As surface high pressure builds into the Great Basin, Santa Ana winds are expected to increase late Monday morning into afternoon, then peak Monday night into Tuesday. 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, confidence is increasing for a long duration Red Flag event. In addition, there is the increasing potential for a high end Red Flag event across some of the windiest areas Monday night through Tuesday, as damaging wind gusts of 60 to 80 mph could overlap with single digit humidities across many of the wind prone 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. During the peak of this event (Monday night into Tuesday), there will likely be strong offshore pressure gradients, strong cold air advection from the interior, and moderate upper level wind support. 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 the increasing potential 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.

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 late Monday morning into afternoon, then peak Monday night into Tuesday. 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 of PDS Red Flag Warning conditions late Monday 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 foothills 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 the increasing potential 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.

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.

A strong Santa Ana event will continue to bring widespread critical to extremely critical fire weather conditions to many areas of Los Angeles and Ventura counties through Wednesday. For the Santa Susana Mountains, a PARTICULARLY DANGEROUS SITUATION (PDS) Red Flag Warning will continue into Wednesday morning, while elsewhere over wind-prone areas of Ventura and Los Angeles Counties Red Flag conditions will persist through Wednesday afternoon. Santa Ana winds will continue into Wednesday. The offshore winds are expected to diminish some by Wednesday, but a very dry air are likely today, persisting into Wednesday, mass will persist. Widespread single digit humidities can be expected through Wednesday. There is high confidence of PDS Red Flag Warning conditions through Wednesday morning for the Santa Susana Mountains, with gusts up to 55 mph possible. Peak gusts of 40 to 50 mph will also affect most wind prone coastal and valley areas of Los Angeles and Ventura counties through Wednesday morning. With the threat of these strong wind gusts in these windier corridors, there will be an increased risk for downed tree limbs and powerlines, along with power outages. The hardest hit areas will continue to 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. Due to the expected long duration of dangerous fire weather conditions and critically dry fuels, there is the increased risk for any new ignitions to have very rapid fire spread and extreme fire behavior (including long range spotting). Dry offshore conditions will likely persist into Wednesday night, shifting onshore on Thursday.

As surface high pressure builds into the Great Basin, Santa Ana winds are expected to increase late Monday morning into afternoon, then peak Monday night into Tuesday. 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, confidence is increasing for a long duration Red Flag event. In addition, there is the increasing potential for a high end Red Flag event across some of the windiest areas Monday night through Tuesday, as damaging wind gusts of 60 to 80 mph could overlap with single digit humidities across many of the wind prone 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. During the peak of this event (Monday night into Tuesday), there will likely be strong offshore pressure gradients, strong cold air advection from the interior, and moderate upper level wind support. 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 the increasing potential 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.

In addition, there is high confidence of of PDS Red Flag Warning conditions late Monday evening through Tuesday, as damaging wind gusts of 60 to 80 mph could overlap with single digit humidities across many of the wind mountain and foothills 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 the increasing potential 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.

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.

A strong Santa Ana event will continue to bring widespread critical to extremely critical fire weather conditions to many areas of Los Angeles and Ventura counties through Wednesday. For the Santa Susana Mountains, a PARTICULARLY DANGEROUS SITUATION (PDS) Red Flag Warning will continue into Wednesday morning, while elsewhere over wind-prone areas of Ventura and Los Angeles Counties Red Flag conditions will persist through Wednesday afternoon. Santa Ana winds will continue into Wednesday. The offshore winds are expected to diminish some by Wednesday, but a very dry air are likely today, persisting into Wednesday, mass will persist. Widespread single digit humidities can be expected through Wednesday. There is high confidence of PDS Red Flag Warning conditions through Wednesday morning for the Santa Susana Mountains, with gusts up to 55 mph possible. Peak gusts of 40 to 50 mph will also affect most wind prone coastal and valley areas of Los Angeles and Ventura counties through Wednesday morning. With the threat of these strong wind gusts in these windier corridors, there will be an increased risk for downed tree limbs and powerlines, along with power outages. The hardest hit areas will continue to 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. Due to the expected long duration of dangerous fire weather conditions and critically dry fuels, there is the increased risk for any new ignitions to have very rapid fire spread and extreme fire behavior (including long range spotting). Dry offshore conditions will likely persist into Wednesday night, shifting onshore on Thursday.
