AI Explanation

The correct answer is A) wind speed forecasted. The National Weather Service differentiates between small craft, gale, whole gale, and hurricane warnings based on the forecasted wind speeds. Small craft warnings are issued for winds of 20-33 knots, gale warnings for 34-47 knots, storm warnings for 48-63 knots, and hurricane warnings for winds of 64 knots or higher. The other options (cloud cover, wave heights, and rainfall) are not the primary factors used to categorize these marine weather warnings.
