Cyclone the storm is predicted to escalate to a infrequent category five hurricane as it turns in the direction of the Caribbean island, bringing dangerous sudden floods and mudslides.

This weather system, which had winds of up to 195 km/h as of 06:00 GMT, is currently turning toward the northwest in the Caribbean and is expected to reach land by Tuesday, according to hurricane specialists.

Advisories of blackouts and damage to infrastructure have been issued as this storm produces up to thirty inches of rainfall and coastal flooding as high as thirteen feet above typical tides. "Find safe refuge immediately," inhabitants have been advised.

Melissa is the 13th hurricane in the ongoing Atlantic season, which normally finishes in late autumn.

Category Five Storm Threat

A category five cyclone is the strongest type, with sustained winds of at least 157 miles per hour.

Although this storm is expected to diminish in strength to a category four cyclone before making landfall on Jamaica, authorities said there was "almost no noticeable change in the general consequences" upon landfall, and that the cyclone will be "at least that intensity" when it impacts the country.

Critical Readiness Measures

With tropical storm-strength wind and rainfall predicted to begin long before it passes over central Jamaica - possibly even the national capital - advisories state that "readiness efforts must be accelerated".

"An extended timeframe of harmful winds and heavy rainfall have begun and will cause catastrophic and life-threatening rapid water accumulation and many mudslides," counseled weather authorities.

The nation's leader Andrew Holness said: "I understand that there are numerous residents who are concerned, who are very concerned, and appropriately: worry is natural.

"However the most effective method to manage worry and any nervousness and concern is to remain prepared."

Inhabitants are being instructed to secure their homes with sandbags and wooden boards, and to accumulate essentials.

Broader Consequences

Alerts are also in effect for parts of Haiti encompassing the capital, Port au Prince, the adjacent nation and eastern Cuba, where Melissa is anticipated to bring comparable impacts by the midweek period.

Rock slides currently triggered by the storm have caused two deaths in Haiti, according to emergency services.

Projected Path

This weather system is projected to cross the island nation by the middle of the week before moving through the Greater Antilles and out into the Atlantic Ocean.

By the point it makes contact with the Caribbean nation, it is forecast to have weakened to a third-level cyclone.

Climate Context

Although it is difficult to associate individual weather events to climate change, scientists say it is resulting in meteorological events increasingly frequent and more extreme.

Warmer oceans produce more moisture in the environment, helping fuel the development of hurricanes.

Ahead of the beginning of this year's Caribbean cyclone season, weather organizations projected above-normal activity, referencing warmer seas and potential more intense weather patterns around the western African continent - where tropical systems frequently develop.
