(CNN) -- As many as 4 inches of rain fell near Phoenix on Tuesday, sending flash floodwater through areas of Arizona already saturated from recent rains.
The smashing currents of water enveloped the base of one home, trapping at least one person inside. A rescue crew flew in by helicopter and was attempting to get anyone in the home to safety.
CNN affiliate KPHO reported that the rescue was one of several taking place.
The National Weather Service in Phoenix said a flash flood warning was in effect for central Maricopa County until 2:15 p.m.
The service tweeted at 1 p.m. that very heavy rain was about to fall in Scottsdale.
There was 3.98 inches of rain in New River, according to CNN affiliate KTVK.
