Po\u010fme, ale pekne po poriadku. Koncom minul\u00e9ho t\u00fd\u017ed\u0148a vrcholilo oteplenie – tepl\u00fd vlhk\u00fd vzduch sa nad na\u0161e \u00fazemia pres\u00faval z juhu a priniesol zr\u00e1\u017eky vo forme da\u017e\u010fa a\u017e do 1500 m n.m. a niekde aj vy\u0161\u0161ie – snehov\u00e1 pokr\u00fdvka v stredn\u00fdch poloh\u00e1ch sadala a prem\u00e1\u010dala sa. V\u00fdrazn\u00e9 oteplenie aj v najvy\u0161\u0161\u00edch poloh\u00e1ch sp\u00f4sobilo, \u017ee vo viacer\u00fdch horstv\u00e1ch sme evidovali spont\u00e1nne lav\u00edny z tepla. Zo soboty (6.2.2021) na nede\u013eu sme e\u0161te zaznamenali saharsk\u00fd prach, ktor\u00fd sa do na\u0161ich horsk\u00fdch \u00fazem\u00ed dostal vo v\u00fd\u0161kovom juhoz\u00e1padnom pr\u00faden\u00ed. Za\u010diatkom posledn\u00e9ho t\u00fd\u017ed\u0148a ovplyv\u0148ovalo po\u010dasie v horstv\u00e1ch Slovenska front\u00e1lne rozhranie, ktor\u00e9 neust\u00e1le prin\u00e1\u0161alo mierne zr\u00e1\u017eky, vietor , ktor\u00fd sa menil od juhoz\u00e1padu na severoz\u00e1pad. Postupne pri\u0161lo ochladenie, v\u010faka ktor\u00e9mu povrch snehovej pokr\u00fdvky stvrdol. Lav\u00ednov\u00e1 situ\u00e1cia sa stabilizovala, na\u010falej pretrv\u00e1val mierny stupe\u0148 lav\u00ednov\u00e9ho nebezpe\u010denstva.<\/p>\n\n\n\n

Studen\u00fd arktick\u00fd vzduch sa nad na\u0161e \u00fazemie za\u010dal nas\u00fava\u0165 v stredu 11.2.2021 skoro r\u00e1no, pri\u010dom tento jav priniesol zauj\u00edmav\u00fd uk\u00e1\u017ekov\u00fd fenom\u00e9n.

V stredu r\u00e1no preto bolo v z\u00e1padnej \u010dasti na\u0161ich horstiev ove\u013ea ni\u017e\u0161ia teplota ako vo v\u00fdchodnej \u010dasti, a to aj o 1000 m vy\u0161\u0161ie. V Malej Fatre na AMS Snilovsk\u00e9 sedlo (1492 m n.m.) dosiahla r\u00e1no o 06:00 UTC teplota -17\u00b0C, zatia\u013e \u010do vtom istom \u010dase sme na Lomnickom \u0161t\u00edte (2633 m n.m.) namerali teplotu len -10\u00b0C (o 1000m vy\u0161\u0161ie a o 7 stup\u0148ov teplej\u0161ie).<\/p>\n\n\n\n

Zmena vzduchov\u00fdch hm\u00f4t pochopite\u013ene priniesla aj siln\u00fd vietor. Ten kop\u00edroval podb\u00edjanie klinu studen\u00e9ho vzduchu a postupne silnel, v stredu r\u00e1no spo\u010diatku zosilnel len v ni\u017e\u0161\u00edch poloh\u00e1ch a postupne sa pres\u00faval do vy\u0161\u0161\u00edch pol\u00f4h.
