A global severe weather update tracking thunderstorms in the US with damaging winds and hail, heavy rainfall and landslide risks in Norway's Vestlandet, and flooding in Tunisia that has suspended classes.
Norway's Vestlandet region faces an orange-level landslide and flood warning this weekend due to a low-pressure system bringing 60-80 mm of rain (up to 100 mm locally), strong winds, and possible thunderstorms, prompting road closures, cleanup of drainage systems, and expectations of multiple landslides with major consequences; yellow warnings apply to parts of Møre og Romsdal and for flooding. [3] [4] Meteorologist Halldis Berge stated it will be a wet weekend as NVE issued an orange danger warning for landslides from Saturday to Sunday morning for Vestland and parts of Rogaland, with yellow level in parts of Møre og Romsdal. [3] The warning forecasts up to 60–80 millimeters of rain over large parts of Vestlandet, with some places possibly receiving up to 100 millimeters of local precipitation, most rain expected in the middle areas. [3] [4]
An orange danger warning for landslides means NVE expects several landslide events, some with major consequences, and exposed buildings may be affected while roads and railways may be impacted. [4] People are advised to check and clear drains, culverts, manholes and other waterways as wind may cause leaves to fall and prevent water from draining, with risk of local flooding and aquaplaning. [4] Motorists should drive according to conditions and follow advice from local authorities. [4] On the Vestlandet, southwesterly wind is first expected, later westerly and northwesterly up to stiff and periodically strong gale, followed by showers and risk of thunder after the first precipitation front.
