Tropical Storm Son-Tinh has set out on a path through the Philippines archipelago, where it was slated to unleash heavy rain with the threat of flooding.
Widespread damaging winds were not expected with this storm of moderate intensity.
Wednesday, the center of Son-Tinh was near the island of Leyte, tracking towards the northwest at about 20 mph. Highest sustained winds were only 40 mph, barely above the minimum threshold for a named storm.

The center of Son-Tinh was forecast to head west of the Philippines near Mindoro, south of Manila, on Thursday.
The fast forward movement of Son-Tinh would help to lower the threat of widespread, serious flooding. Still, localized rainfall was expected to potentially reach at least 12 inches, enough to spark flooding and even mudslides, in central and southern Philippines.
Beyond the Philippines, warm, open seas would await, a factor favoring a strengthening storm.
Potential for a late-week strike upon northern Vietnam and even the island of Hainan, China, was forecast.
The plum rains are known as "meiyu" in China, the "baiyu" or "tsuyu" in Japan, and the "jangma" in the Koreas. The heart of the plum rain season stretches from early June to mid-July, with a tendency to shift south to north across the affected area.
In the wake of the mid-June cloudbursts, most of Pakistan to northwestern India last week saw a return to dry, hot weather typical of the weeks leading up to the Monsoon onset. It was as if the Monsoon withdrew to its "normal" position for the latter half of June.
The 38.5 degree C (101 degrees F) reading Tuesday in Ajaccio, Corsica, may have been tops in Europe.
Monsoon Onset was June 13th, 2013, in Delhi, almost two weeks earlier than average. The June 15th onset at Karachi and Islamabad was more like three week ahead of schedule.
In Pakistan, hit-or-miss downpours missed the Sindh capital, Karachi. One did hit Pad Idan, where it left 60 mm of rain Wednesday. This was more than 20 times greater than the normal June rainfall.
It is still possible that this scenario is over wrought as to the intensity and spread of rain in Pakistan and northwestern India. However, it is the hunch of the present forecaster that some very unusual weather is going to unfold in the Subcontinent during the next week!
