It is the strongest storm to hit the island country in at least 150 years and the most powerful recorded anywhere in 2025. It has caused severe flooding and mass evacuations across Jamaica and along the storm’s projected path, which includes Cuba and the Bahamas.

��Ǿ�Ʒ�� meteorology professor John Gyakum, along with the revered late Massachusetts Institute of Technology meteorologist Fred Sanders, first coined the term in a paper they published in 1980. They used the phrase to describe powerful cyclones that get their energy from rapid drops in pressure caused by hot and cold temperatures colliding.

"If the term itself — ‘bomb’ — helps to spur more constructive research, then I’m happy."―John Gyakum
