Tropical Storm Melissa is projected to strengthen into a uncommon category five cyclone as it shifts toward Jamaica, bringing life-threatening rapid inundation and rock falls.
This weather system, which registered winds of up to 120 mph as of 0600 Greenwich Mean Time, is now shifting toward the northwest in the Caribbean Sea and is expected to make landfall by midweek, according to weather experts.
Alerts of power cuts and structural damage have been issued as Melissa produces up to thirty inches of precipitation and coastal flooding as high as 13ft above typical tides. "Take cover without delay," locals have been urged.
Melissa is the thirteenth cyclone in the ongoing Atlantic hurricane season, which usually concludes in the eleventh month.
A category five cyclone is the strongest type, with winds of at least 252 km/h.
Even though this storm is expected to reduce in intensity to a fourth-level storm before reaching the island, authorities said there was "minimal real distinction in the total effects" upon making contact with land, and that the cyclone will be "at least that intensity" when it hits the island.
With storm-force wind and rainfall anticipated well in advance long before it moves across Jamaica's central region - possibly even the national capital - alerts state that "safety measures need to be finalized quickly".
"Several days of destructive gusts and heavy rainfall has started and will cause devastating and dangerous flash flooding and many rock slides," advised meteorological officials.
Jamaican Prime Minister the official commented: "I understand that there are countless citizens who are concerned, who are very concerned, and with good reason: worry is natural.
"Yet the most effective method to address worry and any apprehension and anxiety is to be prepared."
Residents are being told to protect their properties with sandbags and wooden boards, and to accumulate essentials.
Advisories are also ongoing for areas in Haiti encompassing the main city, Port au Prince, the adjacent nation and the eastern part of Cuba, where Melissa is anticipated to bring comparable impacts by the middle portion of the coming week.
Mudslides presently generated by the hurricane have already killed two in the country, according to the nation's Civil Protection agency.
This weather system is predicted to cross the island nation by Wednesday before moving through the Antillas Mayores and out into the Atlantic.
By the moment it reaches Cuba, it is predicted to have weakened to a category three storm.
While it is hard to connect individual weather events to global warming, researchers say it is resulting in climate patterns increasingly frequent and more intense.
Increased sea temperatures generate additional humidity in the environment, contributing to the development of tropical cyclones.
Ahead of the beginning of this year's Atlantic storm period, weather organizations predicted higher-than-average occurrence, citing warmer seas and potential stronger monsoon activity around African coastal regions - where hurricanes frequently develop.
