School is out and all non-essential work places ordered closed until Thursday after the island’s power grid collapsed.

By Monday afternoon, around 89 percent of customers in the capital had power again, however many residents outside Havana remained without electricity, according to the authorities.

Many Cubans waited in anguish Sunday as electricity on much of the island had yet to be restored days after an island-wide blackout. Their concerns were also raised as Hurricane Oscar made landfall in the southeastern Bahamas and was heading toward their country.
