"Ino ndi nthawi yoti tiyambe kukonzekera mavuto omwe angabwere chifukwa cha kusefukira kwa madzi m'mphepete mwa nyanja ndi mtsinje wa Mendenhall."
Malo otchedwa Suicide Basin ayamba kuyenda pamwamba pa dambo lake la ayezi ndipo anthu omwe ali pansi pa Mendenhall Glacier ayenera kukonzekera kusefukira kwa madzi, koma palibe chomwe chikusonyeza kuti kuyambira m'mawa Lachisanu madzi akutuluka kuchokera ku kusefukira kwa madzi, malinga ndi akuluakulu a National Weather Service Juneau.
Chigwachi, chomwe chakhala chikutulutsa madzi chaka chilichonse chotchedwa jökulhlaups kuyambira 2011, chadzaza ndipo "kutsika kwa madzi komwe kumachitika chifukwa cha madzi osefukira m'dambo la ayezi kunapezeka Lachinayi m'mawa," malinga ndi chikalata cha NWS Juneau chomwe chinaperekedwa Lachinayi nthawi ya 11 koloko m'mawa patsamba loyang'anira la Suicide Basin. Chikalatacho chikunena kuti zinatenga masiku asanu ndi limodzi kuchokera nthawi yomwe chigwachi chinadzaza mpaka madzi atatulutsidwa chaka chatha.
"Umboni wa madzi otuluka pansi pa chisanu ukangopezeka, chenjezo la kusefukira kwa madzi lidzaperekedwa," chilengezocho chikutero.
Nkhani yofalitsidwa Lachisanu nthawi ya 9 koloko m'mawa inati "mkhalidwe sunasinthe" tsiku lapitalo.
Andrew Park, katswiri wa zanyengo pa siteshoni yomwe ili pafupi ndi chisanu, adati mu kuyankhulana Lachinayi m'mawa kuti kutayikira kwa madzi "sikutanthauza kuti kutulutsidwa kwa madzi kukuchitika pakadali pano."
"Umenewo ndiye uthenga waukulu - umene tikudziwa kuti ndi wofunika ndipo tikudikira kuti tidziwe zambiri," adatero.
Komabe, kwa anthu m'derali "ino ndi nthawi yoti ayambe kukonzekera zotsatira za kusefukira kwa madzi," lipoti loperekedwa ndi NWS Juneau likutero.
Pofika Lachinayi m'mawa, madzi a Mtsinje wa Mendenhall anali mamita 6.43, poyerekeza ndi mamita pafupifupi anayi kumayambiriro kwa chaka chatha. Koma Park adati chifukwa chachikulu cha kuopsa kwa kusefukira kwa madzi chaka chino chidzakhala momwe madzi amatuluka mwachangu kuchokera m'chidebecho pamene dambo la ayezi likusweka.
“Ngati mwatulutsa madzi pang'ono si vuto kwenikweni,” iye anatero. “Koma tulutsani madzi onsewo nthawi yomweyo, mumakhala ndi mavuto aakulu.”
Bungwe la US Geological Survey linayika zida zatsopano zowunikira pa mlatho wa Mtsinje wa Mendenhall pa Back Loop Road Lachinayi m'mawa kuti zithandize kutsogolera kukonzekera kutulutsa madzi kuti atulutsidwe ku Suicide Basin. Chaka chatha pamene madzi adatulutsidwa pa Ogasiti 5, USGS idadalira kokha gauge yake ya mtsinje wa Mendenhall Lake.
Randy Host, katswiri wa zamadzi ku USGS, anati chiŵerengero cha liwiro chidzalola kuyang'anira madzi osefukira kudzera mumtsinje.
“Idzayesa siteji, yomwe timaitcha kutalika kwa gage, monga kutalika kwa mtsinje,” iye anatero. “Kenako idzayesanso liwiro la pamwamba. Idzayesa liwiro la madzi pamwamba.”
Gawo lalikulu la Mtsinje wa Mendenhall tsopano lili ndi miyala yokwanira kuti ateteze nyumba pambuyo poti kusefukira kwa madzi chaka chatha kunawononga kwambiri gombe la mtsinjewo. Kusefukirako kunawononga pang'ono kapena kwathunthu nyumba zitatu ndipo nyumba zina zoposa makumi atatu zinawonongeka mosiyanasiyana.
Amanda Hatch, yemwe nyumba yake idasefukira ndi madzi okwana mainchesi asanu ndi atatu m'malo osungiramo zinthu chaka chatha, adati kukonzanso kwakukulu kuti ateteze nyumba ya banja lake kwangomalizidwa kumene.
