Omnye Izaqhwithi ezinkulu zigcina izigidi zabantu zisengxakini E-United States, kukho indlela eyingozi esuka eMzantsi Texas ukuya kwiGreat Lakes nakumantla-mpuma. Iinkanyamba, isichotho esikhulu, umoya onamandla kakhulu, kunye nezikhukula ezikhawulezileyo zidibene nenye yezona ziganeko zibalulekileyo zemozulu kwixesha lonyaka.
Izibikezelo ezivela kwiNational Weather Service (NWS), kwiStorm Prediction Center (SPC), nakwiindawo ezahlukeneyo zeendaba ezikhethekileyo zikhomba oku. iintsuku ezininzi ezilandelelanayo zokungazinzingeentsuku ezibalulekileyo eMidwest naseGreat Plains. Izixeko ezifana neChicago, Milwaukee, Des Moines, Oklahoma City, Dallas, Detroit, kwaneendawo ezikufutshane neNew York zichaphazeleka zizilumkiso zobunzima obahlukeneyo.
Indawo enobungozi edlula iikhilomitha ezingama-2.000
Ngokolwazi oluqokelelwe kwi I-NOAA, i-NWS kunye neendaba ezifana neReuters, i-CNN okanye i-ABC NewsUmmandla omkhulu we-United States esembindini nasempuma uphantsi kwesilumkiso sesiphango esinzima. I-SPC ide yabeka iindawo zesiphango "njengomngcipheko ophuculweyo" (inqanaba lesi-3 kwelesi-5), ngakumbi kwiindawo ezisempuma ye-Iowa, emazantsi eWisconsin, nakumantla e-Illinois, apho indibaniselwano yomoya ofudumeleyo, omanzi kunye notshintsho lomoya olunamandla oluphezulu lukhuthaza ukwakheka kwee-supercells.
Kuloo khorido, eqala kwiBig Bend yaseTexas nakwinxalenye esemantla yelizwe ukuya kwiNtaba ephezulu yaseMississippi, kulindeleke oku kulandelayo. iziphepho ezikwaziyo ukuvelisa isichotho esifikelela kwiisentimitha ezi-7 ububanziIingqimba zomoya ezidlula i-100 km/h kunye neenkanyamba ezinamandla (EF2 okanye ngaphezulu) zinokwenzeka. Intshukumo ephezulu idla ngokwenzeka phakathi kwemini kunye nokuhlwa kwasekuseni, xa umoya ufikelela ekungazinzini okukhulu.
Ngasezantsi, eMathafeni, ubukho be- umgca owomileyo phezu kwe-Oklahoma kunye neNtshona yeTexas Isebenza njengesibangeli esongezelelweyo sokwenziwa kweeseli eziqinileyo kakhulu. I-SPC ibonise ngokuphindaphindiweyo amathuba aphezulu eziganeko zemozulu embi ukusuka kumantla eTexas nase-Oklahoma ukuya eKansas nase-Ohio Valley, inika ingqalelo ngakumbi kwiindawo ezifana ne-Oklahoma City, iTulsa, iWichita, kunye neJoplin.
Okwangoku, izilumkiso zifikelela kumantla-mpuma, apho Iziphepho ziyaqhubeka nokuchaphazela iindawo ezikufutshane neGreat LakesINew England kunye neendawo ezithile zaseNew York nasePennsylvania. Nangona ubushushu bungasoloko buqhelekile kwezi ndawo, isichotho esikhulu, umoya onamandla, kunye neziqephu zemvula enkulu kwixesha elifutshane azinakucinywa.
Iinkanyamba, isichotho esikhulu kunye nomonakalo omkhulu eMidwest
Ukuqala kwesi siqendu kushiye umkhondo Kuqinisekiswe iinkanyamba eKansas, eIowa, eMinnesota naseWisconsin.ngomonakalo omkhulu kwiindawo ezininzi zasemaphandleni nakwiidolophu ezincinci. KwiSithili saseMiami-Dade, eKansas, inkanyamba eyayibizwa ngokuba yi-EF2 yatshabalalisa iishelufu, amakhaya, kunye namashishini, yonakalisa izakhiwo ezimalunga ne-100, yaza yashiya abantu abaninzi benomonzakalo omncinci.
