Rob Schumacher,

Another round of strong monsoon storms moved into the Phoenix area Wednesday evening, and the National Weather Service has issued significant weather advisories for Maricopa County. 

Strong thunderstorms bringing heavy rain to a wide swath of the Valley moved into the region from the north and east. 

Fountain Hills, where more than an inch of rain fell in several areas, and north Scottsdale were among the hardest-hit areas.

Scottsdale Fire Department officials responded to power lines blown onto seven cars due to the pole holding the lines snapping at Scottsdale and Deer Valley roads, trapping motorists in cars, fire officials said. Arizona Public Service crews responded and the lines were removed from the vehicles safely. Scottsdale Road was closed in the area late Wednesday.

In south Scottsdale, a downed power pole forced police to restrict traffic near Thomas and Hayden roads. Scottsdale police said numerous other streets were impacted by downed trees, flooding or other issues, including Pima Road between Princess Drive and Legacy Boulevard, which was closed.

Numerous reports of downed power lines were reported to Phoenix-area fire departments.

In the West Valley, two teenagers were struck by lightning in El Mirage.

The system also was impacting Roosevelt Dam, Four Peaks, Apache Lake and Tonto National Monument, the Weather Service said. The storm was moving toward the Valley.

The Weather Service recommends that people on or near Roosevelt Lake get out of the water and move indoors or inside a vehicle because of the possibility of lightning strikes.

“Move to safe shelter now! do not be caught on the water in a thunderstorm,” the Weather Service said.
