Hurricane Melissa is forecast to strengthen into a infrequent highest-level cyclone as it shifts towards the Caribbean island, bringing deadly rapid inundation and mudslides.
This weather system, which registered winds of up to 120 mph as of 06:00 GMT, is currently turning northwest in the Caribbean region and is expected to make landfall by Tuesday, as reported by meteorological authorities.
Alerts of electricity outages and structural damage have been issued as Melissa brings up to thirty inches of rain and storm surges as high as 13ft above normal levels. "Take cover without delay," locals have been advised.
Melissa is the 13th named hurricane in the ongoing Atlantic storm period, which typically ends in late autumn.
A Category 5 hurricane is the strongest type, with sustained winds of at least 252 km/h.
Even though the hurricane is set to reduce in intensity to a fourth-level hurricane before reaching Jamaica, experts said there was "almost no noticeable change in the general consequences" upon landfall, and that the storm will be "just as powerful" when it impacts the island.
With tropical storm-level winds and rain predicted to begin well before it moves across the island's interior - including potentially the capital, Kingston - advisories state that "readiness efforts must be accelerated".
"An extended timeframe of harmful winds and torrential rain has started and will cause catastrophic and life-threatening flash flooding and multiple mudslides," urged weather authorities.
The nation's leader the official stated: "I understand that there are numerous residents who are concerned, who are extremely apprehensive, and rightfully so: concern is justified.
"But the most effective method to address worry and any unease and worry is to remain prepared."
Inhabitants are being advised to secure their homes with sand barriers and timber panels, and to accumulate necessary supplies.
Advisories are also active for regions of Haiti including the primary urban center, the Dominican Republic and eastern Cuba, where this storm is projected to bring comparable impacts by the middle of next week.
Rock slides already being caused by the hurricane have already killed two in Haiti, according to local authorities.
Melissa is forecast to cross Cuba by midweek before traveling via the Greater Antilles and emerging into the Atlantic.
By the point it makes contact with the Caribbean nation, it is predicted to have diminished to a category three storm.
Even though it is difficult to link specific storms to global warming, researchers say it is causing meteorological events more prevalent and more intense.
Higher ocean heat create greater water vapor in the air, contributing to the formation of storms.
Before the start of this season's Caribbean cyclone season, weather organizations forecast increased storm frequency, mentioning elevated ocean temperatures and likely enhanced seasonal rains around African coastal regions - where tropical systems often form.