Iidolophu ezifana neHillsdale kunye ne-Ottawa, eKansas, zirekhodiwe uphahla luqhekekile, iintsika nemithi ziwile, neendlela zivaliwe Abasemagunyeni bavula iindawo zokuhlala zexeshana, bahlola indlu ngendlu, baza bacela inkxaso kwimibutho efana neRed Cross ukunceda iintsapho ezifuduselwe kwenye indawo.
Kumantla eMinnesota, i-NWS iqinisekisile ukuba inkanyamba idlule kufutshane neTruman, ngelixa kumazantsi elizwe, kubikwe ukuba kukho izivuthuvuthu. amatye esichotho anobukhulu beebhola zegalufa nto leyo echaphazele izityalo, izithuthi, kunye nophahla lwezakhiwo. EWisconsin, ukongeza kumonakalo kwiziseko zasemaphandleni, bekukho ukunqamka kombane ixesha elide kunye nokuphazamiseka konxibelelwano, nto leyo eyanyanzela amaqela ongxamiseko ukuba aphinde kabini imizamo yawo.
I-CNN ikwabhale phantsi Iziphepho ezitshabalalisayo ziyaqhubeka kwiindawo zaseKansas naseWisconsinngeengxelo ezingaphezu kweshumi elinesibini zeenkanyamba kwiiyure ezingama-24 kuphela. Kwiindawo ezahlukeneyo, isichotho sifikelele kubukhulu obufana nobebhola yebhola, nto leyo ebangele umonakalo omkhulu eluphahleni, kwiifestile, kwiindawo zolimo nakwiintambo zombane.
Okwangoku, iqela elitsha elinxulumene nenkqubo efanayo lenziwe ikhephu kunye neemeko zasebusika kwiintaba zeColorado Rocky, kunye neengozi zendlela kwiindawo eziphakamileyo zeentaba, nto leyo ebonisa umahluko omkhulu kwimozulu onokwenziwa yinkqubo enye yoxinzelelo oluphantsi eMelika.
Izikhukula zembali kunye noxinzelelo kumadama eMichigan naseWisconsin
Elinye icala lale meko kukuba umngcipheko okhulayo wezikhukula ezijikeleze iiGreat LakesIngakumbi eMichigan naseWisconsin, apho ukuqala kwentwasahlobo bekusele kunetha kakhulu. Ukunyibilika kwekhephu eliqokeleleneyo kunye nezihlandlo ezintsha zemvula enkulu kuye kwanyusa kakhulu amanqanaba emilambo kunye namachibi.
EMichigan, uMlambo iManistee, kufutshane neSherman, idlule irekhodi layo lembali lesikhukulaUmgangatho womlambo unyuke ngaphezu kweemitha ezi-5,5, udlula irekhodi langaphambili elalibekwe ngo-2014. Olu khukula lonakalise iindlela kunye neebhulorho, lwagubungela izindlu kwiindawo ezisezantsi, lwaza lwanyanzela abantu abatsha ukuba baphume kwiindawo ezithintelweyo.
Imeko ibuthathaka ngakumbi kwezinye izakhiwo ze-hydraulic, ezifana ne- Idama iBig Falls eWisconsin okanye iBellaire kunye neCheboygan Dams eMichiganapho kufunyenwe khona ukuvuza okanye amanqanaba amanzi akufutshane kakhulu nomda wokhuseleko. Ngenxa yokuba kungenzeka ukuba isakhiwo singaphumeleli, abasemagunyeni baye bayalela ukuba kufuduke abantu kwiidolophu ezisezantsi komlambo kwaye bafake iingxowa zesanti kunye nezinto zokuqinisa ukuthintela ukuhamba kwamanzi.
Abacimi-mlilo, amaqela okhuseleko loluntu kunye neenkonzo zongxamiseko kuye kwafuneka abahlali bokuhlangula abavaleleke kwizindlu ezikhukuliswe ngamanzinjengakwidolophu yaseSuamico, eWisconsin. I-NWS ikhuphe izilumkiso zezikhukula ezikhawulezileyo kwiingingqi ezininzi, ilumkisa ukuba nayiphi na imvula engaphezulu ingenza imeko ibe mandundu ngakumbi.
