Officials say the fire is burning at a rapid rate of spread. It's caused a portion of the 71 freeway to close as of the afternoon.

As of Thursday morning, July 24, the Euclid fire had burned 120 acres in the Prado Dam area, according to Cal Fire San Bernardino and was 10% contained. Containment is the percentage of the blaze’s perimeter that won’t expand because of natural-terrain barriers, such as rocks or a water body, or firefighters’ work.

The Euclid fire started shortly after 2 p.m. near the 71 Freeway and Euclid Avenue. Cal Fire said initial reports listed the blaze as a vegetation fire, and it has grown to 120 acres.
