MIAMI (AP) -- South Florida's smoky skies are clearing a bit, even though a wildfire in Everglades National Park continues to grow.

A dense smoke advisory was canceled after wind conditions improved visibility for drivers in Broward, Palm Beach and Miami-Dade counties. But officials are still advising children, the elderly and people with breathing problems to stay indoors.

The fire was burning almost 40,000 acres of Everglades National Park and is 30 percent contained.

It had been at 36,000 acres yesterday. Officials hope rising humidity will slow its spread.

The wildfire also was burning in the only known habitat for the endangered Cape Sable seaside sparrow. Water flow was increased to the area, and state officials say the birds appeared to be safe.
