Winds:

When we give the wind direction during our broadcast we are giving you the direction from which the wind blows. For example, a northeast wind at 10 is a wind blowing from the northeast to the southwest at ten miles per hour. If we stop and think about it that makes perfect sense. A north wind is cold as it brings air down from the north, conversely a south wind is warm as it transports warm air northward from the south.

Greek Derivatives:

Boreas      = North wind

Apeliotos = East wind

Notos       = South wind

Zephyrus   = West wind

You might remember that a zephyr is a refreshing wind. When we speak of 'Nor'easters we are talking about the storms that travel up the coast producing northeast winds. (Areas of low pressure rotate counter clockwise and high pressure systems rotate clockwise.) These northeast winds lock in the cold air and are our big snow makers. In terms of property damage on the shore Nor'easters do far more damage than hurricanes. Nor'easters last longer and are more frequent. When hurricanes travel up the coast the strongest winds reside in the northeast quadrant which remains off shore. The highest wind gust recorded at National is 98 mph on October 15th in 1954 when the remnants of Hurricane Hazel passed between Winchester and Washington.
