Follow along here for updates on what could become Hurricane Sara. Forecasters with the National Hurricane Center said Wednesday they are tracking a system in the Caribbean that could strengthen into Hurricane Sara next week.

The NHC said Tuesday it is tracking a tropical wave in the Caribbean Sea that could become a tropical depression by the end of the week.

A storm system, which would earn the name “Sara,” is expected to form soon in the Caribbean, and could affect the United States down the road. It’s too early to know exactly where the storm will go once it forms and what areas will be affected — particularly because the system has no established center of circulation yet.
