Tropical Storm Melissa is predicted to strengthen into a uncommon highest-level hurricane as it turns towards the Caribbean island, bringing life-threatening sudden floods and mudslides.

The hurricane, which registered wind speeds of up to 195 km/h as of 0600 Greenwich Mean Time, is currently turning northwest in the Caribbean region and is expected to reach land by Tuesday, based on data from meteorological authorities.

Warnings of electricity outages and disruption to utilities have been issued as the hurricane brings up to 76cm of precipitation and sea level surges as high as 4m above typical tides. "Seek shelter now," residents have been advised.

The cyclone is the thirteenth storm in this year's Atlantic storm period, which usually concludes in late autumn.

Most Intense Hurricane Danger

A category five cyclone is the most intense classification, with wind speeds of at least 252 km/h.

Although the hurricane is expected to weaken to a category four storm before arriving at Jamaica, meteorologists said there was "almost no noticeable change in the overall impacts" upon landfall, and that the storm will be "just as powerful" when it strikes the country.

Urgent Safety Steps

With tropical storm-level winds and rain predicted to begin ahead of it crosses Jamaica's central region - including potentially the city of Kingston - warnings emphasize that "preparations should be rushed to completion".

"Several days of destructive gusts and heavy rainfall are underway and will cause severe and deadly sudden floods and many mudslides," urged weather authorities.

The country's head of government Andrew Holness commented: "I realize that there are numerous residents who are anxious, who are extremely apprehensive, and rightfully so: worry is natural.

"Yet the most effective method to manage nervousness and any unease and worry is to be prepared."

Inhabitants are being advised to fortify their houses with sand barriers and plywood sheets, and to stock up on necessary supplies.

Broader Impact

Advisories are also active for regions of the neighboring country encompassing the capital, Port au Prince, the adjacent nation and eastern Cuba, where Melissa is expected to bring analogous consequences by the middle of next week.

Mudslides currently triggered by the hurricane have resulted in two fatalities in Haiti, according to local authorities.

Future Course

The hurricane is forecast to cross Cuba by Wednesday before passing across the Caribbean archipelago and entering the Atlantic.

By the time it makes contact with Cuba, it is anticipated to have diminished to a Category 3 hurricane.

Climate Connection

Although it is challenging to connect individual weather events to climate change, scientists say it is causing climate patterns increasingly frequent and more extreme.

Higher ocean heat produce additional humidity in the environment, contributing to the creation of tropical cyclones.

Before the start of this year's Caribbean cyclone season, meteorological authorities projected increased storm frequency, referencing elevated ocean temperatures and possible enhanced seasonal rains around West Africa - where tropical systems typically originate.
