Hurricane Maria has been downgraded to a category-four storm, the second highest level.
The hurricane poses a "potentially catastrophic" threat to Caribbean islands which were devastated earlier this month by the powerful Hurricane Irma.
Maria made landfall on the Caribbean island of Dominica as a category-five storm with winds of 260km/h, causing "widespread devastation."
Maria is following the same path as Irma.

The Powerful Category-five Hurricane Irma recently hit Caribbean islands, including Barbuda, Antigua, Puerto Rico, Cuba and the American states of Florida, Georgia and South Carolina.
It left at least 37 people dead and caused billions of dollars worth of damage to property and infrastructure.
The damage in the small Dutch island territory of Sint Maarten alone is estimated to be close to $1.44 billion.
