Afternoon SW-W winds from the Cascade-Sierra crest east and through the Bay Area and Delta will gust to 25 mph with a few spots up to 30 mph. In far northern areas NW-NE winds will gust to 25-30 mph over the higher terrain during afternoons and evenings through Saturday. Temperatures throughout the region will be near normal through Saturday. Inland relative humidity (RH) will continue to be 8-18% east of the crest and 12-25%. The marine layer has deepened to 2500-3000 feet and moved through the coastal range and into the Sacramento Valley overnight. Some inland mid and upper slope locations will still only see RH recovery to 35-45%, but in general overnight RH recovery has improved quite a bit. The trough will move off to the east on Sunday. SW-W winds near and east of the northern CA-NV state line will gust to 30-40 mph Sunday afternoon with RH continuing in the 8-18% range. A few light showers are possible in far NE CA and NW NV Sunday night and early Monday. The remainder of the region will be dry and cooler than normal with local NW-NE breezes Sunday and Monday. By Tuesday another low pressure trough will set up over the region and produce dry and mild conditions. SOUTHERN CALIFORNIA Several troughs over the Pacific Northwest will maintain a southwesterly flow aloft, resulting in temperate weather and a lack of convection through the period. Wednesday, a handful of storms developed near Desert Center, but no further thunderstorm activity is expected through the first half of next week. High temperatures will show little variation the next few days and will remain within a few degrees of seasonal averages. Highs will range from the 70s and lower 80s in the mountains to the mid 90s in the San Joaquin Valley. Minimum RH will drop into the teens for 6-8 hours each day above 3,000 feet. RH recovery should be good, except along the I-5 Corridor and across Southern Santa Barbara County where local north winds of 10-15 mph will be possible the next 3 nights. There will be afternoon sea breezes of 15-25 mph along the central coast and in the desert interface areas during the afternoon hours. A deeper trough passing to our north may result in gusty winds of 25-35 mph in and near the desert Sunday and Monday. Warmer weather may return during the second half of next week. -- 4 -- Red Flag Warnings/Watches & Air Quality Red Flag Warnings & Watches North America Smoke Plumes August 24, 2018 = Fire Weather Warning = Fire Weather Watch Source: https://www.ospo.noaa.gov/Products/land/hms.html Source: https://www.weather.gov/fire/ Current Watches, Warnings or Advisories for California Link https://alerts.weather.gov/cap/ca.php?x=1 Current Air Quality Air Quality Forecast (as of 8/24 1:00am) for Friday, August 24 Source: https://www.airnow.gov (Note: Map image for California is currently unavailable due to high traffic volumes) Legend: AQI = Air Quality Index; PM = Particulate Matter; O3 = Ozone Air Quality Index Basics Overview: https://airnow.gov/index.cfm?action=aqibasics.aqi -- 5 -- Significant Fire Potential Maps Friday Saturday Sunday Monday Tuesday Wednesday Source: http://psgeodata.fs.fed.us/staticmap.html -- 6 -- Natchez Fire - Del Norte & Siskiyou Counties Sources reference number (#) corresponds to number in Information sources at the end of the section.

Smoke lift is expected during this burn period creating good ventilation, resulting in moderate to active fire behavior in the SW quarter of the fire area, where the fire is in a free burn state. Continue moderate spread of the main fire to the south towards Baldy Mountain where last year's fire perimeters are expected to provide a strong fuel brake. To the west fire expected to keep moving towards the Siskiyou Wilderness and a high elevation ridge range running from Lookout Mountain to Preston Peak. As fire moves towards the west and up several drainages, including Copper Creek, fuels become less continuous and more sparse. Fire is expected to check-up along the ridge line.
