Phoenix saw its second-wettest day of 2025 but is still experiencing its 10th-driest start to any year, while Tucson is experiencing its third-driest year to date.
Both cities' records go back to 1895.
"The Southwest? Guess what. Monsoon is in full swing," FOX Weather Meteorologist Britta Merwin said. "A little bit of a slow onset, but we’re feeling it. And it has been bone dry in Arizona."
The FOX Forecast Center said a ridge of high pressure shifted toward the Four Corners region over the weekend, and a surge of monsoonal moisture has been pushing through the area.
The rainfall is beneficial as all of Arizona is in a drought.

More precipitation and thunderstorms are on the way, and fears are growing that flash flooding could occur due to intense rainfall rates of 1-1.5 inches an hour.
Flood-prone areas, including in canyons and burn-scar areas, should remain alert to potential flooding.
In fact, NOAA’s Weather Prediction Center (WPC) has placed portions of southern Arizona in a Level 2 out of 4 flash flood risk on Tuesday.
