Aj ke\u010f to v\u00a0predminul\u00fd t\u00fd\u017ede\u0148 vyzeralo, \u017ee do h\u00f4r u\u017e zav\u00edtala jar, tento t\u00fd\u017ede\u0148 sa k\u00a0n\u00e1m zima vr\u00e1tila. Za\u010diatkom t\u00fd\u017ed\u0148a prevl\u00e1dalo premenliv\u00e9 po\u010dasie. Preva\u017ene bolo zamra\u010den\u00e9 a hmlisto, ale ob\u010das vykuklo aj slnko. \u00a0Teploty boli relat\u00edvne vysok\u00e9 a stav po\u010dasia pripom\u00ednal Jar. Sneh bol na v\u00e4\u010d\u0161ine miest sadnut\u00fd a\u00a0jeho povrch preva\u017ene\u00a0 k\u00f4rovit\u00fd a\u017e tvrd\u00fd. Prevl\u00e1dal ju\u017en\u00fd vietor a v\u00a0ni\u017e\u0161\u00edch poloh\u00e1ch sa v\u00a0priebehu d\u0148a tak otep\u013eovalo, \u017ee sa tvorila ka\u0161a. V\u00a0utorok sa cel\u00e1 situ\u00e1cia oto\u010dila o\u00a0180 stup\u0148ov. Pri prechode frontu za\u010dalo sne\u017ei\u0165 a\u00a0siln\u00fd severoz\u00e1padn\u00fd vietor na hrebe\u0148och dosahoval v\u00a0n\u00e1razoch aj 100 km\/h. S\u00a0 prest\u00e1vkami sne\u017eilo a\u017e do piatkov\u00e9ho r\u00e1no pri\u010dom za posledn\u00fa peri\u00f3du sne\u017eenia napadlo v\u00a0na\u0161ich hor\u00e1ch nasledovn\u00e9 mno\u017estvo nov\u00e9ho such\u00e9ho snehu: Vysok\u00e9 Tatry: 30 \u2013 50 cm, Z\u00e1padn\u00e9 Tatry 20 \u2013 35 cm, N\u00edzke Tatry 10 \u2013 20 cm, Mal\u00e1 Fatra: 10 -25 cm a\u00a0Ve\u013ek\u00e1 Fatra: do 15 cm. Samozrejme sneh bo vo ve\u013ekej miere previevan\u00fd na z\u00e1vetern\u00e9 svahy preva\u017ene s\u00a0J, JV, V\u00a0a\u00a0SV orient\u00e1ciou.

Pr\u00e1ve naopak je tomu na opa\u010dne orientovan\u00fdch ju\u017en\u00fdch a\u017e severov\u00fdchodn\u00fdch svahoch, kde v\u00fd\u0161ka novo naf\u00fakan\u00e9ho snehu m\u00f4\u017ee dosahova\u0165 a\u017e 1 meter. Tento stav sa t\u00fdka najm\u00e4 vy\u0161\u0161\u00edch pol\u00f4h Vysok\u00fdch a\u00a0Z\u00e1padn\u00fdch Tatier (>1500 m n. m.). Pod touto hranicou je snehov\u00e1 pokr\u00fdvka relat\u00edvne dobre stabilizovan\u00e1.<\/p>\n

V\u00a0priebehu t\u00fd\u017ed\u0148a sme zaznamenali nieko\u013eko doskov\u00fdch lav\u00edn najm\u00e4 na svahoch uveden\u00fdch v\u00a0lav\u00ednovej inform\u00e1cii<\/a>. Niektor\u00e9 z\u00a0nich spadli samovo\u013ene u\u017e na relat\u00edvne mal\u00fdch sklonoch (okolo 30\u00b0), in\u00fdm zas dopomohli skialpinisti, alebo ly\u017eiari. Na kritick\u00fdch svahoch zvy\u010dajne sta\u010dilo u\u017e mal\u00e9 dodato\u010dn\u00e9 za\u0165a\u017eenie. Lav\u00ednov\u00e9 nebezpe\u010denstvo je ve\u013emi lok\u00e1lne a\u00a0situ\u00e1cia sa m\u00f4\u017ee l\u00ed\u0161i\u0165 od svahu ku svahu. Ur\u010dite si treba da\u0165 pozor na miestach, kde je \u010derstv\u00fd sneh ubit\u00fd do dosiek a\u00a0pri prechodoch zo star\u00e9ho tvrd\u00e9ho snehu na vetrom naf\u00fakan\u00e9 vank\u00fa\u0161e. Na slnkom osvieten\u00fdch svahoch sa m\u00f4\u017eu pri oteplen\u00ed vyskytn\u00fa\u0165 aj samovo\u013en\u00e9 lav\u00edny. Tendencia lav\u00ednov\u00e9ho nebezpe\u010denstva je zotrval\u00e1.<\/p>\n

Cez v\u00edkend o\u010dak\u00e1vame polojasno. Ob\u010dasne sa m\u00f4\u017eu vyskytn\u00fa\u0165 preva\u013euj\u00face sa obla\u010dnos\u0165 a\u00a0hmly. Postupne ku koncu v\u00edkendu sa m\u00e1 otep\u013eova\u0165.
