Snowfall Over the Fire Diminishes Fire Activity

Current Situation: The CalWood Fire received up to 13” of snow in the higher elevations and remains at 76%
containment. Minimal activity was seen across the fire on Sunday due to the winter storm. Minimal heat and smoke were
observed as containment lines continue to hold. Temperatures are expected to drop on Monday morning as a cold front
continues to move through the area.

Firefighters will continue to monitor the fire for hot spots or any movement. Fire activity is expected to be greatly
diminished due to the drop in temperature and recent snow fall. When it is safe to do so, crews will begin work to continue
increasing containment by improving and mopping up lines around the edge of the fire.

Fire managers will continue to monitor the weather to determine when it is safe for crews to get back onto the fireline and
work the edge of the fire. One method that crews will be utilizing for mop up is called “cold trailing.” Cold trailing is a
method of removing heat from the edge of the fire by carefully inspecting and feeling areas on the ground with the back of
a bare hand. If heat is detected, firefighters then use hand tools to dig out those areas to the release heat and add water to
cool the area.

Weather & Fuel Conditions: The forecast for Monday is mostly cloudy skies with highs near 16 degrees. Wind chill as
low as –3 degrees is possible. There is a 40 percent chance of snow, mainly before 11 a.m; total daytime snow
accumulation of less than one-half inch is possible. Winds are expected to be light and variable. This evening will be
mostly clear, with a low around 5 degrees and wind chill as low as -5 degrees. Record lows are possible overnight into
Tuesday morning. Snow cover will remain on the ground into Tuesday morning. A gradual warm-up will follow with
highs in the 30s on Tuesday and in the 40s on Wednesday and Thursday.
