Tropical Storm Melissa is forecast to become a infrequent Category 5 hurricane as it shifts towards the Caribbean island, causing dangerous rapid inundation and mudslides.

This weather system, which recorded wind speeds of up to 195 km/h as of 6:00 AM GMT, is presently veering north-west in the Caribbean region and is anticipated to hit the coast by midweek, as reported by weather experts.

Advisories of power cuts and structural damage have been announced as Melissa produces up to 76cm of rain and storm surges as high as thirteen feet above ground. "Find safe refuge immediately," residents have been told.

This hurricane is the 13th named hurricane in the ongoing Atlantic hurricane season, which typically ends in November.

Highest-Level Hurricane Danger

A highest-level cyclone is the strongest type, with sustained winds of at least 157mph.

Although Melissa is set to diminish in strength to a Category 4 storm before arriving at Jamaica, authorities said there was "minimal real distinction in the total effects" upon reaching the coast, and that the cyclone will be "equally strong" when it strikes the nation.

Critical Preparations

With tropical storm-level wind and rainfall already expected well before it passes over central Jamaica - perhaps encompassing the city of Kingston - advisories indicate that "readiness efforts must be accelerated".

"A multi-day period of harmful winds and intense precipitation have begun and will cause severe and deadly flash flooding and numerous mudslides," urged climate experts.

The nation's leader the official commented: "I understand that there are numerous residents who are anxious, who are very concerned, and with good reason: you should be concerned.

"However the most effective method to handle nervousness and any nervousness and worry is to be prepared."

Inhabitants are being advised to secure their homes with sand barriers and wooden boards, and to stock up on necessary supplies.

Broader Impact

Alerts are also ongoing for regions of Haiti such as the main city, Port au Prince, the Dominican Republic and the eastern part of Cuba, where Melissa is anticipated to bring analogous consequences by the middle portion of the coming week.

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

Expected Course

Melissa is forecast to pass over Cuba by midweek before passing across the Caribbean archipelago and entering the open ocean.

By the moment it reaches Cuba, it is forecast to have reduced to a third-level storm.

Environmental Context

Although it is hard to associate individual weather events to climate change, experts say it is resulting in climate patterns increasingly frequent and more intense.

Warmer oceans generate greater water vapor in the environment, helping fuel the creation of storms.

Prior to the beginning of this season's Atlantic storm period, meteorological authorities forecast higher-than-average occurrence, mentioning warmer seas and potential enhanced seasonal rains around West Africa - where hurricanes typically originate.
