SALT LAKE CITY (AP) -- Overcast skies and high humidity kept lightning-sparked wildfires that have burned for days in southern Utah from significantly advancing Monday.
The fire has blackened about 16,000 acres, but no communities were immediately in danger, said Bureau of Land Management spokesman David Boyd.
Three helicopters and more than 300 firefighters were battling the Square Complex fire about 14 miles north of St. George, Boyd said.
Boyd said the fire was 20 percent contained, and officials expected it to be fully contained by July 4.
That all depends on how the weather cooperates with efforts, he said.
``It really didn't put up much smoke today, but it still could,'' Boyd said. ``It still has the potential to make more advances.''
