Hurricane Melissa has strengthened into a Category 5 storm as it barrels toward the Caribbean, bringing life-threatening winds, heavy rain, and storm surge to several islands in its path.

As of Monday afternoon, Melissa was packing sustained winds near 280 km/h and moving west-northwest toward Jamaica, where it’s expected to make landfall Tuesday morning.

The U.S. National Hurricane Center warns of catastrophic wind damage and rainfall totals that could exceed 300 millimetres in some areas, leading to flash flooding and landslides.

Jamaica’s government has ordered mandatory evacuations in low-lying coastal regions and opened emergency shelters across the island. Forecasters say the storm will then move toward eastern Cuba by late Tuesday and could impact the Bahamas later in the week.

While Hurricane Melissa is not currently projected to reach Atlantic Canada, meteorologists are tracking its potential to curve north later in the week, possibly bringing heavy rain and high surf to parts of Newfoundland or Nova Scotia over the weekend.

Officials across the region are urging people to stay tuned for updates as the storm’s track continues to evolve.
