Generating Hourly Weather Forecasts
You can derive 6 days of hourly weather forecast for an incident's latitude and longitude, or for any point you select on any map display in WFDSS. A local National Weather Service (NWS) Forecast Office provides the hourly forecast data, often referred to as point forecast data, for the 2.5km grid cell that contains the selected point. Inconsistency among point forecasts and associated elements may occur due to variation in forecast development and display among Forecast Offices.
Hourly weather forecasts become important when a fire's origin is at an elevation that varies significantly from the active portion of a fire, and when the fire is being modeled. In this case, hourly weather forecast data at the fire's origin would not reflect conditions on the actively burning portion of the fire, and a different more representative location (and grid cell) might provide more suitable forecast information. For example, if a fire's origin is at 7000' elevation and you are modeling fire behavior for an active portion of the fire at 9000', select a point on the map with an elevation around 9000'.
Contact your local NWS Forecast office you have questions regarding the hourly weather forecasts.
To Generate Hourly Weather Forecasts:
- From a map display in WFDSS, click the Info tab.
- Choose one of the following options to generate an hourly weather forecast:
- For an incident's recorded latitude and longitude, select Hourly Weather Forecast.
- For a different location, select the
tool from the toolbar above the map, and then left click once on the area of the map you would like to generate an hourly weather forecast for. Select Hourly Weather Forecast.
- A pop-up window from a local NWS Forecast Office appears with hourly forecast information. Select Weather, Precipitation, and Fire Weather elements, as needed and as available, to modify the display.
