Officials have warned that Tropical Storm Melissa, which has already killed four people, could spark a "humanitarian disaster" as it's forecast to rapidly intensify into a major hurricane. Melissa remained nearly stationary in the central Caribbean on Friday,

Best-case scenario: “The best-case scenario for Florida would be if Melissa moves over eastern Cuba or Hispaniola and then gets pulled out to sea. That would spare Florida from impacts, though it would likely bring life-threatening and possibly catastrophic flooding to parts of Hispaniola, eastern Cuba, and the Dominican Republic."

Melissa is forecast to rapidly intensify into a major hurricane and bring life-threatening rainfall, landslides and storm surge to Jamaica, Haiti and elsewhere.

Cool front forecasts can be unreliable seven days in advance but AccuWeather is keen on low temps in the 60s for Nov. 1.

Tropical Storm Melissa was nearly stationary in the central Caribbean on Friday, with forecasters warning that it could strengthen and swipe Jamaica as a powerful hurricane and dump a staggering amount of rain -- up to 35 inches -- on southwest Haiti,
