PHOENIX — Storms hit areas of the Southwest again on Wednesday, but with less intensity than a day earlier when monsoon rains swamped the desert region, stranding drivers, flooding streets and prompting water rescues.

Forecasters warned of the potential of more flooding in six states — Arizona, New Mexico, Colorado, Nevada, Utah and California, particularly in washes and streams.

Rain fell in the Four Corners region but there were no reports of flooding or mudslides. More intense monsoon rain was expected in that area through Friday, according to the National Weather Service.

Flood watches in effect covered large swaths of desert and forests and cities such as Phoenix, Las Vegas, Tucson and Albuquerque.
