The National Weather Service issued a Flood Advisory for eastern Pima County. It lasts until 4:30 p.m.

Between 1 and 2 inches of rain have fallen.

Locations include Tucson, Tanque Verde, Saguaro National Park East, Sabino Canyon Recreation Area, Catalina Foothills and Seven Falls.

1 p.m.

Another active Monsoon was expected Monday.

KGUN 9 Meteorologist Cuyler Diggs says the greatest chance of storms will be areas east of I-19 and east of I-10 between Tucson and Phoenix. Storms are forecast to move north from the east side of Tucson with flooding and blowing dust possible.

Some heavy rain is already underway around the east side of Tucson, with the National Weather Service already issuing a flood advisory around Tucson's east side and into the eastern section of the Santa Catalina Mountains. The advisory will remain in effect until 4:30 p.m.

As with previous storms this month, runoff from the Bighorn Fire burn scar area will continue to be a concern, with debris flows likely below areas of the mountains with heavy rainfall.

After Monday's storms, a smaller chance remains Tuesday before a warming trend hits southern Arizona with highs in the 100s the rest of the week, and a heat watch in effect for much of the state.
