Tornado Warning

Amikor otthonról eljöttem, a szülőket sikerült megnyugtatni, hogy Tennessee-ig nem szoktak felmerészkedni a hurrikánok. Ezt az álláspontot természetesen még most is tartom, azonban ha a hurrákonok nem is másznak fel idáig, a tornádók azért csak-csak megjelennek egyes hétvégéken. Idén minthat szenojuk lenne, utoljára mintegy másfél hete történt ez, amikor egy 5 mérföldre kacsázott el az egyik Nashville-től kb. 5 mérfölddel északra. Ha jól emékszem senkinek semmi baja nem történt ezúttal.

Alapvetően két dolog "tetszik" a tornádókban. Az egyik, ahogy elsötétül az égbolt - mintha korábban esteledne. De ez gondolom otthon sem ismeretlen, már csak az alábbi fényképből kiindulva sem:

Na, de amivel otthon még nem találkoztam az a vészjósló hangvételű rádiószöveg, amit az összes helyi rádió egyszerre kezd el sugározni. Ennek a szövege alább olvasható. Az egészet felolvassák a rádióba, kellemesen monoton hangon.

Mellesleg azt hiszem sikerült tudatosítanom magamban, hogy mi a külünbség a tornádó és a hurrikán között. A hurrikán rendszereint hetekig barangol, általában nevet is kap - mint tavaly az Ike. A tornádó ezzel szemben csak hirtelen kialakul, picit pörög, aztán el is tűnik. Olyan gyorsan, hogy még nevet sincs idő adni neki.
