Jarn\u00e9 a tepl\u00e9 po\u010dasie so sebou ka\u017edoro\u010dne prin\u00e1\u0161a riziko vzniku n\u00e1tr\u017e\u00ed, mokr\u00fdch a aj z\u00e1kladov\u00fdch lav\u00edn. Ve\u013ek\u00fa pozornos\u0165 vzbudila pomerne ve\u013ek\u00e1 lav\u00edna v \u017diarskej doline, ktor\u00e1 svoj\u00edm dosahom zasiahla pr\u00edstupov\u00fa cestu na \u017diarsku chatu a ohrozila tak turistov v jednej z najnav\u0161tevovanej\u0161\u00edch dol\u00edn Z\u00e1padn\u00fdch Tatier. Odtrhla sa 17.04.2023 o 13:28 z mas\u00edvu Pr\u00edslopu na jeho v\u00fdchodnom svahu. Tak\u00fdto jav nie je ni\u010d\u00edm v\u00fdnimo\u010dn\u00fdm a v minulosti sa v danej lokalite objavilo viacero, \u010di u\u017e jarn\u00fdch mokr\u00fdch lav\u00edn, ale aj ve\u013ek\u00fdch prachov\u00fdch v strede zimy. Pri tejto lav\u00edne je zauj\u00edmav\u00fd fakt, \u017ee jej vzniku nepredch\u00e1dzal \u017eiadny v\u00fdraznej\u0161\u00ed v\u00fdkyv po\u010dasia. Z grafov ni\u017e\u0161ie si m\u00f4\u017eeme v\u0161imn\u00fa\u0165, \u017ee dan\u00fd de\u0148 nebol teplotne v\u00fdrazn\u00fd ako predch\u00e1dzaj\u00face a ani nasleduj\u00face dni. P\u00e1du lav\u00edny trochu nahr\u00e1va, \u017ee predch\u00e1dzaj\u00facu noc v\u00fdrazne nemrzlo. A \u010fal\u0161ie vod\u00edtko by mohol by\u0165 slne\u010dne akt\u00edvny de\u0148, kedy hodnota \u017eiarenia na Pr\u00edslope dosiahla tohoro\u010dn\u00e9 maximum, 1095 w\/m2<\/sup>. Tento rok sme o\u010dak\u00e1vali lav\u00ednu z Pr\u00edslopu, ale sk\u00f4r pri vyhl\u00e1senom 4. stupni lav\u00ednov\u00e9ho nebezpe\u010denstva zo za\u010diatku febru\u00e1ra ako v polovici marca. Ke\u010f sa ale na centr\u00e1lny svah Pr\u00edslopu pozrieme pozornej\u0161ie, m\u00f4\u017eeme si v\u0161imn\u00fa\u0165 mno\u017estvo n\u00e1tr\u017e\u00ed v celom jeho profile a v r\u00f4znych sektoroch. Tie sa objavili u\u017e pribli\u017ene pred mesiacom, kedy do h\u00f4r pri\u0161lo prv\u00e9 v\u00fdraznej\u0161ie oteplenie. To je znak, \u017ee pri v\u00fdraznej zmene po\u010dasia, hlavne oteplen\u00ed a silnej\u0161\u00edch da\u017e\u010foch, sa obdobn\u00e1 situ\u00e1cia m\u00f4\u017ee vyskytn\u00fa\u0165 op\u00e4\u0165. A ke\u010f\u017ee dr\u00e1ha lav\u00edn z centr\u00e1lu Pr\u00edslopu je pln\u00e1 snehu, pr\u00edpadn\u00e9 \u010fal\u0161ie lav\u00edny ba sa len viac rozlievali do \u0161\u00edrky a teda by mohli zasiahnu\u0165 cestu vo v\u00e4\u010d\u0161om rozsahu.<\/p>\n\n\n\n

Preto \u017eiadame n\u00e1v\u0161tevn\u00edkov, aby pri prechode dolinou boli obozretn\u00fd a zbyto\u010dne sa nezdr\u017eiavali v danom \u00faseku ani na \u010fal\u0161\u00edch miestach, ktor\u00e9 s\u00fa otvoren\u00e9 a \u013eahko pr\u00edstupn\u00e9 lav\u00ednam aj z ostatn\u00fdch svahov.<\/strong> <\/p>\n\n\n\n

    Lav\u00edny podobn\u00e9ho charakteru sa objavuj\u00fa aj v in\u00fdch \u010dastiach na\u0161ich h\u00f4r.

Potrv\u00e1 a\u017e do otvorenia letnej turistickej sez\u00f3ny. Jedin\u00fa v\u00fdnimku tvoria pr\u00edstupov\u00e9 trasy na vysokohorsk\u00e9 chaty a do konca apr\u00edla aj oblas\u0165 Chopku v N\u00edzkych Tatr\u00e1ch. Napriek tomu, \u017ee v Tatr\u00e1ch je snehu st\u00e1le dostatok, jeho firnov\u00fa podobu a ub\u00fadanie m\u00f4\u017eeme sledova\u0165 len pomocou kamier na meteorologick\u00fdch staniciach. \u010eal\u0161\u00edm m\u00ed\u013enikom prich\u00e1dzaj\u00facej jari bol aj pretek, ktor\u00fd na Slovensku nem\u00e1 obdoby. Kombinuje beh po zelen\u00fdch l\u00fakach, bike, skialp, freeride a kajak na vode. A to v\u0161etko na jednom mieste, na Liptov Ride. Stredisko lav\u00ednovej prevencie bolo v r\u00e1mci sekcie freeride po\u017eiadan\u00e9 o spolupr\u00e1cu a pos\u00fadenie svahov pre zjazd do Lukovsk\u00e9ho kotla. Snehu v N\u00edzkych Tatr\u00e1ch je tento rok mierne nadpriemer a testy stability na v\u00fdchodn\u00fdch svahoch Chopku zatia\u013e nevykazuj\u00fa zn\u00e1mky nestability. Po\u010dasiu ale nerozk\u00e1\u017ee\u0161 a v de\u0148 preteku sa zjazd uskuto\u010dnil len na zjazdovke, ke\u010f\u017ee v oblasti Chopku pretrv\u00e1valo hmlist\u00e9 po\u010dasie s n\u00edzkou obla\u010dnos\u0165ou.<\/p>\n\n\n\n

Na t\u00fdch sa u\u017e ale tento rok nepoly\u017eujeme a tak hor sa na skalky, natr\u00e9nova\u0165 na nadch\u00e1dzaj\u00facu letn\u00fa lezeck\u00fa a turistick\u00fa sez\u00f3nu. <\/p>\n\n\n\n
