Special Weather Statement issued April 11 at 3:53AM EDT by NWS Mount Holly NJ
Effective: Sat April 11, 2026, 3:53 AM
Expires: Sat April 11, 2026, 8:00 PM
There is an elevated risk for fire spread today across southeastern Pennsylvania. Minimum relative humidity values will drop to around 25 to 35 percent this afternoon. This will be accompanied by northwesterly winds with gusts up to 20-25 MPH. These conditions, along with the continued drying of fine fuels, could support the rapid spread of any fires that ignite, which could quickly become difficult to control. Conditions improve during the evening as the wind diminishes and the relative humidity increases. Outdoor burning is strongly discouraged. Be sure to properly extinguish or dispose of any potential ignition sources, including smoking materials such as cigarette butts. This forecast considers meteorological, fuel, and land conditions and has been developed in coordination with state fire officials.

Special Weather Statement issued April 11 at 6:59AM EDT by NWS State College PA

Expires: Sat April 11, 2026, 7:00 PM
The combination of drying fine fuels and leaf litter, low relative humidity of 25 to 35 percent and a moderately gusty northwest wind of 15 to 20 mph, 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.
