Special Weather Statement issued April 16 at 3:33AM EDT by NWS Baltimore MD/Washington DC

Effective: Thu April 16, 2026, 3:33 AM
Expires: Thu April 16, 2026, 8:00 PM

The combination of 10 hour fuel moistures around 9 percent, relative humidities around 25 percent, and wind gusts of 20 to 25 mph will lead to an increased risk for the rapid spread of wildfires this afternoon. Residents and visitors are urged to properly dispose of cigarette butts, matches, and any other flammable items in appropriate containers. Additionally, exercise caution if operating any equipment that could create sparks and keep vehicles off of dry grass. Most dry grasses, dead leaves, and other tree litter could easily ignite and spread fire quickly. Lastly, remember to obey local burn bans. For more information about wildfire danger, burn restrictions, and wildfire prevention and education, please visit your state forestry or environmental protection website.

Special Weather Statement issued April 16 at 4:45AM EDT by NWS Mount Holly NJ

Effective: Thu April 16, 2026, 4:45 AM
Expires: Thu April 16, 2026, 8:00 PM

There is an elevated risk for fire spread today across southeastern Pennsylvania and Delmarva. Minimum relative humidity values will drop to around 25 to 35 percent this afternoon. This will be accompanied by temperatures rising into the mid 80s to low 90s and southwesterly winds near 10 to 15 mph, with gusts up to 20 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. Use caution while using any machinery outdoors, such as lawn care equipment, that could cause sparks to come in contact with the dry ground. 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.
