The storm passed through the southeast islands including Mayagua, Inagua, Crooked Island Acklins, Long Cay and Ragged Islands, on Thursday and Friday.
Ahead of the Hurricane UNDP deployed crisis response experts to several Caribbean countries, including Jamaica and Haiti, where nine UNDP staff members are supporting crisis coordination in impacted communities in the north. UNDP is also working closely with national authorities in Turks and Caicos, St. Martin and Bahamas to provide support and immediate and long-term recovery measures.
It's set to smash into Florida state later today.
As of Friday night, the storm was honing in on Hurricane Irma as a Category Four storm, packing extremely unsafe winds of 150 miles (240 kilometers) per hour.
Angela Fritz, an atmospheric scientist and the Washington Post's deputy weather editor, explained what happened. Footage of a dry Bahamas shoreline hit the internet shortly after Irma swept through the Caribbean Islands.
"Basically, Hurricane Irma is so strong and its pressure is so low, it's sucking water from its surroundings into the core of the storm", she writes.
Irma is sucking water from shorelines and pulling it into the eye of the storm as it charts a path to the Florida coast.
Hurricane Irma is strong enough to completely change the shape of an ocean.
Meteorologists caution people not to walk on the dry seabed as it will not be safe to be in the area when the water returns.
"The ocean may be experiencing the effects of what I call the hurricane 'bulge, '" she writes.
He said: "Care must be taken in this case because the water often returns with even greater fury".
The hurricane is expected to skirt around Miami, but the city is being lashed by heavy rain.
