A Thunderstorms are most likely to develop from November through April.
B The most destructive storms usually come from the northwest or north.
C When a vessel is south of an eastward-moving storm center, the approach of the low is evidenced by winds from the north to northeast.
D When a vessel is north of an eastward-moving storm center, changes in the weather are less distinctive than when sailing south of the center.
AI Explanation

The correct answer is D) When a vessel is north of an eastward-moving storm center, changes in the weather are less distinctive than when sailing south of the center. This is correct because as a storm system moves eastward, the weather changes experienced by a vessel north of the storm center are generally less pronounced compared to a vessel south of the storm center. North of the center, the wind direction and other weather elements tend to shift more gradually, while south of the center, the approach of the low-pressure system is often marked by a more abrupt shift in wind direction and other noticeable weather changes. The other options are incorrect because: A) Thunderstorms are more likely to develop on the Great Lakes from April through October; B) The most destructive storms can come from any direction, not just the northwest or north; and C) The statement about the wind direction is the opposite of what typically occurs when a vessel is south of an eastward-moving storm center.
