Hurricane Melissa is projected to escalate to a infrequent category five cyclone as it veers in the direction of the Caribbean island, causing dangerous flash flooding and rock falls.
This weather system, which recorded wind speeds of up to 195 km/h as of 0600 Greenwich Mean Time, is currently turning northwest in the Caribbean region and is projected to make landfall by early next week, according to weather experts.
Warnings of blackouts and structural damage have been announced as the hurricane generates up to thirty inches of rain and coastal flooding as high as 13ft above normal levels. "Seek shelter now," locals have been told.
This hurricane is the 13th named cyclone in this year's Atlantic hurricane season, which normally finishes in the eleventh month.
A highest-level hurricane is the strongest type, with wind speeds of at least 252 km/h.
Even though Melissa is set to diminish in strength to a Category 4 hurricane before making landfall on the island, authorities said there was "almost no noticeable change in the total effects" upon making contact with land, and that the storm will be "equally strong" when it hits the country.
With tropical storm-level winds and rain anticipated well in advance long before it crosses the island's interior - perhaps encompassing the national capital - warnings emphasize that "readiness efforts must be accelerated".
"An extended timeframe of harmful winds and torrential rain are underway and will cause severe and deadly flash flooding and multiple mudslides," advised weather authorities.
Jamaican Prime Minister Andrew Holness commented: "I realize that there are numerous residents who are worried, who are very concerned, and appropriately: you should be concerned.
"However the most effective method to address worry and any nervousness and anxiety is to remain prepared."
Locals are being told to fortify their houses with protective bags and plywood sheets, and to accumulate necessary supplies.
Warnings are also in effect for parts of the neighboring country such as the capital, Port au Prince, the neighboring country and eastern Cuba, where Melissa is anticipated to bring comparable impacts by the middle of next week.
Rock slides already being caused by the storm have resulted in two fatalities in the country, according to local authorities.
The hurricane is projected to move across Cuba by the middle of the week before passing across the Greater Antilles and entering the Atlantic Ocean.
By the time it reaches the Caribbean nation, it is anticipated to have diminished to a third-level cyclone.
While it is hard to associate particular meteorological occurrences to climate change, scientists say it is causing weather phenomena increasingly frequent and more severe.
Warmer oceans create greater water vapor in the atmosphere, aiding in the formation of storms.
Before the start of the current Atlantic storm period, climate agencies forecast higher-than-average occurrence, referencing heated marine conditions and potential enhanced seasonal rains around West Africa - where tropical systems typically originate.
