The weekend classification, for both Saturday and Sunday, is posted Saturday morning. You do not need to have a Twitter account to access this information. Fire Danger is a description of the combination of both constant and variable factors that affect the initiation, spread, and difficulty to control a wildfire within a specific area. There are many systems and models that attempt to provide accurate and reliable predictions of fire danger. Typically, the effects of fuel conditions, topography, and weather conditions are analyzed and integrated into a set of numbers that fire managers can use to meet their needs.

Based on the fire danger, managers may impose restrictions or closures to public lands, plan for or pre-position staff and equipment to fight new fires, and decide whether to suppress or allow fires to burn under prescribed conditions. Sincefive rating levels have been used to describe danger levels in public information releases and fire prevention signage:. Low Green - Fire starts are unlikely.

Weather and fuel conditions will lead to slow fire spread, low intensity and relatively easy control with light mop-up. Controlled burns can usually be executed with reasonable safety. Moderate Blue - Some wildfires may be expected. Expect moderate flame length and rate of spread. Control is usually not difficult and light to moderate mop-up can be expected. Although controlled burning can be done without creating a hazard, routine caution should be taken. High Yellow - Wildfires are likely.

Understanding Fire Danger

Fires in heavy, continuous fuel such as mature grassland, weed fields and forest litter, will be difficult to control under windy conditions. Control through direct attack may be difficult but possible and mop-up will be required. Outdoor burning should be restricted to early morning and late evening hours. Very High Orange - Fires start easily from all causes and may spread faster than suppression resources can travel. Flame lengths will be long with high intensity, making control very difficult.

Both suppression and mop-up will require an extended and very thorough effort. Outdoor burning is not recommended. Extreme Red - Fires will start and spread rapidly. Every fire start has the potential to become large. Expect extreme, erratic fire behavior.Preparedness Levels are dictated by fuel and weather conditions, fire activity, and resource availability. The five Preparedness Levels range from 1 to 5, with 5 being the highest level. Each Preparedness Level has specific management directions.

As the Preparedness Levels rise, more federal and state employees become available for fire mobilization if needed. Geographic Areas accomplish incident management objectives utilizing local resources with little or no national support. Active Geographic Areas GA's are unable to independently accomplish incident management objectives. Resource capability remains stable enough nationally to sustain incident operations and meet objectives in active GA's.

Mobilization of resources nationally is required to sustain incident management operations in the active Geographic Areas GA's.

National priorities established as a necessary measure to address the heavy and persistent demand for shared resources among active GA's.

Shared resources are heavily committed. National mobilization trends affect all Geographic Areas GA's and regularly occur over larger and larger distances. National priorities govern resources of all types. National mobilization is heavily committed and measures need to be taken to support GA's. Active GA's must take emergency measures to sustain incident operations. Preparedness Level 1 Geographic Areas accomplish incident management objectives utilizing local resources with little or no national support.

Preparedness Level 2 Active Geographic Areas GA's are unable to independently accomplish incident management objectives. Preparedness Level 3 Mobilization of resources nationally is required to sustain incident management operations in the active Geographic Areas GA's.

Preparedness Level 4 Shared resources are heavily committed. Preparedness Level 5 National mobilization is heavily committed and measures need to be taken to support GA's.Especially where and when fuel dryness data does not exist. Southwest area LIS graphic.

University of Washington hosts an experimental surface water monitor page. This includes graphics of snow water equivalent, soil moisture, total moisture storage and cumulative runoff.

The drier soil moisture areas brown, orange and red correlate fairly well to higher wildland fire activity and drought conditions short and long term.

The bureau works with forest fire wardens and volunteer fire departments to promote the latest advances in fire prevention and suppression. Pennsylvania wildland firefighters also assist with wildfire suppression efforts throughout the nation. Certain conditions are necessary for a wildfire to occur:. The first two factors occur most frequently in Pennsylvania during spring and autumn.

As the spring sun climbs higher in the sky, days become longer and warmer. The trees are bare during this time, allowing sunlight to reach the forest floor, warming the ground, and drying surface fuels. Coupled with strong and dry spring winds, this leads to a tremendous amount of combustible fuels. During autumn, leaves turn color and begin to fall, accumulating in a deep, fluffy layer that creates a fire hazard.

Find out the current fire danger rating in your area and other information about fire weather. The BC Wildfire Service operates about weather stations, which send reports on an hourly basis.

With it, fire managers can assess the potential for ignition, spread and burning intensity. This information is used for making fire prevention, preparedness and suppression decisions, as well as other general fire management decisions.

Temperature, relative humidity, precipitation, wind speed and wind direction are recorded by the fully automated stations. This data is transmitted to BC Wildfire Service headquarters every hour from April through October, but less frequently and from fewer stations during the winter months. The fire danger rating i. Carry out any forest activities with caution. New fires may start easily, burn vigorously, and challenge fire suppression efforts.

Extreme caution must be used in any forest activities. Open burning and industrial activities may be restricted. New fires will start easily, spread rapidly, and challenge fire suppression efforts.

General forest activities may be restricted, including open burning, industrial activities and campfires. For regulated forest operations, the danger class value must be derived from weather data representative of the site on which operations are being conducted. A detailed danger class report provides estimated and forecast fire danger rating values for specific weather stations.

Expect extreme, erratic fire behavior. Relative humidity RH is the ratio of the amount of moisture in the air to the amount of moisture necessary to saturate the air at the same temperature and pressure. Relative humidity is expressed in percent. RH is measured directly by automated weather stations or manually by wet and dry bulb readings taken with a psychrometer and applying the National Weather Service psychrometric tables applicable to the elevations where the reading were taken.

Relative humidity is important because dead forest fuels and the air are always exchanging moisture. Low humidity takes moisture from the fuels, and fuels in turn, take moisture from the air when the humidity is high.

Light fuels, such as grass and pine needles, gain and lose moisture quickly with changes in relative humidity. When the RH drops, fire behavior increases because these fine fuels become drier.

Heavy fuels, on the other hand, respond to humidity changes more slowly.Idaho Fire Incident Map.
