What primary factor should be considered for accurate fire behavior forecasts?

Current weather conditions are crucial for making accurate fire behavior forecasts because they directly influence how fires ignite, spread, and behave. Key weather factors include temperature, humidity, wind speed and direction, and precipitation. For example, warm temperatures and low humidity can exacerbate fire conditions, while high winds can increase the rate at which a fire spreads, making it more difficult to control. Additionally, changes in weather throughout the day can lead to unpredictable fire behavior, which is why real-time monitoring of conditions is essential for effective fire management and response strategies.

While adjacent property values can impact resource allocation and cloud cover may affect visibility, they do not have as immediate or significant an effect on fire behavior as current weather conditions do. Similarly, while the time of year impacts seasonal fire trends, it is the specific, real-time weather conditions that ultimately determine fire dynamics in a given situation.
