Officials say combination of high temperatures and stiff breezes could lead to ‘extreme fire behaviour’ in Maritime province
Officials in the Canadian province of Nova Scotia say a day of blistering heat, strong winds and low humidity could lead to “extreme fire behaviour” as they work to control wildfires that have forced more than 20,000 people from their homes.
Fire crews said on Thursday they were concerned about a phenomenon known as “crossover”, which occurs when temperature rises above 30C, humidity drops below 30% and winds exceed 30km/h.
