Category 5 Melissa to bring catastrophic impacts to the western Caribbean: Haiti, Jamaica and Cuba at risk
Melissa has already turned deadly across Haiti and the Dominican Republic, but AccuWeather meteorologists warn that the worst may be yet to come with the storm on track to intensify.
Warm water in the Caribbean has formed a storm that will bring heavy downpours and flood threats for Jamaica and surrounding areas.
As Hurricane Melissa slowly churns across the warm waters of the western Atlantic over the upcoming days, AccuWeather hurricane experts continue to sound the alarm bells that a very dangerous and deadly situation is unfolding across the Caribbean.
Melissa turns deadly in Haiti, Dominican Republic
As of Saturday afternoon, at least four fatalities have already been attributed to Melissa across Haiti and the Dominican Republic. With additional rain, wind and storm surge expected to be unleashed across the Caribbean as the storm gains strength, conditions are likely to deteriorate rapidly in the coming days.
Into early this week, this storm is forecast to gradually track in a general northwest fashion across a portion of the Western Caribbean. By late Monday, Melissa's track will be influenced by the larger-scale pattern of the jet stream, allowing it to curve northward and shoot northeastward as the week goes on, making multiple landfalls as it travels across the northern Caribbean.
Melissa strengthened to a Category 5 hurricane (maximum sustained winds of 157 mph or greater) early Monday morning prior to its approach along the southern coastline of Jamaica.
What rapid intensification will mean for Jamaica
As Melissa gradually tracked northward toward Jamaica, it crossed over some of the warmest waters in all of the Western Atlantic, which helped to fuel further intensification of the storm. Melissa rapidly intensified from a tropical storm to a major hurricane in about 9 hours on Saturday.

Melissa is expected to make landfall as a powerful Category 5 hurricane at about 7 a.m. Tuesday, Oct. 28, EDT, along the southern shore of Jamaica, about 60 miles west of Kingston.
“Much of Kingston’s critical infrastructure is located in low-lying areas that are vulnerable to storm surge. A key power plant, airport, shipping port, fuel terminal and water treatment plant all sit near the southern coast. A storm surge of 6-10 feet could seriously damage or destroy this infrastructure, worsening immediate impacts and complicating recovery efforts," stated AccuWeather Chief Meteorologist Jon Porter. Near where the storm makes landfall in Jamaica, a storm surge of 10-15 feet can occur.
Porter added that, "Airports will play a key role in disaster relief operations, given the international response that will likely be needed to deliver emergency supplies and assistance.”
Norman Manley International Airport, located in Kingston Harbor on the southeastern coast of Jamaica, is connected to the island by a narrow stretch of highway. This roadway is facing a rather high risk for damage given the current landfall location and projected intensification of the storm in the coming days.
Melissa to carve a path through the northern Caribbean
Across the western Caribbean, the AccuWeather RealImpact™ Scale for Hurricanes is 5, the maximum value possible. This scale, developed by AccuWeather experts, takes into account the risk to lives, property and economic impacts from the storm, including flooding, rain, storm surge and high winds. The Saffir-Simpson Hurricane Wind Scale only takes into account a storm's maximum winds.
The current track of Melissa will also mean a second landfall in eastern Cuba, leading up to midweek.
Cities and communities along the southeastern tip of Cuba are urged to complete preparations as soon as possible as Melissa approaches with wind, rain and a dangerous storm surge along the coast. Rainfall totals are projected to range between 12-18 inches across this corridor of Cuba, which can result in devastating damage to infrastructure, road washouts and mudslides across the varied terrain.
The intense and widespread rainfall will continue across the region for several days as the storm's position comes to a crawl in the western Caribbean.
Duffus added that the prolonged nature of impacts can result in entire communities being cut off from aid and support for multiple days.
Beyond the Caribbean: Where Melissa will travel
Melissa is expected to remain a powerful hurricane as it tracks through parts of the Bahamas this week. By this point, however, it should pick up some forward speed and be pulled out of the Caribbean and into the open waters of the Atlantic. Although later on down the road, Melissa is expected to come close enough to Bermuda to bring impacts as well.
“The timing and strength of a dip in the jet stream over the eastern United States this week will help determine the path that Melissa takes through the northern Caribbean and into the southwestern Atlantic," DaSilva said. "At this time, the odds of 'direct' rain and wind impacts from Melissa reaching the U.S. East Coast are low." Farther out, there is a moderate risk of Melissa hooking westward toward Atlantic Canada.
Once Melissa exits the Caribbean, the closer it could eventually move toward the East Coast of the U.S. and notable indirect impacts are anticipated with assistance of the jet stream and a non-tropical storm between the last days of October to the first days of November.
