Special Weather Statement
Special Weather Statement issued April 7 at 8:37AM EDT by NWS Baltimore MD/Washington DC
Apr 7, 8:37 AM
→ Apr 7, 7:00 PM
The combination of drying 10 hour fuels, minimum relative
humidity around 15 to 30 percent, and northwesterly wind gusts
around 20 to 35 mph will lead to an increased risk for the rapid
spread of wildfires today, especially in the afternoon to early
evening.
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.
