San Diego County will be under a red flag warning from early Monday through Thursday afternoon due to Santa Ana winds and very low humidity, the National Weather Service says.
Forecasters say the dry, offshore winds will pick up speed Monday into Tuesday.
The winds are expected to gust 35 to 50 mph on Monday across inland valleys, and could be especially snappy in Ramona, Escondido, Alpine and Campo. Forecasters say the winds will surpass 50 mph in many inland spots on Tuesday, and could hit 20 to 30 mph at the coast, especially in North County.
“The relative humidity is going to drop on Monday, and by Tuesday it will be only 5 to 15 percent for most of the county,” said Brett Albright, a weather service forecaster.
“The low humidity is going to last all week.”
Santa Ana winds are usually associated with hot weather. However, temperatures will be in the 60s and 70s across most of the county because the wind storm is originating in a part of the country where the air will be cold.
