Hurikánová pozornosť na Havaji

- Tichý oceán
Novinka

Rušné chvíle začína zažívať Havaj. Začiatkom víkendu sa totiž cez ostrov prehnala tropická búrka Derby, ktorá spôsobila rozsiahlé záplavy a menšie škody na ostrovoch. Obyvatelia ešte ani poriadne neupratali a už musia byť znovu na pozore. Od východu sa totiž blížia ďalśie dve búrky. Tropické búrky Frank a Georgette. Obidve búrky by sa počas dnešného dňa mali stať hurikány prvej kategórie. Ich ďalší vývoj je zatiaľ otázny a či zasiahnú priamo Havaj je tiež veľmi nepredvídateľné. Frank by mal dosiahnuť minimálny tlak 996 hPa, Georgette 999 hPa. Obidve búrky dosahujú aktuálne rýchlosť vetra 100 km/h. Ten však bude výrazne stúpať ako budú búrky naberať na sile.
