Hurricane Melissa’s duration in Jamaica is ongoing in this moment, but initial assessments indicate the core impact of the storm lasted several hours on land as it moved across the island, with the worst conditions concentrated during landfall and the immediate passage across the southern to central regions. Debris, flooding, and wind-related damage typically persist for hours beyond peak winds, extending into the afternoon as the storm exits and moves back over water. Key points to understand about tropical cyclone duration in Jamaica

• Landfall window: For a major Category 5 landfall, Jamaica experiences the most intense conditions for a few hours around the time the eye crosses the coast. The strongest winds and storm surge are concentrated in this window, after which conditions gradually improve as the core of the storm moves off the island. This suggests a land-time on the order of roughly 4–6 hours for peak impact, though heavy rain and gusts can persist longer in rugged terrain.
• Post-landfall decay: After the core passes, winds typically ease but dangerous residual winds and widespread rainfall can continue for many hours, potentially doubling the on-land exposure time depending on the storm’s speed and structure.
• Rain and flooding: Jamaica’s mountainous terrain enhances rainfall totals and flash flooding/landslide risk that can persist well after the center has moved offshore, often extending into the next day in affected parishes.

What to monitor for ongoing safety

• Local advisories and updates from Jamaica’s Meteorological Service and emergency management officials, which give real-time timing for remaining hazards, including floods and landslides.
• National Hurricane Center advisories for Jamaica-specific impacts and the storm’s progression, including any changes in track, intensity, or timing as Melissa moves across or away from the island.
• Evacuation and shelter instructions for parishes most at risk, particularly coastal low-lying areas and mountainous regions prone to landslides.
