- Isigaba Sinezivunguvungu (Imimoya ekhuthazwayo 131-155 mph, 114-135 kt, noma 210-249 km / hr): Lezi zivunguvungu ezinamandla zingabangela ukulimala okukhulu, kufaka phakathi ukulahlekelwa kwesakhiwo sophahla kanye / noma ezinye izindonga zangaphandle, iningi lezihlahla zihlanjululwe futhi ziningi amandla emigqa phansi, ukutholakala kokuhlala okungekho ngenxa yokungcola kweminyumba, nokuphuma kwamandla amasonto kuya ezinyangeni
- Isiqhingi Sesishiyagalolunye (Imimoya eqinisiwe engaphezu kuka-155 mph, engaphezu kuka-135 kt, noma ngaphezulu kuka-249 km / hr): Ukulimala okubi kuyokwenzeka. Amaphesenti aphezulu emakhaya azobhujiswa, izihlahla eziwile kanye nemigqa yamandla zizohlukanisa izindawo zokuhlala, ukuphuma kwamandla kuzodlulela amasonto kuya ezinyangeni, kanti izindawo eziningi ngeke zibe khona.
