BISMARCK, N.D. (AP) - Temperatures climbed to 105 degrees in central and southwestern North Dakota while in the northwest, a storm pummeled the Williston airport and dropped a record amount of rain.

The National Weather Service warned of fire danger in the far southwestern part of the state because of the heat and wind. Bismarck and Dickinson reported 105 degree temperatures at 4 p.m., Central time, on Monday.

Wind gusts of up to 75 mph, shortly before 4:30 a.m., damaged six hangars and five single- and twin-engine airplanes, Williston airport manager Rick Marburger said.

"Two of the hangars were completely blown apart," Williams County Emergency Services Director Ed Lodwig said. "It looks like a straight wind that came through (the airport). There are trailer courts in the area, and they reported no damage."

Marburger said fuel tanks at the airport also were damaged but none leaked.

"A large portion of a hangar blew in through to the tank farm, wiped out the security fence and broke some fittings," he said.

Marburger said the airport was operating normally, but with a large mess to clean up. A damage estimate was not immediately available.

The National Weather Service said the storm dropped a record 1.33 inches of rain on Williston. The city's previous record for July 23 was 1.14 inches, set in 1912.

Heat during the summertime contributes to thunderstorm activity, though the severity of storms is not necessarily related to the intensity of the heat, said Janine Vining, a weather service meteorologist in Bismarck.

The extreme heat in parts of North Dakota that settled in over the weekend continued Monday, with the weather service posting a heat advisory for the southwest and south central parts of the state.

Forecasters said high temperatures and humidity would make it feel like 115 degrees in some areas.

The state Health Department issued hot weather safety tips, advising people to drink plenty of fluids, stay indoors and protect themselves from the sun.

Dickinson set a record high on Saturday with 102 degrees, topping the record of 100 degrees set in 1936. On Sunday, Grand Forks had a record high minimum temperature for the date, of 72 degrees. That broke the previous record of 68 degrees, set in 1964, the weather service said.

Vining said Minot was the only city likely to set a record high temperature on Monday. The city's record for the date was 99, set in 1980.

"They might equal or break it today," Vining said. "We're expecting upper 90s to around 100."

Bonnie Lund, a spokeswoman in Fargo for Xcel Energy, said the company had some heat-related outages in Minot over the weekend after a handful of transformers failed. An underground cable that failed Monday, causing an outage to about 1,400 Minot customers for a half hour, also likely was heat-related, she said.

Dan Sharp, a spokesman for Montana-Dakota Utilities, which serves central and western North Dakota, said MDU was expecting a peak demand late Monday afternoon, and should be able to handle it.

"We haven't had any incidents related to weather at all," he said. "We're a summer peaking company. We expect our peak demand to occur sometime during the summer. We build our electric system to accommodate that peak."
