Uplynul\u00fd t\u00fd\u017ede\u0148 sa z poh\u013eadu po\u010dasia a snehu niesol hlavne v znamen\u00ed chladn\u00e9ho arktick\u00e9ho vzduchu a hlbok\u00e9ho prachov\u00e9ho snehu.

V\u010faka chladn\u00e9mu vzduchu a v\u00fddatnej peri\u00f3de sne\u017eenia z predminul\u00e9ho t\u00fd\u017ed\u0148a si snehov\u00e1 pokr\u00fdvka dlho udr\u017eiavala prachov\u00fd charakter. Na jednej strane to boli v\u00fdborn\u00e9 ly\u017eova\u010dky, na strane druhej nebezpe\u010dn\u00e1 lav\u00ednov\u00e1 situ\u00e1cia a takmer nemo\u017en\u00fd \u00famorn\u00fd pohyb aj na \u0161irok\u00fdch ly\u017eiach. Novo napadnut\u00fd sneh nemal po v\u00e4\u010d\u0161ine pevn\u00fd z\u00e1klad, a tak sa ly\u017ee borili aj meter hlboko a obrusovali kamene a \u010du\u010doriedky. Zatia\u013e \u010do v Z\u00e1padn\u00fdch Tatr\u00e1ch napadlo cez 1 meter nov\u00e9ho snehu, v N\u00edzkych Tatr\u00e1ch to a\u017e tak\u00e9 v\u00fdrazn\u00e9 nebolo. Napriek tomu si ly\u017eiari viac pochva\u013eovali N\u00edzke Tatry. D\u00f4vod bol ten, \u017ee v hlbokom pra\u0161ane potrebujete na zjazd aspo\u0148 35\u00b0 sklon, \u010do ale pri zv\u00fd\u0161enom lav\u00ednovom stupni bolo viac odv\u00e1\u017ene ako m\u00fadre. A tak sme v dolin\u00e1ch N\u00edzkych Tatier mohli stretn\u00fa\u0165 viac \u013eud\u00ed ako cez pekn\u00fd v\u00edkendov\u00fd de\u0148 na \u017diarskej chate. <\/p>\n\n\n\n

V\u00fdborn\u00e9 snehov\u00e9 podmienky v kombin\u00e1cii s mno\u017estvom skialpinistov a snoubordistov v ter\u00e9ne priniesli aj lav\u00ednov\u00e9 situ\u00e1cie. E\u0161te po\u010das v\u00edkendu vypadla po jazde Snowboardistov a skialpinistov lav\u00edna z Ve\u013ek\u00e9ho Kriv\u00e1\u0148a v Malej Fatre. Pre spustenie lav\u00edny v tak\u00fdchto podmienkach bolo potrebn\u00e9 ve\u013ek\u00e9 dodato\u010dn\u00e9 za\u0165a\u017eenie prida\u0165 na konkr\u00e9tnom mieste. V tomto pr\u00edpade v konvexnom svahu, teda na jeho hornom zlome. Niekto na\u0161\u0165astie nebol lav\u00ednou zasiahnut\u00fd.<\/p>\n\n\n\n

Aj ke\u010f chladn\u00e9 po\u010dasie pretrv\u00e1valo a\u017e do pondelka, zv\u00fd\u0161en\u00fd lav\u00ednov\u00fd stupe\u0148 n\u00e1m definit\u00edvne uzatvoril v\u00edkend. Mno\u017estvo snehu a jeho v\u00e1ha stla\u010dili snehov\u00fa pokr\u00fdvku nato\u013eko, \u017ee nebezpe\u010denstvo kleslo na mierne, teda 2. Dokazovali to aj snehov\u00e9 profily a kompresn\u00e9 testy. \u00dapln\u00fa bodku za pra\u0161anov\u00fdmi ly\u017eova\u010dkami priniesol tepl\u00fd ju\u017en\u00fd vietor. Ten do na\u0161ich h\u00f4r priniesol v\u00fdrazn\u00e9 oteplenie a behom 24 hod\u00edn sa oteplilo aj o viac ako 10\u00b0C. To snehov\u00fa pokr\u00fdvku zna\u010dne stabilizovalo a tak sa kone\u010dne dali podnika\u0165 t\u00fary aj do vy\u0161\u0161\u00edch pol\u00f4h Tatier. Povrch za\u010dal by\u0165 na v\u00e4\u010d\u0161ine \u00fazemia doskovit\u00fd a nosn\u00fd. Plat\u00ed to ale ve\u013emi lok\u00e1lne. Zatia\u013e \u010do na n\u00e1vetern\u00fdch svahoch hlavne z\u00e1padn\u00fdch a\u017e severn\u00fdch orient\u00e1ci\u00ed je podklad \u013eadov\u00fd a tr\u00e1vnat\u00fd, naopak na z\u00e1vetern\u00fdch ju\u017en\u00fdch svahoch je v \u017e\u013eaboch a muld\u00e1ch ulo\u017een\u00fdch viac ako 2 metre snehu. Vo Ve\u013ekej Fatre sa v p\u00e1sme lesa dokonca vytvorila aj \u013eadov\u00e1 krusta, ktor\u00e1 zmrazila \u00fasmev v\u0161etk\u00fdm skialpinistom.<\/p>\n\n\n\n

Posledn\u00fa dobu si mus\u00edme zvyka\u0165 na to, \u017ee po\u010dasie v hor\u00e1ch je ako na hojda\u010dke. Odzrkad\u013euje to aj tento t\u00fd\u017ede\u0148. Zatia\u013e \u010do za\u010diatok bol extr\u00e9mne chladn\u00fd, jeho koniec je extr\u00e9mne tepl\u00fd. Izoterma nula sa pohybuje v nadmorskej v\u00fd\u0161ke okolo 1500 m.n.m. Po t\u00fato hranicu s\u00fa zr\u00e1\u017eky preva\u017ene vo forme da\u017e\u010fa. Naopak vo vysok\u00fdch poloh\u00e1ch sne\u017e\u00ed, ale lav\u00ednov\u00fa situ\u00e1ciu komplikuje b\u00farliv\u00fd vietor so silou v\u00edchrice. Lomnick\u00fd \u0161t\u00edt dnes nameral vietor v n\u00e1razoch o sile 33 m\/s, \u010do predstavuje okolo 120 km\/h. Nadch\u00e1dzaj\u00faci v\u00edkend sa po\u010dasie v\u00fdrazne meni\u0165 nem\u00e1. M\u00f4\u017eeme tak o\u010dak\u00e1va\u0165, \u017ee zv\u00fd\u0161en\u00fd 3. lav\u00ednov\u00fd stupe\u0148 bude vyhl\u00e1sen\u00fd op\u00e4\u0165. No tentokr\u00e1t ve\u013emi lok\u00e1lne a hlavne v severn\u00fdch orient\u00e1ci\u00e1ch. Pevne d\u00fafame, \u017ee d\u00e1\u017e\u010f n\u00e1m t\u00fa trochu snehu, ktor\u00fa v dolin\u00e1ch m\u00e1me, \u00faplne nevyma\u017ee.<\/p>\n\n\n\n
