coast, wind forcing is the primary
driver of sea level extremes but less so for the Kattegat/Skagerak region than for the Baltic (M.
Hieronymus, J. Hieronymus, and Arneborg, 2017). Like in Norway, atmospheric pressure is the
most influential contributor to mean sea level changes on timescales up to a few years in the UK
but steric changes dominate on decadal timescales (Dangendorf, Calafat, et al

the maximum discharge of jökulhlaup water at the glacier
terminus is estimated as 97 m3 s 1. This jökulhlaup was a fast-rising jökulhlaup as
other jökulhlaups in Skaftá and cannot be described by the traditional Nye-theory of
jökulhlaups. The total volume of flood water was estimated as 53 Gl. The average
propagation speed of the subglacial jökulhlaup flood front was found to be in the range

cold bias, compared with station measurements. To test, whether this is due to the HARMONIE
model core or the external surface scheme, biases of 2-m temperature from SURFEX are com-
pared with biases of temperature projected from the lowest two model levels to 2 mAGL. It is
found that the negative temperature biases are due to shallow inversion layers near the ground,
which are introduced

Warning due to gale winds and heavy precipitation
20.7.2012
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

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
