Spot weather or site specific forecasts may be obtained by Fire Control Agencies upon request to the National Weather Service in Caribou, ME. Spot forecasts for wildfires and other emergency situations (i.e. affecting life or property) are available 24 hours a day/7 days a week, and can be provided to any federal, state or local agency.
The Spot requests should be made via our online spot request form - http://spot.nws.noaa.gov/cgi-bin/spot/spotmon?site=car
Spot forecasts for prescribed burns are also available at any time. The National Weather Service will provide spot forecasts for prescribed burns according to the following criteria:
1. Upon request of any federal official who represents that the spot forecast is required under the terms of the Interagency Agreement for Meteorological Services (See: http://www.nws.noaa.gov/directives/sym/pd01004001e112004curr.pdf).
2. Upon request of any state, tribal, or local official who represents that the spot forecast is required to carry out their wildland fire management responsibilities in coordination with any federal land management agency participating in the Interagency Agreement for Meteorological Services.
3. Upon request of any public safety official who represents the spot forecast is essential to public safety, e.g. due to the proximity of population centers or critical infrastructure. A "public safety official" is an employee or contract agent of a government agency at any level (federal, state, local, tribal, etc.) charged with protecting the public from hazards including wildland fires of whatever origin and/or other hazards influenced by weather conditions such as hazardous material releases.
The National Weather Service does not provide spot forecasts to private citizens or commercial entities not acting as an agent of a government agency.
Keep in mind that the response time for spot forecasts in support of prescribed burns may vary depending on higher priority duties of the forecaster on duty. This is especially true during non routine work hours (i.e. those hours other than Monday-Friday 800 am to 400 pm), and during weekends when staffing is minimal.
On site weather observations are necessary for issuance of a spot weather forecast. Minimum requirements for a weather observation include the dry bulb temperature, the relative humidity, and the surface wind speed and direction.
If those elements are unavailable, and the forecaster feels that will negatively impact the forecast, he/she may decline to fulfill a formal spot forecast request.
All wind measurements are assumed to be at eye level using a hand held wind instrument. If wind measurements are taken from a tower, this should be noted and relayed to the forecaster. Please use the Spot Forecast Request Form as guidance for information to supply to the fire weather forecaster.
For very large fires (involving thousands of acres), observations should be obtained, if possible from several points around the fire. This will enable the forecaster to better gauge the effects of the fire on local weather patterns.
For prescribed burns, a weather observation from the site should be taken and sent to the forecaster about two hours before ignition. Location of the fire site must also be included with the spot forecast. Latitude and longitude along with a nearby major feature (topographic, town, etc.) is best.
The fire weather user requesting the spot forecast should also provide the following information: Location, Size of burn, Elevation, and Fuel (vegetation) type (e.g. is it a stand of dense pines or perhaps a grassy field?)
The National Weather Service forecaster should ask what weather elements are desired and most important to the burn. The forecaster should also inquire about the time period for the spot forecast. The first 12 hours of the burn time should have the most detail in it.
Remember to provide a phone number or fax number in order for the spot forecast information to reach the proper location.
If weather conditions develop that were not forecasted and threaten the success of the operations at the fire, the forecaster should be notified immediately. Furthermore, any feedback concerning the accuracy of the spot weather forecast (both positive and negative) will assist the forecaster in subsequent forecasts for the same or similar location.
