Disturbance 2. A large non-tropical low pressure system is expected to develop this weekend over the northeastern Caribbean sea and southwestern Atlantic.

The disturbance is expected to merge with a larger system developing to its southwest by the end of the weekend and further development is not anticipated at that time.
