Isaac Poses a Threat to the Lesser Antilles This Week

11 Sep 2018, 8:57 am

Tropical Storm Isaac continues to move westward in the Atlantic Ocean and poses a significant threat to the Leeward and Windward Islands. On Monday, the cyclone was downgraded to a Tropical Storm with 70 mph winds. Isaac’s winds are now down to 65 mph.

The center of Isaac is located about 580 miles east of the Lesser Antilles. On the current forecast track, Isaac should move across the Lesser Antilles and into the eastern Caribbean Sea Thursday into Friday.  Isaac is expected to produce 2 to 4 inches of rain with isolated amounts near 6 inches, along with strong winds and a storm surge of several feet.

Forecast models have come into better agreement on a westward path of Isaac, moving around the south side of a strong high pressure ridge to the north. The cyclone will likely encounter some upper level wind shear, but it is expected to be modest.
