Santa Barbara County 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 Santa Barbara County.

Air Quality Alert issued November 5 at 2:33PM PST by NWS San Diego CA

* WHAT...The South Coast AQMD has issued an air quality alert due to harmful levels of particle pollution from windblown dust. * WHERE...in the Coachella Valley and parts of inland areas of Orange County and the Inland Empire. Levels of particle pollution can vary by time and location depending on emissions and local weather conditions. * WHEN...from 5 AM Wednesday to 2 PM Thursday. * IMPACTS... Particle pollution can get deep into the lungs and cause serious health problems such as asthma attacks, heart and lung disease symptoms, and increased risk of lung infections. Everyone can be affected, but sensitive groups such as people with lung or heart disease, older adults, people who are pregnant, children, and those who spend a lot of time outdoors are at greater risk.

This will be a PARTICULARLY DANGEROUS SITUATION (PDS) Red Flag Warning event in many areas, with the combination of strong upper level wind support, tightening offshore pressure gradients (LAX-Daggett peaking at -7 to -8 mb), and moderate cold air advection. The strongest winds with this 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. Similar winds are expected once again in the mountains Thursday night. 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 all the way to the coast, 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 conditions. 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 and Friday. These are Extremely Critical and highly volatile conditions. Any new fires in the Red Flag Warning area -- and especially the PDS Red Flag Warning area -- will have rapid fire spread, extreme fire behavior, and long range spotting. In addition, there will be gusty north to northeast winds overlapping with humidities around 10 to 20 percent late this afternoon into tonight 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 under a Red Flag Warning for late today into tonight, with gusts of 35 to 55 mph being common, except isolated gusts up to 60 mph. * WINDS...North to northeast 20 to 40 mph with gusts 40 to 55 mph. Isolated gusts to 60 mph across favored ridgetops. * RELATIVE HUMIDITY...10 to 20 percent. * 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.

Similar winds are expected once again in the mountains Thursday night. 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 all the way to the coast, 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 conditions. 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 and Friday. These are Extremely Critical and highly volatile conditions. Any new fires in the Red Flag Warning area -- and especially the PDS Red Flag Warning area -- will have rapid fire spread, extreme fire behavior, and long range spotting. In addition, there will be gusty north to northeast winds overlapping with humidities around 10 to 20 percent late this afternoon into tonight 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 under a Red Flag Warning for late today into tonight, with gusts of 35 to 55 mph being common, except isolated gusts up to 60 mph. * WINDS...Northeast winds will increase to 35 to 50 mph with damaging gusts of 60 to 80 mph Wednesday into Wednesday night. Local gusts to 100 mph. Offshore Winds are expected to be 5 to 10 mph weaker on Thursday and into Friday. * RELATIVE HUMIDITY...Humidity levels will likely fall to between 8 and 15 percent by Wednesday afternoon, and linger into Thursday and Friday. * 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.

Air Quality Alert issued November 5 at 11:58AM MST by NWS Phoenix AZ

The Imperial County APCD has issued an air quality alert due to increased particle pollution from blowing dust. The air quality alert is in effect from 1 AM to 7 PM Wednesday November 6th. In areas directly impacted by high levels of windblown dust, limit your exposure by remaining indoors with windows and doors closed and avoiding vigorous physical activity. Run your air conditioner or an air purifier. If temperatures allow, avoid using whole house fans or swamp coolers that bring in outside air. Exposure to high particle pollution levels can cause serious health problems, including asthma attacks, heart and lung disease symptoms, and increased risk of respiratory infections. People with heart or lung diseases should follow their doctor's advice for dealing with episodes of unhealthy air quality. Children, older adults, and people with respiratory or heart disease should avoid prolonged exposure and strenuous activities when particle pollution levels are high. To help minimize outdoor particle pollution levels: * Carpool, telecommute, reduce trips, or take public transportation * Slow down if driving on dirt roads * Stabilize loose soils Levels of particle pollution can vary hour by hour and by location depending on wind conditions.
