When you see a halo around the sun or moon, stand by for dirty weather. We aren’t talking here about those little ones that fuzz themselves around the heavenly body. These big chaps are sure-fire harbingers of unpleasantness. Watch the barometer. When it starts falling and the wind backs as well, that’s you for the high jump. If you’re safely anchored, batten down the hatches and let out all the cable you’ve got. Far at sea without the option, reeve up the deep reef pennant and cook a meaty stew while you still can, then invite the hands to join you in prayer.
