Weather Service issues coastal floodThe
National Weather Service in Newport, N.C., has issued a coastal flood
advisory until 6 p.m. today for areas north of Cape Hatteras. In
addition, the high surf advisory issued earlier in the week continues
today, also until 6 p.m.

At the same time, the Weather Service is keeping a wary eye on forecast
models for the weekend, when the gusty, northeast winds -- somewhat
lighter today -- could pick up again, bringing the threat of high seas
and coastal flooding during a full moon.
Forecasters say that a combination of a persistent area of low pressure
several hundred miles offshore to the southeast of the Outer Banks and
a strong high pressure area to the north will keep the winds gusty and
from the northeast for much of the rest of the week.
Breaking waves in the surf zone are forecast for 6 to 9 feet, and the
continued onshore fetch will cause water levels to rise 2 to 3 feet
above normal. Minor ocean overwash is possible on east-facing beaches
on northern Hatteras Island, especially around the time of high tide,
which is at 5 p.m. today.
There has been some ocean overwash already in north Buxton during high tides yesterday afternoon and overnight.
The Weather Service also warns swimmers of strong shorebreak and
a high threat of rip currents, which are most likely several hours
either side of low tide, which occurs late tonight and late morning
Rip currents are powerful, channeled currents of water flowing quickly
away from shore. They typically extend from the shoreline, through the
surf zone, and past the line of breaking waves. Swimmers are advised to
use extreme caution and to never try to swim directly back into shore
against a rip current. Swim parallel to the beach until you are
out of the rip current and then head in.
The northeast wind has backed off some today after gusting well over 30
mph at times on Wednesday. The winds are forecast to continue
somewhat lighter --northeast at about 15 to 20 mph -- into tomorrow.
However, the Weather Service warns that the low pressure now offshore
will continue to move slowly to the west and come ashore south of the
Outer Banks on Friday.
Next, developing low pressure over the southeast coast is expected to
move northeast over the weekend, near the North Carolina Coast.
"There is still considerable uncertainty regarding the eventual track,
and intensity of this system," the Weather Service said in an e-mail
However, if the persistent northeast wind picks up again, coastal
flooding could again be a concern on northern Hatteras. The
flooding threat will be amplified by several days of higher than normal
astronomical tides that will occur around this month's "supermoon" on
Sunday, Sept. 27.
The gray skies and showery weather is also forecast to continue into
the weekend, with the chance of precipitation at 70 percent Friday and
Saturday and 50 percent on Sunday.
The miserable weather should lift out to the northeast late Sunday or
Monday, bringing partly cloudy skies and high temperatures in the upper
70s to around 80 next week.
