Hurricane Watches and Tropical Storm Warnings are in place as Tropical Storm Tammy approaches the northern Leeward Islands just a day after reaching tropical storm strength.

Tammy is expected to strengthen as it move over warm waters, and likely becomes a hurricane by the time it’s near the Leeward Islands. The storm will bring the brunt of impacts to the Lesser Antilles Friday and Saturday.

Tammy will likely become a Category 1 hurricane as it delivers heavy rain and winds to Barbados, Martinique, Guadeloupe and Anguilla.

The northern Windward and Leeward Islands could get up to 6″ of rainfall, with higher amounts up to 10″ possible. The storm will turn north, with impacts not as strong for Puerto Rico and the U.S. Virgin Islands.

The storm is currently 200 miles east of Barbados, slowing moving west before it takes a turn more NW over the weekend.
