Tropical Storm the storm is forecast to become a rare category five storm as it turns towards the Caribbean island, delivering dangerous rapid inundation and mudslides.
This weather system, which recorded wind speeds of up to 120 mph as of 6:00 AM GMT, is currently turning toward the northwest in the Caribbean region and is projected to make landfall by early next week, based on data from hurricane specialists.
Alerts of electricity outages and structural damage have been issued as Melissa generates up to 76cm of precipitation and storm surges as high as 13ft above normal levels. "Take cover without delay," locals have been urged.
The cyclone is the 13th named cyclone in the ongoing Atlantic storm period, which usually concludes in the eleventh month.
A category five cyclone is the strongest type, with wind speeds of at least 157mph.
Although Melissa is set to reduce in intensity to a Category 4 hurricane before reaching the island, meteorologists said there was "minimal real distinction in the general consequences" upon landfall, and that the storm will be "just as powerful" when it strikes the island.
With tropical storm-strength winds and rain anticipated well in advance ahead of it crosses central Jamaica - possibly even the city of Kingston - alerts state that "safety measures need to be finalized quickly".
"A multi-day period of harmful winds and intense precipitation are underway and will cause devastating and dangerous sudden floods and multiple mudslides," advised meteorological officials.
The nation's leader the statesman stated: "I know that there are many Jamaicans who are anxious, who are extremely apprehensive, and appropriately: worry is natural.
"Yet the optimal approach to handle anxiety and any unease and anxiety is to stay ready."
Inhabitants are being told to fortify their houses with sandbags and plywood sheets, and to stock up on necessary supplies.
Warnings are also ongoing for areas in Haiti including the primary urban center, the adjacent nation and the eastern part of Cuba, where the hurricane is projected to bring similar effects by the middle portion of the coming week.
Mudslides currently triggered by the hurricane have already killed two in the country, according to emergency services.
This weather system is projected to pass over Cuba by the middle of the week before passing across the Antillas Mayores and out into the Atlantic Ocean.
By the time it reaches the Caribbean nation, it is forecast to have weakened to a category three cyclone.
Although it is difficult to associate particular meteorological occurrences to global warming, scientists say it is making weather phenomena increasingly frequent and more intense.
Increased sea temperatures generate greater water vapor in the environment, aiding in the development of hurricanes.
Ahead of the start of this year's Atlantic hurricane season, meteorological authorities projected higher-than-average occurrence, referencing heated marine conditions and potential more intense weather patterns around African coastal regions - where hurricanes typically originate.
