What happened to Invest 91L? On Saturday, the tropical wave that was thought to become a tropical depression and then Tropical Storm Gabrielle, was disrupted by Saharan dust, dry air, and wind shear, and ripped apart.

It dissipated – and no tropical activity is expected for at least the next seven days, according to the National Hurricane Center. It comes as the climatological “peak” of the 2025 Atlantic hurricane season nears – Sept. 10 – despite the hurricane season lasting until Nov. 30, 2025.

It is too soon to tell what the impacts to Florida will be, if any. This is a future outlook and a lot could change in the days and weeks ahead. The FOX 35 Storm Team will continue to monitor any changes.
