What does the Judge note about the weather?

The Judge notes that the weather conditions will not allow them to leave the island, even if they can get ahold of someone and let them know what's going on. Thus, they're stuck.... like it or not.

"I do not, of course, profess to be a weather prophet. But I should say that it is very unlikely that a boat could reach us - even if they knew of our plight - under twenty-four hours - and even then only if the wind drops."
