PHOENIX -- Forecasters said there could be more thunderstorms in Arizona on Tuesday as the Phoenix area cleans up from the second damaging monsoon storm in two days.
A monsoon storm late Monday knocked down numerous trees in east Phoenix, leaving many fallen tree trunks and limbs in yards and on streets. High wind also knocked down a traffic light pole.
Power was knocked out in several neighborhoods, affecting thousands of customers, and flooding disrupted traffic.
In north Phoenix, firefighters used ropes and a pulley system to rescue a 56-year-old motorist after she tried to cross a wash. Georgia Arneson said there was only a little water in the wash when she drove into it but that a wave of water carrying debris trapped her.
Elsewhere in Arizona, an Arizona Department of Public Safety officer was hospitalized in serious condition after being injured when his patrol vehicle crashed near Payson on State Route 87. A DPS spokesman said the single-vehicle accident was related to weather.
The National Weather Service forecasts heavy rain and potential for flooding in parts of Arizona Tuesday. Scattered thunderstorms are expected to develop in the central and eastern mountains and then move toward the lower deserts.
However, the weather service said dry air is expected to move into the region on Wednesday, limiting thunderstorms to higher terrain north and east of Phoenix.
A storm late Sunday caused similar damage in Phoenix-area suburbs and in the Tucson area, where high wind flipped a retired F-16 onto another aircraft at Davis-Monthan Air Force Base.
