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 Caribbean storm — among the most powerful in history, with 185 mph winds — is expected to bring flash-flooding and landslides as it slowly moves across the island and heads north toward Cuba.

Historic, life-threatening flash flooding and landslides are expected in portions of Jamaica, southern Haiti and the Dominican Republic through the weekend, the NHC said. Peak storm surge heights could reach 9 to 13 feet above normal tide levels when the storm makes landfall, accompanied by large and powerfully destructive waves.

CNN’s Erin Burnett speaks to “Capital Weather Gang” Meteorologist Matthew Cappucci about his journey into the eye of Hurricane Melissa, and the danger the storm is expected to bring.

The two categories combined make up about 17 percent of all hurricanes in recorded history. Those reaching Category 5 — like Melissa — historically make up more like 4 percent of hurricanes. And fewer than half of the strongest two categories of hurricanes go on to hit land at such intensity.
