The National Weather Service in San Diego issued a high wind warning from midnight Thursday to 6 p.m. Friday, Nov. 9.
North to northeast winds at 15 to 25 mph with gusts up to 35 mph are expected to develop Thursday afternoon. They are expected to strengthen that evening with northeast winds 25 to 35 mph with gusts up to 55 mph.
NWS is warning that this could cause hazardous driving conditions, strong cross winds, and/or downed trees and power lines.
Another moderately strong Santa Ana event is expected Sunday afternoon through Monday.
The high wind advisory comes with a Red Flag Warning due to low humidity. Lowest humidity Thursday afternoon will fall to 5 to 10 percent. The recovery tonight will be poor with lowest humidity on Friday falling to around 5 percent.
“Low inland humidity with poor overnight recovery will continue through at least the middle of next week,” according to the NWS. Winds are expected to be weaker on Saturday. However, “Another round of moderate to locally strong Santa Ana winds is expected to develop on Sunday and continue into Monday with the strongest winds expected for late Sunday night into Monday. Periods of weak to moderate strength winds could continue through the middle of next week,” NWS wrote.
“Any fires that develop will likely spread rapidly with extreme fire behavior possible …
“A Red Flag Warning means that critical fire weather conditions are either occurring now … or will shortly. A combination of strong winds … low relative humidity … and warm temperatures can contribute to extreme fire behavior.”
