La Niña doesn’t just shape winter weather. When it develops during hurricane season, it can boost both the number and strength of storms in the Atlantic — and may influence the second half of the 2025 season.

Atlantic hurricane season began June 1 and runs through Nov. 30. This year, both Colorado State University and the National Oceanic and Atmospheric Administration (NOAA) are predicting an above-average season.

A disturbance forming off the southeastern U.S. coast may become the first storm of the 2025 Atlantic hurricane season. The National Hurricane Center posted an alert on Monday evening, warning of a "non-tropical area of low pressure" forecast to form within the next few days.
