Hurricane Dorian is forecast to strengthen and become a highly dangerous Category 4 hurricane on Sunday, threatening the Atlantic coast of central and south Florida.

Dorian is likely to make landfall on Florida’s eastern coast on Monday, before lingering over central Florida on Tuesday.

In Miami, the Coast Guard has ordered terminals to implement storm stacking plans for containers, to no more than two high for containers containing hazardous materials, and no more than four high for all other containers.

All vessel movements in the region are expected to come to a halt as Dorian bears down on the southeastern US; current forecasts have the storm making landfall along the east coast of Florida Monday morning, potentially as a category 4 hurricane.
