Parts of the northern Caribbean are keeping an eye on Tropical Storm Philippe, which has strengthened slightly.

The National Hurricane Centre says maximum sustained winds have increased to near 85 km/h.

It adds however that little change in strength is forecast the next day or two, with slow weakening forecast this weekend.

There are no watches or warnings in effect at this time, however several are monitoring Philippe, including the northern Leeward Islands, the U.S and British Virgin Islands, and Puerto Rico.

Eyes are also on an active tropical wave in the Central Atlantic.

The NHC says there continue to be signs of organization with a tropical depression or storm expected to form in the next day or so.

The TTMS however says there is no immediate threat to Trinidad and Tobago.
