Officials with northern Minnesota's Superior National Forest say they saw a flare-up of fire activity on Sunday as low humidity and gusty winds combined with the ongoing drought created dangerous fire conditions. Authorities reported Sunday evening that the Phantom Creek and Bear Creek fires about 10 miles west of Ely "are getting some suppression action due to increased fire behavior.” "Expect to see several aircraft dipping out of Lake Vermilion and making water drops on both fires to slow movement so personnel on the ground can take action," the Forest Service reported. Officials said any boaters out on the lake who see firefighting aircraft at work should move to shore. The Phantom Creek fire was sparked by lightning as storms moved through the area late Friday and early Saturday. As of Sunday morning it was about an acre in size.
