Warning due to heavy rainfall and increased river levels
This event is highly unusual and the conditions are extremely hazardous
Tonight, tomorrow and Thursday heavy rainfall, exceeding 100 mm/24 hrs, is forecast in the south- and western parts of Iceland, from Vatnajökull to Ísafjarðardjúp.
Along with the precipitation, extreme runoff from glaciers is expected. Increased water levels in rivers and streams is expected, and due to previous rainfall, the ground is already saturated and river levels high. Risk of flooding is therefore high, especially to the south and west of Langjökull glacier.
Travelers are advised against attempting to cross non-bridged rivers and streams in these hazardous conditions. There is also an elevated risk of landslides in the affected regions.
In urban areas, surface runoff could be a problem. Therefore it is advised, that drains and grids be cleared to handle the rainfall.
Heavy precipitation events for longer periods such as this are highly unusual, and these conditions are extremely hazardous.
