The low-pressure system will form over Jamaica today and possibly move with heavy rainfall to Florida over the course of the week.

The tropics are showing no signs of cooling down after the National Hurricane Center (NHC) designated an area of disturbed weather in the Caribbean Sea as Potential Tropical Cyclone Eighteen.

"The system is forecast to become a hurricane by Tuesday night and there is a risk of dangerous impacts from hurricane-force winds," the NHC said.

This week Tropical Storm or Hurricane Rafael is likely to form, meaning more rain and storm activity across much of Florida.
