At 18:00 UTC the same day, the JMA declared it as a tropical depression. Five and half hours later, the JTWC issued a TCFA as its circulation and convection had significantly improved. At 09:00 UTC the next day, the JTWC upgraded the disturbance to a tropical depression, designating it as 19W. The JTWC later upgraded it to a tropical storm as it was noted that an eye-like feature was forming. The JMA later did the same at 00:00 UTC on September 7, naming it Chanthu.

Several hours later, the typhoon reached Category 4-equivalent status, and by the next day at 09:00 UTC, it reached Category 5-equivalent intensity, developing a -wide eye which was surrounded by very compact, intense convection. After reaching its initial peak, Chanthu was downgraded to a Category 4-equivalent super typhoon as its pinhole-shaped eye started to fade. However, by September 10, Chanthu began to re-intensify as its eye began to clear up. Chanthu further intensified into a Category 5-equivalent super typhoon once again at 09:00 UTC that day.
