Cyclone Melissa is forecast to strengthen into a rare highest-level storm as it shifts in the direction of the Caribbean island, delivering life-threatening sudden floods and mudslides.
This weather system, which recorded winds of up to 120 mph as of 0600 Greenwich Mean Time, is currently turning north-west in the Caribbean region and is expected to reach land by Tuesday, as reported by weather experts.
Warnings of blackouts and structural damage have been issued as Melissa brings up to 76cm of rain and sea level surges as high as thirteen feet above ground. "Take cover without delay," locals have been advised.
This hurricane is the 13th storm in the ongoing Atlantic hurricane season, which typically ends in November.
A highest-level cyclone is the most powerful category, with wind speeds of at least 252 km/h.
Even though Melissa is set to weaken to a Category 4 storm before reaching the island, authorities said there was "almost no noticeable change in the overall impacts" upon reaching the coast, and that the cyclone will be "just as powerful" when it impacts the island.
With tropical storm-level gusts and precipitation already expected well before it crosses Jamaica's central region - perhaps encompassing the national capital - alerts indicate that "safety measures need to be finalized quickly".
"A multi-day period of harmful winds and intense precipitation has started and will cause severe and deadly flash flooding and many landslides," counseled climate experts.
The nation's leader Andrew Holness stated: "I know that there are many Jamaicans who are concerned, who are deeply troubled, and with good reason: you should be concerned.
"However the optimal approach to address nervousness and any apprehension and anxiety is to be prepared."
Locals are being told to protect their properties with sandbags and wooden boards, and to gather essentials.
Advisories are also active for areas in the neighboring country such as the capital, Port au Prince, the adjacent nation and Cuba's eastern region, where Melissa is expected to bring similar effects by the middle portion of the coming week.
Rock slides presently generated by the storm have caused two deaths in Haiti, according to emergency services.
The hurricane is forecast to move across Cuba by Wednesday before passing across the Greater Antilles and entering the open ocean.
By the point it arrives at the Caribbean nation, it is anticipated to have reduced to a Category 3 hurricane.
Although it is challenging to link individual weather events to climate change, scientists say it is causing weather phenomena more prevalent and more intense.
Higher ocean heat generate more moisture in the environment, aiding in the creation of tropical cyclones.
Prior to the beginning of this season's Atlantic hurricane season, meteorological authorities forecast increased storm frequency, mentioning warmer seas and likely more intense weather patterns around the western African continent - where hurricanes frequently develop.
