Po\u010dasie, sneh a lav\u00edny 21 – 27. janu\u00e1ra 2023<\/strong><\/p>\n\n\n\n

Ke\u010f predch\u00e1dzaj\u00faci t\u00fd\u017ede\u0148 napadlo v horstv\u00e1ch Slovenska od 40 do 70cm nov\u00e9ho snehu, tento t\u00fd\u017ede\u0148 za\u017eili hory presn\u00fd opak. Po\u010das t\u00fd\u017ed\u0148a sme nezaznamenali \u017eiadne zr\u00e1\u017eky. Prekvapil n\u00e1s pr\u00edjemn\u00fdm slne\u010dn\u00fdm a hlavne z poh\u013eadu obla\u010dnosti inverzn\u00fdm po\u010das\u00edm. Koncom minul\u00e9ho t\u00fd\u017ed\u0148a doznievali nebezpe\u010dn\u00e9 lav\u00ednov\u00e9 podmienky z poslednej peri\u00f3dy sne\u017eenia a snehov\u00e1 pokr\u00fdvka sa za\u010d\u00ednala postupne stabilizova\u0165. No ako to spravidla b\u00fdva, najviac lav\u00ednov\u00fdch neh\u00f4d sa st\u00e1va prv\u00fd pekn\u00fd de\u0148 po v\u00fddatnom sne\u017een\u00ed. A tak sme v sobotu 21. janu\u00e1ra 2023 zaznamenali \u010fal\u0161iu lav\u00ednov\u00fa nehodu. Na\u0161\u0165astie so \u0161\u0165astn\u00fdm koncom, aj ke\u010f s hrozivo vyzeraj\u00facim odtrhom a d\u013a\u017ekou lav\u00edny. Nehoda sa stala v Malej Fatre pod Ve\u013ek\u00fdm Kriv\u00e1\u0148om. Definova\u0165 by sme ju mohli ako nehoda s VE\u013dK\u00ddM DODATO\u010cN\u00ddM ZA\u0164A\u017dEN\u00cdM. Teda dvaja ly\u017eiari s\u00fa\u010dasne v lav\u00ednovom svahu. Viac o tejto nehode si m\u00f4\u017eete pre\u010d\u00edta\u0165 v samostatnom blogu: Lav\u00ednov\u00e1 nehoda pod Ve\u013ek\u00fdm Kriv\u00e1\u0148om v Malej Fatre, 21. janu\u00e1ra 2023<\/a>.<\/p>\n\n\n\n

Cel\u00fd pracovn\u00fd t\u00fd\u017ede\u0148 prevl\u00e1dalo v hor\u00e1ch jasn\u00e9 a slne\u010dn\u00e9 po\u010dasie s inverznou obla\u010dnos\u0165ou. Z malej \u010dasti m\u00f4\u017eeme hovori\u0165 aj o inverznej teplote, ale t\u00e1 nebola tentokr\u00e1t tak\u00e1 v\u00fdrazn\u00e1 ako b\u00fdva zvykom. Najviac sa prejavila pr\u00e1ve v utorok 24. janu\u00e1ra, kedy rozdiel tepl\u00f4t v nadmorskej v\u00fd\u0161ke 1300 vs. 1800 m n. m. bol necel\u00fdch 8\u00b0C. N\u00edzka obla\u010dnos\u0165 tieto dni kulminovala od v\u00fd\u0161ky 1000 a\u017e do 1600 m n. m. a to hlavne v druhej polovici t\u00fd\u017ed\u0148a.<\/p>\n\n\n\n

Tak\u00e9to pekn\u00e9 slne\u010dn\u00e9 po\u010dasie malo v\u00fdrazn\u00fd vplyv na stabiliz\u00e1ciu snehovej pokr\u00fdvky. Na ju\u017ene orientovan\u00fdch a slnkom nasvieten\u00fdch svahoch sa sneh po\u010das d\u0148a nat\u00e1pal a po\u010das noci sa na nich tvorila slab\u00e1 a\u017e stredne siln\u00e1 firnov\u00e1 k\u00f4ra. Objavilo sa aj nieko\u013eko mal\u00fdch lav\u00edn z mokr\u00e9ho snehu, pri ktor\u00fdch vzniku bol bodov\u00fd odtrh v slnkom nahriatych strm\u00fdch skaln\u00fdch sten\u00e1ch. Nieko\u013eko n\u00e1tr\u017e\u00ed a z\u00e1kladov\u00fdch lav\u00edn sa uk\u00e1zalo aj na svahoch, kde je tr\u00e1vnat\u00fd klzk\u00fd povrch a v\u00fd\u0161ka snehu nedosahuje ani priemern\u00e9 zimn\u00e9 hodnoty. Naopak, v\u010faka inverzii sa v lesoch a po ich horn\u00fa hranicu st\u00e1le nach\u00e1dza such\u00fd prachov\u00fd sneh, \u010dasto aj s povrchovou inova\u0165ou. A \u010do severn\u00e9 orient\u00e1cie? Tu sa snehov\u00e1 pokr\u00fdvka tie\u017e v\u00fdrazne stabilizovala, no o pra\u0161ane nem\u00f4\u017ee by\u0165 ani re\u010d. Nach\u00e1dzaj\u00fa sa tu zv\u00e4\u010d\u0161a vetrom vytvoren\u00e9 dosky a vank\u00fa\u0161e r\u00f4znej hr\u00fabky a tvrdosti. Na ly\u017eiach nosn\u00e9, ale pri pe\u0161om pohybe sa preb\u00e1raj\u00fa do ni\u017e\u0161\u00edch m\u00e4kk\u00fdch vrstiev. Aj preto vo v\u0161etk\u00fdch pohoriach od za\u010diatku t\u00fd\u017ed\u0148a trv\u00e1 MIERNE lav\u00ednov\u00e9 nebezpe\u010denstvo. A s predpove\u010fou po\u010dasia na nadch\u00e1dzaj\u00faci v\u00edkend sa zrejme toho ve\u013ea nezmen\u00ed. Na\u010falej plat\u00ed, \u017ee lav\u00ednu je mo\u017en\u00e9 uvo\u013eni\u0165 hlavne pri VE\u013dKOM DODATO\u010cNOM ZA\u0164A\u017dEN\u00cd<\/strong>!<\/p>\n\n\n\n

Koniec t\u00fd\u017ed\u0148a n\u00e1m priniesol aj nieko\u013eko zauj\u00edmav\u00fdch meteorologick\u00fdch javov.
