A tropical disturbance in the Caribbean Sea is likely to develop into a tropical depression this week and, according to some initial computer models, may become Tropical Storm Sara – the 18th named storm of the 2024 Atlantic hurricane season.

The tropical wave we've been tracking in the Central Caribbean has been tagged Invest 99-L. It will likely be a tropical depression by the end of the week. As the system moves into the western Caribbean Sea, the National Hurricane Center says it's producing disorganized showers and thunderstorms.

There is a strong consensus among the various computer forecast models that the tropical disturbance near Jamaica will organize into a tropical depression before the end of the week and pretty quickly develop into Tropical Storm Sara.
