 A low pressure area developed along the end of a quasi-stationary frontal trough. Initially, vertical wind shear prevented deep convection from forming on the western portion of the system. After wind shear decreased, the system became a gale center late on October 22. By early on the following day, the gale center had transitioned into a tropical storm, and it is estimated that Tropical Storm Frances developed at 0600 UTC on October 23. Frances quickly strengthened after becoming a tropical storm, and was upgraded to a hurricane by 1800 UTC on that same day. After becoming a hurricane, Frances curved northeastward, and remained well east of Bermuda. By midday on October 24, Frances peaked as an 85 mph (140 km / h) Category 1 hurricane.
