Vermont Fire Danger

Vermont is divided up into 5 Fire Danger Rating Areas (FDRA). A Fire Danger Rating Area is a geographic area relatively similar in climate, fuels and topography, within which the fire danger can be assumed to be uniform. Its size and shape is based on influences of fire danger, not political boundaries. Click here for a List of Towns in Each Fire Danger Rating Area. Wildland fire danger ratings are determined by comparing forest fuel conditions, recent weather conditions, and various fire start risk factors. During non-snow periods of the year, the Department of Forests, Parks and Recreation monitors forest fire danger levels daily. Fire danger in Vermont is calculated based on the National Fire Danger Rating System (NFDRS). Input into the NFDRS model comes from weather observations from five remote automated weather stations (RAWS) Understanding Fire Danger: Green (Low) A green rating indicates that the fire danger potential in an area is low. This means that fires are unlikely to start, but if they do, weather and fuel conditions will make it difficult for them to spread quickly. As such, any fires should be low in intensity and easy to control. Blue (Moderate) A blue rating indicates that fire danger potential is moderate. This means that there is potential for fires to start from common accidental causes, but fire incidents are still relatively rare. Fires that do start in these areas are moderate in intensity, flame length, and rate of spread. However, control is still typically not difficult and requires light to moderate clean-up. Yellow (High) A high fire danger rating is indicated by the color yellow. These fires present high potential for danger, and fires can easily start in fine fuels like grass, needles, and debris. Fires in dry fields and leaf litter are difficult to control, particularly in windy conditions. Outdoor burning should be avoided when possible. Orange (Very High) Orange signifies a very high fire danger rating, and fires in these areas start easily from all causes, often spreading faster than suppression resources can be delivered. Flame lengths are typically long and high in intensity. Controlling these fires is very difficult. Outdoor burning is not recommended in orange rated areas. Red (Extreme) Extreme fire danger is indicated by the color red. Fires in these areas start very easily, burn intensely, and spread rapidly. Small fires typically grow at a very fast rate. These fires are very difficult to control, often last for several days, and can become very dangerous. No outdoor burning should take place in areas with a red fire danger rating.佛蒙特州共划分为5个火灾危险评级区域（Fire Danger Rating Areas, FDRA）。 火灾危险评级区域是指气候、可燃物与地形特征相对均一的地理区域，该区域内的火灾危险程度可视为统一。其范围与形状依据火灾危险影响因素划定，而非行政边界。 点击此处查看各火灾危险评级区域下辖城镇清单。 野外火灾危险评级通过比对森林可燃物状况、近期气象条件及各类起火风险因子确定。在每年非降雪时段，佛蒙特州森林、公园与娱乐管理局会每日监测森林火灾危险等级。 该州的火灾危险计算基于国家火灾危险评级系统（National Fire Danger Rating System, NFDRS），该模型的输入数据来自5个远程自动气象站（Remote Automated Weather Stations, RAWS）的气象观测值。 火灾危险等级说明： 绿色（低危险）：绿色评级代表区域内火灾危险潜力较低。此时火灾较难引燃，即便发生，受气象与可燃物条件限制，火势也难以快速蔓延。因此火灾烈度通常较低，且易于控制。 蓝色（中等危险）：蓝色评级表示火灾危险潜力处于中等水平。常见意外诱因具备引发火灾的可能性，但火灾事件仍相对罕见。在此区域引燃的火灾烈度、火焰长度及蔓延速度均处于中等程度，扑救难度通常不高，仅需开展轻度至中度的清理作业即可。 黄色（高危险）：黄色代表高火灾危险评级。此类区域的火灾极易在细可燃物（如青草、针叶与碎屑）中引燃，干燥田地与落叶层中的火势难以控制，在大风天气下尤为如此。建议尽可能避免户外焚烧作业。 橙色（极高危险）：橙色代表极高火灾危险评级。该区域内火灾可由各类诱因轻易引燃，且蔓延速度往往超过扑救力量的驰援效率。火焰长度通常较长、烈度较高，扑救难度极大。橙色评级区域内不建议开展户外焚烧作业。 红色（极端危险）：红色代表极端火灾危险评级。该区域内火灾极易引燃，燃烧烈度极高且蔓延迅速，小型火情也会快速发展。此类火灾极难控制，通常会持续数日且极具危险性。红色评级区域内严禁开展任何户外焚烧作业。
