Rain sweeps into Phoenix area, will stay for couple days

PHOENIX — Moderate rain was splashing down on metro Phoenix early Monday, but forecasts called for bigger, heavier cloudbursts by nightfall.

The rain from a weakening Tropical Storm Rosa still has enough power for the National Weather Service in Phoenix to issue flash flood advisories in some parts of the area.

About an inch of precipitation was expected in the Valley during the day hours but by evening 1½ inches more would come down. Normally dry washes could fill and spill over.

Weather watchers predicted a high of 82 degrees.

“Looks like we’re done with the hundreds,” weather service meteorologist Mark O’Malley said of the temperatures.

Rainfall at @PHXSkyHarbor – our official rain gauge – is now up to 0.36" since Sunday.

O’Malley said cloud cover would linger into Tuesday. Moderate rain could last until midweek.

Northern Arizona could get up to four inches of rain.

Closer to Phoenix, areas with slightly higher elevations, such as Cave Creek and Carefree could get as much as three inches of rain as Rosa moved out of Arizona.

Rosa dropped from hurricane to tropical storm status Sunday, coincidentally, the last day of Arizona’s monsoon season.

At its peak, Rosa had sustained winds of 65 mph while making its way toward Mexico’s Baja California.
