Cyclone Melissa is predicted to strengthen into a rare category five storm as it veers towards Jamaica, delivering life-threatening sudden floods and landslides.
This weather system, which recorded winds of up to 120 mph as of 6:00 AM GMT, is now shifting north-west in the Caribbean Sea and is anticipated to make landfall by midweek, as reported by weather experts.
Warnings of power cuts and disruption to utilities have been released as the hurricane brings up to 30 inches of rain and coastal flooding as high as thirteen feet above ground. "Take cover without delay," residents have been told.
Melissa is the 13th named hurricane in this year's Atlantic hurricane season, which normally finishes in the eleventh month.
A Category 5 hurricane is the strongest type, with wind speeds of at least 252 km/h.
While the hurricane is projected to weaken to a fourth-level cyclone before arriving at Jamaica, meteorologists said there was "minimal real distinction in the overall impacts" upon landfall, and that the storm will be "equally strong" when it hits the island.
With storm-force gusts and precipitation already expected well before it passes over Jamaica's central region - perhaps encompassing the national capital - advisories state that "readiness efforts must be accelerated".
"An extended timeframe of destructive gusts and intense precipitation are underway and will cause catastrophic and life-threatening rapid water accumulation and many mudslides," advised meteorological officials.
Jamaican Prime Minister Andrew Holness said: "I know that there are many Jamaicans who are concerned, who are deeply troubled, and rightfully so: concern is justified.
"But the most effective method to manage worry and any apprehension and worry is to stay ready."
Inhabitants are being advised to secure their homes with sandbags and wooden boards, and to stock up on necessary supplies.
Advisories are also in effect for regions of Haiti encompassing the primary urban center, the Dominican Republic and eastern Cuba, where this storm is anticipated to bring similar effects by the midweek period.
Mudslides already being caused by the hurricane have caused two deaths in Haiti, according to local authorities.
The hurricane is projected to pass over the island nation by the middle of the week before moving through the Caribbean archipelago and out into the Atlantic.
By the moment it reaches the Caribbean nation, it is predicted to have weakened to a third-level cyclone.
Although it is hard to connect particular meteorological occurrences to global warming, experts say it is causing weather phenomena more common and more extreme.
Warmer oceans generate additional humidity in the environment, contributing to the creation of storms.
Ahead of the beginning of the current Atlantic storm period, meteorological authorities predicted increased storm frequency, mentioning elevated ocean temperatures and possible stronger monsoon activity around African coastal regions - where hurricanes often form.
