Attention
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. However, it is still too early to say whether the event has ended. Travelers are still urged to exercise caution and to leave the area if they notice symptoms that could indicate gas pollution. The Icelandic Meteorological Office will continue to monitor the area closely and provide updates as needed.

The graph shows conductivity measurements in Múlakvísl at Route 1 (Þjóðvegur 1) from 17 August until this morning, 21 August.
The water level in the river did not rise significantly, but the river spread out across its channel, indicating that discharge had increased. The Icelandic Meteorological Office's webcameras near Múlakvísl show this in the following images.
