WANSHIP, Utah — A wildfire threatened hundreds of homes on Wednesday after destroying more than a dozen others outside the resort town of Park City.
The lightning-sparked blaze was among several in the West where fires have devoured dry grass and brush and burned to the edges of small communities.
Shifting winds in Utah pushed the fire toward homes in a subdivision about 10 miles outside Park City. It destroyed a dozen homes on Tuesday, plus another home overnight. Fire officials say it also burned 20 outbuildings and several vehicles and boats.
The fire began near a populated area and quickly grew to more than 1,200 acres, or nearly 2 square miles. Flames flared Wednesday with rising temperatures and winds.
‘‘We had a lightning strike and within 20 minutes it was up to about 20 acres and it just shot up the hill,’’ said Kevin Callahan, the county’s emergency manager.
