A 100-acre brush fire prompted the evacuation of the Jurupa Mountains Discovery Center Friday.
The blaze was reported at 12:49 p.m. near Granite Hill Drive and Pyrite Street, along the westbound lanes of state Route 60, according to the Riverside County Fire Department.
Initially, fire officials said the blaze was between two and three acres and was burning in light flashy fuels at a moderate rate of spread. The fire quickly grew to 100 acres.
Evacuation orders were issued for the Jurupa Mountains Discovery Center, a mostly outdoor facility featuring earth science activities for families at 7621 Granite Hill Drive.
Authorities said Granite Hill Drive was closed in both directions.
Fanning the flames were gusty winds that were expected to reach up to 60 mph, according to the National Weather Service.
Riverside County mountains, deserts and passes are under a wind advisory until 6 p.m. Monday.
There were no reports of injuries or structures damaged by the fire.
