Cyclone Melissa is projected to escalate to a rare category five cyclone as it veers towards Jamaica, bringing life-threatening sudden floods and rock falls.
The hurricane, which recorded winds of up to 120 mph as of 0600 Greenwich Mean Time, is currently turning north-west in the Caribbean region and is expected to hit the coast by Tuesday, according to meteorological authorities.
Warnings of power cuts and disruption to utilities have been announced as Melissa generates up to thirty inches of rain and sea level surges as high as 13ft above ground. "Take cover without delay," inhabitants have been told.
The cyclone is the 13th cyclone in the current Atlantic season, which normally finishes in the eleventh month.
A Category 5 hurricane is the most intense classification, with sustained winds of at least 157 miles per hour.
Although Melissa is projected to reduce in intensity to a fourth-level cyclone before making landfall on the island, authorities said there was "minimal real distinction in the general consequences" upon making contact with land, and that the storm will be "equally strong" when it impacts the nation.
With tropical storm-level wind and rainfall predicted to begin long before it moves across central Jamaica - including potentially the capital, Kingston - warnings emphasize that "preparations should be rushed to completion".
"Several days of damaging winds and torrential rain have begun and will cause catastrophic and life-threatening sudden floods and numerous landslides," counseled weather authorities.
The country's head of government the official stated: "I know that there are numerous residents who are worried, who are extremely apprehensive, and with good reason: concern is justified.
"But the optimal approach to handle anxiety and any unease and worry is to stay ready."
Residents are being instructed to secure their homes with sand barriers and timber panels, and to gather essentials.
Alerts are also ongoing for regions of the neighboring country such as the capital, Port au Prince, the Dominican Republic and eastern Cuba, where the hurricane is expected to bring similar effects by the middle of next week.
Landslides presently generated by the storm have already killed two in the country, according to local authorities.
Melissa is predicted to move across Cuba by the middle of the week before moving through the Antillas Mayores and entering the open ocean.
By the time it makes contact with Cuba, it is anticipated to have reduced to a Category 3 cyclone.
While it is hard to associate individual weather events to environmental shifts, experts say it is causing weather phenomena increasingly frequent and more intense.
Warmer oceans create greater water vapor in the air, helping fuel the development of hurricanes.
Before the start of this season's Caribbean cyclone season, weather organizations projected above-normal activity, mentioning elevated ocean temperatures and possible more intense weather patterns around African coastal regions - where Atlantic storms often form.
