TALLAHASSEE, Fla. (AP) _ Hot temperatures and low winds have led to a severe pollution problem in Florida, prompting state officials to warn everyone to avoid strenuous outdoor activities during the day.

The weather has exacerbated the ozone problem _ pollution created from the exhaust of cars, lawn mowers, boats and other engines _ by forcing it close to the ground, said Elsa Bishop, a state environment administrator.

``This goes from tip to tip of Florida,'' said Bishop, with the state Department of Environmental Protection.

The air is worst in South Florida and the Tampa Bay area, with the most danger between 11 a.m. and 7 p.m.

Asthmatics, children and elderly people should stay inside as much as possible. Healthy adults can still walk to lunch, go to the beach or visit theme parks.

The ozone pollution is unrelated to the fires in Mexico, Bishop said.
