A lighting sparked wildfire is raging near a Utah resort town where 13 homes have already been destroyed by the fast moving blaze.

The fire started in the Lake Rockport Estates subdivision near Park City, Utah. In addition to the homes, over 20 other buildings such as cabins and barns have been destroyed by the fire.

Spokeswoman Julie Booth told the Los Angeles Times that an additional 250 structures are in danger and that firefighters are trying to save them.

The fire is one of many in the last week that is connected to a series of lighting storms.

Booth said one of the problems facing firefighters is the shifting of the wind, which creates a “fire funnel” that makes the fire move faster than usual.

Between 1,200 and 1,500 acres have been burned as of Wednesday evening.
