Yosemite National Park fire and aviation crews have responded to multiple lightning-caused wildfires located within the park boundary.
Lightning-caused wildfires are a common occurrence. There have been a total of 10 lightning-caused wildfires since July 31, 2017. One fire currently in monitor status is the Empire Wildfire. Which is currently being managed for resource and protection objectives.
Monitoring a wildfire is a fire management tactic used by fire managers when strategizing an incident response, and contributing factors that help steer this decision-making process are often incident specific. Location, available resources, predicted weather, topography, air quality and predicted fire behavior are all factors that contribute to fire management decisions.
