Nipomo Warnings, Watches and Advisories

Do not drive vehicles through flooded areas. The water depth or fast flowing water/mud/debris from a flash flood will make road conditions unsafe. Do not rely soley on data presented here or other third-party websites - always check your official national and local weather service agency website, socials, radio and/or TV stations for making critical decisions related to weather events.

Please carefully read each posted Warning and Alert as it relates to the area(s) being affected. We may provide a wider range of issued severe weather warnings for surrounding cities and counties, so some alerts may not directly impact this location. This is done to help with preparing for severe weather that may overlap or be heading towards Nipomo.

Red Flag Warning issued November 4 at 6:48PM PST until November 6 at 4:00AM PST by NWS Los Angeles/Oxnard CA

...RED FLAG WARNING IN EFFECT 4 PM TUESDAY UNTIL 4 AM WEDNESDAY FOR MOUNTAINS AND FOOTHILLS OF SAN LUIS OBISPO AND SANTA BARBARA COUNTIES AND SANTA BARBARA SOUTH COAST... ...RED FLAG WARNING IN EFFECT 4 AM WEDNESDAY UNTIL 6 PM THURSDAY FOR MUCH OF LOS ANGELES AND VENTURA COUNTIES DUE TO STRONG SANTA ANA WINDS AND LOW HUMIDITIES... ...RED FLAG WARNING IN EFFECT 7 AM WEDNESDAY UNTIL NOON THURSDAY FOR INLAND LA COAST (ESPECIALLY HOLLYWOOD HILLS), OJAI/LAKE CASITAS, AND CHANNEL ISLANDS/CATALINA ISLAND... 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 many wind prone areas of Los Angeles and Ventura counties Wednesday into Thursday. This will be a high end Red Flag Warning event with the combination of strong upper level wind support, tightening offshore pressure gradients (LAX- Daggett peaking at -6 to - 8 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 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. 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 (mainly Hollywood Hills), 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 fire weather concerns. 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, as well as the Santa Ynez mountains, Santa Barbara south coast, and Highway 33 corridor. These areas are now under a Red Flag Warning for late Tuesday into Tuesday night, with gusts of 35 to 55 mph being common, except isolated gusts up to 60 mph. This is a dangerous fire weather event. Any new fires in the Red Flag Warning area will have rapid fire spread, extreme fire behavior, and long range spotting. * WINDS...North to northeast 20 to 35 mph with gusts 40 to 55 mph. Isolated gusts to 60 mph near Montecito Hills. * RELATIVE HUMIDITY...Lowering to 8 to 15 percent by Wednesday 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.

Red Flag Warning issued November 4 at 4:56PM 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.
