Strong gusts forecast in B.C. and wind set to change direction, creating new challenges for wildfire crews

Winds are expected to shift direction and gusts could reach up to40 km/h in parts ofthe southern Interior and 50-70 km/h in the southeast,creating potentially dangerous situations for fire crews battling wildfires.

Wind speed and direction have dramatically affected the wildfire situation in B.C. over the past two days, and Thursday evening'sforecast shows it will continue to play a major role in fire behaviour.

The B.C. Wildfire Service has issued a wind advisory for the province'sInterior, southern Interior and southeast regions that extends to Thursday night.

"Wind activity may significantly impact fire growth in these regions," the advisory says."The rate of fire spread will likely increase, and the direction of fire growth may change quickly on some wildfires."

Winds are expected to shift direction into Thursday night, and gusts could reach up to40 km/h in parts ofthe southern Interiorand 50-70 km/h in the southeast. This would create potentially dangerous situations for firefighting as the heads of the fires shift and wind speeds cause fires to spread and fuel to become even drier.

The wind will likely calm on Friday, but could return over the weekend.

Nearly3,400 square kilometres of land have already been burned by wildfire since April 1.

Wind conditions feeding fires

Fire ecologist Robert Graysaid wind essentially feeds wildfires, which means Thursday will be a challenging day for firefighters.

"The fuels are already dry," he said."So we will see quite significant spread rates, long range spotting and very, very dangerous conditions."

Though fires tend to burn uphill, Gray said wind could influence the fire to move downhill.

The "heat dome" that blanketed much of Western Canada in late June and early July, raising temperatures to record levels, prompted the start of the wildfire season about a month early, Gray said.

"We're going to see things change year after year after year, trending to the worse situation," he said.

"We're also going to see more of these exceptional events like what we saw in July with the heat dome and those trigger tipping points that occur sooner down the line. We're going to see things constantly changing and, unfortunately, changing for the worse."

Fire information officer Noelle Kekulasaid they're always watching the weather todetermine what might happen with wildfires.

Wind tore through the Interior yesterday, causingthe Lytton Creek fire to spread north. This prompted a new evacuation alert for 94 propertiesnorth of Lytton,which was destroyedby wildfire on June 30.

"We of course have our crews on it," she said.

An incident management team has been on site since July 1, and 42 firefighters and four helicopters are fighting that fire.
