V stredu r\u00e1no bolo tepl\u00e9 slne\u010dn\u00e9 po\u010dasie, r\u00e1no nemrzlo ani a Lomnickom \u0161t\u00edte, denn\u00e9 teploty dosahovali maxim\u00e1 v poobed\u0148aj\u0161\u00edch hodin\u00e1ch, kde najni\u017e\u0161ia teplota bola +3\u00b0C, v 2000 m n.n.m. a\u017e +5\u00b0C. Toto ist\u00e9 sa odohralo vo \u0161tvrtok, samozrejme bez no\u010dn\u00e9ho ochladenia, ktor\u00e9 je pre jarn\u00e9 po\u010dasie charakteristick\u00e9. Ve\u013ek\u00e1 noc v\u0161ak mala in\u00e9 pl\u00e1ny.

Tieto v\u0161etky udalosti mali v\u00fdznamn\u00fd vplyv aj na lav\u00ednov\u00fa situ\u00e1ciu u n\u00e1s. Pondelkov\u00e1 a utorkov\u00e1 situ\u00e1cia sa niesla okolo pred v\u00edkendov\u00e9ho probl\u00e9mu – trval\u00e1 slab\u00e1 vrstva. V snehovej pokr\u00fdvke sa nach\u00e1dzala na tvrdej firnovej vrstve kritick\u00e1 vrstva hranatozrnn\u00e9ho snehu. Tento \u0165a\u017eko identifikovate\u013en\u00fd probl\u00e9m sa nach\u00e1dzal v h\u013abke 15 a\u017e 60 cm pod povrchom snehovej pokr\u00fdvky. Samovo\u013en\u00e9 splazy a mal\u00e9 lav\u00edny sa neo\u010dak\u00e1vali nako\u013eko povrch snehu bol na v\u00e4\u010d\u0161ine svahov tvrd\u00fd a nosn\u00fd. Oteplenie v utorkovej noci sa uk\u00e1zalo v predobedn\u00fdch hodin\u00e1ch stredy. Vysok\u00e1 teplota a siln\u00e9 slne\u010dn\u00e9 \u017eiarenie sp\u00f4sobili zn\u00ed\u017eenie stability snehovej pokr\u00fdvky na svahoch v\u0161etk\u00fdch orient\u00e1ci\u00ed. Samozrejme doobeda to boli hlavne v\u00fdchodn\u00e9, poobede juhoz\u00e1padn\u00e9. Zaznamenali sme zv\u00fd\u0161en\u00fa lav\u00ednov\u00fa aktivitu, kde i\u0161lo hlavne o lav\u00edny z mokr\u00e9ho vo\u013en\u00e9ho snehu a mokr\u00e9 doskov\u00e9 lav\u00edny. Pod\u013ea inform\u00e1ci\u00ed v\u0161etky spont\u00e1nne tzn. samovo\u013en\u00e9. Nasledovala tepl\u00e1 noc a \u0161tvrtok bol takisto tepl\u00fd, slne\u010dn\u00fd a lav\u00ednov\u00fd. Povrch snehu bol na v\u0161etk\u00fdch slnkom vysvieten\u00fdch svahoch vlhk\u00fd a\u017e mokr\u00fd, v tieni sa odtopila len vrchn\u00e1 vrstva, miestami v najvy\u0161\u0161\u00edch poloh\u00e1ch bolo tvrdo. V najvy\u0161\u0161\u00edch poloh\u00e1ch, hlavne severn\u00e9ho sektoru sa st\u00e1le napriek jarnej situ\u00e1ci\u00ed vyskytuje nebezpe\u010dn\u00e1 vrstva hranatozrnn\u00e9ho snehu. <\/p>\n\n\n\n

    Dnes r\u00e1no na hor\u00e1ch prevl\u00e1dala hmla, zr\u00e1\u017eky od 1700 m n.m. snehov\u00e9. Po\u010das noci napadlo do 10 cm nov\u00e9ho snehu miestami vo forme kr\u00fapkov, ktor\u00fd v\u0161ak stihol vietor poupratova\u0165 hlavne na z\u00e1vetern\u00e9 J, JV svahy.
