Hurricane Dorian NOAA 2am update: Water levels RISING along South Carolina coast | World | News

Hurricane Dorian, now a Category 3 hurricane, is the second strongest hurricane on record and the fourth named storm of the 2019 Atlantic hurricane season. Dorian is expected to slam the southeast and mid-Atlantic coasts with damaging winds and life-threatening storm surges over the next few days endangering the lives of US citizens. So what is the latest National Hurricane Center update on Hurricane Dorian?

According to the latest advisory from the NOAA, released at 2am EDT (7am BST), the eye of Hurricane Dorian was located at latitude 31.4 north, longitude 79.6 west, which is around 105 miles south southeast Charleston, South Carolina, and 220 miles south southwest of Wilmington, North Carolina.

The storm was moving towards the north at 7mph, with maximum sustained wind speeds of 115mph.

The advisory reads: “A turn to the north northeast is anticipated today, with a turn toward the northeast tonight.

“A northeastward motion at a faster forward speed is forecast on Friday.

“On the forecast track, the centre of Dorian will continue to approach the coast of South Carolina this morning, move near or over the coast of South Carolina later today, and then move near or over the coast of North Carolina tonight and Friday.”

Hurricane-force winds extend outward up to 60 miles (95km) from the centre, while tropical-storm-force winds extend outward up to 195 miles (315km).

Sustained wind speeds of 49mph were recently recorded at Winyah Bay in South Carolina.

Dorian poses a number of threats to the nearby US coasts, particularly strong force winds, storm surge, heavy rainfall, flash floods, life-threatening surf conditions and tornadoes.

South Carolina Governor Henry McMaster declared a state of emergency for the state, tweeting there was “no more time for hesitation.”

“If you’re in an evacuation zone you need to evacuate now,” he added.

Hurricane Dorian’s storm surge will bring rising water to Charleston – a flat city, just a few feet above sea level and next to the ocean.

Charleston typically floods during rain storms, but this time the storm surge could be higher than 10 feet – just two feet short of a record set 20 years ago by Hurricane Hugo.

Dorian’s proximity to land – and the fact the eye of the storm is 50 miles wide – could mean the vortex’s eye wall may well make landfall, according to CNN meteorologist Chad Myers.

He said: “If this storm is 30 miles offshore, that means the Carolina coast does, in fact, get the eye wall.

“It may not get the centre of the eye, but who cares? The centre of the eye is calm. It is the eye wall that is the most important part.

“And as it turns on up toward the north … even if it’s offshore, the eye wall could be very much onshore.”

Tropical storm conditions are expected along the coast of North Carolina later this morning, with hurricane conditions beginning later today.

The combination of a dangerous storm surge and the tide will cause normally dry areas near the coast to be flooded by rising waters moving inland from the shoreline.

The water could reach the following heights above ground somewhere in the indicated areas if the peak surge occurs at the time of high tide:

  • Isle of Palms to Myrtle Beach SC: five to eight feet
  • Savannah River to Isle of Palms SC: four to seven feet
  • Myrtle Beach SC to Cape Lookout NC: four to seven feet
  • Cape Lookout NC to Duck NC, including Pamlico and Albemarle Sounds and the Neuse and Pamlico Rivers: four to six feet
  • North of Mouth of St. Mary’s River to Savannah River: three to five feet
  • Duck NC to Poquoson VA, including Hampton Roads: two to four feet

Meanwhile, this rise in water levels could result in large and destructive waves, as well as surge-related flooding.

The following rainfall totals are expected to hit the US through Friday:

  • Coastal Carolinas: six to 12 inches, isolated 15 inches.
  • Coastal Georgia: two to four inches, isolated six inches
  • Far southeast Virginia: three to six inches.

Currently the following alerts are in effect:

A Storm Surge Warning is in effect for:

  • Mouth of St. Mary’s River to Poquoson VA
  • Pamlico and Albemarle Sounds
  • Neuse and Pamlico Rivers
  • Hampton Roads

A Hurricane Warning is in effect for:

  • North of Savannah River to the North Carolina/Virginia border
  • Pamlico and Albemarle Sounds

A Hurricane Watch is in effect for:

  • Mouth of St. Mary’s River to Savannah River

A Tropical Storm Warning is in effect for:

  • Mouth of St. Mary’s River to Savannah River
  • North Carolina/Virginia border to Chincoteague VA
  • Chesapeake Bay from Smith Point southward

A Tropical Storm Watch is in effect for:

  • North of Chincoteague VA to Fenwick Island DE
  • Chesapeake Bay from Smith Point to Drum Point
  • Tidal Potomac south of Cobb Island

The next advisory will be issued at 5am EDT (10am).
