Jamaican Prime Minister Andrew Holness on Tuesday said that last week's Hurricane Melissa, the strongest-ever storm to hit its shores, caused damage to homes and key infrastructure roughly equivalent to 28% to 32% of last year's gross domestic product.

Holness told lawmakers the estimate was conservative, based on damages assessed so far, and that short-term economic output could decline by 8% to 13%.

He said costs would push up Jamaica's debt-to-GDP ratio and that his government would activate emergency provisions to temporarily suspend the country's fiscal rules.

Holness, whose government set out credit and insurance provisions for a storm similar to last year's Hurricane Beryl, said he was seeking financial support from regional allies, development agencies and the private sector.

"Experts describe Melissa to be on the very edge of what is physically possible in the Atlantic Ocean, a storm powered by record sea temperatures," he said.

"Its force was so immense that seismographs hundreds of miles away registered its passage," he added.

"Hurricane Melissa wasn't only a tragedy: It was a warning."

Scientists say storms are intensifying faster as a result of greenhouse gas emissions warming ocean surfaces, piling up fuel for seasonal storms. Caribbean leaders have long called for reparations from wealthy heavy-polluting nations in the form of aid or debt relief.

Holness pledged to rebuild infrastructure to withstand the worsening impacts of climate change, including moving parts of the electric grid underground.

"Every repaired bridge, re-roofed home and rebuilt road must be designed for the storms of tomorrow, not the storms of yesterday," he said.
