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.

The times presented here are based upon the solunar theory, which is the idea that the movements of fish and other animals are affected by the location of the sun and moon. The major periods are believed to be the times of the greatest animal activity and occur when the moon is directly overhead or underfoot (lunar transits). The minor periods also see increased activity and occur when the moon is rising or setting. The strongest activity occurs during full or new moons, and the weakest during quarter or three quarter moons. This is indicated by the Action Rating.
