Q: What is the Fujiwhara effect observed between Hurricanes Humberto and Imelda?

The Fujiwhara effect is a rare phenomenon where two tropical systems interact and orbit each other, like a spinning teacup ride or ballroom dancers. In late September 2025, the centers of Hurricanes Humberto and Imelda came within 465 miles of each other, the closest such pairing in the Atlantic since 1966.

Q: What areas are most at risk for additional storms in the coming weeks?

Summary

Satellite imagery shows Hurricanes Humberto and Imelda off US East Coast
Forecasts indicate more storms to come in the final two months of 2025 season
Rare Fujiwhara effect observed between Humberto and Imelda in late September

As of October 2, 2025, satellite imagery has captured Hurricanes Humberto and Imelda churning just off the coast of the Eastern United States. With four months already passed, the 2025 Atlantic hurricane season still has two full months remaining, and forecasters warn that more storms are likely to develop.

Just a day after advisories ended on Hurricane Humberto, two new potential storm systems have already appeared on the National Hurricane Center's radar. Experts at Colorado State University predict "slightly above-normal activity" in the coming weeks, citing indications of possible development in the central tropical Atlantic and the northwest Caribbean/Gulf region.

One notable event this season was the rare "Fujiwhara effect" observed between Hurricanes Humberto and Imelda in late September. This phenomenon occurs when two tropical systems interact, causing them to orbit each other. The centers of Humberto and Imelda came within 465 miles of each other, the closest such pairing in the Atlantic since 1966.

Despite a quiet start, the 2025 hurricane season has already seen three major hurricanes, matching the minimum number predicted by forecasters. With the potential for more storms on the horizon, the final two months of the season could prove to be quite active.
