A few hours ago, the eye of Super Typhoon #Sinlaku passed over the island of Saipan (CNMI). A @wunderground PWS station on the island reported pressure data from the eye of the storm, with a minimum pressure of 917 mbar (bias-corrected) being reported at 1420Z!

@wunderground While the minimum pressure reported was 927.87 mbar, comparison of the PWS's data with that of older METARs from the Saipan Intl Airport (which stopped reporting pressure after a report of 941.8 mbar at 1054Z) indicated a high bias of 10 to 12 mbar. Adjusting for this yields an

@wunderground estimate of 917 mbar for the minimum reported pressure. The PWS did not encounter the centre of the storm, suggesting that the minimum pressure at the time was ~910 mbar (corresponding to ~130 kt winds), substantially deeper than the JTWC's estimate of 930 and JMA's 920!
