Many roads were blocked and some 80,000 people, or 40 percent of the population, were without power, the overseas territories ministry said in a statement. The country is on high alert for flooding and mudslides. Reports from reconnaissance aircraft indicate that the area of hurricane-force winds has increased in size.

Several of those islands were devastated earlier this month when Irma rampaged through the Caribbean.

Puerto Rico had always been spared from a direct hit by hurricanes that tend to veer north or south of the island.
The footage showed the storm ready to pound an island that was already hit hard by Hurricane Irma only two weeks ago.
Maria is forecast to then continue north, avoiding the Turks and Caicos, the Bahamas and Florida, before ending up out to sea.
Three Category 4 hurricanes have made a USA landfall in a little less than a month, causing billions of dollars in damage and likely leading to the retirement of the names Harvey, Irma and Maria from use in future hurricane seasons.
