Hurricane forecasters will be keeping a close eye on the Caribbean this weekend.

A tropical disturbance is expected to form there in the next few days, and it could become a tropical depression by early next week, according to the National Hurricane Center.

Forecasters at the hurricane center on Thursday were also watching a second area in the southwestern Atlantic that could develop into a subtropical depression soon. It is forecast to meander near Bermuda for the next several days before moving into a more hostile environment.

The soon-to-be Caribbean system could bear more watching. However, it’s too soon to know if it could eventually affect the United States.

The hurricane center said an area of low pressure is expected to form in the eastern Caribbean this weekend.

It will be in a good environment for development, and forecasters said a tropical depression could form early next week as the disturbance tracks to the west or west-northwest and into the central Caribbean.

The hurricane center put the probability of a depression forming at 50 percent.

A system has to have a defined center of circulation and winds of at least 39 mph to become a tropical storm and get a name. The last name on the list is Lisa.

The tropical Atlantic hasn’t had a named storm since Tropical Storm Karl dissipated early on Oct. 15 in the southern Gulf of Mexico before sloshing onshore in Mexico.

The Atlantic hurricane season has just about a month left to go. The last day will be Nov. 30.
