The desert Southwest is poised to get a second soaking after monsoon rains rollicked the region, stranding drivers, flooding streets and prompting water rescues.

Meteorologists say there is possibility of flooding Wednesday in six states — Arizona, New Mexico, Colorado, Nevada, Utah and California.

In Phoenix, a storm late Tuesday dropped 2 inches of rain in an hour in some spots, while bypassing other suburbs.

The weather wreaked havoc on evening commutes as flooding closed an underpass of a major freeway.

The rains bring some relief to crews fighting wildfires, but also the potential for mudslides in areas blackened by flames.

Heavy rain is typical during monsoon season, when wind patterns shift every summer and draw moisture from the Pacific Ocean to the Southwest.
