UPDATE:  Weather Service
upgrades effects of coastal storm

By IRENE NOLAN

The National Weather Service has upgraded the advisories it issued yesterday afternoon for a coastal storm that is winding up this afternoon off the southeast coast of North Carolina.

A strong cold front passed through the Outer Banks early this morning, and a low pressure area formed off the coast along the front.  It is forecast to deepen during the day today.  A strong upper low will cross the area later today.  Winds will increase today as a tight pressure gradient forms between the low offshore and a high building to the north.

The highest winds will be tonight before they start subsiding tomorrow. One Hatteras village resident measured a wind gust of 59 mph shortly after 11 this morning.

Rain began over the area early this morning and is expected to continue through much of the day. Temperatures fell from the low 60s yesterday afternoon into the 40s overnight and will remain there for the rest of the day.

"It will be a cold dreary and blustery day with overcast conditions and light misty rain," the Weather Service said in its forecast discussion.

Here are the current weather warnings and advisories:

  • A high wind warning has replaced the wind advisory.  It is in effect from 2 p.m. Tuesday until 4 a.m. Wednesday.  Winds will pick up through the day, peak tonight, and start subsiding on Wednesday.  Northerly winds of 30 to 40 mph with gusts to 60 mph are forecast.
  • A storm warning has replaced the gale warning for the coastal waters from 3 p.m. Tuesday afternoon until 4 a.m. on Wednesday. A storm warning is issued when winds or wind gusts in the range of 55 to 73 mph are expected. Wind gusts over 60 mph are forecast.  A gale warning remains in effect for the Pamlico Sound.
  • The high surf advisory remains in place from 2 p.m. on Tuesday until 2 p.m. on Wednesday.  The forecast is for breaking waves in the surf zone from 8 to 10 feet and seas over the coastal waters from 15 to 18 feet.
  • A coastal flood warning has replaced the coastal flood advisory and is in effect from 2 p.m. on Tuesday until 4 a.m. on Wednesday. Water level rises of 2 to 4 feet above normal are forecast on the soundside of Hatteras and Ocracoke, and there is a possibility of minor to moderate coastal flooding from Buxton through Ocracoke. Water level rises of 2 feet are expected on the oceanside of the islands with the possibility of ocean overwash from Buxton north along Highway 12, especially at times of high tide.  High tide is about midnight tonight and noon on Wednesday morning.
  • Temperatures will be much cooler.  Highs today are expected to be in the mid-40s, falling to about 40 tonight and rising to the upper 40s to around 50 on Wednesday. Highs could be in the mid-50s to around 60 on Thursday.


After Thursday, the bottom falls out as several bouts of Arctic air invade the region with short spells of warmth in between the cold outbreaks.

A cold front Thursday night is forecast to drop temperatures into the 20s.  The frontal passage will be mostly dry, but there is a possibility of light snow showers or flurries along the coast.

Temperatures Friday will be in the mid- to upper 30s with the low to mid-20s on Friday night.  Slight warmth returns Saturday when temperatures will moderate into the mid- to upper 40s.

Saturday night, a strong Arctic/Siberian front will cross the area, again with a possibility of snow showers.  Temperatures will drop into the upper teens to low 20s across the Outer Banks. 

Sunday will be the coldest day of the outbreak with highs in the mid-20s and lows that night in the mid- to upper teens.Gale force winds are also possible again Saturday night into Sunday.

Temperatures will begin to moderate on Monday when highs will climb back above freezing, perhaps to about 40.
