Tropical Storm Melissa has formed in the warm waters of the Caribbean, about 300 miles south of Port-au-Prince, Haiti, becoming the 13th named storm of the 2025 Atlantic hurricane season. The system, first identified on October 21, reached sustained winds of 45 mph as it moved west-northwest across waters several degrees warmer than usual.
Early forecasts from the National Hurricane Center (NHC) show southern Haiti, Jamaica, and the Dominican Republic directly in the storm’s path—home to about 2.5 million people in low-lying or flood-prone areas. Officials warn the storm’s slow and unpredictable trajectory could make it one of the most dangerous weather events of the season.
A Slow-Moving, High-Impact System
Meteorologists say what makes Melissa so concerning is not just its strength, but its sluggish pace. The storm is expected to stall near Haiti or Jamaica through the weekend, allowing prolonged rainfall and flooding reminiscent of Hurricanes Harvey and Dorian.
“This kind of system lingers long enough to wring out every drop of moisture,” said Dr. Michael Brennan, director of the NHC. Forecast models suggest Melissa could reach hurricane strength by Saturday, with maximum sustained winds near 100 mph and rainfall totals surpassing a foot in some regions.
Heavy rain began to fall Thursday night across Haiti’s southern peninsula, and Jamaica issued tropical storm watches for several coastal parishes. Emergency response leaders warn that mudslides and flash floods could threaten both rural farmland and urban neighborhoods over the coming days.
Evacuations, Disruptions, and Early Impacts
Tens of thousands across the Caribbean are weighing difficult evacuation decisions. Haiti’s interim leadership has issued storm warnings from the Dominican border to Port-au-Prince, though poor roads and limited fuel supplies complicate escape efforts. In Jamaica and the Dominican Republic, shelters have opened in flood-prone areas, stocked with food and medical supplies.
For many Haitians, the decision to leave is fraught. “People here have lived through too many storms to panic, but not enough help to feel safe,” said Marie Délorge, a humanitarian worker stationed near Jacmel. Local radio networks have become lifelines for storm updates in areas where power outages are expected.
The travel sector is already feeling the storm’s reach. Airlines have canceled dozens of flights to Kingston, Port-au-Prince, and Santo Domingo, and major cruise lines have diverted ships to eastern Caribbean ports. Tourism operators, only recently recovering from COVID-era downturns, now brace for major revenue hits. “Every canceled flight and missed cruise stop ripples through the economy,” said travel analyst Paul Kerr in Bridgetown.
Farms and Markets Brace for Impact
Agricultural regions across Haiti, Jamaica, and the Dominican Republic could face heavy losses. Haiti’s southern highlands—rich with coffee, mango, and cacao—are particularly vulnerable to landslides, while Jamaica’s Blue Mountain growers are rushing to protect coffee and banana crops.
Economists warn that damages could total tens of millions of dollars, threatening exports that sustain rural livelihoods. “A single storm can erase an entire season’s progress,” said Dominican agricultural analyst Carlos Ariza.
Global commodity traders are already on alert. Futures for coffee and cocoa saw sharp fluctuations this week amid fears of production delays. “Even a two-week disruption can shift pricing,” noted commodities researcher Emma Troy, citing similar market reactions during Caribbean storms in previous seasons.
Systems Under Strain
Across the three island nations, health workers and government agencies are scrambling to prepare. Hospitals in Jamaica and the Dominican Republic have reinforced emergency wards and stocked antibiotics and water purification tablets. In Haiti, medical responders fear a resurgence of cholera, a persistent danger following major floods.
Economists warn that the storm could also drive up food and transport costs in a region already battling inflation. Haiti’s informal markets and Jamaica’s heavy reliance on imports make both economies highly sensitive to trade disruptions. “Even temporary breaks in supply can ripple fast in small island economies,” said Caribbean Development Bank advisor Livia Clarke.
Meanwhile, construction firms and aid agencies are positioning resources for rapid recovery. The United Nations, Red Cross, and Caribbean Disaster Emergency Management Agency (CDEMA) are pre-positioning materials such as tarps, fuel, and satellite communications kits. “Early mobilization is critical—once roads and ports close, response time doubles,” a CDEMA spokesperson said from Barbados.
A Warming Ocean, a Rising Risk
Melissa’s formation is part of a growing pattern scientists link to warming sea temperatures. “The warmer the water, the more energy a storm can draw,” explained climate researcher Dr. Isaac Horan at the University of Miami. The Caribbean has seen record-high ocean surface temperatures this fall, feeding storms that are slower, wetter, and more destructive.
Experts note that Caribbean nations, though contributing little to global greenhouse emissions, suffer disproportionately from their effects. A 2024 Global Climate Risk Index report ranked Haiti and the Dominican Republic among the world’s ten most climate-vulnerable countries. The pattern echoes global data showing more frequent tropical systems stalling over coastal areas and dumping extreme rainfall.
For residents across the Caribbean, Tropical Storm Melissa represents both an immediate danger and a long-term warning. As rain clouds gather and winds strengthen, families are preparing for another weekend of uncertainty in a region that has weathered too many storms with too few resources.
“The question isn’t just how strong Melissa gets,” said Dr. Brennan, “but how long she stays.”
