The downed poles and lines also knocked over street signs and street lamps, disrupted traffic, and caused a power outage for the area that took more than a day to be restored. Additionally, several large trees were uprooted or snapped in and around Cortez Park at 35th Ave and Dunlap Ave and a metal carport reportedly blew more than a block away near 35th Ave and Peoria Ave. Wind gusts were estimated around 55-65 mph. Timing estimated from radar. No injuries were reported. |
| July 2008 | Flash Flood | Sunnyslope | $200,000 | Streets and highways became flooded and some road closures were reported after rainfall rates exceeded 2 inches per hour in the heaviest storms. One spotter in East Mesa had a total of 2.50 inches. |
| August 2015 | Thunderstorm Wind | Sunnyslope | $100,000 | Thunderstorms raked the north central portion of the greater Phoenix metropolitan area during the afternoon hours on August 27th; due to a favorable combination of enhanced instability and wind fields aloft, the stronger storms were able to generate strong damaging microburst winds. Some of the areas that were especially hard hit were northern communities such as north Phoenix and North Mountain Park. According to local broadcast media reports, at 1600MST gusty winds estimated to be as high as 80 mph produced significant structural damage to a mobile home park located about 1 mile southeast of the Metro Center Mall. The damage was just east of Interstate 17 and north of West Dunlap Avenue. No injuries were reported. |
| August 2008 | Thunderstorm Wind | Sunnyslope | $100,000 | Trees and power lines down. |
| November 2019 | Tornado (EF0) | Sunnyslope | $40,000 | A powerful Pacific upper level low and associated cold front pushed east across the central and northern portions of the greater Phoenix metropolitan area during the early morning hours on November 29th. Due to elevated levels of wind shear and instability, the front spawned several tornadoes in the Phoenix area, including one that tracked through portions of North Phoenix and Deer Valley. The tornado moved to the northeast, across Lookout Mountain, and ended near the intersection of Loop 101 and Highway 51. The tornado, which was spotted by both the public and members of local broadcast media, touched down at about 0349MST and lifted back in the sky at 0359MST. The path length was nearly 10 miles. There were numerous reports of damage, some reported via social media. Broadcast media reported several trees downed along Thunderbird Road between 7th Avenue and 3rd Street. Media also reported several trees downed about 5 miles southeast of Deer Valley, and a carport was also destroyed. Additionally, at 0355MST the public reported that a carport was blown over onto some cars near the intersection of Bell Road and 15th Street. Fortunately there were no reports of injuries or fatalities due to the tornado. |
| July 2021 | Thunderstorm Wind | Sunnyslope | $25,000 | Broadcast report from local media showed a carport ripped away from a residence near Sahuaro Drive and 37th Drive due to strong winds in a severe warned thunderstorm. The carport flew into an alley behind the residence, knocking over a cinderblock wall and shattering the window of a residence on the other side of the alley. Winds were estimated around 55-65 mph and timing was estimated from radar. No injuries reported. |
| August 2010 | Thunderstorm Wind | Sunnyslope | $25,000 | A trained spotter reported that power poles were blown down at 19th Avenue and Dunlap. The poles were downed by thunderstorm microburst winds estimated to be in excess of 50 kt. |
| October 2018 | Flood | Sunnyslope | $20,000 | Copious amounts of tropical moisture spread north and into the greater Phoenix area during the morning hours on October 2nd; the moisture was associated with former hurricane Rosa. The moisture resulted in the development of widespread moderate to heavy showers which persisted into the afternoon hours, and affected the central portion of the Phoenix area including the community of Glendale. Heavy rains led to episodes of flash flooding and flooding, causing many road closures and resulting in some street damage. According to a report from a local newspaper, at 1435MST a sink hole developed at the intersection of 35th Avenue and Cactus Roads, about 5 miles northeast of Glendale. The sinkhole was caused by flash flooding that occurred earlier in the day and resulted in the intersection becoming closed. A Flood Warning had been issued earlier in the morning for the area, but the warning expired shortly before the sinkhole was reported by the paper. |
| August 2021 | Thunderstorm Wind | Sunnyslope | $17,000 | A portion of the roof of an apartment complex near 7th Avenue and Hatcher Road was torn of in strong winds and landed on an unoccupied parked car, causing damage.

According to a trained weather spotter, at 1020 pm near 25th Avenue and West Happy Valley Road, 25 foot long tree branches were blown down. Winds estimated to be at least 50 mph were strong enough to shake vehicles in the area.

Some of the stronger storms, with peak rain rates in excess of one inch per hour, affected communities such as Deer Valley and north Phoenix. The locally heavy rain was sufficient to produce an episode of flash flooding. According to local broadcast media, at 2215MST flash flooding caused the road to be closed on West Thunderbird Road eastbound near north 26th Avenue. This was about 4 miles south of Deer Valley. The flooding resulted in multiple vehicles becoming stranded in the flood waters. Fortunately there were no injuries reported. A Flash Flood Warning had been issued for the area at 2215MST. |
| October 2018 | Flash Flood | Sunnyslope | $2,000 | Copious amounts of deep tropical moisture spread into the greater Phoenix area during the morning hours on October 2nd; the moisture was associated with former hurricane Rosa. The deep moisture resulted in widespread moderate to heavy showers. Many locations picked up 2 to 3 inches of rain during this event with much of the rain occurring in the morning. The heavy rain led to numerous episodes of flash flooding including many road closures across the central and northern portion of the Phoenix area. According to the Arizona Department of Highways, at 0732MST flash flooding resulted in a road closure at the intersection of Interstate I-17 and Peoria Avenue, about 5 miles northeast of Glendale.

In addition to bringing strong wind, the storms produced very heavy rain with rain rates in excess of 2 inches per hour. The heavy rains affected North Mountain, and led to flash flooding along Interstate 17 about 1 mile north of the Metro Center Mall. According to a trained weather spotter, at about 1530MST, flash flooding caused 3 to 4 feet of water to accumulate under the underpass of Interstate 17, creating extremely hazardous conditions for motorists.
