Cal Fire said it made only slight improvements in its fire models between the old and new local responsibility maps, including using more detailed and up-to-date climate data and calculating ...
Los Angeles and other areas in California are among the highest-risk areas for wildfires — but they're not the only ones. Many fires take place in areas where humans have overstepped into nature ...
Burning Index (BI) is a number used by the National Oceanic and Atmospheric Administration (NOAA) to describe the potential amount of effort needed to contain a single fire in a particular fuel type within a rating area. The National Fire Danger Rating System (NFDRS) uses a modified version of Bryam's equation for flame length – based on the ...
NFDRS is a complex set of equations with user-defined constants and measured variables to calculate the daily index and components that can be used for decision support. [3] A Fire Danger Rating level takes into account current and antecedent weather, fuel types, and live and dead fuel moisture. [5]
A fire danger index of between 12 and 25 on the index is generally considered a "high" degree of danger, while a day having a danger index of over 50 is considered a "severe" fire danger rating. Above this level in 2010 a distinction was made between forest and grassland fuels.

As of Wednesday morning, the most recent update from the New Jersey Forest Fire Service says that the fire has burned 2,283 acres in New Jersey, about 3,500 overall, and is 30% contained. Wildfire ...
The concept has important practical use in fire safety engineering. For instance, to safely fill a new container or a pressure vessel with flammable gases, the atmosphere of normal air (containing 20.9 volume percent of oxygen) in the vessel would first be flushed (purged) with nitrogen or another non-flammable inert gas, thereby reducing the ...
