions of the Phoenix area. Winds across the area remained elevated for approximately two hours, making the timing of the damages reported unclear. Other more isolated thunderstorm activity developed across the higher terrain east of Phoenix during the mid to late afternoon hours, with one thunderstorm in particular affecting the Gold Canyon area, resulting in flash flooding.\nEvent Narrative: Hail of the size of nickels was reported along North 183rd Avenue in Surprise. Timing estimated from radar. No damages or injuries were reported.", "The following events were reported: Flash Flood, Hail, Lightning, Thunderstorm Wind, Tornado.

The events included records with hailstones measuring 23.5 inches.The events resulted in 1 injuries and 0 fatalities. The events caused property damage valued at 33000.0 and crop damage of 0.0. \n\nEpisode Narrative: A slow moving low pressure system brought several rounds of showers and thunderstorms across portions of south-central and southwestern Arizona throughout the day on the 15th. Strong southerly flow out ahead of the low pressure system brought in highly anomalous moisture content across the southern half of Arizona, with PWATs surging to 1.1-1.4, which are near record values for mid-October. Along with the highly anomalous moisture values, moderate to high instability values were also present with MLCAPE rising to 1000-1500 J/KG. Bulk shear values between 25-35 kts were also present. The combination of the highly anomalous moisture content, instability, and shear along with the strong dynamic forcing to the east and north of the low pressure system was a recipe for these showers and thunderstorms to produce flash flooding as well as severe wind gusts and hail. The greatest flash flood impact occurred along portions of western Maricopa County in the area from Buckeye to Tonopah, The greatest damaging wind impact occurred in the Tonopah area, where two rounds of severe thunderstorms, one hour apart, impacted causing widespread power outages due to downed power poles, destroyed two mobile homes, damaged dairy farm structures, and resulted livestock losses. Severe hail was also reported with a storm that moved into the Mesa to Scottsdale area during the overnight period. ||As the area of low pressure moved eastward on the 16th, lingering moisture resulted in the development of more showers and thunderstorms, mainly concentrated across the higher terrain areas east of Phoenix. One isolated storm in particular developed on a open field near Sun Lakes, resulting in the development of a short-lived landspout during the mid-afternoon hours with no damages reported.

Above normal moisture was present with PWATs in excess of 1.5 across most of central and southwestern AZ. The available moisture in combination with the daytime heating led to the development of moderate instability with MLCAPE in excess of 1000 J/KG. The strong westerly flow aloft led to strong vertical shear with 0-6 KM shear values ranging between 30-40 knots. All of these factors led to a very favorable environment for the development of strong to severe thunderstorms across portions of south-central AZ. Scattered thunderstorms started to develop by the early afternoon hours of the 12th with multiple rounds continuing into the evening hours. One severe thunderstorm in particular developed near the Buckeye area, became supercellular, and tracked generally eastward affecting areas such as Goodyear, Glendale, Phoenix, Scottsdale, Mesa and Apache Junction, causing extensive straight-line wind damage along its path. Additional thunderstorms developed just east of the Phoenix metro area during the overnight and early morning hours of the 13th, with the main impact being isolated flash flooding.

Additional thunderstorms developed just east of the Phoenix metro area during the overnight and early morning hours of the 13th, with the main impact being isolated flash flooding. The synoptic pattern was characterized by strong westerly flow aloft situated across most of the Desert Southwest with embedded shortwave energy providing the main source for rising motion. Above normal moisture was present with PWATs in excess of 1.5 across most of central and southwestern AZ. The available moisture in combination with the daytime heating led to the development of moderate instability with MLCAPE in excess of 1000 J/KG. The strong westerly flow aloft led to strong vertical shear with 0-6 KM shear values ranging between 30-40 knots. All of these factors led to a very favorable environment for the development of strong to severe thunderstorms across portions of south-central AZ.

Numerous reports of considerable damage at Falcon Field Airport from a severe microburst. Around 25 airplanes, mostly Cessna small aircraft, were damaged or destroyed, with some flipped over. One aviation flight school lost one third of their fleet, but it is unknown how many aircraft that amounts to. A few pilots reported that even planes with proper tie-downs broke free, with wind eyelets snapping and chains breaking as the planes likely tried to become airborne. Numerous hangars suffered significant damage, with around 90 hangar doors damaged or destroyed. Two World War II era hangars were damaged, with one losing its roof. Another hangar had an entire side wall shorn off. There were several downed trees around the airport, as well as damages to some other airport infrastructure and property, like fencing. A news report nearly three months later stated repairs are still being done and the total damages at the airport is around $7.2 million. An ASOS at Falcon Field Airport did not measure peak wind gusts from this storm due to a loss of power at the airport. Thus, based on damages, winds were estimated around 90 mph. No injuries were reported. Video showed hailstones up to one inch in diameter in the Mountain Bridge Neighbor in Mesa located just east of Loop 202. No damages or injuries were reported.
