Tropics Impact: Here’s when the First Saharan Dust Plume Is Set to Arrive in Central Florida
- A vast Saharan dust plume about 2,000 miles wide is forecast to reach Florida, Louisiana, Alabama, and Mississippi this week and weekend.
- The dust originates from the Sahara Desert, carried westward by waves of low pressure grouped into the Saharan Air Layer, active mainly in June and July.
- The dust currently causes hazy skies and respiratory issues in the Caribbean and may create hazy air and vivid sunsets in Florida as it arrives midweek.
- Experts say most dust remains high , limiting health risks, though rain can deposit dry dust residue, while wildfire smoke in Florida moderately affects air quality.
- This Saharan dust inhibits tropical storm formation by stabilizing the atmosphere, allowing forecasters to better predict storms during the expected above-average 2025 hurricane season.
