Daily Fire Weather Index forecast. The Forest fire weather index (FWI) (French: indice forêt météo, IFM) is an estimation of the risk of wildfire computed by Météo France and the Meteorological Service of Canada. It was introduced in France in 1992 but is based on a Canadian empirical model developed and widely used since 1976. [1]
Forest-fire models have been developed since 1940 to the present, but a lot of chemical and thermodynamic questions related to fire behaviour are still to be resolved. Scientists and their forest fire models from 1940 till 2003 are listed in article. [6] Models can be divided into three groups: Empirical, Semi-empirical, and Physically based.
The fire eventually consumed over 32,000 hectares and destroyed 358 of Jasper's 1,113 structures. [23] [24] Smoke from the fire combined with that from Park Fire in California and reduced air quality as far as New England and Mexico [25] The Jasper fire continued to grow through August along its southern border.

The ensemble variant of the GEM is known as the Global Ensemble Prediction System (GEPS). It has 20 members (plus control) and runs out 16 days, the same range as the American global forecast system. The GEPS runs alongside the GFS ensemble to form the North American Ensemble Forecast System. A regional ensemble prediction system (REPS ...
False-color view of the burned area and smoke from the Park Fire in Northern California, viewed from the Landsat 9 satellite on July 27, 2024. By the end of spring (June 20), the total area burned by wildfires in California was nearly 90,000 acres (36,000 ha).
The risk of fatal fires that stem from burning slash can also be reduced by proactively reducing ground fuels before they can create a fuel ladder and begin an active crown fire. Predictions show thinned forests lead to a reduction in fire intensity and flame lengths of forest fires compared to untouched or fire-proofed areas. [45]
CMC building viewed from the West CMC building viewed from the South. The Canadian Meteorological Centre (CMC; French: Centre météorologique canadien), located in Dorval, Quebec, is the branch of Environment Canada's Meteorological Service of Canada that is tasked with providing forecast guidance to national and regional prediction centres, and is responsible for running the Global ...
An extremely critical fire weather event is the greatest threat level issued by the NWS Storm Prediction Center (SPC) for wildfire events in the United States. On the scale from one to three, an extremely critical is a level three; thus, these outlooks are issued only when forecasters at the SPC are confident of extremely dangerous wildfire ...
