''My husband said, 'Yell at her, yell at her! That tree's going to fall on her,' '' Juarez recalled after thunderstorms swept across northern Utah, upending trees and felling power lines.

Juarez shouted out to her neighbor, who looked up to see the 120-foot cottonwood toppling over her head. She darted and fell to the ground.

The tree landed about 2 feet away, Juarez said. An ambulance took the woman to the hospital.

Another section of branches crashed onto the woman's house, Juarez added. Meanwhile, other neighbors were shoring up their tottering tree with boards as the winds howled.

"Yeah, I was kind of scared," Juarez said.

Juarez's neighborhood near 400 N. 1025 West is not the only one on clean-up duty today. Dispatchers from the Idaho border to Provo fielded hundreds of calls Tuesday reporting electric fires, power outages and roof damage.

"It was just overwhelming," said Unified Fire Authority Capt. Jay Torgersen. "We had to triage calls as they came in."

Flooding was reported in Logan on Valley View Highway (200 North), a main thoroughfare on the west side of the city.

Logan maintenance workers were called out to remove debris from sewer grates and clear downed tree branches from the sidewalks.

The National Weather Service issued a severe thunderstorm warning for Salt Lake, Davis, Tooele, Utah, Wasatch, Morgan, Weber, Cache and Juab counties around 7 p.m. The warning lasted for about an hour.

Winds raged in southwest Salt Lake County, where Salt Lake City Municipal Airport in West Jordan reported gusts as high as 67 mph.

"That's pretty big for being so close to the city," said Chris Gibson, a senior forecaster for National Weather Service.

At a Murray apartment building, the wind tore a carport into three sections, landing one in a tree, one on the building's roof and one propped against the building, said Murray Police Officer Mike Brimhall. The apartment building itself doesn't appear to have been damaged, but ''it's kind of a mess down here,'' Brimhall said.

The storm cut power to about 56,000 customers in Ogden, Tooele, Tremonton, the Salt Lake Valley and Utah County, said Rocky Mountain Power spokesman Jeff Hymas. Outages also were reported in Wellsville. As of 9:30 p.m., power was restored to about 4,000 homes; crews did not have an estimated time for total restoration, Hymas said.

"We're utilizing all available resources," he said.

Gibson said National Weather Service experts today will visit Grantsville, where residents reported seeing funnel clouds and snapped pictures of the ominous clouds that swelled up on the Tooele Valley.

"It was a very intense gust front," Gibson said. Meteorologists had not confirmed any tornadic activity Tuesday night.

The dust and rain impaired visibility for highway motorists, causing several to drive off the roadway, said Utah Highway Patrol Sgt. Jeff Nigbur. No serious injuries were reported.

Expect more stormy weather today, Gibson said. Forecasts show a 60 percent chance of showers and thunderstorms, with a high of 84 degrees.

"[Tuesday] was the last day of summer," he said.
