Bahamian Prime Minister Hubert Minnis said on Thursday that the death toll from Hurricane Dorian has risen to 30 in The Bahamas.

Authorities previously reported 20 dead, but have warned that the final figure is sure to be far higher.

Minnis has said that the storm caused “generational devastation.”

The United Nations said 70,000 people in the Bahamas were in “immediate need” of aid.

On Tuesday, Hurricane Dorian moved to the northwest after brutally punishing the northern parts of the Bahamas for more than a day, the Miami-based National Hurricane Center (NHC) said.

The Category 2 storm, with winds of 110 mph, was lashing central Florida’s east coast the National Hurricane Center said.

Life-threatening storm surge and dangerous winds are expected along the state’s coast as well as along the coasts of Georgia, Florida and the Carolinas, regardless of the hurricane’s exact track, the center said.

Houses in some areas of Grand Bahama, where Freeport is located, are covered to the roof by water, while many residents wait to be rescued.

Thousands of houses in the northern Bahamas were flooded by the storm surge from Dorian and streets look like flowing rivers.

In addition, Canadian Prime Minister Justin Trudeau said that he had also spoken with Minnis and announced that he would grant economic aid to the Atlantic archipelago.

Rescue teams are continuing their work in the affected regions.
