Travelling at least 4,000 miles to reach Florida, Saharan dust is expected to reach and impact the weather across the Sunshine State. Worsening air quality could occur too.

Frequent storms, heavy rains and intense heat have been the pattern across the Florida Peninsula in the last several days - with the heat starting very early in the morning and reaching as high as 99 degrees with added humidity making it feel much hotter.

A change of pace is ahead for Florida with the arrival of Saharan dust this week. This dusty Saharan air layer has already affected the eastern and central Caribbean this week, triggering heat alerts across much of Puerto Rico.

Once the dust reaches South Florida, the risk of showers will decrease starting Wednesday. Gradually, on Thursday and Friday, central and northern Florida will also see the arrival of the dust.

Dust also poses other issues, such as respiratory problems for people with pre-existing conditions. You can take us along on vacation and check the Air Quality Index for your destination—anywhere in the world! If your eyes are watering or itching... blame the dust!

Saharan dust supplies a large amount of nutrients to forest and marine ecosystems. It also contains significant amounts of iron, which marine microorganisms—such as algae—can use as a food source. As these organisms multiply, they can become toxic, triggering red tide blooms. Our team of meteorologists will continue to provide you with updates.
