Winds
Wind Vector — The wind vector indicates the direction of the surface wind to the nearest 30˚ increment
(e.g. 30˚, 60˚, 90˚, 120˚, etc).
Wind Speed — In general, the sum of the wind barbs is the sustained surface wind speed.

Wind is gusting 5 — 10 kts more than
sustained speed.
Wind is gusting 11 kts or more above its
sustained speed.

The symbol above indicates the surface wind at KFRM is
coming from a direction of 300° at a speed of 25 knots,
gusting to 36 knots or greater.
To interpret wind speed, add the values of each of the
wind speed barbs. In this example, there are two long
barbs (10 knots each) and one short barb (5 knots each).
Thus, the total wind speed is 25 knots. Adding the gust
offset to this figure gives winds gusting to 36 knots.
