Hurricane Melissa intensified to Category 5 early Monday as it neared Jamaica. It's forecast to dump up to 30 inches of rain on Jamaica there and bring a life-threatening storm surge.

Melissa is forecast to make landfall on the island Monday night and Tuesday and cross southeastern Cuba and the Bahamas through Wednesday.

Melissa was centered about 130 miles south-southwest of Kingston, Jamaica, and about 315 miles south-southwest of Guantánamo, Cuba, the Miami-based U.S. National Hurricane Center said.

The hurricane had maximum sustained winds of 160 mph and was inching west at 3 mph, the center said.

Category 5 is the highest on the Saffir-Simpson scale, meaning it has winds of at least 157 mph. Melissa is the strongest hurricane in recent history to directly hit the small Caribbean nation.

Some local areas of eastern Jamaica could get 40 inches of rain while western Haiti could get 16 inches, according to hurricane center. "Catastrophic flash flooding and numerous landslides are likely," it warned.

"Destructive winds and storm surge and catastrophic flooding will worsen on Jamaica through the day and into tonight," CBS News meteorologist Nikki Nolan stressed.

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

"I want to urge Jamaicans to take this seriously," said Desmond McKenzie, deputy chairman of Jamaica's Disaster Risk Management Council. "Do not gamble with Melissa. It's not a safe bet."

The hurricane was expected to make another landfall later Tuesday in eastern Cuba. A hurricane warning was in effect for Granma, Santiago de Cuba, Guantánamo and Holguin provinces, while a tropical storm warning was in effect for Las Tunas. Up to 20 inches of rain were forecast for parts of Cuba, along with a significant storm surge along the coast.

Melissa could be the strongest hurricane Jamaica has experienced in decades, said Evan Thompson, principal director at Jamaica's meteorological service. He warned that cleanup and damage assessment would be severely delayed because of anticipated landslides, flooding and blocked roads.

In addition to the rainfall, Melissa is likely to cause a life-threatening storm surge on Jamaica's southern coast, peaking as much as 13 feet above ground level, near and to the east of where the center of Melissa makes landfall, the U.S. center said.

"Don't make foolish decisions," warned Daryl Vaz, Jamaica's transport minister. "We are in a very, very serious time over the next few days."

The storm already has dropped heavy rain in the Dominican Republic, where schools and government offices were ordered to remain closed on Monday in four of nine provinces still under red alert. The Dominican Republic shares the island of Hispaniola with Haiti.

Melissa damaged more than 750 homes across The Dominican Republic , displacing more than 3,760 people. Floodwaters also have cut access to at least 48 communities, officials said.

In Haiti, the storm destroyed crops in three regions, including 37 acres of maize at a time when at least 5.7 million people, more than half the country's population, is experiencing crisis levels of hunger, with 1.9 million of those facing emergency levels of hunger.

"Flooding is obstructing access to farmland and markets, jeopardizing harvests and the winter agricultural season," the U.N.'s Food and Agriculture Organization said.

Melissa was expected to keep dumping torrential rain over southern Haiti and the southern Dominican Republic in upcoming days.
