Santa Ana Winds, Heat, and Elevated Fire Danger Persist
Santa Ana winds take center stage today as a high-pressure system builds over the Southwest. The strongest winds swept through overnight, but gusts of 30 to 45 mph continue to impact canyons and mountain passes. A Wind Advisory remains in effect for inland and mountain communities through noon. Elevated fire danger is a concern as relative humidity stays in the teens.
Interior parts of the county will experience unseasonably warm weather, with potential record-breaking heat. Ramona is forecast to hit 82°F, surpassing its previous daily record of 80°F. Palomar Mountain could also break its record of 67°F with a high of 68°F expected today.
Moisture, Fog, and Cooling Ahead
Onshore winds will increase tonight, bringing additional moisture and the potential for coastal fog as a coastal eddy develops. Inland areas will remain warm on Thursday, but cooler conditions are on the way Friday and into early next week. A storm system could bring scattered showers and high winds just in time for Christmas Eve.
