Key Points

Our Forecast
Kirk has not shown any signs of strengthening over the past several hours. The system will barely hang on to its tropical storm status over the next 24 hours. Some mid-level dry air entrainment and an acceleration in its forward speed will likely weaken Kirk to a tropical depression by Monday morning. When Kirk begins slowing down Tuesday night into Wednesday, it could regain tropical storm strength as it approaches the Windward Islands. However, increasing wind shear across the eastern Caribbean will likely lead to weakening and dissipation north of Venezuela next Friday or Saturday. There is currently no model support for Kirk reaching the Gulf of Mexico or the southeast U.S. Coast.

Our next advisory will be issued by 10 AM AST / 9 AM 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.
