Cyclone Melissa is forecast to escalate to a infrequent highest-level cyclone as it turns towards Jamaica, delivering life-threatening sudden floods and landslides.

This weather system, which had winds of up to 120 miles per hour as of 0600 Greenwich Mean Time, is presently veering toward the northwest in the Caribbean Sea and is projected to hit the coast by midweek, based on data from hurricane specialists.

Warnings of electricity outages and disruption to utilities have been announced as Melissa brings up to thirty inches of rain and storm surges as high as 13ft above normal levels. "Find safe refuge immediately," inhabitants have been advised.

Melissa is the 13th storm in this year's Atlantic season, which usually concludes in the eleventh month.

Category Five Cyclone Threat

A category five storm is the most intense classification, with wind speeds of at least 157mph.

While this storm is set to weaken to a category four hurricane before reaching Jamaica, authorities 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 nation.

Critical Preparations

With tropical storm-level winds and rain anticipated well in advance long before it crosses Jamaica's central region - possibly even the capital, Kingston - advisories indicate that "preparations should be rushed to completion".

"A multi-day period of destructive gusts and intense precipitation are underway and will cause catastrophic and life-threatening rapid water accumulation and numerous mudslides," advised climate experts.

The country's head of government the statesman said: "I know that there are numerous residents who are anxious, who are extremely apprehensive, and rightfully so: worry is natural.

"However the most effective method to address worry and any nervousness and anxiety is to stay ready."

Locals are being advised to fortify their houses with sand barriers and plywood sheets, and to accumulate essentials.

Broader Consequences

Advisories are also active for areas in Haiti such as the capital, Port au Prince, the Dominican Republic and the eastern part of Cuba, where this storm is projected to bring analogous consequences by the midweek period.

Landslides already being caused by the hurricane have resulted in two fatalities in the country, according to emergency services.

Projected Course

The hurricane is forecast to pass over the island nation by Wednesday before moving through the Caribbean archipelago and out into the open ocean.

By the time it makes contact with the Caribbean nation, it is forecast to have diminished to a category three storm.

Weather Context

While it is difficult to link individual weather events to environmental shifts, experts say it is making meteorological events increasingly frequent and more severe.

Higher ocean heat produce additional humidity in the air, contributing to the formation of hurricanes.

Prior to the start of this season's Atlantic hurricane season, climate agencies projected increased storm frequency, referencing warmer seas and potential enhanced seasonal rains around West Africa - where hurricanes frequently develop.
