Hurricane the storm is predicted to escalate to a uncommon highest-level cyclone as it shifts in the direction of Jamaica, bringing deadly flash flooding and rock falls.
The cyclone, which had winds of up to 195 km/h as of 6:00 AM GMT, is now shifting toward the northwest in the Caribbean Sea and is expected to reach land by early next week, according to meteorological authorities.
Alerts of blackouts and damage to infrastructure have been issued as this storm generates up to thirty inches of precipitation and sea level surges as high as 4m above normal levels. "Seek shelter now," residents have been urged.
This hurricane is the 13th hurricane in the ongoing Atlantic hurricane season, which usually concludes in the eleventh month.
A category five cyclone is the most intense classification, with wind speeds of at least 157 miles per hour.
While this storm is expected to weaken to a category four hurricane before arriving at Jamaica, meteorologists said there was "almost no noticeable change in the total effects" upon landfall, and that the storm will be "just as powerful" when it impacts the country.
With storm-force wind and rainfall already expected long before it passes over the island's interior - including potentially the national capital - alerts emphasize that "safety measures need to be finalized quickly".
"A multi-day period of harmful winds and heavy rainfall have begun and will cause catastrophic and life-threatening rapid water accumulation and many rock slides," counseled weather authorities.
The country's head of government Andrew Holness said: "I realize that there are countless citizens who are worried, who are deeply troubled, and rightfully so: you should be concerned.
"Yet the best way to address worry and any unease and worry is to remain prepared."
Locals are being advised to protect their properties with protective bags and plywood sheets, and to gather essentials.
Warnings are also active for parts of Haiti such as the capital, Port au Prince, the Dominican Republic and the eastern part of Cuba, where this storm is anticipated to bring comparable impacts by the middle portion of the coming week.
Mudslides currently triggered by the storm have resulted in two fatalities in Haiti, according to local authorities.
The hurricane is forecast to pass over the island nation by the middle of the week before traveling via the Greater Antilles and out into the Atlantic Ocean.
By the point it reaches the Caribbean nation, it is forecast to have diminished to a Category 3 cyclone.
While it is challenging to link particular meteorological occurrences to climate change, researchers say it is making meteorological events more prevalent and more severe.
Higher ocean heat generate greater water vapor in the environment, contributing to the formation of storms.
Prior to the start of this year's Atlantic hurricane season, weather organizations projected increased storm frequency, mentioning elevated ocean temperatures and likely more intense weather patterns around African coastal regions - where Atlantic storms frequently develop.
