Live map: Track Hurricane Maria's path
This map displays live data generated by the National Hurricane Center, which is currently tracking the path of Hurricane Maria.
By Thursday, the hurricane had ripped through Puerto Rico, leaving a trail of destroyed homes and knocking out power in the entire U.S. territory, which will take months to repair, officials said. Gov. Ricardo Rossello told CNN that one casualty was reported, but because of a lack of communication in some areas, the total death toll isn't known.
Hurricane Maria killed at least seven people on the island of Dominica and two people in the French territory of Guadeloupe, according to news reports.
President Donald Trump approved disaster declarations for Puerto Rico and the U.S. Virgin Islands this week to speed federal financial support.
The Category 3 storm was moving northwest toward the Dominican Republic and the Turks and Caicos islands on Thursday.
