Cyclone Melissa is projected to escalate to a infrequent highest-level storm as it veers toward Jamaica, bringing dangerous rapid inundation and landslides.

The hurricane, which recorded wind speeds of up to 195 km/h as of 0600 Greenwich Mean Time, is currently turning northwest in the Caribbean and is projected to hit the coast by midweek, based on data from hurricane specialists.

Warnings of electricity outages and structural damage have been announced as this storm produces up to thirty inches of rainfall and storm surges as high as 13ft above ground. "Take cover without delay," residents have been told.

The cyclone is the thirteenth storm in the current Atlantic hurricane season, which typically ends in late autumn.

Highest-Level Storm Danger

A highest-level storm is the most powerful category, with winds of at least 157mph.

Even though Melissa is set to weaken to a category four cyclone before reaching Jamaica, meteorologists said there was "almost no noticeable change in the overall impacts" upon landfall, and that the storm will be "at least that intensity" when it impacts the nation.

Urgent Preparations

With tropical storm-strength wind and rainfall anticipated well in advance well before it passes over Jamaica's central region - possibly even the national capital - alerts state that "preparations should be rushed to completion".

"A multi-day period of destructive gusts and intense precipitation have begun and will cause devastating and dangerous sudden floods and many landslides," advised weather authorities.

The nation's leader Andrew Holness commented: "I realize that there are countless citizens who are concerned, who are deeply troubled, and appropriately: worry is natural.

"Yet the most effective method to manage nervousness and any unease and concern is to stay ready."

Locals are being advised to protect their properties with protective bags and timber panels, and to accumulate essentials.

Broader Impact

Alerts are also in effect for areas in the neighboring country such as the main city, Port au Prince, the Dominican Republic and eastern Cuba, where the hurricane is anticipated to bring similar effects by the middle of next week.

Landslides presently generated by the hurricane have resulted in two fatalities in Haiti, according to emergency services.

Expected Path

This weather system is forecast to move across the island nation by the middle of the week before traveling via the Caribbean archipelago and out into the open ocean.

By the moment it arrives at Cuba, it is forecast to have reduced to a Category 3 cyclone.

Environmental Background

Even though it is challenging to connect particular meteorological occurrences to climate change, scientists say it is causing weather phenomena more prevalent and more severe.

Higher ocean heat create more moisture in the environment, contributing to the formation of tropical cyclones.

Prior to the start of this year's Caribbean cyclone season, climate agencies predicted above-normal activity, mentioning warmer seas and possible enhanced seasonal rains around the western African continent - where tropical systems frequently develop.
