Winds and Storms
The prevailing wind direction is easterly. Westerlies are very infrequent. Generally speaking, wind speeds tend to be higher in the highlands, but topographical features can aggravate winds and cause strong gusts in lowland areas. Wind speed frequently reaches 18 m/s (59 ft/s) ; on stormy days it averages 50 m/s (164 ft/s). Heavy dust storms can be generated by strong glacial winds, and can be very strong. Up to 10 t (9.8 long tons; 11.0 short tons) of material can be in motion per transect per hour. These storms are very frequent in the early summer in the arid highland areas north of the Vatnajökull glacier.
Thunderstorms are extremely rare in Iceland, with fewer than five storms per year in the southern part of the island. They are most common in late summertime. They can be caused by warm air masses coming up from the continent, or deep lows from the southwest in wintertime. Lightning can usually be observed in connection with ash plumes erupting from the island’s volcanoes.

Famous quotes containing the words winds and/or storms:
“The cold wet winds ever blowing,
And the shadowy hazel grove
Where mouse-grey waters are flowing,
Threaten the head that I love.”
—William Butler Yeats (1865–1939)
“In the midst of this chopping sea of civilized life, such are the clouds and storms and quicksands and thousand-and-one items to be allowed for, that a man has to live, if he would not founder and go to the bottom and not make his port at all, by dead reckoning, and he must be a great calculator indeed who succeeds.”
—Henry David Thoreau (1817–1862)
