October Rain: Tracking storms in the valley

PHOENIX (AP) -- A line of thunderstorms has dropped up to an inch of rain on some parts of the Phoenix metropolitan area. National Weather Service meteorologists say some cities west and south of Phoenix were the hardest hit by Tuesday's storms, which also brought hail and strong winds.

The Flood Control District of Maricopa County reported some rain gauges hitting as high as 1.3 inches of rain by 1 p.m. In Goodyear, police say some roads around the city were flooded in low-lying spots.

Phoenix Sky Harbor International Airport reported departure delays between 30 and 45 minutes at one point Tuesday afternoon due to lightning in the area.

The storm was associated with a low-pressure system that was centered over Southern California on Monday and moved into Arizona.

The National Weather Service issue a small stream flood advisory for central Maricopa County until 3:30 p.m. MST. At 12:30 p.m., doppler radar indicated heavy rain due to thunderstorms. Per NWS, locations that will experience flooding include Avondale, Goodyear, Buckeye, Tolleson, Cashion, Estrella Mountain Park, Cotton Center, Liberty, Phoenix International Raceway, Perryville, Estrella Mountain Ranch and Rainbow Valley.

The Arizona Department of Transportation says if you're planning on heading into the Phoenix area, delaying your trip might be safer.