Ukujonga imilambo kugcinwa kungaguquki, amanqanaba ezilumkiso kwiindawo eziphantse zibe lishumi elinesibini eMichigan naseWisconsinKwezinye iindawo, ezifana noMlambo iMuskegon, kulindeleke ukuba kubekho izikhukula ezinkulu, nto leyo enokufuna ukuba abantu bafuduke kwiindawo zokuhlala ezikufutshane nomlambo.
Abantu abangaphezu kwezigidi ezili-130 baphantsi kweliso elibukhali lesiphepho
Iiarhente ezahlukeneyo zemozulu ziyavumelana ukuba Amashumi ezigidi zabantu achanabeke kwimozulu embi kwesi siqendu. Amanye amanani abeka inani labemi abangaphezu kwezigidi ezili-130 phantsi kweliso okanye belumkisiwe ngaxa lithile ngeli xesha, ukusuka kumathafa asembindini ukuya kumntla-mpuma welizwe.
I-NWS kunye ne-SPC zigxininise ukuba, ngaphaya kokuqhambuka kweenkanyamba ezithile, Imimoya enamandla kunye nesichotho zizinto ezisongelayo ezixhaphakileyo. Ngaphezu koko, izivuthuvuthu eziphindaphindayo kwiindawo ezifanayo zonyusa umngcipheko wokuna kwemvula enkulu, ngoko ke, izikhukula ezikhawulezileyo.
Iindaba ze-ABC kunye neFox Weather zigxininisa ukuba indibaniselwano yomoya ofudumeleyo nofumileyo Ivela kwiGulf of Mexico, apho umoya obandayo uvela emantla kunye nomsinga we-polar jet onamaza, oku kudala indawo efanelekileyo yokuzalela kwezi ziganeko zasentwasahlobo. Ukungqubana phakathi kwezi moya zahlukeneyo kuchaza ukwakheka kwee-supercells kunye notshintsho olukhawulezileyo lobushushu kunye notshintsho olukhawulezileyo kwiimeko zesibhakabhaka.
I-Federal Emergency Management Agency (FEMA) ibike ukuba ukubonelelwa kweendawo zokuhlala zexeshana ezininzi kumazwe achaphazeleke kakhulu, kunye nokuthunyelwa kwamaqela okubuyisela iinkonzo ezisisiseko. Ulungelelwaniso phakathi kweengcali zemozulu kunye namagunya okhuseleko loluntu luthathwa njengento ebalulekileyo ekunciphiseni impembelelo kunye nokulungiselela imizamo yokuphendula kunye nokubuyisela kwimeko yesiqhelo.
Ukongeza kwizibhengezo ezisemthethweni kumabonakude nakwirediyo, ukusetyenziswa usetyenziso lweselula kunye neenkqubo zokulumkisa kwangethuba ukufumana izaziso zeenkanyamba, izivuthuvuthu ezinkulu, okanye izikhukula. Kwiindawo ezininzi zasemaphandleni, apho ii-siren zisengumthombo oqhelekileyo, kuyacetyiswa ukuba uzidibanise neetshaneli zedijithali ukuqinisekisa ukuba imiyalezo ifikelela kubantu abaninzi kangangoko kunokwenzeka.
Impembelelo kubomi bemihla ngemihla: izikolo ezivaliweyo, ukucima kombane, kunye neendlela ezikhukuliswe ngamanzi
Imiphumo yezi nkqwithela kubomi bemihla ngemihla ibonakala kakhulu iindawo ezinkulu zedolophu kunye neendawo zasemaphandleniKwizithili ezininzi zezikolo kulo lonke elaseMidwest nasePlains, iiklasi ziye zamiswa okanye zafuduselwa kwifomathi ekude ukuze kuncitshiswe ukuhamba ngexesha leeyure ezixakekileyo.
Ukucinywa kombane kube yingxaki ephindaphindayo, ingakumbi emva kweziganeko zakutshanje. iinkqwithela ezinemimoya enamandla kakhulu kunye nesichotho eziyonakalisa imigca yombane kunye neetransformer. Amawaka ezindlu kunye namashishini ashiywe engenambane ngamaxesha ahlukeneyo, nto leyo eyenza kube nzima ukusebenza kweenkonzo ezibalulekileyo kunye nonxibelelwano xa kukho imeko engxamisekileyo.
