Red Flag Warning issued November 4 at 9:54AM PST until November 4 at 6:00PM PST by NWS Los Angeles/Oxnard CA

...RED FLAG WARNING IN EFFECT UNTIL 6 PM TODAY ACROSS PORTIONS OF LOS ANGELES AND VENTURA COUNTIES DUE TO GUSTY SANTA ANA WINDS AND LOW HUMIDITIES... ...FIRE WEATHER WATCH IN EFFECT TUESDAY NIGHT FOR MOUNTAINS/FOOTHILLS OF SAN LUIS OBISPO/SANTA BARBARA COUNTIES... ...FIRE WEATHER WATCH IN EFFECT LATE TUESDAY NIGHT THROUGH THURSDAY FOR MUCH OF LOS ANGELES AND VENTURA COUNTIES DUE TO POTENTIAL FOR STRONG SANTA ANA WINDS WITH LOW HUMIDITIES... .For today, Santa Ana winds are peaking this morning, and will gradually diminish through the afternoon and evening hours. Peak gusts are generally in the 30 to 50 mph range across typical wind prone area of Los Angeles and Ventura counties (including the Malibu coast), except the Los Angeles county mountains where gusts of 50 to 70 mph are being observed. Humidity levels between 15 and 25 percent are common this morning, and will fall to between 10 and 20 percent across much of the wind prone areas today. There is increased confidence of a stronger, more widespread, and longer duration Santa Ana wind event which will likely bring widespread critical fire weather conditions to wind prone areas of Los Angeles and Ventura counties Wednesday into Thursday. Fire Weather Watches will likely be converted to Red Flag Warnings later today. This appears to be a high end Red Flag Warning event with the combination of strong upper level wind support, tightening pressure gradients (LAX-Daggett peaking at around - 7 mb), and moderate cold air advection. The strongest winds with this upcoming Santa Ana wind event are expected to be Wednesday morning into Wednesday night when widespread damaging wind gusts of 60 to 80 mph are becoming likely in the mountains and foothills of Los Angeles and Ventura counties (including the Santa Monicas and Santa Susanas), and widespread gusts of 45 to 60 mph across coastal/valley areas (including the Malibu coast and Ventura county coastal plain). 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. In addition, there will be gusty north to northeast winds overlapping with humidities around 15 to 20 percent late Tuesday afternoon into Tuesday night across the mountains and foothills of San Luis Obispo and Santa Barbara counties, where a Fire Weather Watch remains in effect and will likely be converted to Red Flag Warnings later today. Also of note, elevated to brief critical fire weather conditions are likely for southern Santa Barbara county during this time, and Red Flag Warnings may need to be considered for these areas as well. ...FIRE WEATHER WATCH REMAINS IN EFFECT FROM LATE TUESDAY NIGHT THROUGH THURSDAY AFTERNOON FOR STRONG SANTA ANA WINDS AND LOW RELATIVE HUMIDITY FOR THE MOUNTAINS OF LOS ANGELES COUNTY... * WINDS...Northeast 25 to 40 mph with damaging gusts up to 60 mph this morning, gradually diminishing in the afternoon. Isolated gusts 60 to 70 mph across the San Gabriels. Offshore winds will diminish some on tonight into Tuesday, then increase to 30 to 50 mph with potential for widespread damaging gusts of 60 to 80 mph on Wednesday. * RELATIVE HUMIDITY...Falling to between 10 and 20 percent today. Humidity levels will likely fall to between 8 and 15 percent with the second Santa Ana wind event Wednesday afternoon, and linger into Thursday. * 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.

Red Flag Warning issued November 4 at 9:22AM PST until November 7 at 7:00AM PST by NWS San Francisco CA

...RED FLAG WARNING IN EFFECT TUESDAY MORNING THROUGH THURSDAY MORNING FOR THE BAY AREA AND CENTRAL COAST AS STRONG OFFSHORE WINDS AND CRITICALLY DRY CONDITIONS ARE EXPECTED TO DEVELOP... .Offshore winds are anticipated to increase early Tuesday morning and persist through Thursday morning. North to northeasterly wind gusts will average between 25 and 50 mph, particularly across the higher terrain of the Santa Cruz Mountains, East Bay Hills, North Bay Mountains, as well as interior portions of Napa and Sonoma counties. In particular, these areas of Napa and Sonoma counties have an increased likelihood of wind gusts in excess of 55 mph late Tuesday and through the day on Wednesday. Afternoon humidity values will fall to between 15 and 25 percent. Overnight humidity recovery will be poor with readings between 25 and 45 percent. The combination of the aforementioned winds and humidity will translate to fires exhibiting a large resistance to control and thereby creating a hazardous and extreme wildfire environment. Fire crews and residents are urged to remain abreast of the weather forecast over the next couple of days. * AFFECTED AREA...Fire Weather Zone 006 San Francisco, Fire Weather Zone 502 Marin Coastal Range, Fire Weather Zone 503 Sonoma Coastal Range, Fire Weather Zone 504 North Bay Interior Mountains, Fire Weather Zone 506 North Bay Interior Valleys, Fire Weather Zone 508 San Francisco Bay Shoreline, Fire Weather Zone 509 San Francisco Peninsula Coast, Fire Weather Zone 510 East Bay Interior Valleys, Fire Weather Zone 512 Santa Cruz Mountains, Fire Weather Zone 513 Santa Clara Valley Including San Jose, Fire Weather Zone 514 Eastern Santa Clara Hills, Fire Weather Zone 515 East Bay Hills, Fire Weather Zone 517 Santa Lucia Mountains and Los Padres National Forest, Fire Weather Zone 518 Mountains of San Benito County And Interior Monterey County including Pinnacles National Park and Fire Weather Zone 529 Northern Monterey Bay. * TIMING...11 AM Tuesday until 7 AM Thursday. * WINDS...Offshore winds up to or above 25 mph with gusts in excess of 55 mph. * RELATIVE HUMIDITY...Afternoon humidity as low as 15%. Overnight humidity recovery between 25 and 45%. * LIGHTNING...None anticipated. * IMPACTS...Despite recent rainfall, a long duration offshore flow event is anticipated. This will result in the rapid curing of fuels. The combination of strong winds and low humidity will cause fire to rapidly grow in size and intensity. Outdoor burning is not recommended and may be prohibited in some areas.

High Surf Advisory issued November 4 at 8:43AM PST until November 6 at 9:00AM PST by NWS Los Angeles/Oxnard CA

* WHAT...Large breaking waves of 8 to 13 feet with dangerous rip currents. Highest surf will occur at west and northwest facing beaches. * WHERE...San Luis Obispo County Beaches and Santa Barbara County Central Coast Beaches. * WHEN...Until 9 AM PST Wednesday. * IMPACTS...There is an increased risk for ocean drowning.
