Typhoon Pamela (1954)

[1] Early the next day, the Fleet Weather Center (FWC) began tracking the cyclone, which had intensified into a tropical storm, naming it Pamela.

[2] The JMA followed suit the next day, noting that it had intensified into a tropical storm[3] and deepened to have a minimum pressure of 998 hPa (29.5 inHg).

[2] At 12:00 UTC that same day, Pamela would intensify into a super typhoon according to the FWC,[2] attaining a minimum pressure of 960 hPa (28 inHg).

As a result, early on September 7, Pamela weakened into a tropical storm,[2] prior to the JMA last tracking the typhoon a few hours later.

[11][12] In Haiphong, all of the Task Force 90 ships, vessels which were involved in Operation Passage to Freedom, had to evade the typhoon until November 7.
