N.H.C. said at 5:00 p.m. that the center of Tropical Storm Isaac was located near latitude 14.9 North, longitude 63.2 West. Isaac is moving toward the west near 16 miles per hour (26 km/h), and this general motion with a decrease in forward speed is expected for the next few days.

Tropical storm warnings were issued for Martinique, Dominica, and Guadeloupe. Effective at 8 p.m. Tuesday, the Coast Guard Sector San Juan captain of the port set port condition X-ray for the USVI and Puerto Rico due to the expectation of sustained gale force winds of 25 mph and gusts up to 40 mph generated by tropical storm Isaac that may arrive within 48 hours.

Some slight strengthening is possible during the next couple of days. On Thursday morning, South 17th Street, usually teeming with commuter traffic by 6:30 a.m., was almost devoid of cars.

While now classified as a hurricane, Helene will be downgraded to a storm by the time it reaches the shores of Northern Ireland.

No coastal watches or warnings are in effect, and the NHC forecast track shows the storm heading west towards Central America.

In an update on Thursday, September 13, 2018, the Met Office said the centre of Tropical Storm Isaac passed through the northern Lesser Antilles at approximately 9:00 am Thursday and was passing over the eastern Caribbean Sea. A Category 4 hurricane at its strongest, Olivia spent about a week swishing around in the Pacific Ocean without making landfall before it weakened into a tropical storm. It is expected to continue on a westward path toward the islands.

Bridges, airports and ferry services in the affected areas face closure if winds grow too violent, while roads and rail routes might also be cut off. It should dissipate by early next week, the hurricane center said. "There will be some rain but at the moment it doesn't look as though that's going to be the issue". On Wednesday, officials said some of those shelters were at capacity, but in a statement early Thursday, county officials said they were "able to mobilize additional resources to accommodate the need for shelter space".

Tropical Storm Watches were also discontinued for St. Maarten, St. Martin, Saba and Eustatius.

"A broad area of low pressure is located over the central Gulf of Mexico". A hurricane hunter plane is scheduled to investigate the system Thursday.
