Though the center of both storms are well offshore, a pair of hurricanes will still bring dangerous conditions to beaches along the East Coast into early October, forecasters said as they credited a rare scientific phenomenon with helping steer the worst of the danger out to sea.

The core of Imelda will miss the U.S. coast thanks to high pressure and Hurricane Humberto, but the new hurricane will still trigger dangerous surf, rip currents, and coastal flooding from Florida to the Northeast.

Hurricane Humberto's swells will probably cause "life-threatening surf and rip current conditions," the National Hurricane Center warned.

Swells generated by Imelda and nearby Hurricane Humberto have been affecting the Bahamas, and are spreading to much of the East Coast.

Swells and high surf from both Tropical Storm Imelda and Hurricane Humberto are expected to bring dangerous marine conditions and rip currents along much of Florida and the East Coast of the United States during the next several days. ➤ Weather alerts via text: Sign up to get updates about current storms and weather events by location

Hurricane Humberto, a Category 2 storm, is not expected to make landfall in the U.S., but the East Coast could still see some impacts.

Potential Tropical Cyclone Nine is expected to become a tropical storm over the weekend, prompting tropical storm warnings for the Bahamas. According to FOX 13 meteorologist Nash Rhodes, the system should parallel the east coast of Florida before possibly making landfall early next week.
