Thunderstorms came through the park starting July 1, and remained active through July 11. Yosemite National Park has 9 lightning-caused fires. These kinds of fires can take days or weeks to detect because vegetation has to dry out enough to create smoke or visible flames after the storm passes over. Additional fires may be discovered, as temperatures remain warm and fuels dry out.
Most of these fires are small;single tree strikes that amount to less than a tenth of an acre. These fires are in the wilderness and are being monitored by either fire crews hiking into the fire areas or via air reconnaissance due to location, sparse fuels, and low growth potential. Yosemite and Point Reyes fire crews are monitoring all fires.