“Sitikuda nkhawa kwambiri chifukwa takweza nyumbayo mamita anayi,” iye anatero. “Koma tili ndi galimoto yamagetsi, kotero ngati itasefukira tidzasuntha galimotoyo mumsewu kupita kunyumba ya mnzathu. Koma takonzeka.”
Malo osungiramo zinthu m'nyumbamo adalimbikitsidwanso kuti atetezedwe ku kusefukira kwa madzi, anatero Hatch. Iye anati inshuwalansi sinalipire kuwonongeka komwe kudachitika chaka chatha, koma thandizo la masoka ndi ndalama zomwe zinafunidwa kudzera mu bungwe la federal Small Business Association zinathandiza kuti kukonza ndi kukonzanso nyumbayo kutheke.
Kupatula apo, Hatch adati, palibe zambiri zoti tichite kupatula kuyang'anira zomwe zikuchitika.
“Palibe chonena momwe zinthu zidzayendere, eti?” iye anatero. “Zingakhale zapamwamba. Zingakhale zochepa. Zingakhale zocheperapo. Tiyenera kungodikira kuti tiwone. Ndikusangalala kuti mndandanda wathu watha kotero sitiyenera kuda nkhawa nazo.”
Marty McKeown, yemwe nyumba yake inawonongeka kwambiri zomwe zinasiya dzenje lalikulu pansi pa chipinda chochezera, anati akukonzabe nyumbayo komanso khonde lomwe linawonongeka — ndipo kupatula ngongole ya SBA sanalandire mpumulo womwe ankayembekezera kuchokera ku mzinda kapena mabungwe ena aboma. Anati "akuda nkhawa kwambiri" ndi momwe zinthu zilili panopa, koma sakuchita mantha pamene akuyang'anira momwe bwalolo lilili.
“Tidzayang’anira mtsinje ndikuchitapo kanthu ngati pakufunika,” iye anatero. “Sindiyamba kusamuka m’nyumba mwanga. Tidzakhala ndi nthawi ngati chinachake chingachitike.”
Mbiri yatsopano ya mvula ya mu Julayi idakhazikitsidwa ku Juneau mwezi watha, ndi lipoti loyambirira losonyeza kuti mvula inali mainchesi 12.21 pa Juneau International Airport poyerekeza ndi kuchuluka kwa mvula komwe kunalipo kale kwa mainchesi 10.4 mu 2015. Panali mvula yoyezeka m'masiku onse kupatula awiri a mweziwo, kuphatikizapo mainchesi 0.77 omwe adayesedwa Lachitatu.
Kuneneratu kwa nyengo kumayambiriro kwa sabata yamawa kukufuna kuti thambo likhale loyera komanso lokwera kwambiri lifike m'ma 70.
Robert Barr, wachiwiri kwa manejala wa mzinda wa City and Borough of Juneau, anati mvula yamphamvu ku Juneau ndi yodetsa nkhawa chifukwa mtsinjewo ukakhala wokwera, pamakhala malo ochepa oti madzi adzaze mtsinjewo. Iye anati CBJ imalandira malipoti a momwe zinthu zilili tsiku ndi tsiku kuchokera ku NWSJ.
“Amatipatsa lingaliro lawo labwino kwambiri la momwe jökulhlaup ingawonekere pamlingo wosiyanasiyana wa kutulutsidwa ngati ikatulutsidwa panthawi ya lipotilo,” iye anatero. “Chifukwa chake masana aliwonse timamva zimenezo. Ndipo kwenikweni zomwe zimatiuza ndi zakuti ngati jökulhlaup itulutsidwa pakali pano, pa 20% mpaka 60% ya kuchuluka konse kwa Suicide Basin, nayi momwe jökulhlaup ingawonekere. Ngati ikatulutsidwa pa 100% ya kuchuluka kwa Suicide Basin — yomwe chaka chatha idatulutsidwa pa 96% — nayi momwe jökulhlaup ingawonekere. Ndipo pakali pano ngati ikatulutsidwa pa 100% ingakhale yoipa kuposa chaka chatha.”
Barr anati, beseni nthawi zambiri silitulutsa madzi okwanira 100%. Chaka chatha chinali kuchuluka kwambiri komwe beseni linatulutsa nthawi imodzi. Koma palibe njira yodziwira kuti madziwo adzatulutsa madzi mwachangu bwanji.
