|Weather is one of the most significant factors in determining the potential and severity of wildfires. The spread rate and intensity of fires are directly related to the wind speed, temperature, and relative humidity. Also, climatic conditions such as long-term drought play a major role in the number and intensity of wildfires. Accurate and timely weather information is vital to planning for wildfire suppression. A core mission of the National Weather Service is to provide daily fire weather forecasts to federal and state land management agencies. In addition, specialized and detailed forecasts are provided, when needed, to aid in managing wildfires and conducting prescribed burns. Unfortunately, one of the leading causes of wildfires is arson. Approximately half the acres burned by wildfires in is due to fires set intentially by arsonists. The thoughtless acts of arsonists not only damage forests, watersheds, and wildlife habitats, but they also pose a direct threat to you and your property. Help fire and law enforcement authorities catch arsonists by providing information. Simple tips often pay off during an investigation. Call the arson hotline at 1-800-762-3017.
