On September 2, 1935, Labor Day, the hurricane reached a peak intensity of 892 mb. The hurricane made landfall later that night as a Category 5 storm, crossing the Florida Keys between Key West and Miami, FL. As it made landfall, the hurricane delivered maximum sustained winds of approximately 298 km/h (185 mph). After passing the Keys, the hurricane slowly recurved northward and closely paralleled Florida’s west coast.
