The thunderstorm moved in quickly around 4:30 p.m. dropping temperatures from 105 degrees down to around 78.
According to the National Weather Service in Salt Lake City the July 3rd storm brought 0.72 inches of precipitation.
As the clouds opened up, mother nature released hail in the north part of the city and large raindrops in the south.
Flash flooding carried heavy streams of red dirt and debris from hillsides, dumping the remains onto lower lying streets. It was a major gully washer on Bluff street in St. George as travelers were forced to drive through water up to three inches deep or more. It was reported that one accident was related to that storm.
Clean-up crews could still be seen cleaning up debris and sweeping the streets around 7:00 p.m.
The moisture will not only cool temperatures down but also help dampen any potential fires over the 4th of July.