Abasemagunyeni babongoza ukuba kuqatshelwe kakhulu uthungelwano lweendlela. Iindlela ezikhukuliswe ngamanzi, iibhulorho ezonakeleyo, kunye neendlela ezivalwe yimithi ewileyo Banyanzela iindlela ezijikayo zize zivalwe okwethutyana. Eyona ngcebiso iphindaphindwayo kukuphepha ukunqumla iindawo ezikhukuliswe ngamanzi ngemoto, njengoko amandla amanzi anokuthi akhukulise izithuthi nokuba umgangatho awubonakali uphezulu kakhulu.
Uthutho lweenqwelo-moya nalo lufumana impembelelo, kunye ukulibaziseka kunye nokurhoxiswa kweenqwelo-moya eziphambili kulo lonke ilizwe Xa iziphango zidlula kufutshane neendawo ezinkulu zasezidolophini, abaqhubi bacebisa ukuba bajonge imeko yendiza ngaphambi kokuba baye kwiindawo zokugcina izithuthi kwaye balungiselele utshintsho lwemizuzu yokugqibela kwiindlela zokuhamba kunye neeshedyuli.
Kwicandelo lezolimo, Izichotho kunye nomoya ovuthuzayo zonakalise izityalo kunye nezakhiwo ezinxulumene nazo kwimisebenzi yezolimo, njengeeshedi zoomatshini okanye ii-silos. Nangona kusesekutsha kakhulu ukwenza uvavanyo olupheleleyo lwelahleko kwezoqoqosho, iingxelo zokuqala zibonisa impembelelo ebalulekileyo kwezinye iindawo zaseKansas, eMinnesota, eWisconsin, nakwamanye amazwe angabamelwane.
Yintoni ecetyiswa ngabasemagunyeni xa kukho ingozi yeenkanyamba kunye nemvula enkulu?
I-National Weather Service kunye ne-NOAA zigxininisa inani le izikhokelo ezisisiseko zokuzikhusela Ezi zinokwenza umahluko omkhulu ngexesha lesiganeko semozulu embi. Ziquka ukwazi indawo ekhuselekileyo yokuhlala ekhaya, emsebenzini, okanye esikolweni; ukulungiselela isixhobo esincinci songxamiseko esinethotshi, amanzi, unomathotholo kunye neetshaja; nokuqonda umahluko phakathi kwenkanyamba okanye umlindo wesiphango esinzima kunye nesilumkiso sesiphango esinzima.
Xa kukho isilumkiso senkanyamba, abasemagunyeni bagxininisa ukuba funa indawo yokukhosela ngokukhawuleza kwindawo engaphakathi nesezantsi yesakhiwokude neefestile, kungcono ukuba ube kumgangatho ongaphantsi, kwigumbi lokuhlambela elingaphakathi, okanye epasejini engenaglasi. Ukuba akukho zakhiwo ziqinileyo ezikhoyo, kucetyiswa ukuba ulale phantsi emseleni okanye kwindawo exibilikileyo emhlabeni kwaye ukhusele intloko yakho, uphephe ukuzimela phantsi kweebhulorho zeendlela ezinkulu okanye kwiimoto ezivezwe ngaphandle.
Ngokuphathelele izikhukula, umyalezo ucacile: Musa ukuzama ukunqumla izitalato okanye iindlela ezigcwele amanziAkukho ngeenyawo okanye ngemoto. Iisentimitha ezimbalwa zamanzi ahambayo zanele ukumenza umntu angazinzi, kwaye umsinga omkhulu kancinci unokukhukulisa imoto. Isiqubulo esithi "jika, ungangeni" siphindaphindwa kwiiphulo ezininzi zokwazisa abantu ukuze kukhunjuzwe abantu ngengozi yokungawaxabisi amanzi aqokelelweyo.
Iinkonzo zongxamiseko ze-FEMA kunye nekarhulumente zicebisa ukuba iintsapho phuhlisa isicwangciso esilula sokwenza izinto Oku kufuneka kuquke iindawo zokudibana, ulwazi loqhagamshelwano, kunye neendlela ezahlukeneyo zokufuduka. Kukwacetyiswa ukuba kuhlolwe imigaqo-nkqubo yeinshorensi yasekhaya neyezithuthi ukuze kuqondwe ukugutyungelwa kwayo komonakalo obangelwe ziziphango, izikhukula, okanye isichotho.
