Kai-Tak slammed the northern Philippines triggering flash floods and landslides and killing at least ten people, one week after deadly monsoon rains battered the country.

In Vietnam, Kai-Tak has stormed across the country's north bringing high winds and floods to several areas including the capital Hanoi.

[2] By midnight, that day, the Japan Meteorological Agency (JMA) started tracking the system as a weak Tropical Depression with winds under 30 knots.

[3] A couple of hours later, the Joint Typhoon Warning Center (JTWC) issued a Tropical cyclone formation alert (TCFA) estimating winds of up to 22 knots (41 km/h; 25 mph).

[4] As the storm was also in the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA)'s area of Responsibility, they started issuing advisories on the system, thus naming it Helen.

[8] At midnight, the JMA reported winds of 35 knots (65 km/h; 40 mph), stating that the depression had intensified into a tropical storm, thus officially naming it Kai-tak.

[10] At that time, the system had a broad, partially exposed low-level circulation center (LLCC) with deep convection persisting along the western periphery.

Though the storm entered warm watered off the Philippine coast, it failed to intensify rapidly as it was located along the southern periphery of a deep-layered subtropical ridge and was experiencing moderate vertical wind shear.

[14] By the night of August 14, Kai-tak tracked westward at 06 knots (11 km/h; 6.9 mph) and the LLCC became embedded within central dense overcast convection.

[16] On the night of August 15, the infrared satellite imagery showed that convective bands have deepened and wrapped tighter into the LLCC and an excellent equatoward outflow.

[28] On August 15, The national disaster relief authority of China issued a fourth-level alert, predicting that the storm may hit the coastal areas of the provinces of Guangdong and Fujian.

The agency asked all ships to return to port, reinforce outdoor structures, and evacuate workers from offshore oil platforms.

[30] Early on August 16, Tropical Storm Kai-Tak slammed the northern Philippines triggering flash floods and landslides and killing at least three people, one week after deadly monsoon rains battered the country, disaster relief officials said.

Another man died from electrocution in Naguilian town in nearby La Union province, said Superintendent Jovencio Badua, a regional police spokesman.

The storm blew out of the Philippines offering some relief for millions of people struggling to recover from a few weeks of monsoon rains that earlier claimed 109 lives.

“The need is massive and urgent, millions of people are suffering the miserable consequence of these floods and we must try to reach them before the rains hit again,” Anna Liendfors, the country representative of Save the Children appealed.

At the same time, weathermen warned residents living in low-lying and mountainous areas against possible landslides and flash flood due rains ranging from heavy to intense.

In Pampanga, the home province of former president Gloria Macapagal-Arroyo in Central Luzon, officials ordered the pre-emptive evacuation of residents in villages along one of the major river systems.
