Passage: Substantial intensification ensued on September 11, as Mangkhut traversed the Philippine Sea. A second bout of rapid intensification took place as the storm consolidated significantly; a well-defined 39 km (24 mi) eye became established during this time. The JTWC analyzed Mangkhut to have reached Category 5-equivalent intensity by 12:00 UTC, an intensity it would maintain for nearly four days. The JMA assessed that the typhoon's central pressure bottomed out at 18:00 UTC, with 10-minute sustained winds of 205 km/h (125 mph) and a central minimum pressure of 905 hPa (mbar; 26.73 inHg). The JTWC noted additional strengthening on September 12, and assessed Mangkhut to have reached its peak intensity at 18:00 UTC, with one-minute sustained winds of 285 km/h (180 mph). The typhoon made landfall in Baggao, Cagayan at 2:00 a.m. PST on September 15 (18:00 UTC on September 14), as a Category 5-equivalent super typhoon, with 10-minute sustained winds of 205 km/h (125 mph) and 1-minute sustained winds of 270 km/h (165 mph). This made Mangkhut the strongest storm to strike the island of Luzon since Typhoon Megi in 2010, and the strongest nationwide since Typhoon Haiyan in 2013.Traversing the mountains of Luzon weakened Mangkhut before it emerged over the South China Sea on September 15. The typhoon subsequently made landfall again on the Taishan coast of Jiangmen, Guangdong, China, at 5 p.m. Beijing Time (09:00 UTC) on September 16, with 2-minute sustained winds of 45 m/s (160 km/h).Following landfall, Mangkhut quickly weakened while moving westward. Late on September 17, Mangkhut dissipated over Guangxi, China.

Question: What was the minimum pressure of the typhoon in hPa?