Kwinqanaba lesikhungo, amazwe achaphazeleke kakhulu asebenze iinkqubo zongxamiseko kunye nezibhengezo zentlekele eziququzelela ukufika kwezixhobo zoncedo kunye noncedo lukarhulumente. Oku kuquka ukuthumela abasebenzi abongezelelweyo, oomatshini abanzima ukuze bacoce iindlela, iijenereyitha zamaziko abalulekileyo, kunye nenkxaso yezothutho yokusasazwa kwezixhobo ezisisiseko kwiindawo ezikude.
Utshintsho olulindelekileyo: iintsuku ezininzi zemozulu embi ngaphambi kwekhefu
Iimodeli zokuqikelela ezijongwe ziinkonzo zemozulu zibonisa ukuba Imozulu embi iya kuqhubeka kangangeentsuku ezininzikunye notshintsho oluncinci kwindawo enobungozi obukhulu njengoko inkqubo yangaphambili iqhubeka. Enye yeentsuku ezibalulekileyo phakathi evekini, apho kulindeleke umsebenzi onzima kakhulu ukusuka eMntla Texas ukuya eOhio Valley.
Kule candelo, iinkqwithela ezinemibane, imimoya enamandla, isichotho kunye neenkanyamba ezinokubakho Imvula iza kugxila kakhulu kumathafa asemazantsi, kwiindawo ezikwiMidwest, nakwiindawo ezikufutshane neGreat Lakes. Kamva, le nkqubo iza kuqhekeka kwaye ibe buthathaka, kodwa isenokuvelisa iimvula ezisasazekileyo kunye neendudumo kumantla-mpuma e-United States nakwiindawo ezikwiMid-Atlantic.
Izibikezelo zibonisa imeko ezinzileyo ngakumbi ekupheleni kweveki, nangona Iziphepho ezishiyekileyo azinakuthintelwa eNew England nakwiindawo ezikufutshane. Kwangaxeshanye, umphezulu obandayo uza kuhamba unqumla uMntla-ntshona wePacific, uzise ikhephu kwiindawo zeentaba kunye nokwehla okukhulu kwamaqondo obushushu kwiindawo ezisemantla.
Olu hlobo lwesiqendu luwela ngaphakathi iphethini eqhelekileyo yentwasahlobo yaseMelikaOku kwenzeka xa umoya obandayo ovela eKhanada udibana nomoya ofudumeleyo nofumileyo ovela kwiGulf of Mexico, nto leyo ebangela ukuba umsinga wejet uthathe indlela egosogoso kakhulu. Isiphumo siluthotho lweentsuku ezinomahluko obushushu obunamandla, utshintsho olukhawulezileyo lwemozulu, kunye nezivuthuvuthu ezinkulu eziphindaphindayo.
Nangona esi siganeko senzeka kude neSpain nakwezinye iindawo zaseYurophu, iingcali zithi Iziganeko zemozulu ezinkulu kakhulu zinefuthe ekujikelezeni komoya kwihlabathi liphelaUkujikeleza kwe-polar jet stream okuvumela imozulu embi eMntla Melika ngamanye amaxesha kunokunxulunyaniswa namaxesha okuvaleka okanye utshintsho lwepateni kwiAtlantiki nakwilizwekazi laseYurophu, kunye nemiphumo kumaqondo obushushu, imvula kunye nobude bamaza obushushu okanye ukubanda.
Njengoko kukho iintsuku ezininzi zokoyikiswa okwandayo, inani elikhulu labantu abaphantsi kweliso, kwaye sele kukho umonakalo omkhulu kwiziseko zophuhliso, izindlu, kunye neenkonzo ezisisiseko, Izivuthuvuthu ezinkulu ezigqugqisa kumbindi nakwimpuma ye-United States ziye zaba zezinye zeziganeko zemozulu ezibalulekileyo zeli xesha lonyaka.Uphuhliso lweentsuku ezizayo luya kuba lubaluleke kakhulu ekumiseleni umlinganiselo wokugqibela wempembelelo kunye nobukhulu bemisebenzi yokwakha ngokutsha eya kujongana noluntu oluchaphazelekayo.
