V ju\u017enej stene Lomnick\u00e9ho \u0161t\u00edtu sa v Motykovej ceste striedali z\u00e1stupy \u013eud\u00ed nato\u013eko, a\u017e po p\u00e1r d\u0148och bolo po podmienke. Rovnako v\u00fdborn\u00e9 lezeck\u00e9 t\u00fary sa dali podnika\u0165 takmer na ka\u017ed\u00fd vrchol. V\u00edkend n\u00e1m priniesol kr\u00e1sne slne\u010dn\u00e9 a v nede\u013eu aj tepl\u00e9 po\u010dasie. Teplota vo v\u00fd\u0161ke 2000 mn.m. sa pohybovala okolo -3\u00b0C. T\u00e1 trocha vo\u013en\u00e9ho snehu, ktor\u00e1 sa nach\u00e1dzala ve\u013emi lok\u00e1lne v z\u00e1vetriach ju\u017en\u00fdch a\u017e v\u00fdchodn\u00fdch orient\u00e1ci\u00ed, za\u010dal pomaly vlhn\u00fa\u0165 hlavne v poobed\u0148aj\u0161\u00edch hodin\u00e1ch.

V Pondelok k n\u00e1m za\u010dal od severoz\u00e1padu pr\u00fadi\u0165 studen\u00fd front, p\u00f4vodom Arktick\u00fd morsk\u00fd vzduch, ktor\u00fd do na\u0161ich h\u00f4r priniesol nielen snehov\u00e9 zr\u00e1\u017eky, ale v prvom rade siln\u00fd vietor. V\u00edchricu! N\u00e1razy vetra na stanici AMS \u013dadov\u00e9 pleso dosahovali r\u00fdchlos\u0165 47,7 m\/s, \u010do predstavuje vietor o r\u00fdchlosti 170 km\/h. Bolo \u00faplne jasn\u00e9, kde skon\u010d\u00ed v\u00e4\u010d\u0161ina snehu. V lese a kosodrevine. V\u0161etci sme pevne d\u00fafali, \u017ee sne\u017eenie bude o \u010dosi v\u00fdraznej\u0161ie. V\u00e4\u010d\u0161ina pohor\u00ed dostala n\u00e1dielku okolo 10 cm, najviac v\u0161ak schytala Mal\u00e1 Fatra a Z\u00e1padn\u00e9 Tatry, kde nasne\u017eilo do 20 cm. V tieto a nasleduj\u00face dni bol pre vrcholov\u00e9 partie v\u0161etk\u00fdch pohor\u00ed vyhl\u00e1sen\u00fd zv\u00fd\u0161en\u00fd 3. lav\u00ednov\u00fd stupe\u0148. Z\u00e1sadn\u00fd lav\u00ednov\u00fd probl\u00e9m bol vetrom previaty sneh, ktor\u00fd napadol na tvrd\u00fd a\u017e \u013eadov\u00fd podklad, s ktor\u00fdm mal len minim\u00e1lnu s\u00fadr\u017enos\u0165. Kv\u00f4li vetru bol teda sneh previaty na z\u00e1vetern\u00e9 strany op\u00e4\u0165 hlavne juhov\u00fdchodn\u00fdch a\u017e v\u00fdchodn\u00fdch orient\u00e1ci\u00ed. Snehov\u00e9 dosky a vank\u00fa\u0161e, ktor\u00e9 dosahovali hr\u00fabku okolo 1m, sa ale vyskytovali aj na svahoch ostatn\u00fdch orient\u00e1ci\u00ed. Hlavne na miestach, kde typ a tvar ter\u00e9nu vytv\u00e1ra z\u00e1vetrie. Teda hlavne pod hrebe\u0148mi, skaln\u00fdmi stenami, v \u00fazkych \u017e\u013eaboch a muld\u00e1ch.<\/p>\n\n\n\n

V stredu prich\u00e1dza v\u00fdrazn\u00e1 zmena po\u010dasia. Po studenom fronte sa na celom \u00fazem\u00ed vytvor\u00ed tlakov\u00e1 v\u00fd\u0161 a s \u0148ou spojen\u00e9 pekn\u00e9 a slne\u010dn\u00e9 po\u010dasie. St\u00e1le plat\u00ed 3. lav\u00ednov\u00fd stupe\u0148, no napriek tomu je, napr\u00edklad, \u017diarska dolina pln\u00e1 skialpinistov a poly\u017eovan\u00e9 s\u00fa takmer v\u0161etky ju\u017en\u00e9 svahy. Testy stability snehovej pokr\u00fdvky vykazuj\u00fa nebezpe\u010dn\u00fa vrstvu hranatozrnn\u00e9ho snehu, ktor\u00e1 sa nerovnomerne, tak ako naviaty sneh, nach\u00e1dza v r\u00f4znych h\u013abkach. Tam kde je v h\u013abke aspo\u0148 50 cm, nevykazuje zn\u00e1mky nestability. No pokia\u013e sa nadlo\u017en\u00e1 vrstva zmen\u0161uje, u\u017e pri h\u013abke 25 cm je test v\u00fdrazne podozriv\u00fd a\u017e nebezpe\u010dn\u00fd. To znamen\u00e1, \u017ee tak ako s\u00fa lok\u00e1lne snehov\u00e9 vank\u00fa\u0161e, tak lok\u00e1lne je aj lav\u00ednov\u00e9 nebezpe\u010denstvo. Pr\u00edkladom je bohu\u017eia\u013e aj lav\u00ednov\u00e1 nehoda z Kamenistej doliny, ktor\u00e1 sa pre jedn\u00e9ho z trojice skialpinistov skon\u010dila tragicky.

T\u00fd\u017ede\u0148 sa n\u00e1m op\u00e4\u0165 kon\u010d\u00ed studen\u00fdm frontom. A op\u00e4\u0165 so siln\u00fdm severoz\u00e1padn\u00fdm vetrom do 20 m\/s. 3. lav\u00ednov\u00fd stupe\u0148 pretrv\u00e1va na\u010falej. V nadch\u00e1dzaj\u00facich d\u0148och sa po\u010dasie v\u00fdrazne meni\u0165 nebude. Do soboty m\u00e1 pokra\u010dova\u0165 sne\u017eenie, ktor\u00e9 zatia\u013e prinieslo do 15 cm snehu a znovu hlavne v Malej Fatre a Z\u00e1padn\u00fdch Tatr\u00e1ch. Teda lav\u00ednov\u00e1 situ\u00e1cia sa v\u00fdrazne meni\u0165 nebude, 3. stupe\u0148 pravdepodobne uzavrie aj v\u00edkend. <\/p>\n\n\n\n

Najv\u00e4\u010d\u0161\u00ed pozor si d\u00e1vajte v prv\u00fd pekn\u00fd de\u0148 po sne\u017een\u00ed a silnom vetre, ktor\u00fd sa pod\u013ea predpovede vytvor\u00ed v nede\u013eu!<\/strong><\/p>\n\n\n\n
