(CNN) October 3, 2016 - A ferocious hurricane packing 130-mph winds is threatening to wreak havoc on Haiti and Jamaica as it trudges through the Caribbean Sea.
Hurricane Matthew, a slow-moving storm now within roughly 300 miles of Jamaica and Haiti, is expected to dump dozens of inches of torrential rainfall on both islands starting Monday. After that, Matthew is expected to plod north toward Cuba, where it's expected to make landfall near Guantanamo Bay Tuesday night.
"This rainfall will produce life-threatening flash floods and mudslides," the National Weather Service said late Sunday night. "Preparations to protect life and property should be rushed to completion."
Epic rainfall, brutal strength in Haiti
The National Weather Service reported Monday Matthew could dump up to 25 inches of rain on southern Haiti -- including 40 inches in isolated areas.
Matthew will likely make landfall sometime after Monday night just off the western tip of the Tiburon Peninsula, the National Weather Service said. The storm surge is expected to reach 10 feet along the coastline. Rainfall of up to nearly two feet could lead to major flooding and trigger perilous landslides.
In addition, a direct hit on Haiti could also be disastrous as much of the country's infrastructure remains weak after the 2010 earthquake that killed more than 200,000 people. Haiti continues to recover from a cholera outbreak after the quake that killed another 10,000.
