A new tropical storm could form in the Atlantic this week and continue the 2025 hurricane season’s backloaded burst of tropical activity. Even though fewer storms tend to form now, in the late-season, history has shown how devastating they can be, particularly since development areas shift closer to land.

The tropical wave in the central Caribbean will be upgraded to Tropical Storm Melissa later Tuesday, and more and more storm models suggest a forecast track that hooks north through the islands.

National Hurricane System forecasters say there's an 80% chance of tropical depression formation within 48 hours and a 90% chance within 7 days.
