Hurricane Melissa is projected to become a uncommon category five cyclone as it shifts toward the Caribbean island, bringing dangerous flash flooding and mudslides.
This weather system, which registered wind speeds of up to 195 km/h as of 0600 Greenwich Mean Time, is presently veering north-west in the Caribbean region and is anticipated to make landfall by midweek, based on data from hurricane specialists.
Alerts of blackouts and structural damage have been announced as the hurricane produces up to 76cm of rainfall and sea level surges as high as 13ft above ground. "Find safe refuge immediately," inhabitants have been urged.
The cyclone is the 13th named hurricane in the current Atlantic season, which typically ends in the eleventh month.
A Category 5 storm is the most intense classification, with winds of at least 157mph.
Although Melissa is expected to weaken to a category four storm before reaching Jamaica, authorities said there was "almost no noticeable change in the general consequences" upon reaching the coast, and that the cyclone will be "at least that intensity" when it impacts the nation.
With tropical storm-level winds and rain anticipated well in advance long before it crosses the island's interior - possibly even the national capital - warnings emphasize that "readiness efforts must be accelerated".
"An extended timeframe of harmful winds and heavy rainfall has started and will cause severe and deadly rapid water accumulation and many landslides," counseled climate experts.
Jamaican Prime Minister the statesman commented: "I understand that there are many Jamaicans who are anxious, who are extremely apprehensive, and with good reason: you should be concerned.
"Yet the most effective method to address nervousness and any unease and worry is to remain prepared."
Residents are being told to protect their properties with sand barriers and wooden boards, and to stock up on necessary supplies.
Warnings are also in effect for parts of Haiti encompassing the main city, Port au Prince, the neighboring country and the eastern part of Cuba, where this storm is expected to bring similar effects by the midweek period.
Rock slides presently generated by the hurricane have resulted in two fatalities in the country, according to the nation's Civil Protection agency.
This weather system is predicted to pass over the island nation by the middle of the week before moving through the Greater Antilles and emerging into the Atlantic Ocean.
By the moment it arrives at Cuba, it is forecast to have weakened to a third-level hurricane.
While it is challenging to connect individual weather events to global warming, researchers say it is making weather phenomena more common and more intense.
Higher ocean heat produce more moisture in the atmosphere, helping fuel the formation of tropical cyclones.
Prior to the start of this season's Atlantic storm period, weather organizations forecast above-normal activity, referencing elevated ocean temperatures and potential more intense weather patterns around African coastal regions - where Atlantic storms frequently develop.
