PHOENIX (CBS5) -
Thunderstorms moved into south central Arizona Friday afternoon, and are expected to continue into Saturday.
Tucson fire officials said a storm passed through Tucson early Friday afternoon, with the south and central portions of the city being most impacted.
Tucson fire responded to Van Buskirk Elementary School which had heavy damage to the roof and at least five classrooms had water damage.
The storm also knocked down power lines. Officials said there were 18 people in the school at the time of the storm that had to be shuttled out because of downed power lines blocking the road in front of the school. There were no reported injuries.
ADOT said storms knocked down two power poles along State Route 88 near Lost Dutchman State Park, Friday afternoon. ADOT said crews are working to fix the poles.
CBS 5 News meteorologist Katie Baker said a few thunderstorms are in the Valley Pinpoint forecast for Saturday, before drying out on Sunday.
A severe thunderstorm warning was issued for east Maricopa County and northern Pinal County until 3:15 p.m.
In the Yavapai County community of Yarnell, crews placed 250 sandbags, to try to protect the memorial for the 19 fallen firefighters from flooding.
Some residents awoke Friday morning to the second day in a row of moisture, after isolated showers came down outside of the Valley.
But the rain didn't stop some people from being outside. Golfers could be seen playing in the rain near Litchfield and Palm Lane in Goodyear, on Friday morning.
The summer monsoon grew active Thursday afternoon, as residents from Flagstaff to Tucson were on alert for severe thunderstorms, hail and flooding.
Northwest Maricopa County was under a blowing dust advisory Thursday evening, which expired at 8 p.m.
Visibility ranged from a half-mile to a mile between Florence and Coolidge, during the mid-afternoon hours.
A flash flood warning covered extreme northeastern Maricopa County until 6:30 p.m. There was concern the rain would produce a significant flow in creeks and washes accompanied by mud, rocks and debris.
Flash flooding impacted low water crossings of forest roads and trails, including Forest Road 22 south of Highway 87, the Arizona Trail and Boulder Creek.
Central Pinal County had also been under a severe thunderstorm warning, which has now expired. There were indications the storms might be capable of producing dime-size hail, and damaging winds in excess of 60 mph.
There was a report of 0.83 inches of rain in 20 minutes near Miami, AZ, according to CBS 5 News chief meteorologist Chris Dunn.
Overall, up to 1 1/2 inches of rain fell in the affected area since 2 p.m.
A moist southeasterly flow is keeping rain chances alive.
Earlier in the day, morning commuters from the East Valley to central Phoenix encountered periods of lightning, and heavy rainfall.
Morning rain showers and thunderstorms, rolling thorough the Valley, pushed Phoenix above normal for the month and the year-to-date, said CBS 5 News chief meteorologist Chris Dunn.
"We've now measured 1.77 inches in Phoenix, this month of July, and we're over 4 inches of rain, since the first of January," Dunn said.
Flagstaff has also been seeing some of the monsoon madness, with storms hitting around noon.
Viewer-submitted photos showed significant flooding of roadways, and ground covered with hail. The Flagstaff Airport measured 1.34 inches of rain.
"This extremely moist air will continue to fuel more storms again Friday afternoon and evening, but I see a transition shaping up on Saturday, which will signal the beginning of a drying trend for much of Arizona, that will last well into next week," Dunn said.
