Hurricane Melissa is projected to escalate to a uncommon highest-level cyclone as it shifts towards the Caribbean island, causing dangerous flash flooding and mudslides.
This weather system, which registered winds of up to 120 mph as of 6:00 AM GMT, is currently turning northwest in the Caribbean region and is projected to make landfall by midweek, based on data from weather experts.
Advisories of electricity outages and disruption to utilities have been announced as the hurricane generates up to 76cm of rain and coastal flooding as high as 4m above normal levels. "Seek shelter now," locals have been told.
The cyclone is the 13th named cyclone in the ongoing Atlantic season, which normally finishes in the eleventh month.
A highest-level hurricane is the most powerful category, with sustained winds of at least 157 miles per hour.
Even though Melissa is projected to diminish in strength to a category four cyclone before arriving at the island, meteorologists said there was "very little practical difference in the total effects" upon reaching the coast, and that the cyclone will be "just as powerful" when it impacts the country.
With tropical storm-level gusts and precipitation already expected ahead of it passes over Jamaica's central region - possibly even the city of Kingston - warnings indicate that "preparations should be rushed to completion".
"An extended timeframe of destructive gusts and torrential rain are underway and will cause severe and deadly rapid water accumulation and multiple mudslides," counseled climate experts.
Jamaican Prime Minister the official stated: "I understand that there are countless citizens who are anxious, who are deeply troubled, and appropriately: you should be concerned.
"But the optimal approach to manage nervousness and any unease and anxiety is to stay ready."
Residents are being advised to secure their homes with sandbags and plywood sheets, and to stock up on essentials.
Warnings are also ongoing for parts of Haiti such as the capital, Port au Prince, the adjacent nation and eastern Cuba, where Melissa is anticipated to bring comparable impacts by the middle portion of the coming week.
Landslides presently generated by the hurricane have already killed two in the country, according to local authorities.
Melissa is forecast to pass over Cuba by the middle of the week before passing across the Greater Antilles and entering the open ocean.
By the time it makes contact with Cuba, it is predicted to have reduced to a third-level storm.
Although it is challenging to link particular meteorological occurrences to environmental shifts, researchers say it is making meteorological events increasingly frequent and more extreme.
Warmer oceans generate greater water vapor in the atmosphere, helping fuel the formation of tropical cyclones.
Before the start of the current Atlantic storm period, climate agencies predicted increased storm frequency, citing warmer seas and likely more intense weather patterns around West Africa - where tropical systems typically originate.
