Firefighters on the northwest front focused on fortifying defenses and advancing tactically, while on the eastern front, crews and aerial resources increased surveillance, expanded containment, and directed the fire towards the 411 road intersection; today, they'll maintain vigilance due to anticipated wet weather.
Operations: Yesterday, crews on the northwest fire perimeter worked on improving hand lines, scouting containment lines, and familiarizing with the area as tactical firing operations continue to move west toward FSRD 411. Crews and aerial resources on the eastern perimeter of the fire continued monitoring, building depth, and bringing fire south down the 512 road to the 411 road intersection. Today, resources will hold and monitor as wetting rains and scattered storms are expected across the fire area.
Fire Ecology: One of the first things that fire has to do to a piece of fuel in order for it to burn is to drive the moisture out of it, and that takes a lot of energy. The more moisture, the more heat the fire has to ‘spend’ to get a piece of fuel to burn (a leaf or a needle or a twig). Fire managers monitor moisture levels in the leaves of some of the types of vegetation that are likely to burn in a fire. The more moisture, the less likely they are to burn or, if they do burn, the more moderate the fire behavior will be because it takes a LOT of energy to drive the moisture out of the leaves so they can burn.
Weather: Yesterday, conditions were dryer than previous days, as much of the moisture remained to the east of the fire area. Today, scattered showers and wetting rains are expected through Wednesday. Thursday will see a shift back to warmer and dryer weather that will last through the weekend.
