Disturbance in the Caribbean Sea
Published 18th August 2020, 2:10pm
Hazard Management Cayman Islands (HMCI) and the Cayman Islands National Weather Service (CINWS) are monitoring a tropical wave over the eastern Caribbean Sea. The National Hurricane Center (NHC) is advising that the disturbance is producing an area of disorganized thunderstorms and gusty winds.
The wave is moving westward at about 20 mph and significant development is unlikely during the next day or two, but after that time, the wave is forecast to slow down, and a tropical depression is expected to form late this week when it reaches the northwestern Caribbean Sea. The NHC gives the disturbance a 70 percent chance of formation over the next five days.
Current models have the system passing south of the Cayman Islands and the threat to the Cayman Islands (from this system) is considered to be very low. Despite the low probability of any significant impacts to the Cayman Islands from this disturbance, residents are encouraged to monitor the progress of this wave as it tracks generally westward across the Caribbean Sea.
As we enter the traditionally more active part of the hurricane season, residents are encouraged to increase levels of preparedness. Overhanging trees (that could bring down wires or fall on buildings) should be trimmed back. Window coverings such as plywood sheets or shutters are important to minimize the likelihood of wind entering the home and lifting the roof. Stocks of non-perishable food and water to last three to seven days should be stored, and items like a flashlight and a radio should form part of residents' preparedness kits.
The most important aspect of preparing for a hurricane is establishing where you will go to safely get through the impact phase. If you are not sure your home is safe from powerful winds, large waves and storm surge then it is critical to have an alternative shelter plan.
