Track of TS09W

After Khanun became a tropical storm on July 16, its large area of convention associated with a tropical wave in the south began to split, and it transformed into a tropical disturbance on July 17. The JMA upgraded the system to a tropical depression on July 18 (click here for previous image).

On July 20, the tropical depression became better organized; however, due to moderate vertical wind shear, and dry air coming from the north of the system, the low level circulation center became exposed, as it developed three multiple circulation centers. Later that day, the JTWC issued a TCFA on the system, and the PAGASA upgraded it to tropical depression Ferdie. Late on the same day, the JTWC upgraded the system to a tropical depression.

On July 21, the JMA upgraded the system to a tropical storm and named it Vicente, so did the JTWC later on the same day, as the system’s convection finally wrapped around the storm’s center of circulation.

The depression caused widespread rains and gusty winds in Luzon and Visayas region due to the enhancement of southwest monsoon. Excesses of aproximately 40 mm/hr rainfall were recorded under the 400 diameter of the depression. On July 20, classes were suspended from pre-school to high school level due to heavy rain and severe flooding. Some were stranded in their offices and residents were advised to seek in higher ground. Gale warnings were also released. About 2 people have been reported dead and 6 others are officially missing.
