North East Iceland (around Akureyri, Húsavík, Mývatn, Dettifoss, etc): Extreme thawing and risk of floods due to snow melting rapidly (temperature +10/15°C). If roads/streets get flooded, slow down.
Very strong and hazardous waves are expected at Reynisfjara beach today and the next few days. Use extra caution, stay WELL back from the water, and do not leave children unattended! Do not enter the cave!
Considerable avalanche danger (level 3 out of 5) in mountain areas in the Westfjords, Eastfjords and around Tröllaskagi peninsula .
The ice on Lake Mývatn is very thin and the danger of falling through. Do not walk on it!
