Isaac has been upgraded to a hurricane with winds of 75 mph. Isaac is is forecasted to become a 100 mph storm as it approaches the Lesser Antilles later this week. Once the hurricane reaches the eastern Caribbean, it is expected to weaken back to a tropical storm due to forecasted unfavorable conditions. We will watch this system closely as it progresses westward. Interests in the eastern Caribbean should follow the forecast for Isaac closely.
