Lusandra and Dick Lange counted their belongings - and blessings - Tuesday morning after a microburst 12 hours earlier wreaked havoc on their east Mesa mobile home.

The couple also looked ahead to Wednesday and beyond with trepidation, although a spokeswoman for the National Weather Service in Phoenix said an encore of Monday's severe weather is unlikely. Rain and thunderstorms are forecast Wednesday and Thursday evenings, but likely not as strong as the reported 0.55 to 0.87 of an inch Monday in Mesa, according to meteorologist Valerie Meyers.

The Langes dread the thought of more rain being dumped on what's left of the aluminum roof of the Arizona room on their trailer at SunLife RV Resort in east Mesa. The majority of it was among several roofs strewn on a street behind the Langes' space.

"We have a lot to be thankful for. No one was hurt," said Arlene Schrofer, whose unit across the street from the Langes' had minor damage. "I'll tell you what, when that came through, I wasn't so sure we'd be alive."

Meyers confirmed that the area of Higley Road and University Drive where the Langes and Schrofer live was hit by a microburst. Meyers said while microbursts aren't unusual as a byproduct of thunderstorms, they can't be predicted.

"It started to rain soft around 7:30 (p.m.), but then it picked up," Lusandra Lange said in the quiet of her former Arizona room where the tinkle of a wind chime belied the earlier chaos. "Around 8:05 we went into the bedroom and the whole trailer started shaking. We're from Minnesota, so we know what a storm is about. We've just never seen this here."

The storm did more damage. About 7,000 Mesa residents were left in the dark due to collapsed power poles. Mesa police said damaged or broken power lines felled trees throughout east Mesa, including near Southern Avenue and Power Road, Recker and McKellips roads, and Broadway and Sossaman roads.

As of Tuesday morning, Salt River Project had 450 customers without power, down from 12,000 at the height of the storm Monday night. Spokesman Scott Harelson said crews were working to switch lines and string new ones to the hardest-hit areas at Southern and Recker, where 15 poles went down, and between 96th Street and Crismon Road on McKellips, where 10 toppled.

Meyers of the weather service said rainfall thus far this month at Phoenix Sky Harbor International Airport measures at 2.15 inches, up from the July average of .99 of an inch. While average annual rainfall there measures at 3.77, Meyers said it's already at 4.57 for this year.

The Langes, whose power was back on Tuesday morning, said their rain gauge didn't work. Dick Lange figured they got abouthalf an inch. He said the couple's insurance agent told him to load their belongings into a storage pod and leave.
