The National Hurricane Centre in the US today said the newest tropical depression is forecast to become a tropical storm as it drifts south-east in the Atlantic.
A tropical storm watch is in effect for Puerto Rico, the US Virgin Islands, the British Virgin Islands and the far eastern portion of the Dominican Republic.
The depression’s maximum sustained winds were nearly 35mph early today. But the hurricane centre expects it to become a tropical storm later in the day.
The tropical depression is centred about 360 miles south-west of San Juan, Puerto Rico.
Further out in the Atlantic, the remnants of what had been Tropical Storm Nana were expected to continue weakening.
