Hurricane the storm is forecast to escalate to a infrequent Category 5 cyclone as it veers in the direction of the Caribbean island, causing deadly flash flooding and mudslides.
The cyclone, which had wind speeds of up to 195 km/h as of 06:00 GMT, is now shifting toward the northwest in the Caribbean Sea and is anticipated to make landfall by midweek, based on data from weather experts.
Warnings of blackouts and disruption to utilities have been released as the hurricane generates up to 30 inches of rainfall and sea level surges as high as 13ft above typical tides. "Take cover without delay," inhabitants have been urged.
The cyclone is the 13th cyclone in this year's Atlantic season, which normally finishes in late autumn.
A highest-level hurricane is the strongest type, with wind speeds of at least 157 miles per hour.
Even though the hurricane is set to reduce in intensity to a Category 4 hurricane before reaching the island, experts said there was "minimal real distinction in the total effects" upon making contact with land, and that the storm will be "just as powerful" when it hits the island.
With storm-force winds and rain anticipated well in advance long before it moves across central Jamaica - perhaps encompassing the capital, Kingston - warnings indicate that "safety measures need to be finalized quickly".
"An extended timeframe of destructive gusts and torrential rain have begun and will cause catastrophic and life-threatening flash flooding and numerous rock slides," urged meteorological officials.
Jamaican Prime Minister Andrew Holness commented: "I know that there are many Jamaicans who are concerned, who are extremely apprehensive, and rightfully so: you should be concerned.
"Yet the most effective method to address anxiety and any nervousness and anxiety is to be prepared."
Residents are being told to protect their properties with protective bags and timber panels, and to stock up on basic necessities.
Advisories are also active for areas in the neighboring country such as the main city, Port au Prince, the neighboring country and eastern Cuba, where Melissa is expected to bring comparable impacts by the middle of next week.
Mudslides currently triggered by the cyclone have already killed two in the country, according to local authorities.
Melissa is projected to pass over the island nation by Wednesday before moving through the Antillas Mayores and emerging into the Atlantic.
By the point it reaches the Caribbean nation, it is predicted to have reduced to a third-level hurricane.
Although it is challenging to connect individual weather events to climate change, researchers say it is resulting in climate patterns more prevalent and more intense.
Higher ocean heat generate greater water vapor in the atmosphere, aiding in the creation of hurricanes.
Ahead of the beginning of the current Caribbean cyclone season, meteorological authorities predicted increased storm frequency, citing warmer seas and possible stronger monsoon activity around the western African continent - where Atlantic storms typically originate.
