Hurricane Nigel still brings the strongest winds in the Atlantic Ocean, but the two other systems have more potential for affecting United States and Caribbean life over the next week.

Here’s the latest updates on Hurricane Nigel and the disturbances from the National Hurricane Center.

Hurricane Nigel is weaker but faster

As Hurricane Nigel makes a northeast swing away from North America, now about 495 miles southeast of Cape Race, Newfoundland, its maximum sustained winds are down to 85 mph. But Nigel is making that northeast move at a swift 30 mph and is expected to continue in that direction through Thursday. Hurricane force winds can be felt 60 mph from Nigel’s and tropical storm force winds up to 150 miles from its center.

“Weakening is forecast during the next couple of days, and Nigel is forecast to become a post-tropical cyclone by Friday,” the 4 a.m. Thursday hurricane center advisory said.

Hurricane Nigel is still causing swells that cause rip currents and perilous surf in Bermuda. But the storm isn’t close enough to land for any watches or warnings.

A disorganized disturbance near Florida

What the hurricane center describes as “a large area of disorganized showers and thunderstorms” off Florida’s east coast threatens to become something more serious. Whether it does or not, it will affect weather for the east coast of the United States.

“A non-tropical low pressure system is expected to form within this area by early Friday, and this system could acquire some subtropical characteristics on Friday or early Saturday while it moves generally northward toward the coast of North Carolina,” the hurricane center’s 8 a.m. advisory said. “Regardless of development, this low is likely to bring gusty winds to gale force, heavy rain, and high surf to portions of the Southeast and Mid-Atlantic United States late this week and into this weekend.”

Formation chance through 48 hours: 30%.

Formation chance through seven days: 40%.

A wave in the Eastern Atlantic Ocean

A tropical wave near the Cabo Verde Islands is expected to “merge with another disturbance located a few hundred miles to its west in a few days,” the hurricane center said, as it moves west at 10 to 15 mph.

Expect a tropical depression to form by Sunday.

Formation chance through 48 hours: 20%.

Formation chance through seven days: 70%.
