Wind Barbs
determining wind direction

Wind barbs point in the direction "from" which the wind is blowing. In the case of the diagram below, the orientation of the wind barb indicates winds from the Northeast.

The term easterly means that the winds are from the east. In the example above, the winds are out of the northeast, or northeasterly. On the otherhand, the term "eastward" means that the winds are blowing towards the east.
