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.

Hurricane Melissa became one of the most powerful hurricanes on record to make landfall in the Atlantic Basin.

Arthur Blank, owner of the Atlanta Falcons, has pledged an initial $1.5 million through his foundation to aid Hurricane Melissa relief efforts across Jamaica and the Caribbean.

The most powerful storm to hit the region since 1988 could inundate some areas of eastern Jamaica with up to 40 inches of rain. The arrival of its core has been delayed by stalling.

Today, Today, several developments occurred. Melissa changed into hurricane, before turning into a Category 5 hurricane. Then, it weakened to a Category 4 hurricane and eventually became a Category 3 hurricane before being downgraded to a Category 3 hurricane with sustained winds of 125 mph.

It also marks the first time in 20 years that three or more Category 5 hurricanes have developed over the Atlantic Basin in one season. The last time was in 2005, when Hurricanes Emily, Katrina, Rita, and Wilma all reached Category 5—breaking a record.

Matthew Cappucci, a senior meteorologist at MyRadar and storm chaser, spoke with NBC News’ Kate Snow about his experience flying into the eye of Hurricane Melissa aboard a NOAA aircraft and the concerns over the Category 5 storm making landfall.

Jamaica is bracing for potentially its strongest storm to ever impact the island, as the slow-moving, major Category 5 hurricane closes in. AccuWeather's Leslie Hudson reports from Lake County, FL, where 16 inches of rain in 6 hours triggered a rare flash flood emergency, washing out roads and flooding homes.
