Weather can change very rapidly and create unexpected emergencies for boat and PWC operators. Even meteorologists have trouble predicting rapid changes in the weather. You should always watch for changes in the weather and monitor the weather forecast.
In the 1968 BBC Radio serialization of The Hobbit, Bilbo was played by Paul Daneman. Nicol Williamson portrayed Bilbo with a light West Country accent in the 1974 performance released on Argo Records. In the 1977 Rankin/Bass animated version of The Hobbit, Bilbo was voiced by Orson Bean.
So Bilbo is our hero (because he's the main character of the book) but he is not a hero. He has no great goals in mind as he embarks on this quest â he's mainly along for the ride, because this Gandalf fellow forces him.
