Impacts From Storms Go Well Beyond The Cone

Tropical Storm Lorenzo became the 12th storm of the 2025 Atlantic hurricane season early Monday morning, October 13, 2025. That's about right on the average pace for the arrival of the "L" storm, according to the National Hurricane Center.

The storm formed deep in the Atlantic from a tropical wave coming off of Africa. The Bermuda High's prevailing steering pattern of the season kept the storm's track far away from land, and significant wind shear and dry air kept Lorenzo weak, despite relatively warm ocean temperatures.

In the weeks leading up to Lorenzo, there was an uptick in tropical activity for the Atlantic, putting the basin back roughly on track for the Atlantic season, though no hurricanes for the season as of yet had impacted the U.S. mainland.
