The Cayman Islands National Weather Service continues to monitor a strong tropical wave which has entered the Caribbean Sea, along a path that could see it travel south of the Cayman Islands within the next five days.

In a ‘potential severe weather’ notification issued shortly after 8:30am today, the CINWS cautioned residents that, while there is still a “degree of uncertainty” around the actual storm path, there is a strong chance the islands will still be impacted by the passing storm.

“The system is likely to become a tropical depression as it moves into an area more favourable for development,” stated the CINWS, referring to the US-based National Hurricane Center’s five-day forecast.

According to the NHC, the system has a 70% chance of developing into a tropical storm between today and Saturday and a 90% chance by Monday of next week.

If the system does strengthen, as it has in the past week, it is likely to become Tropical Storm Hermine, the eighth named storm of the 2022 Atlantic hurricane season, which began on 1 June and ends 30 Nov.

“Regardless of development of the system, the latest forecast information indicates there is a high potential for this system to impact the Cayman Islands early next week,” warned the CINSW.

“Scattered thunderstorms, rough seas and gusty winds are likely from late night on Sunday as the disturbance moves over the western Caribbean,” it forecast.

The CINWS added, “There still remains some uncertainty as to where the disturbance will move as it gets to the western Caribbean and as such residents are urged to keep abreast of the updates on this system.”

Further east, the Atlantic hurricane basin is seeing other storm activity, as NHC forecasters are monitoring Hurricane Fiona, Tropical Storm Gaston, and two other tropical waves, one in the central Atlantic Ocean and the other just off the western coast of Africa.

These storms pose no immediate threat to the Cayman Islands.
