Hurricanes Isaac and Florence continue to pose problems for Caribbean countries

The order which helps mobilize resources to prepare for the storm directs state agencies to work closely with localities to identify any needs in advance of its possible arrival

An increase in forward speed is expected during the next couple of days.

Hurricane Helene is moving west-northwest over the eastern Atlantic and is strengthening quickly over the tropical Atlantic.

Since early last week, Florence went from a tropical storm to a Cat 4 hurricane, weakened down to a tropical storm over the weekend, then reintensified into Cat 4 hurricane early this week.

The National Hurricane Center (NHC) says Hurricane Helene is now located about 375 miles west of the southernmost Cabo Verde Islands.

Hurricane Florence is now a category 4 hurricane.

As three powerful storms march one by one across the Atlantic Ocean toward the U.S. East Coast and the Caribbean, a fourth is getting ready to roll over the Hawaiian Islands.

Residents of North Carolina's low-lying barrier islands say they have already felt the impacts of Hurricane Florence.

In addition, the National Hurricane Center said that it will likely issue watches for "life-threatening storm surge" across three states.

The storm is still days away from landfall, and the forecast track will probably change at least a little.

The storm's center will move northwest between Bermuda and the Bahamas on Tuesday and Wednesday. "It's going to destroy homes", said Jeff Byard, an official at the Federal Emergency Management Agency.

Motorists streamed inland on highways converted to one-way routes Tuesday as more than 1 million people in three states were ordered to get out of the way of Hurricane Florence, a hair-raising storm taking dead aim at the Carolinas with 130 miles per hour winds and potentially ruinous rains. Typically, local governments in North Carolina make the call on evacuations.

Forecasters say the hurricane's strength is expected to fluctuate but it still will be a unsafe storm by the time it reaches the coast of SC or North Carolina on Thursday.

The storm's potential path also includes half a dozen nuclear power plants, pits holding coal-ash and other industrial waste, and numerous eastern hog farms that store animal waste in massive open-air lagoons.

Oliva said various models have the storm's eye making landfall anywhere between Myrtle Beach, South Carolina, and Cape Hatteras in the Outer Banks. Tropical storm force winds extend outward up to 115 miles from the storm's center.

Maximum sustained winds remain near 70 miles per hour (110 km/h) with higher gusts.

The hurricane's impacts could range from a strong storm surge to flooding from torrential rainfall and hurricane-force winds.

The Atlantic hurricane season that usually starts in June, has now peaks on September 10.

Should Hurricane Isaac begin to grow, islands beyond the Lesser Antilles such as Puerto Rico, Haiti and the Dominican Republic will brace themselves for the possibility of weathering another storm.
