Pedzisa mutsara unotevera: Pasinei nokuva kwokutanga mumwaka, Mitag yakawedzera zvikuru kumabvazuva kwePhilippines. Musi waMarch 2, mufananidzo wesatellite wakaona ziso raiva pakati penzvimbo yakadzika kwazvo. Gare gare zuva iroro, Mitag yakapfuura nechokumaodzanyemba kwechitsuwa cheYap muFSM. Musi waMarch 3, dutu iri rakapinda munzvimbo inoyambirwa nePhilippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA); sangano racho rakabva rati "Basyang". Mvura yakadzika yakasvika yakatendeudzira dutu racho kuchamhembe kwakadziva kumadokero uye gare gare kuchamhembe. Kunyange zvazvo mhepo yaibva kumaodzanyemba kwakadziva kumadokero yaitarisirwa kuderedza kuwanda kwemvura, Mitag yakatendeukira kuchamhembe kwakadziva kumabvazuva ichibva yaenda nechokuchamhembe kwakadziva kumabvazuva, zvikaita kuti mvura inobva mumvura iyi iwedzere kuyerera. Pashure pokupedza kutenderera kwekutsiva madziro eziso, kutenderera kwakadzika kwazvo kwakapoteredza ziso, uye nhamba dzaDvorak dzakasvika pakakwirira pa7.0. Pachishandiswa izvi, JTWC yakakwidziridza Mitag kuva dutu guru musi waKurume 5, ichifungidzira mhepo dzakakwira dze 260 km / h (160 mph) apo dutu raive makiromita 610 (380 mi) kumabvazuva kweCatanduanes muPhilippines. Izvi zvakaita kuti ive dutu guru chete rakanyorwa mumwedzi iwoyo kusvikira padutu rinonzi Maysak ra
Muna 2015. Zvakare musi wa 5 Kurume, JMA yakafungidzira mhepo dzakakwira dzinosvika 175 km/h (110 mph), PAGASA yakafungidzira simba rakaenzana neJMA, uye National Meteorological Center yeChina yakafungidzira mhepo dzakakwira dzinosvika 205 km/h (125 mph ). Kwezuva rose, dutu racho rakaramba riine mhepo yakasimba, mhepo yacho isati yatanga kudzika uye mhepo inotonhorera, yakaoma yakatanga kupera simba. Mumaawa makumi maviri nemana, JTWC yakafungidzira kuti mhepo dzakaderera ne 110 km / h (70 mph) apo dutu rakashanduka kuchamhembe kwakadziva kumabvazuva, uye musi waKurume 7, Mitag yakaderera pasi pesimba redutu. Kuwedzera kwemvura inonaya inobva kumaodzanyemba kwakasanganiswa nemhepo inobva kumaodzanyemba inobva kumusoro kwakadzinga kutenderera kwemvura kunobva kumusoro, zvichikonzera kuti mhepo inobva kumaodzanyemba itendeukire kumabvazuva nokumaodzanyemba. Musi wa 8 Kurume, JTWC yakapa zano rayo rekupedzisira, uye Mitag yakaparara musi wa 9 Kurume.
