Hurricane Fiona struck Puerto Rico’s south-west coast on Sunday as it unleashed landslides, knocked the power grid out and ripped up asphalt from roads and flung the pieces around.

Forecasters said the storm would cause catastrophic flooding and threatened to dump “historic” levels of rain, with up to 25 inches (64cm) possible in isolated areas.
