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.

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.
