Cayman urged to watch Tropical Storm Isaac as path waivers

Tropical-storm-force winds extend outward up to 160 miles from the center.

Subtropical Storm Joyce is located 945 miles west-southwest of the Azores and is moving to the southwest at 6 mph (9 km/h).

Isaac's death knell was sounded around 5 a.m. Saturday when the National Hurricane Center's aircraft was unable to find a well-defined center and as a result the center reported that the storm had "dissipated".

A Storm Surge Watch means there is a possibility of life- threatening inundation, from rising water moving inland from the coastline, in the indicated locations during the next 48 hours. If the rain bands persist, the National Weather Service may raise the flash flood watch to a flash flood warning triggering the emergency alert system. Regardless of the exact path, Florence will be a large system, and impacts such as heavy rain and strong winds will extend well beyond the center and at least into southeast SC. Isaac has maximum sustained winds of 45mph with higher gusts, and officials at Hazard Management Cayman Islands are urging people to keep an eye on the storm's path because it could be heading our way.

Before that, however, it was Tropical Storm Olivia, a system that was expected to bring pounding rains and flooding to Oahu and Maui. This rainfall may cause unsafe flash flooding.

Tropical Storm Warnings are now in effect for Martinique, Dominica and Guadeloupe. Current estimates have Isaac passing nearly 150 miles south of St. Croix early Friday morning.

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. It, too, has been weakening and is now a tropical depression.

Steered westward by high pressure to its north, Isaac is forecast to move through the Lesser Antilles today and tomorrow. Along the coast, large waves will accompany the surge.
