Fuel Reduction Practices and Purpose

The practice of hazardous fuel reduction is most often associated with moderating the flammable vegetation around the defensible space of individual homes and communities. But this proactive approach to fighting wildland fire comes in many other forms and, unlike fire-fighting in most areas, is a year-round practice.    Ridgeline fuel break example on the left and a road brushing/shaded […]

It’s Prescribed Fire Season

In many wildland areas, smoke can often be seen throughout the winter. More than likely, this is not due to uncontrolled wildfire, but rather prescribed fires that are started when the weather is less conducive to catastrophic burns, allowing firefighters and crews to prepare for when wildfire season picks up again.     A Rx fire (controlled pile burning) I helped ignite […]

Smoke Color Can Depict Fuel Type

Smoke is made up of particulates, aerosols and gases, and identifying the characteristics of each in a given smoke plume can be helpful when fighting fires. Reading smoke can tell a firefighter what is currently happening with a fire as well as what might happen in the future. One particularly important factor in predicting fire behavior is the color of […]

WildFire 101: Haines Index

Haines Index is used to indicate the potential for rapid fire growth due to dry and unstable atmospheric conditions over a fire area. The index is a simple way to measure the atmosphere’s contribution to the fire’s growth potential. A high Haines Index is correlated with large fire growth where winds do not dominate fire behavior. […]

Wildfire 101: Lightning Activity Level (LAL)

The Lightning Activity Level (LAL) is a measurement of cloud-to-ground lightning activity observed (or forecasted to occur) within a 30 mile radius of an observation site.    The LAL is part of the National Fire Danger Rating System (NFDRS) and consists of two reports. The first report covers the period from the previous day’s observation […]

Wildfire 101: Ignition

Since 2001, each wildfire season has averaged almost 73,000 ignitions and over 6.5 million acres burned in the U.S. Interestingly, the vast majority of these ignitions are human-caused, but the total acreage burned is mostly accredited to lightning-starts. Annually-collected statistics on ignitions show that 85% of all wildfire starts this century have been classified as human-caused. […]

Wildfire 101: Fire Anatomy

Wildland firefighters use very specific terminology to describe the various parts of a fire.  The fastest-moving portion is designated the “head” of the fire, the sides of the fire are known as the “flanks”, and the slowest moving portion is known as the “tail” or “heel” of the fire. The origin of the fire is […]

NASA’s JPL announces plan for more advanced wildfire detection by 2018

NASA’s Jet Propulsion Laboratory (JPL) has been refining a concept first proposed in 2011 for a network of space-based sensors called FireSat that would revolutionize the monitoring coverage of wildfires globally.   According to the JPL, “FireSat would be a constellation of more than 200 thermal infrared imaging sensors on satellites designed to quickly locate wildfires around […]

California’s Fire Potential Outlook for December

    Southern California: Normal significant wildland fire potential is expected for Southern California for the outlook period. Weather and Fuels: After a relatively wet early October, the weather over much of the area turned warmer and drier during the second half of October and into November. A strong ridge of high pressure over the […]
