SAN DIEGO (CNS) - The combination of gusty winds, low humidity and warm weather Sunday could raise the risk for wildfires in San Diego County's mountains and inland valleys forecasters said.
The wind and low humidity prompted the National Weather Service to issue a Red Flag Warning, which started at 10 a.m. and will extend to 4 p.m. Monday for inland valleys and mountain areas. That area includes the Palomar and Descanso ranger districts of the Cleveland National Forest.
"A Red Flag Warning means that critical fire weather conditions are either occurring now, or will shortly," according to the NWS. "A combination of strong winds, low relative humidity and warm temperatures will create explosive fire growth potential."
High temperatures in the valleys could reach 71 degrees Sunday and around 73 degrees Monday. Highs in the mountains could reach 67 degrees Sunday and 63 degrees on Monday.
Forecasters said the strongest winds, with gusts of up to 50 miles per hour, would be likely tonight and Monday morning.
Northeast winds of between 15 and 25 mph could be possible with gusts of up to 45 mph. Gusty wind of around 35 mph could continue near the coastal foothills through Tuesday, forecasters reported.
A wind advisory was also issued for the valleys and mountains set to go into effect at 6 p.m. and extend until 2 p.m. Monday.
The NWS advised the wind could make driving difficult, especially for those in high-profile vehicles. Motorists should use extra caution and keep an eye out for broken tree limbs and downed power lines.
