Tropical Storm Melissa continues to spin in the Caribbean. At the same time, "life-threatening and catastrophic flash flooding and landslides" are expected over portions of Southern Hispaniola and Jamaica through the weekend, according to the National Hurricane Center (NHC).

The NHC said in an 8 p.m. ET advisory on Friday, Oct. 24, that Melissa was located about 225 miles southwest of Port-Au-Prince and 190 miles southeast of Kingston, Jamaica, with maximum sustained winds of 65 mph with higher gusts.

Melissa is forecasted to become a hurricane by Saturday and a major hurricane by Sunday, Oct. 26.

A hurricane watch is in effect for Jamaica and the southwestern peninsula of Haiti, from the country's shared border with the Dominican Republic to Port-Au-Prince. The peninsula, along with Jamaica, is also under a tropical storm warning.

"Due to Melissa’s slow motion, the risk of a prolonged multi-day period of potentially damaging winds, heavy rainfall resulting in life-threatening flash flooding and numerous landslides, and storm surge continues to increase for Jamaica," NHC forecaster Philippe Papin said.

Heavy rainfall is expected to cause "catastrophic flash flooding and landslides across southwestern Haiti into early next week," according to Papin, who added that "extensive damage to roads and buildings is expected."

Forecasters said Melissa is drifting east-southeast at 2 mph. It is expected to turn to the northeast and north at a "continued slow motion" in the afternoon or night on Friday, Oct. 24. The storm will then drift westward on Saturday, Oct. 25, and continue through Monday, Oct. 27. By early next week, the storm is expected to move near or just south of Jamaica.

Tropical Storm Melissa could become a Category 5 hurricane

The storm could become one of the strongest storms of the season, according to AccuWeather.

"The exceptionally warm waters, reaching hundreds of feet deep, will act like jet fuel — providing extra energy for Melissa," Alex DaSilva, an AccuWeather lead hurricane expert, said. "The warmest water in the Atlantic basin is in the central Caribbean, in the direct path of this storm. Rapid intensification into a Category 5 hurricane is not out of the question this weekend."

The storm could bring powerful winds that could damage buildings, knock over trees, and cause widespread power and communication outages.

'Life-threatening' conditions are expected across the Caribbean

Through Sunday night, Tropical Storm Melissa is expected to bring 8 to 14 inches of rain to the southern Dominican Republic, southern Haiti, and eastern Jamaica. Hurricane conditions will be possible in Haiti on Saturday and in Jamaica on late Saturday or early Sunday.

The northern Dominican Republic, northern Haiti, and western Jamaica are forecast to receive 3 to 5 inches of rain through Sunday night, and flooding impacts could increase across Jamaica in the coming week.

The southern Dominican Republic and eastern Jamaica are expected to face "life-threatening flash flooding and numerous landslides," according to the NHC. In southern Haiti, "catastrophic" flash flooding and landslides are also anticipated.

How do hurricanes form?

Hurricanes are born in the tropics, above warm water. Clusters of thunderstorms can develop over the ocean when water temperatures exceed 80 degrees. If conditions are right, the clusters swirl into a storm known as a tropical wave or tropical depression.

A tropical depression becomes a named tropical storm once its sustained wind speeds reach 39 mph. When its winds reach 74 mph, the storm officially becomes a hurricane.

Prepare now for hurricanes

Delaying potentially lifesaving preparations could mean waiting until it’s too late. "Get your disaster supplies while the shelves are still stocked, and get that insurance checkup early, as flood insurance requires a 30-day waiting period," the National Oceanic and Atmospheric Administration recommends.

  • Develop an evacuation plan. If you are at risk from hurricanes, you need an evacuation plan. Now is the time to begin planning where you would go and how you would get there.
  • Assemble disaster supplies. Whether you’re evacuating or sheltering in place, you’re going to need supplies not just to get through the storm but for a possibly lengthy aftermath, NOAA said.
  • Get an insurance checkup and document your possessions. Contact your insurance company or agent now and make sure you have enough insurance to repair or even replace your home and belongings. Remember, home and renters insurance don’t cover flooding, so you’ll need a separate policy for those. Flood insurance is available through your company, agent, or the National Flood Insurance Program.
  • Create a family communication plan. NOAA says you should take the time now to write down a hurricane plan and share it with your family. Determine family meeting places and make sure to include an out-of-town location in case of evacuation.
  • Strengthen your home. Now is the time to improve your home’s ability to withstand hurricanes. Trim trees and install storm shutters, accordion shutters, and impact glass. Seal outside wall openings.
