WINSTON-SALEM, N.C. —
Humberto is forecast to strengthen over the open Atlantic as it follows a path similar to Gabrielle. The system is forecast to become a Category 3 hurricane status on a west-northwest track that may coincide with another tropical system that may become Imelda. The twin tropical systems may interact with one another and change storm intensities as well as tracks as they approach the Southeast U.S. coast.
East Coast impacts are likely by next week
There is a lot of uncertainty about whether these two tropical systems in the Atlantic will get close enough to the U.S. coast to bring major tropical impacts, but coastal impacts from big waves and rip currents are already developing. The storms are projected to move between the North Carolina coast and Bermuda. The steering currents aloft favor keeping the storms offshore from Bermuda and the U.S., but the system that becomes Imelda may ride close to the Gulf stream and influence Humberto’s journey too over the Atlantic.

Imelda may form soon and move near Humberto in Atlantic
The second tropical area of concern will bring heavy rain and storms to Puerto Rico and the Dominican Republic in the Caribbean before it drifts into the Atlantic to strengthen into the next named system, Imelda.

Gabrielle continues to bring threats to the Azores, and remnants from the storm may wrap back toward Portugal and slide south toward Northern African.
Areas to Watch in the Tropics
Over the next few weeks, the WXII 12 First Warning Weather Team will be focused on three main areas for tropical development:
The Gulf: Very warm sea surface temperatures can help fledgling storms explode into monster hurricanes quickly under the right atmospheric conditions.Africa: In late summer, waves of low pressure often move from the Sahara Desert into the eastern Atlantic. They can develop into tropical systems over time. The sub-tropical high-pressure system over the Atlantic will often steer these systems through the tropical Atlantic towards Central America and the United States.Southeast U.S. Coast: Weaker, short-lived storms often form in late summer or fall along the old frontal boundaries. Areas of offshore low pressure can become tropical. These storms can become dangerous quickly because they are so close to the coast.
Are you prepared for inland tropical impacts in North Carolina and Virginia?
September and October are historically the busiest tropical months for the Carolinas. The 2025 Atlantic hurricane season continues through Nov. 30.
