and made the closest approach of any hurricane to the country on record. Most of June was quiet until the end of the month, when two tropical storms developed. July remained inactive as well, as only two tropical storms formed. In August, the activity picked up somewhat; the Central Pacific had its first and only depression of the year and four tropical storms, two of which became hurricanes, forming in the Eastern Pacific. September was the most active month of the year; six tropical storms formed, four of which became hurricanes, and two of the hurricanes strengthened further to become the only major hurricanes of the year. The strongest storm of the season was Hurricane Kenneth
