Mariners should be prepared for abrupt visibility changes down to
one nautical mile or less. Reduce speeds and be on the lookout for
exposed rocks and other vessels, including large ships in the
shipping lanes. Use radar or GPS navigation if available, and
consider remaining in harbor if such equipment is unavailable.
