This will be a PARTICULARLY DANGEROUS SITUATION (PDS) Red Flag Warning event in many areas, with the combination of strong upper level wind support, tight offshore pressure gradients (LAX-Daggett peaking at -7 to -8 mb), and moderate cold air advection. The strongest winds with this Santa Ana wind event are expected to be this morning into tonight when widespread damaging wind gusts of 60 to 80 mph are likely in the mountains and foothills of Los Angeles and Ventura Counties (including the Santa Monicas and Santa Susanas), with isolated gusts of 80 to 100 mph possible in favored areas of the San Gabriels. Similar winds are expected once again in the mountains Thursday night. For wind prone coastal and valley areas of Los Angeles and Ventura counties, damaging gusts of 50 to 70 mph will be likely (including the Malibu Coast and Ventura County coastal plain). Due to the strong upper level wind support, typical wind sheltered areas such as portions of the LA basin all the way to the coast, Lake Casitas and Ojai, as well as the Channel Islands and Catalina Island are expected to see gusty north to northeast winds with associated Red Flag conditions. Humidity levels are also expected to lower to between 8 to 15 percent by Wednesday afternoon with these low humidities likely to linger into Thursday and Friday. These are Extremely Critical and highly volatile conditions. Any new fires in the Red Flag Warning area -- and especially the PDS Red Flag Warning area -- will have rapid fire spread, extreme fire behavior, and long range spotting. * WINDS...Northeast winds will increase to 30 to 45 mph with damaging gusts to 55 mph through this evening. * RELATIVE HUMIDITY...Humidity levels will likely fall to between 8 and 15 percent by this afternoon. * IMPACTS...If fire ignition occurs, conditions are favorable for rapid fire spread and extreme fire behavior which would threaten life and property. With the threat of even stronger Santa Ana winds and drier fuels with the Wednesday/Thursday Santa Ana event, there will be an increased risk for long range spotting.

The strongest winds with this Santa Ana wind event are expected to be this morning into tonight when widespread damaging wind gusts of 60 to 80 mph are likely in the mountains and foothills of Los Angeles and Ventura Counties (including the Santa Monicas and Santa Susanas), with isolated gusts of 80 to 100 mph possible in favored areas of the San Gabriels. Similar winds are expected once again in the mountains Thursday night. For wind prone coastal and valley areas of Los Angeles and Ventura counties, damaging gusts of 50 to 70 mph will be likely (including the Malibu Coast and Ventura County coastal plain). Due to the strong upper level wind support, typical wind sheltered areas such as portions of the LA basin all the way to the coast, Lake Casitas and Ojai, as well as the Channel Islands and Catalina Island are expected to see gusty north to northeast winds with associated Red Flag conditions. Humidity levels are also expected to lower to between 8 to 15 percent by Wednesday afternoon with these low humidities likely to linger into Thursday and Friday. These are Extremely Critical and highly volatile conditions. Any new fires in the Red Flag Warning area -- and especially the PDS Red Flag Warning area -- will have rapid fire spread, extreme fire behavior, and long range spotting. * WINDS...Northeast 15 to 30 mph with gusts 35 to 50 mph, except to 70 mph over the northern Channel Islands. Strongest winds across higher terrain. * RELATIVE HUMIDITY...Lowering to 8 to 15 percent by this afternoon and lingering into Thursday. * IMPACTS...If fire ignition occurs, conditions are favorable for rapid fire spread and extreme fire behavior which would threaten life and property.

Air Quality Alert issued November 6 at 8:08AM PST by NWS Los Angeles/Oxnard CA

The Ventura County Air Pollution Control District has issued an Air Quality Alert due to increased particulate matter from blowing dust for all of Ventura County. This Air Quality Alert is IN EFFECT UNTIL 4 PM PST THURSDAY. VCAPCD Air Quality Alert for Blowing Dust from Wednesday November 6 at 7:00 am to Thursday November 7, 2024 at 4:00 pm. Strong Santa Ana winds will be dominant throughout the day stirring up high levels of dust throughout most of the county. For areas directly impacted by dust, particulate levels are likely to be elevated for several hours and could reach unhealthy levels. Please keep in mind Forecast AQI colors are meant to be as representative as possible for the 24-hr day. At times, air quality is likely to be better or worse than is indicated for the full day. If you are in an area directly impacted by dust, please exercise extreme caution and avoid vigorous outdoor or indoor exertion. People with respiratory or heart disease, the elderly, and children should remain indoors. Run your air conditioner if you have one. Keep the filter clean and fresh air intake closed. Close all windows and doors that lead outside to prevent bringing additional dust inside. If this is not an option or it becomes extremely hot inside, please seek alternate shelter. If you are experiencing a persistent cough 4 to 6 weeks after, please contact your doctor and ask about Valley Fever. For additional information, call the Ventura County Air Pollution Control District at 805.303.3889 (Monday-Friday), visit vcapcd.org, or follow VCAPCD on Twitter (@vcapcd) for the latest air quality updates.
