Cyclone the storm is projected to escalate to a infrequent Category 5 cyclone as it veers towards Jamaica, delivering life-threatening flash flooding and rock falls.

The cyclone, which registered winds of up to 195 km/h as of 06:00 GMT, is now shifting toward the northwest in the Caribbean and is anticipated to hit the coast by midweek, as reported by weather experts.

Advisories of power cuts and disruption to utilities have been issued as Melissa produces up to 30 inches of rainfall and storm surges as high as 13ft above typical tides. "Take cover without delay," residents have been told.

The cyclone is the 13th cyclone in the ongoing Atlantic storm period, which normally finishes in late autumn.

Category Five Cyclone Risk

A highest-level cyclone is the most powerful category, with sustained winds of at least 252 km/h.

Even though Melissa is projected to reduce in intensity to a fourth-level cyclone before arriving at Jamaica, experts said there was "minimal real distinction in the overall impacts" upon landfall, and that the cyclone will be "equally strong" when it strikes the island.

Urgent Readiness Measures

With storm-force winds and rain anticipated well in advance ahead of it passes over central Jamaica - possibly even the national capital - advisories state that "preparations should be rushed to completion".

"An extended timeframe of damaging winds and heavy rainfall are underway and will cause severe and deadly sudden floods and many rock slides," advised climate experts.

Jamaican Prime Minister the official stated: "I know that there are numerous residents who are concerned, who are deeply troubled, and with good reason: concern is justified.

"But the optimal approach to handle nervousness and any unease and anxiety is to be prepared."

Locals are being told to fortify their houses with sand barriers and wooden boards, and to stock up on basic necessities.

Regional Consequences

Warnings are also active for parts of Haiti including the main city, Port au Prince, the adjacent nation and eastern Cuba, where Melissa is projected to bring analogous consequences by the midweek period.

Mudslides currently triggered by the storm have already killed two in Haiti, according to local authorities.

Future Course

This weather system is forecast to move across the island nation by Wednesday before passing across the Greater Antilles and out into the open ocean.

By the moment it makes contact with Cuba, it is forecast to have weakened to a third-level storm.

Environmental Context

Although it is hard to connect particular meteorological occurrences to global warming, scientists say it is causing meteorological events increasingly frequent and more severe.

Warmer oceans produce additional humidity in the environment, aiding in the development of hurricanes.

Before the start of this year's Atlantic hurricane season, meteorological authorities forecast above-normal activity, citing warmer seas and likely more intense weather patterns around African coastal regions - where hurricanes typically originate.
