The USS Nimitz is returning to its home port in Naval Base Kitsap in Washington state after having been deployed to the Middle East for most of the summer as part of the U.S. response to attacks by Yemen’s Houthi rebels on commercial shipping. The carrier is on its final deployment before decommissioning.

Hurricane Melissa strengthened into a Category 5 could and could bring "catastrophic" flash flooding and landslides to Jamaica, Haiti and the Dominican Republic.

Melissa is expected to strengthen from a tropical storm into a major hurricane this weekend, bringing “life-threatening and catastrophic” flash flooding and landslides to the Caribbean.

Tropical Storm Melissa has neared hurricane strength, threatening the northern Caribbean with potentially catastrophic rainfall, flooding and landslides.

"It is more than kind of distressing because you don't know when and you don't know how," said Ewan Simpson, who lives in Jamaica.

Jamaica is expected to be in the storm's eyewall, which refers to the band of dense clouds surrounding the eye of the hurricane. The eyewall generally produces the fiercest winds and heaviest rainfall, according to Deanna Hence, a professor of climate, meteorology and atmospheric sciences at the University of Illinois Urbana-Champaign.
