Cyclone Melissa is forecast to become a infrequent highest-level storm as it veers toward the Caribbean island, bringing dangerous sudden floods and mudslides.

This weather system, which recorded wind speeds of up to 195 km/h as of 6:00 AM GMT, is currently turning north-west in the Caribbean and is anticipated to reach land by midweek, based on data from meteorological authorities.

Alerts of electricity outages and disruption to utilities have been announced as Melissa generates up to 76cm of rainfall and sea level surges as high as 4m above normal levels. "Seek shelter now," residents have been urged.

This hurricane is the 13th hurricane in the ongoing Atlantic season, which typically ends in late autumn.

Highest-Level Hurricane Risk

A Category 5 cyclone is the strongest type, with wind speeds of at least 252 km/h.

Although the hurricane is expected to weaken to a category four storm before making landfall on Jamaica, experts said there was "almost no noticeable change in the general consequences" upon landfall, and that the hurricane will be "at least that intensity" when it hits the nation.

Immediate Preparations

With storm-force gusts and precipitation anticipated well in advance long before it moves across Jamaica's central region - possibly even the city of Kingston - warnings emphasize that "safety measures need to be finalized quickly".

"An extended timeframe of destructive gusts and intense precipitation has started and will cause severe and deadly rapid water accumulation and many landslides," urged weather authorities.

The nation's leader Andrew Holness said: "I realize that there are countless citizens who are concerned, who are very concerned, and with good reason: concern is justified.

"However the best way to manage anxiety and any unease and worry is to be prepared."

Locals are being told to protect their properties with sand barriers and wooden boards, and to accumulate essentials.

Wider Effects

Advisories are also active for parts of Haiti including the primary urban center, the neighboring country and Cuba's eastern region, where this storm is projected to bring comparable impacts by the midweek period.

Landslides already being caused by the hurricane have caused two deaths in Haiti, according to emergency services.

Future Trajectory

Melissa is forecast to move across Cuba by Wednesday before moving through the Caribbean archipelago and emerging into the Atlantic.

By the moment it arrives at the Caribbean nation, it is forecast to have weakened to a category three storm.

Weather Background

Although it is difficult to connect specific storms to environmental shifts, experts say it is making meteorological events more prevalent and more severe.

Higher ocean heat generate greater water vapor in the environment, aiding in the development of hurricanes.

Ahead of the beginning of this season's Atlantic hurricane season, meteorological authorities projected increased storm frequency, mentioning elevated ocean temperatures and possible stronger monsoon activity around the western African continent - where Atlantic storms frequently develop.
