Hurricane Helene strengthens over the eastern Atlantic Ocean: NHC

U.S. Airmen from the South Carolina Air National Guard and 169th Fighter Wing prepare to deploy from Mc Entire Joint National Guard Base to Bluffton South Carolina to support partnered civilian agencies and safeguard the citizens of the state in advance

Hurricane Helene strengthens over the eastern Atlantic Ocean: NHC

Hurricane Florence's offshore winds are causing swells and rip currents up and down the coast. "It's a possibility as we monitor the storm in coordination with the National Hurricane Center".

Forecasters said Florence was expected to become an extremely unsafe major hurricane sometime Monday, and remain that way for days.

"The centre of Hurricane Isaac was located near latitude 14.7 North, longitude 43.9 West. Isaac was moving towards the west near 14 miles per hour". The storm was located roughly 1,170 miles east-southeast of the Cape Fear region, and remained a unsafe Category 4 storm.

In addition, in the Pacific, what's now Hurricane Olivia is forecast to approach Hawaii as a tropical storm on Tuesday.

The largest U.S. Marine Corps base on the East Coast, Camp Lejeune and its extensive beachfront northeast of Wilmington, North Carolina, lie within the NHC's forecast "cone" for possible landfall. The first shows the probability of tropical storm force winds and the second map shows the probability of hurricane force winds. Ilija Cesal told the newspaper he wouldn't worry about buying extra water or other supplies for a few more days.

"Today is the day to get prepared all along the East Coast!" the National Weather Service tweeted on Monday morning. The storm is expected to pass between Bermuda and the Bahamas on Tuesday and Wednesday. The storm could soon be on the brink of a Category 5. The potential for the storm to stall has residents packing sandbags and preparing for the major flooding that could follow. Behind Isaac, Hurricane Helene is gaining strength, with wind speeds of over 105 miles per hour as of Monday afternoon.

Several meteorologists said Florence could do what Hurricane Harvey did past year over Texas, dumping days of rain, although not quite as bad.

There were no backups on USA 278 over the Hilton Head bridges through Bluffton, or on S.C. 170, according to the Beaufort County traffic camera system. Hurricane Isaac, churning in the mid-Atlantic Ocean with wind speeds of around 75 miles per hour, is following closely behind Florence.

"Red, no-swimming flags are flying, and everyone must stay out of the water", Dare County Emergency Management Director Drew Pearson said. "Everyone should start preparing now".

"The bottom line is that there is high confidence that Florence will be a large and extremely unsafe hurricane, regardless of its exact intensity", the hurricane center said.

It said that a hurricane watch means that hurricane conditions are possible within the watch area and Prime Minister Skerrit reminded citizens that Hurricane Maria had increased its intensity "in a matter of hours from a Category 3 to Category 5 storm when it lashed the island on September 18 past year, killing several people and causing hundreds of dollars in losses".

On North Carolina's Ocracoke Island, part of the Outer Banks, Tom Pahl, 66, said he was getting ready to board up his house. Its projected landfall is "still fluctuating depending on which models you look at".

"We're in for a real episode here", McMaster said at a press conference.

"Florence is quickly becoming a powerful hurricane", hurricane specialist Eric Blake wrote. Extremely risky hurricane-force winds could batter it Thursday into Friday.

"There is an increasing risk of life-threatening impacts from Florence: storm surge at the coast, freshwater flooding from a prolonged and exceptionally heavy rainfall inland and damaging hurricane-force winds", a 5 a.m. advisory said.
