From the Storm Events narratives, unedited.

The greatest storm surge that was reported was along western shores of Saipan. Based on photos taken after the event at Micro Beach, Saipan, storm surge was roughly estimated to be around 2 to 3 feet, based on subtracting the predicted astronomical tide height of 1 foot (referenced to mean sea level) from the estimated run-up line height. The Division of Coastal Resources Management at Saipan reported the following impacts: minimal structural damage to shade structures and signage along public beaches. Notable sand loss at Micro Beach, particularly along the shoreline adjacent to the lifeguard station and reef marker areas. Uprooted and broken trees, some blocking pedestrian walkways. Temporary flooding along Beach Road, especially near low-lying crosswalks and drain outlets.

A best track is the record a warning agency settles on after the storm, not what it said at the time: position, maximum sustained wind and central pressure every six hours, revised against every observation that came in later. Category is the Saffir-Simpson scale, which runs from Category 1 at 64 kt to Category 5 at 137 kt and reads wind only, so it says nothing about surge or rain. Accumulated cyclone energy adds up the square of the wind through the storm's life, so it counts strength and duration together.
