Tropical Storm #Isaac – #Invest96L – August 22 2012

Isaac still a Tropical Storm at this hour ‘expected to become a Hurricane within the next 48 hours’. Currently located at 15.5North 57.3West about 280 Miles East of Guadeloupe, with winds of 45mph and is heading West at 18mph. The central pressure is 1003mb or 29.62inches. Isaac is showing better organization on satellite imagery and beginning to get the classic look of tropical systems. Isaac has an eye as reported by Hurricane Hunters currently investigating with a diameter of 10 nautical miles [ 12 statute miles ].

Outer rainbands are currently impacting the Leeward and northern Windward Islands. Isaac will impact the Leeward Islands Today. Some strengthening may occur before landfall. Tropical Storm winds which extend outward 45 miles form the center of Isaac will be felt before the center makes landfall. Rainfall amounts of 1 to 8 inches are expected in some areas before Isaac crosses and makes his way into the Western Caribbean Thursday morning.

* A ‘Hurricane Watch’ is in effect for Puerto Rico, Vieques, Culebra, and the U.S. Virgin Islands, the South Coast of the Dominican Republic from Isla Saona Westward to the Haiti Dominican Republic Southern Border.

* A Tropical Storm ‘Warning’ is in effect for Martinique, Dominica, Guadeloupe and St. Martin and surrounding Islands as well as St. Kits, Nevis, Antigua, Barbuda, Montserrat, Anguilla, Saba, St. Eustatius, St. Maarten, the British Virgin Islands, Puerto Rico, Vieques, Culebra, and the U.S. Virgin Islands.

* A tropical Storm ‘Watch’ is in effect for the North Coast of the Dominican Republic from Haiti Dominican Republic Northern Border Eastward to North of Isla Saona.

* Interest in and around these areas including Hispaniola and Cuba should be monitoring the progress of Isaac.
* I urge interest in Florida, the Eastern Gulf coastal areas and the East coast to remain vigilante as the forecast track of Isaac remains uncertain at this time.

I continue to watch [Invest 96L] in the East Atlantic about 650 Miles West-Southwest of the Cape Verde Islands. This wave has winds last reported of 30mph and is located at 11.5North 34.5West moving to the West-Northwest. As of 2:00 AM EDT 96L has a 90 percent chance of becoming our next depression or storm ‘later today’. Once named it will be Joyce. The forecast track at this time remains uncertain. Next update from NHC on this system 8:00 AM EDT

I’ll be keeping a close watch on both of these systems in the days to come.
