The surprising rain occurrence has caused several Friday mishaps.
A man driving a Ford Ranger hit a large patch of water and lost control of his vehicle, flipped over and hit a man waiting for a bus.
The odd series of events took place in the 5600 block of Babcock Road near Huebner.
The driver is OK, but the man waiting for the bus was transported to the hospital.
Witnesses say speed was not a factor in the accident.
Meanwhile a high-water rescue took place in the 13200 block of George Road where a woman was trapped in her vehicle at a low water crossing.
She was uninjured.
