SAN DIEGO (KGTV) — Santa Ana winds and low humidity will bring fire danger to San Diego County this week.

Relative humidity is down to 10% to 15% in the county, according to the National Weather Service San Diego, causing localized fire weather conditions through Tuesday ahead of moderate to strong Santa Ana winds peaking on Thursday.

The high wind weather is expected to last Wednesday night into Friday, the NWS said. Winds will gradually weaken next weekend, but dry air will remain in the county.

"It is already starting out dry preceding this next event which is not good," the NWS wrote. "Relative humidity will plummet further and by Thursday, single-digit and teen relative humidity could drive all the way to the coast."

The county can expect to see temperatures steadily rise 5 to 10 degrees above normal west of the mountains and about 3 to 6 degrees above normal elsewhere into Tuesday, NWS says.

Despite this, cooler temperatures will work their way into the county overnight.

"Nights will remain cool, especially for the wind-sheltered areas. Local breezy conditions will continue below the passes and on the coastal slopes of the mountains each night and morning," NWS said.
