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]
A 230 hectare fire spawned on Vancouver Island on July 22, 5 km south of Sooke Lake. The fire was held, but required 70 firefighters and three helicopters and forced the precautionary closure of nearby Sooke Potholes Regional Park. [43] [44] On July 28, BC Wildfire Services reported 372 fires, classifying 177 as out of control. [45]
Wildland fire behavior is affected by weather, fuel characteristics, and topography.. Weather influences fire through wind and moisture. Wind increases the fire spread in the wind direction, higher temperature makes the fire burn faster, while higher relative humidity, and precipitation (rain or snow) may slow it down or extinguish it altogether.
The California Climate Information System, or CalCIS, would have made California the first state to create an open-source, continually refreshed climate hub.
Later in September, fire activity again decreased due to improved fire weather. [8] While numerous storms in Northern California significantly slowed fire activity in November and December, dry conditions and multiple rounds of Santa Ana Winds led to multiple wildfires in Southern California, such as the Mountain and Franklin fires.
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 ...
Hot and dry weather is fueling wildfire activity in the Western United States and Canada, with fires damaging homes, causing injuries and forcing evacuations. The largest active wildfire in the US ...
The North American Ensemble Forecast System (NAEFS) is a joint project involving the Meteorological Service of Canada (MSC) in Canada, the National Weather Service (NWS) in the United States, and the National Meteorological Service of Mexico (NMSM) in Mexico providing numerical weather prediction ensemble guidance for the 1- to 16-day forecast period.
