storm systems, whereby in many parts of the island low-level wind speeds in excess of
20 m s 1 in winter are not uncommon. Small-scale convective storm systems are less important
in Iceland than at mid- and low-latitudes. Unlike over mid-latitudes continental regions, thunder-
storms in Iceland are most common during the winter months (Dec – Feb) (Einarsson, 1976). They
typically form when cold air

level, surveys commissioned by the European Com-
munity/the European Union provide an indication of trends in concern about cli-
mate change. Since 1992, such surveys have been undertaken among representative
samples of citizens in its Member States, and specifically on topics related to the
environment (Special Eurobarometers (EB) in 1992, 1995, 2002; and a Flash EB
in 2002). These have included

2007). Highly active volcanic systems as Hekla, Katla, Bárðarbunga and Grímsvötn, have
explosive eruptions rates of 82%, 97%, 90% and 95%, respectively (Gudmundsson & Larsen,
2016; Larsen & Gudmundsson, 2016b, 2016a; Larsen & Thordarson, 2016). Volcanic eruptions
are quite common in Iceland and occur on average every two to five years (Larsen & Eiríksson

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
