Thousands of residents in the British Columbia communities of Summerland and Peachland have been chased out of their homes by an explosive wildfire that sprang up Friday. Here is the latest on the wildfire that forced 20,000 to flee:8 a.m. PTThe BC Wildfire Service says airtankers worked to drop retardant along the fires eastern flank as it tried to slow the spread and protect structures. But the wind fanned the flames, carrying embers up to a kilometre ahead of the main body of the fire. The service said the fire behaviour became volatile and eventually compromised both the safety and efficiency of the tankers’ objectives.
