    ...PARTICULARLY DANGEROUS SITUATION (PDS) RED FLAG WARNING IN EFFECT UNTIL 10 AM WEDNESDAY DUE TO STRONG SANTA ANA WINDS AND VERY LOW HUMIDITIES FOR THE FOLLOWING AREA: SANTA SUSANA MOUNTAINS-- THEN RED FLAG WARNING IN EFFECT 10 AM TO 6 PM WEDNESDAY IN THIS SAME AREA... ...RED FLAG WARNING IN EFFECT UNTIL 6 PM WEDNESDAY DUE TO STRONG SANTA ANA WINDS AND VERY LOW HUMIDITIES FOR THE FOLLOWING AREAS: SAN GABRIEL MOUNTAINS/ SANTA MONICA MOUNTAINS/ SANTA CLARITA VALLEY/ VENTURA COUNTY COASTS AND VALLEYS/ WESTERN SAN FERNANDO VALLEY/ VENTURA COUNTY MOUNTAINS/ I5 CORRIDOR... ...RED FLAG WARNING IN EFFECT UNTIL 2 PM WEDNESDAY DUE TO STRONG SANTA ANA WINDS AND VERY LOW HUMIDITIES FOR THE FOLLOWING AREAS: VENTURA COASTAL PLAIN (ESPECIALLY FOOTHILLS) AND MALIBU COAST... 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. * WINDS...15 to 25 mph with gusts to 35 mph. * RELATIVE HUMIDITY...Widespread humidities of 8 to 15 percent. * 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. There is also the risk of damaging winds including trees and power lines, as well as power outages.More
