FOX Weather Hurricane Specialist Bryan Norcross discusses Tropical Storm Melissa as it strengthens in the Caribbean. The intensifying storm set to slam Jamaica and Haiti, bringing heavy rain, high winds and rapid storm surge posing a potentially deadly scenario in the Caribbean.

Invest 98L in the eastern Caribbean is expected to strengthen into a tropical depression or tropical storm over the next few days.

The National Hurricane Center said there’s a medium chance (60 percent) that a tropical depression will form in the Caribbean Sea later this week. Whenever a system forms in the Caribbean hurricane-watchers in the U.S. take notice, because there’s a chance the system could end up affecting the Gulf or U.S. East Coast.

Tropical Storm Melissa could become a dangerous hurricane in the Caribbean over the coming days. Meanwhile, a long-duration lake-effect rain event is unfolding across the Great Lakes.
