This will be a PARTICULAR DANGEROUS SITUATION (PDS) Red Flag Warning event in many areas, with the combination of a strong offshore pressure gradient (LAX-Daggett peaking at -8 to -9 mb), strong cold air advection, and moderate upper level wind support. As surface high pressure builds into the Great Basin, Santa Ana winds are expected to increase through the afternoon, then peak tonight into Tuesday. A marine layer cloud presence this morning may delay the onset of offshore winds across portions of the coast and coastal valleys by a few hours from what was expected yesterday. Offshore winds are expected to diminish some by Wednesday, but very dir will persist. With the strong likelihood of widespread single digit humidities with this event, there is high confidence for a long duration Red Flag event. In addition, there is high confidence of PDS Red Flag Warning conditions late this evening through Tuesday, as damaging wind gusts of 60 to 80 mph will likely overlap with single digit humidities across many of the windier mountain and foothill areas, and with gusts of 40 to 65 mph across most wind prone coastal and valley areas of Los Angeles and Ventura counties. With the threat of damaging wind gusts in these windier corridors, there will be an increased risk for downed trees and powerlines, along with power outages. The hardest hit areas will likely be the San Gabriels, Santa Susanas, western Santa Monicas into Malibu, Ventura county valleys (especially Simi Valley and Moorpark), western San Fernando Valley (especially Highway 118/210 corridors from Porter Ranch to San Fernando), and the hills above Camarillo into east Ventura. Due to the expected long duration of dangerous fire weather conditions and critically dry fuels, there is an increased risk for any new ignitions to have very rapid fire spread and extreme fire behavior (including long range spotting). As a result, there is the increasing threat for fire weather conditions to rival other historical fires in recent times including the Mountain and Thomas Fires. Dry offshore conditions will likely persist into Thursday morning, with a return of onshore flow and some humidity recovery in the afternoon. The National Weather Service in Los Angeles/Oxnard has issued a Red Flag Warning for gusty Santa Ana winds and very low relative humidity, which is in effect from 8 PM this evening to 2 PM PST Tuesday. * WINDS...Santa Ana winds expected to increase this evening, then peak overnight into Tuesday morning. During the peak of the event, wind speeds of 15 to 30 mph with gusts to 40 mph can be expected, with the strongest winds focused across higher terrain. * RELATIVE HUMIDITY...Humidities are expected to lower to around 15 percent by this evening, with widespread humidities of 5 to 10 percent likely by Tuesday. * IMPACTS...If fire ignition occurs, conditions are favorable for large fires with very rapid fire spread, extreme fire behavior, and long range spotting, which would threaten life and property.
