Typhoon Bavi has undergone an eyewall replacement cycle, expanding its wind field into what the U.S. Joint Typhoon Warning Center is calling a "gargantuan" typhoon. According to the FOX Forecast Center, Bavi's wind field ranks in the top 3 percent of all Western Pacific typhoons over the past decade. However, the storm's maximum sustained winds have weakened following the expansion. Bavi remains on track to skirt northern Taiwan before making landfall in mainland China by Saturday.
