Napriek tomu, \u017ee za\u010diatkom marce to u\u017e u\u017e vyzeralo, \u017ee zima n\u00e1m ide skon\u010di\u0165<\/a>, v predposledn\u00fd marcov\u00fd t\u00fd\u017ede\u0148 uk\u00e1zala op\u00e4\u0165 svoju silu.

U\u017e v sobotu 13.3.2021 sme zaznamenali lav\u00ednov\u00fa nehodu v Malej Fatre na Pekeln\u00edku<\/a>. \u010eal\u0161ia lav\u00ednov\u00e1 nehoda nenechala na seba dlho \u010daka\u0165 a bola zaznamenan\u00e1 v nede\u013eu 14.3.2021 vo Vysok\u00fdch Tatr\u00e1ch na Prednom Solisku<\/a>. Obe lav\u00ednov\u00e9 nehody sa stali na v\u00fdchodn\u00fdch orient\u00e1ci\u00e1ch po ve\u013ekom dodato\u010dnom za\u0165a\u017een\u00ed, obe s\u00edce s \u0165a\u017ek\u00fdmi zraneniami ale bez obet\u00ed.<\/p>\n\n\n\n

Ako vidie\u0165 z grafu vy\u0161\u0161ie, cez v\u00edkend bolo naozaj veterno. Napr\u00edklad sila vetra na Lomnickom \u0161t\u00edte dosahovala v sobotu r\u00fdchlos\u0165 30m\/s v n\u00e1razoch (108 km\/h), a tak sa nemo\u017eno \u010dudova\u0165, \u017ee ulo\u017eila sneh na z\u00e1vetern\u00fdch orient\u00e1ci\u00e1ch do nebezpe\u010dn\u00fdch dosiek. <\/p>\n\n\n\n

V pondelok do poludnia pretrv\u00e1valo poloobla\u010dn\u00e9 po\u010dasie a v stredn\u00fdch poloh\u00e1ch sa za\u010dal sneh prer\u00e1ba\u0165 a sada\u0165. Netrvalo to v\u0161ak dlho a od poludnia sa za\u010dal do na\u0161ich horsk\u00fdch oblast\u00ed nas\u00fava\u0165 studen\u00fd vlhk\u00fd vzduch od severoz\u00e1padu. Toto pr\u00fadenie bolo spojen\u00e9 s ve\u013emi siln\u00fdm vetrom a zr\u00e1\u017ekami. Za dvojd\u0148ov\u00fa peri\u00f3du sne\u017eenia sme zaznamenali pr\u00edrastok nov\u00e9ho snehu do 30cm a to najm\u00e4 v Z\u00e1padn\u00fdch a Vysok\u00fdch Tatr\u00e1ch.<\/p>\n\n\n\n

Z grafu m\u00f4\u017eeme vy\u010d\u00edta\u0165, \u017ee pr\u00edrastok snehu na AMS Zamrznut\u00e9 pleso v 2070 m .n.m. bol v priebehu 12 hod\u00edn +50 cm.

Ako bonus prin\u00e1\u0161ame eduka\u010dn\u00e9 video uvo\u013enenia lav\u00edny vo Vysok\u00fdch Tatr\u00e1ch. Uvo\u013enenie lav\u00edny nastalo vo v\u00fd\u0161ke 2040 m na strmom svahu s v\u00fdchodnou orient\u00e1ciou pri ve\u013ekom dodato\u010dnom za\u0165a\u017een\u00ed (pe\u0161\u00ed v\u00fdstup osoby). \u010ciarov\u00fd odtrh doskovej lav\u00edny mal pribli\u017ene 25 metrov.
