Evacuation areas Avalanche weather and wind directions
for snowdrift accumulation
Avalanche paths and notification
Snowdrift accumulation in winds from NW-NE, SW and SSE
Kubbi Snow accumulation from the mountain top
in winds from SW. Known avalanches in
SSE-storm with intense snowfall (unusual
weather).
Flat or concave mountainside without defined avalanche
paths. Evacuation level 2.
Seljalandshlíð,
Seljalandshverfi
Snow accumulation from the mountain top
of Eyrarfjall in winds from NW to NE (a
relatively large fetch). During winds from
N-NE snowdrift from the top of Eyrarfjall
and Gleiðarhjalli into Seljalandshlíð, snow
accumulates from the sides to the gullies.
In the eastern part of the area the avalanche paths are in gul-
lies with flat gravelfans downhill. In the western side above
Seljalandshverfi the paths are on an open mountainside, where
Seljalandsmúli affects the run-out of the avalanches. Dam
completed 2004. Evacuation in 1997, levels 1-3. At present
level 3.
Neðan Gleiðarhjalla
(Eyrarhlíð-Eyrarfjall) (be-
low Gleiðarhjalli)
Generally little snow accumulation. Pos-
sibly snow accumulation in strong winds
from NW-N.
Shallow gullies in cliffs at the mountainside with gravel be-
low. A ca. 400 m wide shelf above cliffs on the mountain.
Evacuation of homes only during exceptional circumstances.
Evacuation level 3.
