Hurricane Melissa, currently a major hurricane at Category 4 strength, is expected to bring life-threatening and catastrophic flash flooding and landslides to Jamaica, southern Hispaniola (Haiti and the Dominican Republic), and the southeastern Bahamas starting today and through the middle of this upcoming week.
For Jamaica, Melissa’s slow movement will bring prolonged impacts that include damaging winds, heavy rainfall, life-threatening flash flooding, numerous landslides, and storm surge. Conditions will begin to deteriorate today, and the strongest winds will arrive Monday night and Tuesday morning.
Extensive infrastructure damage and long-duration power outages are expected to leave some communities isolated for many days.
In Haiti, life-threatening, catastrophic flash flooding and landslides are expected across southwestern Haiti through midweek, likely causing extensive damage and isolation among communities. Strong winds will increase across much of Haiti’s Tiburon Peninsula on Tuesday.
The southern Dominican Republic, Eastern Cuba, Southeastern Bahamas, and the Turks and Caicos will also see significant storm surge, damaging winds, heavy rain, and flooding by Tuesday and Wednesday.

We are closely monitoring AL98, a tropical wave in the eastern Caribbean Sea that has a high (80%) chance of development over the next 7 days and a medium (50%) chance over the next 48 hours.
While the system is still organizing, environmental conditions are expected to become more favorable for tropical cyclone formation as it moves westward into the central Caribbean.
Regardless of development, heavy rain and gusty winds could begin affecting Aruba, Bonaire, and Curaçao over the next couple of days, and a tropical depression or storm could form during that time.

Sending a big Mahalo (thank you) to our partners in Ecuador!
It was great to be back in Ecuador this week as PDC continued work with the Secretaría Nacional de Gestión de Riesgos (SNGR) to advance the National Disaster Preparedness Baseline Assessment (NDPBA). Held in Guayaquil from 13–14 October, this engagement builds on earlier meetings in Guayaquil and Manta.
The NDPBA is designed to promote risk-informed decision-making through evidence-based data and analytics, increase multi-agency coordination, and enhance disaster monitoring and disaster risk reduction initiatives.
During this visit, SNGR leadership and technical staff provided valuable updates and shared critical datasets for the Risk and Vulnerability Analysis and Disaster Management Assessment—including hazard zones, socio-economic indicators, critical infrastructure, and emergency services.
We value the continued collaboration with our Ecuadorian partners and look forward to returning in spring 2026 to share preliminary results ahead of the final event in May.
