Nevihte, strele in piši na vodi: kaj storiti
Nazadnje preverjeno:
Korak za korakom
Ukrepajte ob prvem znaku
Temni oblaki, postopno naraščanje vetra ali valov ali nenadna sprememba smeri vetra pomenijo, da se morda bliža nevihta. Če slišite grmenje, ste dovolj blizu, da vas lahko zadene strela. Takoj plujte proti pristanišču ali varnemu zavetju.[12][22][14][1][25]
Reševalni jopiči za vse
Sunki vetra iz nevihte lahko prevrnejo majhno plovilo. Poskrbite, da vsi na krovu takoj nosijo reševalni jopič.[9][18]
Upočasnite in zavarujte plovilo
Zmanjšajte hitrost, da ohranite nadzor. Pospravite opremo, ki se lahko premika, posadka pa naj sedi nizko in na sredini plovila.[18][19]
Na mali jadrnici ob sunkih popustite jadra
Ko udari nenaden sunek vetra, popustite flok in glavno jadro, dokler se jadrnica ne začne vzravnavati.[21]
Pojdite noter ali se spustite nizko
Če ima vaše plovilo kabino, ostanite v njej. Če je nima, počepnite čim niže na sredini plovila.[2][13][10]
Stran od kovine in vode
Izogibajte se kovinskim delom in električnim napravam in se ne dotikajte dveh ozemljenih kovinskih predmetov hkrati. Roke in noge imejte v plovilu.[10][2][5]
Spustite anteno; radio le za nujne primere
Spustite ali privežite radijsko anteno in druge visoke dele, če niso del sistema za zaščito pred strelo. Radia ne uporabljajte, razen v nujnem primeru.[6][16]
Ne morete do obale? Počakajte, da mine
Če se ne morete vrniti na kopno, US National Weather Service svetuje, da spustite sidro in se spustite čim niže. Nevihte so običajno kratke, zato je bolje počakati, da mine, kot pa pluti skozi njo.[15][3]
Če koga zadene strela
Takoj pokličite pomoč. Oseba, ki jo je zadela strela, ne nosi električnega naboja, zato se je varno dotakniti in ji pomagati.[20][7]
Po nevihti preverite plovilo
Če je strela zadela plovilo ali mislite, da ga je, preverite, ali sta električni sistem in kompas poškodovana, preden se zanesete nanju.[8]
Ne
- Z vrnitvijo ne čakajte na grmenje ali dež. Strela lahko udari mnogo milj pred nevihto.[4][14]
- Ne izplujte, če so napovedane nevihte.[1]
- Ne dotikajte se hkrati več kot enega ozemljenega kovinskega predmeta.[10]
- Ne držite rok ali nog v vodi.[5]
- Med strelami ne uporabljajte radia za klepet; prihranite ga za nujne primere.[16]
Pred izplutjem
- Pred odhodom: v pomorski napovedi in opozorilih preverite, ali so omenjene nevihte ali piši.[24][1]
- Pred odhodom: ne pozabite, da so sunki vetra lahko 40 % močnejši od napovedane povprečne hitrosti vetra, v nevihti pa še močnejši.[23]
- Pred odhodom: načrtujte pot umika in na karti preverite, kje se lahko zatečete v zavetje.[11][26]
- Na vodi: redno spremljajte vremenska obvestila na pomorskem radiu.[27]
Pogosta vprašanja
Je med strelami v čolnu varno?
Nobeno plovilo ni povsem varno. Plovilo s kabino je boljše: ostanite v njej, stran od kovine in električnih naprav. V odprtem čolnu počepnite čim niže na sredini, stran od kovinskih delov.
Kako blizu mora biti nevihta, da je strela nevarna?
Če slišite grmenje, ste dovolj blizu, da vas lahko zadene strela. Prvi udar lahko pride z jasnega neba mnogo milj pred nevihtnim oblakom.
Kdaj je po nevihti varno spet izpluti?
US National Weather Service svetuje, da po zadnjem grmenju počakate 30 minut, preden se vrnete k dejavnostim na prostem. Nevihte so običajno kratke, zato je čakanje varnejša izbira.
Ali lahko med nevihto uporabljam VHF radio?
Dokler so naokoli strele, radio prihranite za nujne primere in spustite anteno, če ni del sistema za zaščito pred strelo. Če ste v nevarnosti, pokličite pomoč na kanalu 16.
Kateri so opozorilni znaki piša?
Temni, grozeči oblaki, postopno naraščanje vetra ali valov, nenadna sprememba hitrosti ali smeri vetra in veter, ki piha proti močnemu toku.

- US National Weather Service (NOAA) (2026-10-14): “It is therefore strongly recommended you do not venture out if thunderstorms are a possibility. If you do venture out and recognize thunderstorms nearby, head to port or safe shelter as quickly as possible.”
- US National Weather Service (NOAA) (2026-10-14): “If your boat has a cabin, then stay inside and avoid touching metal or electrical devices. If your boat doesn't have a cabin, stay as low as you can in the boat.”
- US National Weather Service (NOAA) (2026-10-14): “Keep in mind that thunderstorms are usually brief so waiting it out is better than riding it out.”
- US National Weather Service (NOAA) (2026-10-14): “Stop all activities when there is lightning or when weather conditions look threatening. The first lightning strike can come out of a clear blue sky many miles ahead of an approaching thunderstorm cloud.”
- US National Weather Service (NOAA) (2026-10-14): “Keep arms and legs in the boat. Do not dangle them in the water. Water conducts electricity from lightning.”
