Isaac makes headway toward Caribbean Sea, but still unlikely to affect Mexico

Cancun, Riviera Maya, Q.R. — With one tropical system leaving the area, state civil protection reports that although tropical storm Isaac continues to move toward the Caribbean, it still does not pose a threat to Mexican land.

The once category 1 hurricane lost its status and returned to a tropical storm Tuesday, however, the small storm is still packing a punch with reported wind gusts nearing 95 km/h (60 mph). According to National Oceanic and Atmospheric Administration, the center of Tropical Storm Isaac is moving toward the west at 26 km/h.

Isaac is forecast to continue on his path westward into the Caribbean Sea where he will move across the central Lesser Antilles on Thursday before entering the Caribbean. Although small, his tropical-storm-force winds extend outward up to 165 kilometers from the center with maximum sustained winds of 95 km/, which are expected to decrease over the coming days.

While passing land, Isaac is expected to bring tropical storm conditions and heavy rainfall of between 2 and 4 inches to Martinique, Dominica and Guadeloupe with up to one inch across the remaining Windward and Leeward Islands.

Some coastal flooding and large sea swells are expected as Isaac passes the Lesser Antilles this afternoon.

According to NASA’s Aqua satellite, the circulation of tropical storm Isaac is displaced, indicating the storm could weaken. According to the National Hurricane Center, “Satellite images indicate that the strong tropical storm still has a central dense overcast pattern and a limited amount of outer bands [of thunderstorms].

“Earlier microwave data indicated that the center was not located in the middle of the convection, however, likely due to some westerly [wind] shear.”

Isaac is still forecast for Caribbean waters by Thursday. In anticipation of his arrival, a tropical storm warning has been put into effect for Martinique, Dominica and Guadeloupe, while a tropical storm watch is in effect for Antigua, Montserrat, St. Kitts and Nevis and Saba and St. Eustatius.

According to Servicio Meteorológico Nacional for Mexico, as of 5:00 a.m. Wednesday, due to its distance, tropical storm Isaac does not represent any risk for the national coasts, however, its evolution will continue to be monitored.
