Active Atlantic Hurricane Season: Two Tropical Systems Developing and Forecast Uncertainty
The 2025 Atlantic hurricane season is intensifying as two tropical systems, Invest 93L and Invest 94L, are likely to develop this week. Invest 94L, near the northeastern Caribbean, could become a tropical depression or storm as it approaches the Bahamas or Southeast US Coast, with potential to impact Florida, the Virgin Islands, Puerto Rico, and possibly Bermuda. Its future path is uncertain due to complex atmospheric patterns, interaction with nearby systems, and possible engagement in the Fujiwhara effect, where two storms rotate around each other. Meanwhile, Invest 93L, located east of the Leeward Islands, may develop into a hurricane and pose a threat to Bermuda early next week. The forecast for these systems remains highly uncertain, with models showing a wide range of possible tracks, including offshore movement, landfall in the US, or impact on Bermuda. Heavy rain, flooding, and dangerous surf conditions are expected along the US East Coast, the Bahamas, and Bermuda. The season, which has been slower than average with only seven named storms and two hurricanes so far, is now entering its more active late-season phase, with typical formation zones shifting closer to land in the Gulf, Caribbean, and western Atlantic. Forecasters warn that the Atlantic weather pattern is highly complex and unpredictable, with the possibility of multiple interactions, including the Fujiwhara effect, which could alter storm paths. Overall, the season remains unpredictable, with late-season storms still capable of causing significant impacts.
