Special Weather Statement issued March 29 at 2:01AM EDT by NWS Baltimore MD/Washington DC
Effective: Sun March 29, 2026, 2:01 AM
Expires: Sun March 29, 2026, 8:00 PM
The combination of drying fine fuels, relative humidities around 20 to 30 percent, and wind gusts around 20 to 25 mph will lead to an increased risk for the rapid spread of wildfires today. Following modest early morning relative humidity recovery, the conditions most conducive to fire spread are expected from late morning through early evening (roughly 10 AM to 8 PM EDT). 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.

There is an elevated risk for fire spread today for the Eastern Shore of Maryland. Minimum relative humidity values will fall to around 30 percent. This will be accompanied by southwest winds around 15 to 20 MPH with gusts up to 25 MPH. These conditions, along with the continuing drying of fine fuels, could support the rapid spread of any fires that ignite, which could quickly become difficult to control. Conditions improve close to sunset as winds decrease and RHs increase. 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.
