1. Kirk may weaken to a depression as it reaches the Windward Islands on Thursday.
2. The primary impact on the islands will be from heavy rainfall.
Tropical Storm Kirk continues moving steadily westward toward the eastern Caribbean this morning. An overnight wind satellite pass did find a closed circulation with winds to 45 mph to the northeast of the center. As Kirk passes north of Barbados on Thursday morning, it will be encountering increasingly strong westerly wind shear, which should lead to steady weakening to a tropical depression as it passes north of St. Lucia on Thursday evening. Even stronger wind shear in the eastern Caribbean should lead to the dissipation of Kirk on Friday. The primary threat to the central Lesser Antilles will be from potentially heavy rainfall as Kirk passes on Thursday.
Expected Impacts on Land
Windward Islands: Localized flooding may occur due to heavy rains. Any power outages are likely to be isolated in nature.
Puerto Rico: What is left of Kirk may enhance shower and thunderstorm activity for Puerto Rico on Friday. Widespread significant impacts are not expected. However, locally heavy rainfall is possible.
Our next advisory will be issued by 4 PM AST / 3 PM CDT

The yellow cone represents track error from the previous five hurricane seasons. Over the past five hurricane seasons, the center of the storm tracked within the yellow cone 75% of the time. The cone does not represent the forecast uncertainty in the current advisory for this storm. In addition, hurricane-force winds, very high tides, large waves, and heavy rainfall can often extend well outside the yellow cone.
