Tropical Storm Melissa Forms in the Caribbean, Poses Flood Threat
Tropical Storm Melissa has developed over the Caribbean Sea, bringing heavy rainfall and potential flooding to parts of Haiti and Jamaica. The storm formed on October 21, 2025, and is expected to move westward toward the southwestern portions of Haiti and Jamaica later this week.
Formation and Current Status
As of October 21, 2025, at 15:00 UTC, Tropical Storm Melissa was located approximately 300 miles south of Port-au-Prince, Haiti. The system is moving westward at 14 mph, with maximum sustained winds of 50 mph and an estimated minimum central pressure of 1,003 hPa. Tropical-storm-force winds extend up to 115 miles outward from the center.
Watches and Alerts
A Hurricane Watch has been issued for the southern coast and Tiburon Peninsula of Haiti, while a Tropical Storm Watch has been issued for Jamaica. Both countries are at risk of heavy rainfall, flash floods, and landslides. Residents are advised to complete preparations by Thursday, October 23.
Forecast and Uncertainties
While Melissa is expected to be over the very warm waters of the Caribbean, the forecast track beyond Thursday remains uncertain. The storm's future intensity is also linked to its track, and since that is quite uncertain beyond a couple of days, the strength of the storm is also quite uncertain.
Potential Impacts
Melissa is expected to bring heavy rainfall, with a risk of flash floods and landslides, to parts of Haiti and the Dominican Republic through the weekend. Interests elsewhere in Hispaniola and Cuba should continue to monitor the latest forecasts.
