Officials said the blaze is near Angelus Oaks, but is burning actively upslope toward San Bernardino Peak in the northwest "as it aligns with canyons and upslope wind influence." Weather conditions remain dry and hot with "unstable air over the fire area."
Several miles to the north, a big cloud of smoke floated over Big Bear Lake. Officials ask visitors to reschedule planned visits to the Big Bear area due to the fire.
The cause of the fire was blamed on a smoke-generating pyrotechnic device used during a gender reveal party.
Four homes have been destroyed and two others have been damaged due to blaze.
