the discharge in Skaftá and the
temperature of the flood water close to the glacier margin were measured. The dis-
charge from the subglacial lake during the jökulhlaup was calculated using a hypso-
metric curve for the subglacial lake, estimated from the form of the surface cauldron
after jökulhlaups. The maximum outflow from the lake during the jökulhlaup is esti-
mated as 123 m3 s 1 while

weather forecast:
Two low pressure systems are forecast to reach Iceland during the period from Friday morning until
Saturday evening.
The forecast is for southeast 20-25 m/s, (strong gale to storm) tomorrow, Friday, but south 25-30 m/s
(storm to violent storm) on Saturday. A heavy rainfall warning has also been issued for these lows..
Travel conditions will be poor in the south and west

Saturday afternoon and evening, 21st July, strong southeast- and easterly winds are expected in the southern and western parts of Iceland with heavy rain.
Mean wind speed will be 13 to 20 m/s and occasional

sliding parameters for Hoffellsjökull that resulted in a good
simulation of the observed 20th century evolution of the
glacier geometry. The obtained values for the rate factor
and the sliding parameter are A= 4.6× 10−15 s−1 kPa−3 and
C = 10× 10−15 m a−1 Pa−3, respectively.

Windspeed conversions
The Icelandic Meteorological Office uses the SI (Systeme Internationale d´Unites) unit metres per second (m/s) in windspeed measurements. Here you can convert between different units of windspeed. Type a number into a textbox below and then click outside it. Please note that Beaufort-values are between 0 and 12.
