cape hatteras in february what gear should I bring?
Just so you don''t think Jeff is pulling your leg, here''s one of a couple of warnings I found in USA today about severe weather in that area in winter time. Keep in mind that strong temperature gradients across short distances are a recipe for violent weather:

Storms tend to form near Cape Hatteras
By Chad Palmer, USATODAY.com
If you follow East Coast weather you''ll notice that many of the storms that affect the middle Atlantic states and the Northeast form or strengthen off Cape Hatteras, N.C.
Extratropical storms - storms that form and grow away from the tropics - draw their energy from contrasts in air temperatures, and the Atlantic Ocean off the North Carolina Coast is one of those places where the ocean and atmosphere can work together to create strong temperature differences across relatively short distances.
Here, the cold Labrador ocean current from the north Atlantic meets the warm Gulf Stream current from the tropics. The ocean cools air over cold water and heats air over warm water. Thus, big differences in ocean water temperatures help create big air temperature differences.
During winter, the Labrador ocean current creates an especially strong temperature contrast near Cape Hatteras as it meets the Gulf Stream ocean current, which is cooled hardly at all.
When other conditions come together in the right way, the Atlantic off Cape Hatteras breeds ferocious East Coast blizzards. The stormy seas off North Carolina''s Outer Banks - where Cape Hatteras is located - gave that part of the coast the name "Graveyard of the Atlantic." (Related graphic: East Coast storms)
Some times, storms that form here are so fierce that they are called "bombs."

And before you reassure yourself that you''ll be alright if you closely monitor the weather forecast:

Coastal storms confound forecasters
Intense areas of low pressure, develop off the East Coast during late fall, winter and early spring. They usually make life hard for forecasters.
