A winter weather advisory is in effect until 7am on Saturday for Beaufort, Mainland Hyde, Martin, Outer Banks Dare, Tyrrell, Washington and western Dare County. The threats are black ice and slick roadways.
High-tech buoys will help emergency workers in the Carolina's monitor off-shore wind speeds. That information will then help them determine where the most help is needed even before a hurricane hits.
The Carolina's Coastal Ocean Observing and Prediction system has been in place off the North and South Carolina coasts since 2003, but it hasn't been tested in major hurricane winds.
The buoy system should make it easier to locate possible trouble spots.
