Smoke from Colorado wildfires drifting over Iowa

Smoke from wildfires raging in Colorado has drifted into Iowa, making for redder skies at dawn and dusk but causing no health problems.

The Des Moines Register says the smoke will likely remain over the state until the fires are out. The National Weather Service says the smoke is high in the atmosphere, so residents likely won't see too many effects.

Meteorologist Kevin Skow says winds, which generally flow from west to east across the U.S., has pushed the smoke over Iowa. He says the sky is hazier, and sunrises and sunsets will be redder than normal.

Meteorologists haven't notices any dust or other particles that could settle on the state and aren't aware of any health risks. Environmental officials say Iowa's air quality is good.
