Question 1238Navigation General

The correct answer is A) Thundershowers. Based on the weather map provided in illustration D013NG, the vessel's position at point I is located in an area with a low-pressure system, which typically brings thundershowers or unsettled weather conditions. The presence of the low-pressure system and its associated frontal activity suggests that the vessel will experience thundershowers as it travels towards Seattle from Japan. The other answer choices are incorrect because: B) Overcast skies with rising temperature and D) Clear skies with warm temperatures do not align with the weather pattern indicated by the low-pressure system on the map. C) Steady precipitation is also not the most accurate description, as thundershowers involve intermittent precipitation rather than steady rain.
