Severe Tropical Storm Fern was a damaging storm that struck Yap in the 1996 Pacific typhoon season. A tropical depression formed on December 21, when a low-level circulation center began to produce deep convection. The depression strengthened into a tropical storm the next day, and was given the name Fern by the Joint Typhoon Warning Center (JTWC). The storm slowly intensified into a Category 1 typhoon on the Saffir–Simpson hurricane wind scale, according to JTWC. Fern peaked north of Yap on December 26, with JTWC assessing winds of 150 km/h (90 mph), while the Regional Specialized Meteorological Center, Japan Meteorological Agency (JMA) assessed peak winds of 110 km/h (70 mph), just below typhoon strength. The storm soon became sheared and weakened slowly. Fern continued to weaken to a tropical depression on December 30. Both agencies stopped advisories later on the same day.
Fern made a direct hit at Yap on Christmas Day. A cargo ship was abandoned after it was damaged by high winds offshore. On the island, Fern caused $3 million (1996 USD) of damage. Roads and bridges were significantly damaged, and other public facilities were destroyed. Crops and private properties also received damage. A state of emergency was declared in Yap State two weeks later, and became a disaster area two months later.
