Small fire chars Sorrento Valley hillside

A roughly 1-acre fire charred a Sorrento Valley hillside west of Interstate 5 before dawn Friday, but was doused before it could threaten homes at the top.

Passing motorists reported seeing flames north of the I-5 split at Interstate 805 about 3:20 a.m.

Fire crews arrived to find about an acre of light brush burning, and flames moving uphill, north of Vista Sorrento Parkway, a San Diego Fire-Rescue Department dispatcher said.

The dispatcher said Copter 1 was sent to the blaze, but made no water drops before ground crews got the flames under control shortly after 4 a.m. Firefighters continued to thoroughly douse the area to make sure no hot spots remained.

The cause of the blaze was not immediately known.
