Critical Fire Weather Conditions

Fire weather, which is rated from low to moderate and critical, pertains to weather and climatic conditions that are favorable for fire growth and smoke dispersion. According to the NWS, fire weather is used by meteorologists. It also considers soil moisture and relative humidity as ingredients for potential wildfires. In most cases, fire weather alerts are issued before and during the eruption of wildland fires.

The US Government weather agency explains that red flag warnings or fire weather watches are issued when a combination of dry fuels and weather conditions favors the eruption of fires. For instance, wildland fires such as bushfires and forest fires can be triggered by at least one or two of these fire weather conditions.

California Wildfire Statistics

As mentioned earlier, California is no stranger to wildland fires since it is also part of the Western US region where drought conditions are persistent. In 2020, massive California wildfires resulted in the deaths of 33 people after a series of blazes engulfed a total land area of more than 1.7 million hectares, according to local authorities.

This year alone, there have been a total of 2,731 California wildfires recorded as of July 1, as reported by the California Department of Forestry and Fire Protection, which also monitors fire incidents caused by humans, in addition to fire weather-triggered wildland fires.
