The US National Weather Service issued warnings Thursday for flash floods in Arizona, with heavy rains and lightning expected to continue through Saturday night.

Flash-flood warnings were issued for several communities in Maricopa County and also in Roosevelt in neighboring Gila County.

In Scottsdale, more than 2 inches of rain were recorded in an hour, ABC15 reported. Cars were also seen being washed away in Scottsdale, AZ Family reported.

More than 5 inches of rain were expected in some areas, per CNN. "Looking at just the southeast Arizona a lot of the valleys are going to see rainfall amounts most likely between 1 to 2 inches, maybe higher in other spots," the National Weather Service Tucson meteorologist Rob Howlett told the news network.

The Twitter user Fan of Arizona posted a video of water gushing down a hill and forming a pool at the bottom.

The rains follow an extended period of drought in Arizona since late last year, according to data from the Arizona Department of Water Resources.
