Possible Sub-Tropical Cyclone Near Bahamas/Gulf Stream


A weak surface trough over the Bahamas and Cuba is interacting with an upper level trough over the Gulf of Mexico. Over the next 3 – 5 days there is potential for the surface and upper level systems to align in such a way that allows the surface trough to organize and sustain deep convection and become a sub-tropical cyclone.

The area of troughiness is currently moving northwards into the southwest Atlantic. Over the next 3 – 5 days, the trough and its associated convection are expected to then track northwestward – towards the South Carolina coast. An area of convergence to the far east of this trough/sub-tropical cyclone could bring scattered shower activity to Bermuda in 3 – 5 days as a weak cold front approaches the island from the north.

In the meantime, fair weather is expected in Bermuda for the next 2-3 days. Overall, little if any noticeable impact to Bermuda is currently expected from this disturbance.

For the latest updates see the National Hurricane Center, and see the Bermuda Weather Service for official forecasts for Bermuda.
