Hurricane Melissa is predicted to strengthen into a infrequent highest-level hurricane as it shifts toward Jamaica, delivering life-threatening rapid inundation and rock falls.
The hurricane, which recorded winds of up to 195 km/h as of 6:00 AM GMT, is presently veering toward the northwest in the Caribbean Sea and is anticipated to make landfall by early next week, according to weather experts.
Alerts of blackouts and structural damage have been released as Melissa generates up to 30 inches of rain and sea level surges as high as thirteen feet above normal levels. "Seek shelter now," inhabitants have been urged.
Melissa is the 13th named storm in the ongoing Atlantic hurricane season, which typically ends in the eleventh month.
A Category 5 cyclone is the strongest type, with wind speeds of at least 157mph.
Although Melissa is projected to reduce in intensity to a category four cyclone before reaching Jamaica, meteorologists said there was "very little practical difference in the total effects" upon reaching the coast, and that the hurricane will be "equally strong" when it impacts the island.
With storm-force winds and rain already expected long before it crosses central Jamaica - including potentially the capital, Kingston - warnings state that "readiness efforts must be accelerated".
"Several days of damaging winds and intense precipitation have begun and will cause devastating and dangerous rapid water accumulation and numerous landslides," counseled climate experts.
Jamaican Prime Minister the statesman said: "I understand that there are many Jamaicans who are anxious, who are deeply troubled, and appropriately: concern is justified.
"Yet the most effective method to handle nervousness and any unease and anxiety is to be prepared."
Locals are being advised to protect their properties with sand barriers and wooden boards, and to accumulate basic necessities.
Warnings are also in effect for areas in Haiti encompassing the main city, Port au Prince, the Dominican Republic and Cuba's eastern region, where this storm is projected to bring analogous consequences by the middle of next week.
Mudslides currently triggered by the storm have caused two deaths in Haiti, according to the nation's Civil Protection agency.
This weather system is predicted to pass over Cuba by midweek before traveling via the Antillas Mayores and entering the Atlantic Ocean.
By the point it makes contact with the Caribbean nation, it is anticipated to have reduced to a third-level cyclone.
Although it is hard to link individual weather events to environmental shifts, experts say it is resulting in weather phenomena more common and more intense.
Higher ocean heat create additional humidity in the atmosphere, helping fuel the creation of hurricanes.
Ahead of the commencement of the current Atlantic storm period, meteorological authorities forecast higher-than-average occurrence, mentioning heated marine conditions and likely more intense weather patterns around the western African continent - where hurricanes frequently develop.
