Eastern Dare

The NWS Storm Prediction Center has issued a
Tornado Watch for portions of

       eastern North Carolina
       far southeastern Virginia
       coastal waters

Effective this Wednesday morning from 310 am until 800 am EST.

Tornadoes... hail to 1 inch in diameter... thunderstorm wind gusts
to 70 mph... and dangerous lightning are possible in these areas.

The Tornado Watch area is approximately along and 50 statute
miles either side of a line from 45 miles south southwest of
Wilmington North Carolina to 40 miles east northeast of Elizabeth
City North Carolina. For a complete depiction of the watch see
the associated watch outline update (wous64 kwns wou1).

Remember... a Tornado Watch means conditions are favorable for
tornadoes and severe thunderstorms in and close to the watch
area. Persons in these areas should be on the lookout for
threatening weather conditions and listen for later statements
and possible warnings.

Other watch information... continue... ww 800...

Discussion... sly winds at 20-25 kt had advected a moisture boundary
layer... with dewpoints into the mid 60s... across the ern Carolinas
and far sern VA... ahead of a stationary front. A weak upper wave
appears to have aided the development of elevated thunderstorms on
the cold side of the front. As these storms shift ewd... the updrafts
should be able to tap into moist and unstable air mass. With
effective shear at 60 kt and low level srh around 500 m2/s2...
rotating storms are likely with the potential of a tornado or two.

Aviation... tornadoes and a few severe thunderstorms with hail
surface and aloft to 1 inch. Extreme turbulence and surface wind
gusts to 60 knots. A few cumulonimbi with maximum tops to 400.
Mean storm motion vector 23040.

... Coastal Flood Advisory in effect from 9 am this morning to
1 am EST Thursday...
... High surf advisory in effect from 9 am this morning to 7 PM EST
this evening from Cape Hatteras south...

The National Weather Service in Newport/Morehead City has issued
a high surf advisory... which is in effect from 9 am this morning
to 7 PM EST this evening. A coastal Flood Advisory has also been
issued. This coastal Flood Advisory is in effect from 9 am this
morning to 1 am EST Thursday.

Gale force south to southwest winds with gusts up to 45 mph will
develop along the coast today. These winds will increase waters levels
2 to 3 feet above normal on the Soundside of the Outer Banks.
This will result in minor flooding adjacent to the sound from
Rodanthe to Wanchese around the time of high tide. The strong
winds will also generate high surf conditions along south facing
beaches from Cape Hatteras to Emerald Isle with breaking waves
around 7 to 9 feet. High tide will occur around 1 PM this
afternoon. Increasingly rough surf and the degraded dunes from recent
storms will make the coastline more susceptible to additional
beach erosion. The winds and seas will gradually subside late
tonight.

Precautionary/preparedness actions...

A high surf advisory means that high surf will affect beaches in
the advisory area... producing dangerous rip currents and
localized beach erosion.

A coastal Flood Advisory indicates that onshore winds and tides
will combine to generate flooding of low areas along the shore.

... Wind Advisory now in effect until 6 PM EST this evening...

The Wind Advisory is now in effect until 6 PM EST this evening.

Gusty southeast winds early this morning will shift to the
southwest later this morning and afternoon. Sustained winds of 25
to 35 mph are expected... with gusts of 40 to 50 mph possible.

Precautionary/preparedness actions...

A Wind Advisory means that winds of 31 to 39 mph with higher
gusts are expected. Winds this strong can make driving
difficult... especially for high profile vehicles. Use extra
caution.
