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.

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.
