Taifuunivaroitus Tokioon

Sain kuulla koulussa tanaan torstaina etta huomisen perjantain koulupaiva on peruttu Japania lahestyvan myrskyvaroituksen vuoksi. Tokiota lahestyy huomiseksi kova myrsky ts. taifuuni. Tulin koulun jalkeen Shibuyaan Lumene-nimiseen tavarataloon, josta loysin Wired caffeen, eli nettikahvilan, jossa opiskelin lisaa naista myrskyvaroituksista. Japaniin on annettu ns. Red Alert Shizuoka:n ja Tokioon ns. Yellow Alert, joka sekin on voimakas myrsky ja ainakin meita opiskelijoita kehoitettiin pysymaan kotona koko paiva ja opiskelemaan... Ainakin siis tuon varoituksen perusteella Tokiota ravistelee seuraavan 24 tunnin aikana TS (Tropical Storm), jossa tuleen nopeus voi olla 63 km/h. Tuplasti voivakkaamman myrskun CAT 1:n todennakoisyys Tokiossa on 10% luokkaa seuraavan 24 tunnin aikana.
