A combination of very warm temperatures, low relative humidity in the 20s (percent), and dry fine fuels and leaf litter will create an elevated risk of wildfire spread today across portions of Western Pennsylvania south of Interstate 80. The period of greatest potential for wildfire spread will be between 11 am and 7 pm today. Residents are urged to exercise caution if handling any potential ignition sources, such as machinery, cigarettes, or matches. If dry grasses and tree litter begin to burn, the fire will have the potential to spread rapidly.
