A Storm starts as a Tropical Depression and moves on to become a Tropical Storm before it is given a name. Once a storm is named, preparations for the possible hurricane should be well under way.

NOAA’s forecast for the 2025 Atlantic hurricane season—which runs from June 1 to November 30—indicates a 60% chance of an above-normal season, a 30% chance of a near-normal season, and a 10% chance of a below-normal season.
The agency predicts 13 to 19 named storms (with winds of at least 39 mph), of which 6 to 10 could become hurricanes (winds of 74 mph or more). Among those, 3 to 5 are expected to strengthen into major hurricanes (Category 3 or higher, with winds of 111 mph or greater). NOAA expresses 70% confidence in these projections.
The 2025 hurricane season is expected to be above normal, driven by a combination of factors that favor tropical storm development. These include ongoing ENSO-neutral conditions, above-average ocean temperatures, forecasts of weak wind shear, and the potential for increased activity from the West African Monsoon—a key source of Atlantic storm formation. The Atlantic Basin remains in an era of heightened hurricane activity, marked by elevated ocean heat content and weaker trade winds. The warmer waters provide more energy to fuel storms, while reduced wind shear allows systems to strengthen with less interference. Additionally, this season may see a northward shift in the West African Monsoon, which could lead to more frequent and intense tropical waves—often the precursors to the strongest and longest-lived Atlantic hurricanes.
