MIAMI, USA — Disorganized cloudiness and thunderstorms over the western Caribbean Sea associated with a trough of low pressure is producing heavy rainfall over portions of Central America and is expected to produce locally heavy rainfall over the Cayman Islands, Jamaica, and portions of Cuba during the next day or two.
These rains are forecast to spread northward over the northwestern Bahamas on Saturday night and Sunday.
According to the National Hurricane Center in Miami, environmental conditions are expected to be conducive for some development on Friday and Saturday as the system moves slowly northward over the northwestern Caribbean Sea. Strong upper-level winds associated with an approaching cold front will make conditions less favourable by Sunday.
The chances of a tropical cyclone forming through 48 hours are estimated to be low (30 percent) and medium (40 percent) during the next five days.
