Saharan Dust Blankets Florida, Stifles Tropics

As of July 28, 2026, Florida is experiencing extreme heat, with millions of residents under heat warnings and advisories. Temperatures in parts of the Panhandle and Big Bend are projected to reach 94-100°F, with heat indices potentially hitting 115°F. This intense heat comes as a significant Saharan dust plume is anticipated to arrive by the end of the week and into the weekend.

The Saharan dust is expected to increase in concentration late this weekend into early next week. This phenomenon, common in early August, will contribute to hazy sunshine and enhanced sunsets. Crucially, forecasters indicate this dust will help maintain quiet conditions in the main tropical cyclone development region for at least 10 days, with no disturbances currently listed by the National Hurricane Center.

Despite the current lull in tropical activity, the Atlantic hurricane season, which runs from June 1 to November 30, is approaching its peak on September 10. The busiest period typically falls between mid-August and mid-October. In the Pacific, Hurricane Genevieve remains a powerful Category 4 storm with 140-mph winds, though steady weakening is forecast. Tropical Storm Fausto is expected to pass north of the Hawaiian Islands, bringing significant surf.

Looking ahead, a stalled cold front is predicted to bring daily downpours to northern Florida from Wednesday, July 29, through Sunday, August 2. Some areas could receive 2-4 inches of rain, with locally up to 6 inches, potentially leading to flash flooding due to dry soil conditions.
