A wildfire burning south of Jamul Saturday has scorched 300 acres and was spreading west at a “dangerous rate,” Cal Fire said.
The blaze, called the Gate fire, was reported at Otay Lakes Road about 11:20 a.m. There was zero containment as of 12:50 p.m., Cal Fire reported.
The California Highway Patrol has shut down Otay Lakes Road south of state Route 94, and motorists are advised to avoid the area.
Nearby Pio Pico RV Resort and Campground was being evacuated. The area is otherwise largely undeveloped.
Five airtankers and three helicopters were making drops on fire, said Cal Fire Capt. Isaac Sanchez. Fire crews from several agencies were helping on the ground.
Smoke from the blaze could be seen from many parts of the county.
Temperatures were at 91 degrees by midday in the area and expected to rise over the next few hours, according to the National Weather Service. Relative humidity was at 10 percent, and winds blowing out of the southwest were gusting to 21 mph.
A sea breeze is shifting ashore but won’t reach Pio Pico.
