A tropical storm warning has been issued for Barbados, Dominica, and St. Lucia. A watch was also issued for Puerto Rico and the U.S. Virgin Islands.

Bertha is forecast to approach Barbados on Friday, then pass south of Puerto Rico on Saturday before heading toward the Bahamas.

While forecasts could change, the storm was not expected to become a hurricane.

"The environment surrounding Bertha is not particularly favorable for significant strengthening during the next two days due to modest westerly shear and limited mid-level moisture," the National Hurricane Center said.
