Warning due to flooding

Rising stream and river levels are expected on the Snæfellsnes peninsula, the Hvítá region (both west and south of Langjökull), around the Eyjafjallajökull and Mýrdalsjökull ice caps, and south of the Vatnajökull ice cap. Travellers are cautioned against fording rivers in these regions. Mudflows (lahars) could occur on the southern slopes of Eyjafjallajökull, for example on the Svaðbælisá river.

Heavy rainfall is forecast for west, south-west, south, and south-east Iceland, beginning late on Monday and lasting throughout Wednesday. In these regions, the heaviest rainfall is expected around mountains and ice caps. Cumulative rainfall amounts could exceed 150 mm over 24 hours and heavy melting of snow and ice is expected (see map).

Cumulative run-off (in millimetres) due to rainfall and meltwater from 07:00 on Monday 30 June to 06:00 on Wednesday 2 July 2014. Note that this forecast only covers 48 hours and rainfall and melting will continue on Wednesday.

According to the latest meteorological forecasts, the approaching low will produce enough rainfall to cause localised flooding. This must be taken into account when making travel plans. Travellers are strongly cautioned against fording rivers in the above mentioned regions.
