Lightning flashes in the eyewall of Category 5 Melissa are a marker of how strong the storm is. It reached a central pressure of 892 millibars, among the lowest ever recorded in the Atlantic Ocean. It is tied as the third-most intense Atlantic storm with the devastating 1935 Labor Day hurricane.

The U.S. Air Force Reserve's 53rd Weather Reconnaissance Squadron, known as the "Hurricane Hunters," were forced to turn back at one point due to heavy turbulence after flying into the eye of Hurricane Melissa on Monday.

Jamaica is expected to be in the storm's eyewall, which refers to the band of dense clouds surrounding the eye of the hurricane. The eyewall generally produces the fiercest winds and heaviest rainfall, according to Deanna Hence, a professor of climate, meteorology and atmospheric sciences at the University of Illinois Urbana-Champaign.

The erratic and slow-moving storm has killed at least three people in Haiti and a fourth person in the Dominican Republic, where another person remains missing.

Melissa is the fifth hurricane of the 2025 Atlantic hurricane season, joining Erin, Gabrielle, Humberto and Imelda.
