Far below normal precipitation has caused a drought and increased fire danger levels. All of Connecticut is currently in a Stage 2 Drought Advisory. Residents are encouraged to be mindful of water consumption and use extra caution to prevent fires. An emergency burn ban remains in effect at all state parks, forests, and wildlife management areas, prohibiting the use of all outdoor grills, firepits, campfires, etc.

Emergency Burn Ban In Effect 10/26/24 - An emergency burn ban is now in effect for all Connecticut State Parks, Forests, and Wildlife Management areas, prohibiting the use of all outdoor grills, firepits, and campfires, and the kindling and use of flame outdoors. DEEP and local agencies are working to contain several active fires across the state. Please avoid all affected State Parks and Forests, as well as the blue-blazed Mattabesett Trail. The Enduro Trail in Voluntown and portions of North Stonington within the Pachaug State Forest are closed at this time. Please note that today's forest fire danger report remains at an 'extreme' level. More information about the current fire danger, burn ban and recommended safety measures can be found here

Section 169A of the Clean Air Act makes it a national goal to prevent further deterioration and to remedy any existing visibility impairment due to man-made pollution in areas designated mandatory Class I federal areas. Class I areas are federal areas, such as national parks and wilderness areas, designated to have important value regarding visibility. These areas are listed in 40 CFR 81 Subpart D. While there are no Class I areas in Connecticut, haze is a regional problem and all States are obliged to assist in meeting the goal of attaining natural visibility in Class I areas by 2064. Connecticut fulfills its obligations by updating its implementation plan every ten years. Progress in meeting goals is assessed every five years and documented separately when not coinciding with a ten-year plan revision.
