Ongororo dzakapfuura dzakaratidza kuti mahwindi evakuru anoratidza nzira dzakasiyana dzekutama panguva yekuberekesa muna Kubvumbi naChivabvu kana vachifamba kubva kunzvimbo dzavo dzechando vachienda kunzvimbo dzavanoberekera. Vamwe vanobhururuka vakananga kuIceland, nepo vamwe vachityora rwendo rwavo muzvikamu zviviri nekumbomira. Gare gare, kubva mukupera kwaJuly kusvika muna August, mahwindi makuru akawanda anobhururuka akananga kunzvimbo dzawo dzechando muWest Africa. Zvakadaro, ruzivo rwakakomba nezvepwere — dzakaita semafambiro adzo uye nguva yadzinotama— hadzina kunzwisiswa kwenguva refu, kunyanya panguva yekutama kwavo kwekutanga.
