The entire island of Puerto Rico was without power on Sunday as Hurricane Fiona made landfall and threatened to cause "catastrophic flooding" and landslides before barreling toward the Dominican Republic, a government agency said.

The hurricane unleashed more rain on Puerto Rico on Monday and National Guard troops rescued hundreds of people who got stranded.

The storm stripped pavement from roads, tore off roofs and sent torrents pouring into homes. It also took out a bridge and flooded two airports. Puerto Rico's ports have been closed and flights out of the main airport cancelled, reports Yahoo!News.

Apple's CEO sent out a Tweet late yesterday promising assistance.

Our hearts are with all the people of Puerto Rico as they come together to rebuild once again. We will donate to assist with immediate relief and ongoing recovery efforts. To everyone still in the path of Hurricane Fiona, please stay safe.
