In the succeeding days, Haikui reached severe tropical storm strength and eventually became a typhoon, before making landfall near Taitung City, Taiwan on September 3.

While Typhoon Saola was exhibiting a counterclockwise loop east of the Philippines, a new low-pressure area developed into a tropical depression on August 27 near the Northern Mariana Islands.

The depression, which was slowly drifting westward, was subsequently upgraded by the JMA into a tropical storm on August 28, naming it Haikui.

Haikui then moved west-northwest and eventually entered the Philippine area of responsibility at around 21:00 PHT (13:00 UTC) and was promptly assigned the domestic name Hanna.

Haikui then continued westwards over the Philippine Sea with little change in intensity, but later intensified into a Category 2-equivalent typhoon a day later.

[2] On September 5, Typhoon Haikui made its third and final landfall along the coast of Dongshan County, Fujian as a weakening tropical storm.

[4] Classes were suspended in some regions including Metro Manila on September 1 in the wake of the three storms that bring heavy rains and gusty winds throughout the country.

Although no deaths were reported, parts of the country experience floods, downed trees, and continued rainfall after Haikui made a second landfall.

At 11:05 pm, the highest warning level, Black rainstorm signal, was issued due to continued worsening situations.
