A Red Flag Warning means that critical fire weather conditions are expected throughout a certain timeframe. Residents are advised to exercise extreme caution during a Red Flag Warning because a simple spark could cause a major wildfire, including the use of equipment and machinery as well as smoking.
Weather and climate play major roles in the development and spread of wildfires. Of the three major components making up a fire's environment (Fuel, Weather, and Topography), weather is the most important, and it is continuously changing. Weather elements that play the largest role in wildfires are:
- Relative Humidity/Atmospheric Moisture
- In addition drought, a result of certain weather conditions and climate, must be considered.
