More than 100mm accumulated rain in parts of SW Norway – October 22, 2013

Complex topography of southwestern Norway is often receiving high rainfall amounts given its position relative to storm systems that travel across western Europe towards Scandinavia. As such, strong SW-erlies are usually present ahead of such system, creating favourable environment for excessive non-convective or even convective rainfall towards the SW Norway.

Yesterday, October 23rd, such a system was travelling across the UK and resulted in continuous mostly orographic rainfall from North Sea onshore to SW Norway. A SLGT risk of DAY 1 Outlook for 22/10/2013 has been assigned as high rainfall amounts have been expected. Some weather stations reported more than 100mm of accumulated rain during the last 24 hours (between 22/10/2013 06 UTC and 23/10/2013 06 UTC).
