Several Days of Santa Ana Winds Threaten Southern California with Critical Fire Weather

The National Weather Service has issued a Red Flag Warning for much of the Southern California region from today around 1800 hours through Saturday around 2200 hours PST. A moderate to strong Santa Ana event will impact the area with winds gusting up to 65 mph and relative humidity as low as 5%. These conditions, combined with warm temperatures may contribute to extreme fire behavior.

The strongest winds are likely for Thursday between 0600 and 1500 PST, with the foothills and canyons most at risk. Santa Ana winds will weaken Thursday night and Friday, however single digit humidity values will remain. Poor overnight recoveries are expected, with the driest day on Friday.

The forecast predicts dry offshore wind at least through Tuesday. Therefore, Red Flag conditions could continue for the area heading into next week.

Critical Fire Weather Conditions Early This Week

Large fire activity picked up over the weekend, especially in the Southwest and Alaska areas. Currently the 30 active, large fires across five states have burned more than 65,000 acres bringing the total for the year to 550k, well below average for this time of year. This week could increase that total as high pressure is approaching the West Coast and will provide a warming and drying trend for most of the southern West. Breezy westerly winds are expected across Arizona and New Mexico and strong northeasterly winds with some of the lowest RH readings of the year across California. In tandem, the conditions will lead to elevated and critical fire weather concern (including red flag warnings) in many places.
