Special Weather Statement issued April 12 at 4:55AM EDT by NWS State College PA
Effective: Sun April 12, 2026, 4:55 AM
Expires: Sun April 12, 2026, 6:00 PM
The combination of drying fine fuels and leaf litter, low relative humidity of around 35 percent and a southerly wind gusting between 20 and 25 mph during the late morning and afternoon hours, will create an elevated risk of wildfire spread across the southern half of Pennsylvania 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. For more information about wildfire danger and wildfire prevention and education, please visit the Pennsylvania Department of Conservation and Natural Resources website at http://dcnr.pa.gov/Communities/Wildfire.
