Cyclone Melissa is predicted to escalate to a infrequent category five storm as it veers towards the Caribbean island, causing deadly sudden floods and rock falls.

This weather system, which registered wind speeds of up to 120 mph as of 0600 Greenwich Mean Time, is presently veering toward the northwest in the Caribbean and is anticipated to make landfall by midweek, based on data from weather experts.

Warnings of blackouts and damage to infrastructure have been issued as this storm brings up to 76cm of precipitation and storm surges as high as 4m above normal levels. "Seek shelter now," inhabitants have been urged.

The cyclone is the 13th hurricane in the current Atlantic season, which usually concludes in the eleventh month.

Category Five Hurricane Risk

A Category 5 cyclone is the most powerful category, with wind speeds of at least 157mph.

Although this storm is projected to reduce in intensity to a Category 4 storm before reaching the island, authorities said there was "almost no noticeable change in the total effects" upon landfall, and that the storm will be "at least that intensity" when it impacts the island.

Critical Preparations

With storm-force gusts and precipitation predicted to begin ahead of it passes over the island's interior - including potentially the national capital - warnings indicate that "readiness efforts must be accelerated".

"Several days of harmful winds and torrential rain has started and will cause devastating and dangerous sudden floods and multiple landslides," urged weather authorities.

Jamaican Prime Minister Andrew Holness said: "I realize that there are numerous residents who are anxious, who are very concerned, and appropriately: worry is natural.

"However the optimal approach to address nervousness and any apprehension and concern is to stay ready."

Inhabitants are being instructed to fortify their houses with protective bags and plywood sheets, and to stock up on basic necessities.

Wider Impact

Alerts are also in effect for regions of the neighboring country including the main city, Port au Prince, the neighboring country and the eastern part of Cuba, where this storm is anticipated to bring analogous consequences by the middle of next week.

Rock slides already being caused by the hurricane have caused two deaths in Haiti, according to the nation's Civil Protection agency.

Expected Trajectory

This weather system is predicted to pass over Cuba by the middle of the week before moving through the Antillas Mayores and entering the Atlantic Ocean.

By the moment it makes contact with Cuba, it is predicted to have reduced to a category three storm.

Climate Context

Even though it is difficult to connect particular meteorological occurrences to climate change, scientists say it is making climate patterns more common and more extreme.

Increased sea temperatures generate greater water vapor in the environment, helping fuel the formation of storms.

Ahead of the commencement of this year's Atlantic hurricane season, meteorological authorities forecast increased storm frequency, referencing elevated ocean temperatures and possible stronger monsoon activity around West Africa - where Atlantic storms typically originate.
