In the south, crews are building a guard west of the Tommy Lakes Road, and employing direct attack on the southeast flank. On the southwest flank, they are also installing sprinklers on the South Nig Road guard in preparation for possible controlled ignitions. MacAuley said that while the fire did cross the CN Rail tracks along its southeast edge, crews have found that the rail line itself was undamaged in the fire. She said that firefighters are also working to protect any backup rail ties that may be sitting along the tracks.The weather forecast is currently calling for cooler temperatures for the rest of the week, with a chance of showers and a risk of thunderstorms on Wednesday. MacAuley explained that crews are welcoming the cooler temperatures and precipitation, but that thunderstorms could cause increased fire activity due to the presence of strong wind gusts near convective clouds.
