Hurricane Helene: All you need to know about storm

Saint Lucia was spared the effects of heavy rainfall associated with Tropical Storm Isaac which was expected to produce 50 mm - 100 mm on the island from September 12 - 14, 2018.

The National Hurricane Center now maintains a 60 percent chance of development for a disturbance entering the southern Gulf of Mexico within 5 days. "These enormous waves are produced by being trapped along with very strong winds moving in the same direction as the storm's motion", the branch wrote on Twitter. Tropical-storm-force winds (39 miles per hour or higher) are expected to arrive on Martinique, Dominica and Guadeloupe by early Thursday.

Little change in strength is expected over the next several hours as Isaac moves through the Leeward Islands.

Meanwhile, Isaac is a tropical storm that will eventually die out as it moves closer to the Yucatán Peninsula, according to Bridges.

For its part, the tropical storm Helene, located southwest of the Portuguese Azores, has tilted its course to the north and must be maintained with a similar course and speed of translation over the waters of the eastern Atlantic. This rainfall may cause unsafe flash flooding.

Tropical Storm Isaac made its closest approach to St. Croix Thursday night, passing nearly 200 miles to the south and having no apparent impact on the territory as it made its leisurely way across the Caribbean.

The National Hurricane Center said in its 11 a.m. ET advisory that up to 5 inches of rain could fall in Puerto Rico.

Tropical Storm Watches were also discontinued for St. Maarten, St. Martin, Saba and Eustatius. The government of France has discontinued the Tropical Storm Watch for St. Martin, and the government of St. Maarten has discontinued the Tropical Storm Watch for St. Maarten. Damaging winds, floods, high surf and storm surge are still possible. These swells are likely to cause life-threatening surf and rip current conditions.
