风切变
Despite being plagued by disruptive wind shear for most of its lifetime, Tropical Storm Fay steadily intensified. Veering toward the east, Fay briefly achieved Category 1 hurricane status while making landfall on Bermuda early on October 12. Wind shear eventually took its toll on Fay, causing the hurricane to weaken to a tropical storm later that day and degenerate into an open trough early on October 13.
