(Fox 10) Heavy rain slowed the Phoenix area's morning commute and resulted in firefighters rescuing multiple motorists from vehicles trapped by street flooding from runoff.

The National Weather Service issued a flash flood warning for much of the metro area and said up to two inches of rain fell in some spots in about an hour Tuesday morning. 

Phoenix Fire Capt. Benjamin Santillan said firefighters from Phoenix and the Daisy Mountain Fire District on Phoenix's northern outskirts rescued at least six motorists in separate incidents.

Crews waded into swift water in order to rescue one woman from inside a van near 150th Avenue and Dynamite. She was lifted to safety as water continued to flow over the vehicle. 

In New River, a first responder landing on top of a home in order to rescue two people stuck inside. The rescue is still in progress. 

No injuries were reported.

Sandra Day O'Connor High School had to temporarily relocate 12 classrooms of students because of flooding from the storm.

"Due to the large amount of rain in a very short period of time on the morning of August 19th, 2014 the Sandra Day O'Connor High School experienced some water intrusion in to one of the classroom buildings. As a result, 12 classrooms have been temporarily relocated as the storm damage is remediated. Normal class schedules will continue while this takes place. The safety of students always remains a top priority for the Deer Valley Unified School District," stated Heidi Vega, DVUSD's Director, Communications and Community Engagement.

Flood waters were seen covering the roads near the Grand Avenue and Bethany Home Road intersection and Greenway Road underneath the I-17 overpass; the freeway itself was not affected.

A huge wave of water was seen flowing down Interstate 17 northbound near Dixileta. It was furiously traveling toward Happy Valley Road. 

"This is going to be a massive undertaking by ADOT engineers to try to figure out what to do with this water," said DPS spokesman Bart Graves. "My sense is we're going shut down the northbound lanes at some point and hope it doesn't cross into the southbound lanes of I-17."

If you were planning on taking I-17 to Las Vegas, an alternate route is to take Loop 303 to Lake Pleasant. Further north, a mudslide shut down the northbound lanes of I-17 from Loop 303 to Table Mesa Road. The left lane has reopened, but the right lanes remained closed.  

A small trailer park in Black Canyon City is being in the northern outskirts of the Phoenix metropolitan area.

The Yavapai County Sheriff's Office says the 15-20 residents of the River's Edge Trailer Park are being evacuated and are being offered shelter by the Red Cross at Cannon Elementary School in Black Canyon City.

Sheriff's spokesman Dwight D'Evelyn says there's been minimal flooding damage to the park so far but that authorities want to get residents to a safe location because flooding has damaged roads in the vicinity.

Beware of flooding in creeks, washes and other drainage areas due to heavy rainfall.

Two residents and three dogs were rescued from a flooded house north of Phoenix after more than four inches of rain pummeled some areas of the state.

Dramatic television footage showed the residents in New River, about 30 miles north of Phoenix, waving a white towel out of a window as floodwaters raged around the house. A helicopter hovered above and lowered a rescuer down onto the roof.

Phoenix Fire Capt. Benjamin Santillan says two women and three dogs were pulled to safety with no injuries.

A separate rescue played out as water submerged a minivan and authorities pulled a woman from the vehicle.

Several inches of rain fell on the Phoenix area Tuesday morning, closing a portion of the major north-south freeway in Arizona and delaying flights.
