SAN JUAN—Many people living near a crumbling dam in storm-battered Puerto Rico have evacuated, Governor Ricardo Rossello said on Monday, as he asked for more government aid to avert a humanitarian crisis after Hurricane Maria.
Much of the Caribbean island, a U.S. territory with a population of 3.4 million, is still without electricity five days after Maria struck with ferocious winds and torrential rains, the most powerful hurricane to hit Puerto Rico in nearly a century.
