Special Weather Statement issued November 6 at 9:05AM EST by NWS Mount Holly NJ

Effective: Thu November 6, 2025, 9:05 AM
Expires: Thu November 6, 2025, 6:00 PM

There is an elevated risk for fire spread today for Delaware, the Eastern Shore of Maryland and eastern Pennsylvania. Minimum relative humidity values will fall into the 30-40% range. This will be accompanied by cool and dry northwest winds of 10 to 15 mph with gusts up to 20 to 30 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. Relative humidities will begin to increase late in the afternoon as winds will decrease toward sunset. 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.
