Hurricane Rosa’s Legacy: 3 inches of Rain in North Phoenix

For 15 years, In&Out Magazine has been the definitive source of “Everything that’s going on” in and out of the community. We thank you, our readers, as well as the businesses that support the magazine through advertising, for that opportunity. But with little going on, and many businesses suspending or canceling their ads during the Covid-19 crisis, we are suspending publication of the magazine and web sites for the month of May.

At one time a Category 4 hurricane in the Pacific, with top winds near 145 mph, Rosa’s comparatively calm but persistent remnants dumped 3 inches of rain in New River and near the Arroyo Grande neighborhood on the far west side of Anthem. The storm smashed a daily rainfall record in Phoenix, with 2.36 inches falling at Sky Harbor Airport on Oct. 2—the previous record for that date was 0.60 inches in 1981.

Given those statistics, we’ve added Rosa to our list of Top 10 Hurricanes That Have Affected Phoenix. Below are are some key facts and figures and some memorable photos and videos. First the totals:

How Much Is That?

In an average year, Deer Valley Airport gets 10.76 inches of rain, with 0.76 inches of it typically falling in October. Anthem and New River, being near the mountains, tend to get more (Deer Valley Airport is at 1,478 feet of elevation; Anthem ranges from 1,760 to 2,428 feet). But because the history at these stations doesn’t go back very many years, the National Weather Service does not announce records for the area.

So here’s how the storm shook out at Sky Harbor Airport, the Valley’s official recording station:

  • The Oct. 2, 2018 total at Sky Harbor (2.36 inches) was 8th most rain measured on any day since 1895 (the record: 3.3 inches on Sept. 8, 2014, as the remains of Hurricane Norbert rolled through).
  • Total rain for the first two days of October 2018 was 2.68 inches, making it already the 3rd wettest October on record (the wettest October: 4.4 inches in 1972).

Other big numbers: A whopping 7.24 inches landed in an official rain gauge near Crown King, northeast of Phoenix. Two gauges south of Shea Boulevard between Tatum Boulevard and Scottsdale Road each recorded 4.02 inches.

Big and Slow

Rosa’s impact was related in large part to its duration.

Rosa’s northernmost clouds were over Arizona by mid-day Sunday, Sept. 30, while the center of the storm was well out to sea.

How important was Rosa to our annual rainfall accumulation? Sky Harbor typically gets about 8.3 inches of rain a year, with a good chunk of that coming during monsoon. As of 4 p.m. Tuesday, Oct. 2 at Sky Harbor:
