Monsoon Moisture Brings Pockets of Heavy Rain to the West
The last few weeks have brought monsoonal moisture to much of the Four Corners region. Colorado, New Mexico and Utah have also received a good amount of rain throughout the last week, especially for the Front Range of Colorado this weekend. Flood alerts are in place as more moisture may lead to flash flooding (especially around Burn Scars).
In fact, the month of July was the wettest on record for some.
Here are some July rainfall totals & rankings across SE AZ:
Picacho Peak: 6.76"/Wettest
Nogales 6N: 9.96"/2nd wettest
Sierra Vista: 6.48"/8th wettest
Ajo: 3.04"/10th wettest
Willcox: 4.61"/11th wettest
San Manuel: 4.07"/11th wettest
McNeal: 3.44"/34th wettest#azwx

For cities like Tucson, Arizona, July 2021 was the wettest month on record!
Flash flood watches are in place into western Colorado and the I-25 corridor of New Mexico as additional rainfall could prompt flash flooding, especially over recent burn scars.
As moisture migrates north, we will watch the flooding risk into portions of Montana, Oregon and Idaho through Monday.
However, that does not mean there won’t be any flood reports. Excessive Rain Outlooks are in place to start this week. Shaded areas could receive enough heavy rain to get brief flash flooding or debris flows. Never drive through flooded washes or water-covered roads!
We will likely see 1-2″ of rainfall in any thunderstorm that develops but in some locations, up to 3″ of rain will be possible.
We start to see monsoonal moisture migrate north, into Montana, Utah and Idaho. Showers will linger thanks to recycled moisture for New Mexico and Colorado. Some of these storms will be on the strong side.
