Stats and Events
Current Year Statistics
The below statistics are tracked on a weekly basis and provide a snapshot of the number of fires and acres burned. These are preliminary numbers taken from our Computer Aided Dispatch (CAD) system and the national Incident Management Situation Report, and will likely change as dispatched wildfires may end up being other types of fires, false alarms or as more accurate information is provided. These numbers are subject to change until the final fire season reports are completed and tabulated.
