A combination of warm temperatures in the mid to upper 70s, low relative humidity in the 35 to 45 percent range, dry fine fuels and leaf litter, and a moderately gusty southerly breeze in the teens will create an elevated risk of wildfire spread today across a portion of South Central Pennsylvania and the Susquehanna Valley. 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.
