Do nedele m\u00e1 postupne klesa\u0165 teplota, sobot\u0148aj\u0161ie sne\u017eenie bude trochu silnej\u0161ie ako to nede\u013en\u00e9. Noc zo soboty na nede\u013eu prinesie siln\u00fd severn\u00fd n\u00e1razov\u00fd vietor. Moment\u00e1lne m\u00e1me vo v\u0161etk\u00fdch pohoriach okolo 10cm nov\u00e9ho prachov\u00e9ho snehu, ktor\u00fd padal pri miernom vetre, to znamen\u00e1 \u017ee je rozmiestnen\u00fd rovnomerne. V\u00edkendov\u00e9 predpovede hovoria o\u00a0silnom sne\u017een\u00ed, vetre a\u00a0klesaj\u00facej teplote. Pri tak\u00fdchto parametroch je tendencia lav\u00ednov\u00e9ho nebezpe\u010denstva st\u00fapaj\u00faca.
