Later, the system attained its peak winds of 285 km/h (177 mph) and an estimated pressure of 878 mbar (878 hPa; 25.9 inHg). According to the JMA, however, Keith's peak ten-minute sustained winds were 205 km/h (127 mph) and the pressure was 910 mbar (910 hPa; 27 inHg).

Despite the severity of damage, there were no reports of loss of life and only one injury in relation to the typhoon. Throughout the Northern Mariana Islands, monetary losses from Keith amounted to $ 15 million (1997 USD).
