I googled as well and I found: Definition: 1. blowing strongly: describes a wind that blows strongly and makes a loud roaring sound 2. having blustery winds: subject to persistent blustery or noisy winds [Late 18th century. < obsolete wuther "to rush"] In my opinion the translation is correct :" Cime tempestose"

" Rimangano qui, per piacere " is correct. I like it and I prefer "per favore" instead of " per piacere". Of course it' s a formal expression. We could say : " Stiano qui,per favore " but it's not as polite as the first sentence ( this depends on the use of " stare" instead of "rimanere". There is a very subtle difference between the two verbs). Of course it depends also on the tone you use when pronouncing the sentence.
