MELROSE, Fla. -- State officials say the first sizable brush fire of the winter season has burned more than 300 acres near the border of Putnam and Alachua counties.

Forestry officials say the fire, which was first spotted Friday evening near Melrose, was considered 100 percent contained but not completely out.

Affecting mostly grasslands, crews from the Division of Forestry and nearby fire departments have been working to keep the fire from spreading.

Officials said heavy rains Sunday should help keep the fire under control, but dry conditions over the next week could cause smoldering parts of the swampy area to flare up again.

No structures were threatened or damaged by the fire.

A smaller fire burning in Flagler County did threaten homes, forcing the evacuation of a few families near U.S. Highway 1 in Palm Coast.

The fire was estimated to cover 35 hours on Saturday. It was reduced to 10 acres by late Sunday.
