Hurricane Arthur was upgraded from a tropical storm at 5AM EDT on Thursday. Hurricane warnings are up for the entire North Carolina coastline north to the Virginia border. Max winds are 90 mph; should reach Category 2 intensity early 4th of July morning with winds of 105 mph. Arthur is still 200 mph SW of Cape Hatteras moving NNE at 10-15 mph.
Its interesting to see how Arthur evolved from a disturbance over South Carolina, sliding southeast over the ocean then doubling back north off the coast of Florida over the last 5 days.
has an excellent discussion on the hurricane with wind and wave forecasts. Winds will increase rapidly Thursday evening with max gusts approaching 100 in local areas along the Outer Banks. The window for 80-100 mph will be around 12 hours.
Total rainfall could exceed 7 inches in many areas.
