The National Hurricane Center is tracking Invest99L as it moves over the central Caribbean Sea and gives the tropical rainstorm a 90% chance of developing into a tropical depression in the next two days.

A tropical wave producing a cluster of showers and thunderstorms across the Caribbean has an 80% chance of becoming a tropical depression.

The system, whether it develops or not, is expected to dump rain on Jamaica and then turn slowly to the northwest by early next week as it moves into the western Caribbean and approaches Central America. It’s then forecast to move toward Mexico’s Yucatan peninsula approaching the Gulf of Mexico.
