Puerto Rico is bracing for rain, power outages as Tropical Storm Dorian nears the island.
Some 30,000 homes still have blue tarps as roofs and where the 3.2 million inhabitants depend on a shaky power grid that Maria destroyed and remains prone to outages even in the slightest of rain storms.
Dorian was located about 370 miles (595 kilometers) east-southeast of Ponce, Puerto Rico, Tuesday afternoon.
The U.S. National Hurricane Center said it had maximum sustained winds of 50 mph (85 kph) and was forecast to strengthen during the next 48 hours before passing near or south of the U.S. territory on Wednesday as it moves west-northwest at 13 mph (20 kph).
The storm was expected to dump between 3 to 6 inches (8 to 15 centimeters) of rain in the Windward islands, with isolated amounts of 10 inches (25 centimeters).
U.S. Coast Guard personnel could be seen pulling their 45-foot Response Boat--Medium out of the water at Coast Guard Base San Juan.
Crews try to protect their vessels, equipment and infrastructure during a tropical storm or hurricane, so they can be readily available to support Coast Guard missions.
Dorian already caused power outages and downed trees in Barbados and St. Lucia, and a still-uncertain long-term track showed the storm near Florida over the weekend.
The Hurricane Center issued a hurricane watch and a tropical storm warning for Puerto Rico and for the Dominican Republic from Isla Saona to Samaná. Tropical storm watches were in force for Saba, St. Eustatius and parts of the Dominican Republic from Isla Saona to Punta Palenque and from Samaná to Puerto Plata.
