After mauling Puerto Rico, Hurricane Maria delivered a weaker but still punishing blow Thursday to the Dominican Republic with winds near 115 mph and driving rains as the storm carved an arc of misery through the Caribbean. Maria - now a Category 3 hurricane - was expected to gather some fresh strength over open water before taking aim at the Turks and Caicos Islands, which were battered earlier this month by Hurricane Irma on its deadly path toward Florida.
