Central pressure 998hPa
most Large wind speed: 20 m/s (near the center)
Maximum instantaneous wind speed: 30 m/s
===================

Typhoon No. 13 is moving westward near the Midway Islands as of 6 p.m. It will continue to move westward as it continues to develop, reaching the sea near Minamitorishima around 3pm on the 1st, and is expected to become a "very strong" force with a central pressure of 925 hPa, a maximum wind speed of 50 m/s near the center, and a maximum instantaneous wind speed of 70 m/s.
