Hurricane Maria made landfall as a category five storm ‑ the highest level ‑ with winds of 260km/h.
It was briefly downgraded to a category four, but is back to a five as it moves towards Puerto Rico and the Virgin Islands.
It made landfall in Dominica, whose Prime Minister said his house had been devastated.
Forecasters say it poses a "potentially catastrophic" threat to Caribbean islands in its path.
Many islands in the path of Maria are still recovering from the devastation of Hurricane Irma earlier this month.
