Forecaster's remarks

Northeast severe gales in the Westfjords with gusty winds by mountains, mainly in the north. People in this area should secure loose objects outside to prenvent wind damage.

Heavy rain in Southeast-Iceland and the Eastfjords until late evening, but in north parts of the Westfjords and in Strandir-area overnight and tomorrow. Possibility of local flooding, rock- and landslides that could cause damage and cause traffic disruptions.

See weather warnings.

Week overview -

Earthquake activity throughout the country is described in a weekly summary that is written by a Natural Hazard Specialist. The weekly summary is published on the web every Tuesday. It covers the activity of the previous week in all seismic areas and volcanic systems in the country. If earthquake swarms are ongoing or significant events such as larger earthquakes have occurred during the week, they are specifically discussed. More

Remarks of a specialist

Considerable precipitation is expected in South and Southeast Iceland today, rising river levels are likely to accompany this particularly near Vatnajökull and Mýrdalsjökull. Motorists traveling on mountain roads are urged to exercise caution, as fords may see significant water level increases and become impassable.

Localized heavy rain is expected in Strandir and the northern Westfjords today and over the coming days. Water levels in rivers and streams are likely to rise.

Due to malfunction we have turned off the service publishing hydrological data on the map. Instead see the data using our Rauntímavöktunarkerfi.

Situation on the Reykjanes Peninsula - 15.9.2026

Deformation measurements continue to show uplift in the Svartsengi area. Over the past three months, the land has risen by approximately five centimetres. The uplift indicates that pressure continues to build at a depth of several kilometres. As long as uplift continues, the most likely scenario remains that a magma intrusion will propagate from Svartsengi into the Sundhnúkur crater row. Read more

Increased electrical conductivity and gas pollution at Múlakvísl - 1.9.2026

The glacial outburst flood in Múlakvísl, which began on 18 August, now appears to be subsiding. Both conductivity and discharge have decreased since yesterday, and currently there is no gas pollution being detected in the area Read more

Measurements show that uplift at Askja has ceased - 14.8.2026

Measurements by the lake in Askja. Fieldwork in the area was completed this week, and the results indicate that the uplift episode that began in 2021 has ended.

Increased hazard due to changing conditions at the margin of Sólheimajökull glacier - 22.7.2026

Recent changes at the terminus of Sólheimajökull call for increased caution. Unstable glacier ice and rockfall from the surrounding slopes may pose a risk to people visiting the area.

Ground uplift and magma accumulation continue beneath Svartsengi - 9.6.2026

Uplift and magma accumulation continue at Svartsengi, and the trend remains stable. The latest model calculations indicate that around 27.5 million cubic metres of magma have accumulated beneath Svartsengi since around mid-July last year. Read more

The Icelandic Met Office receives international grant to strengthen aviation safety in relation to volcanic hazards - 3.6.2026

In October 2025, the Icelandic Meteorological Office (IMO) received a grant of ISK 147 million from the International Civil Aviation Organization (ICAO) for four new development projects in the fields of volcanic hazards and aviation safety. The projects involve, among other things, the development of new measurement methods, automatic analysis of eruption plumes, coordination of responses among European volcano observatories, and research into the effects of sulphur dioxide (SO₂) on aviation.

Arctic cooperation

The Icelandic Meteorological Office cooperates with many agencies in related fields. With ongoing environmental changes, long term time-series are becoming increasingly important. These include time series of weather-related factors, such as temperature, rainfall, air pressure and solar and cloud cover, time-series on hydrology, glaciology, sea-ice condition, earthquakes, floods, ice and sediment load in rivers. Such data from IMO is important, providing a benchmark for assessing ongoing changes in the Arctic region.
