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.
Luckily, two of the dwarves (Fili and Kili) find a cave in a side of the mountain. They bring in the ponies and make camp for the night. In the middle of the night, Bilbo wakes with a start, just in time to see the ponies get dragged into an enormous crack that has opened in the cave wall.
