Expect a very warm - okay, make that hot - week with lots of sun, not much rain.

South Florida's Monday forecast calls for mostly sunny skies with afternoon highs in the upper 80s and overnight readings in the low 70s.

Central Florida's forecast: Mostly sunny with highs in the low 90s, lows in the upper 60s and a 20 percent chance of rain.

This week is national Air Quality Awareness Week. Southeast Florida is one of the least likely metropolitan areas in the country to suffer from air pollution.

We have little in the way of heavy industry and usually fresh ocean breezes preclude the build up of particulate matter and ozone.

However, on parts of three days this April, the air quality here has been in the "moderate" rather than the "good" range. The two most recent days were on Friday and Saturday.

Winds for the past week have been unusually light, averaging less than 8 mph each day. This means that there is little mixing of the air, and thus pollution can concentrate more readily.

Why have we had the light winds at a time when it is normally quite breezy? Large areas of low pressure have been moving off of the U.S. mid Atlantic coast recently which weakens the Bermuda High, and thus slackens our winds.

For the most part, this same pattern will persist for the next week or two before the Bermuda High strengthens and the trade winds blow more consistently.

Other sources of air pollution here include smoke from wildfires, Saharan dust, and when pollution from other elsewhere such as the northeast U.S. or Mexico invade the area.

Reducing vehicle emissions is the most effective way of reducing pollution here. Instead of going through the drive-thru, park and go inside.
