The MODIS maps display the Moderate Resolution Imaging Spectroradiometer (MODIS) fire detection data, which is collected via satellite. Thermal data, for the northern hemisphere, is collected twice a day, at 12:00 AM EST and 2:00 PM EST. Color Coding Legend: Red Circles: fire activity within the last 0-12 hours Orange Circles: fire activity within the last 12-24 hours Yellow Circles: Fire activity within the last 24-48 hours Burn area and perimeter lines of current fires are usually shown in yellow, though occasionally for some fires they are green. Perimeter lines of previous fires from this fire season are shown in gray.

SOUTHERN CALIFORNIA • High pressure off the Southern California coast will give way to an approaching trough by the middle of the coming week with cooler/windier weather expected. • Highs today will be in the 90s to near 100 across the inland valleys, with 80s in the mountains, cooling to a little below normal levels by mid- week. • NW winds 10-20 mph each afternoon along the central coast and SW-W 15-25 mph across the Antelope Valley, Apple Valley and along the eastern slopes of the Cleveland national forest. Winds increasing Tuesday and Wednesday, especially along the eastern slopes of the Sierra. • Relative Humidity (RH) will drop into the 10-15% range above and away from the marine layer each afternoon. • The marine layer will deepen with night and morning low clouds and fog spreading into the coastal valleys starting Monday. -- 3 -- Red Flag Warnings/Watches & Air Quality Red Flag Warnings & Watches North America Smoke Plumes As of September 10, 2018 @ 1:21am September 9, 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 9/10 12:00am PT) for Monday, September 10 Source: https://www.airnow.gov Legend: AQI = Air Quality Index; PM = Particulate Matter; O3 = Ozone Air Quality Index Basics Overview: https://airnow.gov/index.cfm?action=aqibasics.aqi -- 4 -- Significant Fire Potential Maps Monday Tuesday Wednesday Thursday Friday Saturday Source: http://psgeodata.fs.fed.us/staticmap.html -- 5 -- Natchez Fire - Del Norte & Siskiyou Counties Sources reference number (#) corresponds to number in the information sources at the end of the section.

All fuel types are burning readily and contributing to active fire spread. (1) 24hrs: Breezy ridgetop conditions and moderate relative humidity will provide active burning conditions. Active surface spread with isolated torching. Fire will continue to move west in South Fork Indian Creek Canyon toward Raspberry Gap, and south in Tenmile Creek into unburned islands between 2017 Eclipse burn and Natchez fire. (1) 48hrs: Active surface spread with intermittent torching and short range spotting. Fire will continue to move west in South Fork Indian Creek Canyon toward Raspberry Gap, and south in Tenmile Creek into unburned islands between 2017 Eclipse burn and Natchez fire. (1) 72 hrs and beyond: Moderating fire activity with cooling and moistening airmass. Fire activity in upper elevations expected to be primarily creeping / smoldering, with continued active surface spread with intermittent torching in richer lower elevation fuels left in gaps between 2017 Eclipse burn and Natchez fire. Decreased smoke production. (1) Continued on Next Page -- 6 -- Natchez Fire - Del Norte & Siskiyou Counties Evacuations Evacuation Warning: • three private in-holdings northwest of Happy Camp.
