MIAMI (AP) -- The National Hurricane Center says a tropical storm is expected to develop later in the day out of a tropical depression that is dumping heavy rain on the Netherlands Antilles islands.
A tropical storm watch is in effect Tuesday for Puerto Rico, the U.S. Virgin Islands, the British Virgin Islands and the far eastern portion of the Dominican Republic.
The depression's maximum sustained winds are near 35 mph. The threshold for a tropical storm is winds near 39 mph.
At 8 a.m. EDT, the depression's center was about 360 miles southwest of San Juan, Puerto Rico, and moving southeast near 3 mph. It is expected to turn gradually to the east and then northeast later Tuesday.
Farther out in the Atlantic, the remnant of Tropical Storm Nana is dissipating.
