The current battle against wildfires in Nova Scotia has led to the displacement of 21,000 people and is expected to reach a critical stage today. Fire officials are concerned about a phenomenon known as “crossover,” which could result in a resurgence of two major fires. Temperatures are expected to rise above 30°C, humidity levels are expected to dip below 30%, and wind speeds may exceed 30 km/h. The two primary fires that remain uncontained, one in the suburbs of Halifax and the other in the southwestern part of the province, have already destroyed over 200 homes and cottages. Firefighters are contending with dry conditions, increasing temperatures, and rising wind speeds, resulting in a hazardous environment for wildfires. Nova Scotia Premier Tim Houston has requested assistance from Prime Minister Justin Trudeau, including water bombers, helicopters, and firefighting foam, as well as the establishment of a base camp for 250 firefighters. Environment Canada has issued warnings about poor air quality in Shelburne County. Nova Scotia has experienced 201 wildfires this season, with 28 occurring in the last week, burning 190 square kilometers of land. Cooler temperatures and consistent rainfall are expected to arrive late Friday.
