"Today I am announcing more than $60 million in funding to help coastal areas in Puerto Rico become better prepared for a storm," Biden said during his visit to Puerto Rico.
These funds will be used for creating a flood warning system and flood walls, he added.
Biden recalled that since last November, Puerto Rico has received more than $700 million in infrastructure investments.
Hurricane Fiona made landfall in Puerto Rico on September 18, causing a power outage across the island. The hurricane was accompanied by record rainfall in some regions. Biden has promised a major boost of federal aid to the Caribbean island.
