Snow cover (in Norwegian)

Torsdag morgon snøar det lett i indre delar av regionen. Nysnø frå dei siste dagane har lagt seg over eit laust lag av rim, kantkorn og delvis omdanna snø. Torsdag morgon ligg det mykje laussnø i overflata som kan flyttast når vinden aukar.

Det nedsnødde lause laget av kantkorn og rim vart danna i overflata under kuldeperioden i slutten av november og har stor utbreiing.

Nokre stader under tynt snødekke har det danna seg begerkrystallar ved bakken.

Tysdag vart det observert fleire små laussnø og flakskred i Jostedal. Det vart også observert skytande sprekkar i snødekket der vinden har danna flak i Sogndalsdalen.

Observasjonar torsdag viser at det er aktive vedvarande svake lag i snødekket som gjev skytande sprekkar.
