A tropical depression is likely to form as a tropical wave moves westward into the western Caribbean Sea later this week, the National Hurricane Center said.

Conditions look favorable for a broad area of low pressure in the central Caribbean Sea to become a tropical depression in the next day or two. Specifically, its development probability is at a 90% within the next 48 hours.

A broad area of low pressure is expected to form in the western Caribbean Sea over the next several days. Disorganized storms could become better organized in a tropical environment that is likely to support gradual development. A tropical depression may form by this weekend while moving slowly westward.

It looks like another tropical depression could form in the western Caribbean Sea in a few days. The National Hurricane Center has raised the chances to high — 80 percent — that a tropical depression will form by the end of the 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 disturbance swirling over the central Caribbean Sea now has a high chance of developing into a tropical depression by the end of the week, and some computer forecast models show it continuing to strengthen.
