Before making landfall in Vietnam, Talas reached its peak intensity as a severe tropical storm on July 16.

The storm caused an estimated US$8.8 million in damages in Hainan, China, increased rainfall in Myanmar and Thailand, and triggered landslides and flooding in parts of Central and Northern Laos.

On July 13, the Joint Typhoon Warning Center (JTWC) began monitoring a tropical disturbance located approximately 648 km (403 mi) southeast of Hanoi, Vietnam.

[1] The Japan Meteorological Agency (JMA) classified the system as a weak tropical depression at around 06:00 UTC on July 14, as it started to move slowly towards the northwest at a speed of 19 kilometres per hour (12 mph).

[8] On July 16, Talas gradually intensified as it became better organized due to a favorable environment consisting of low to moderate northeasterly vertical wind shear and good outflow to the south.

[11] Shortly thereafter, Talas began to weaken due to land interaction and the JMA downgraded the system back to a tropical storm.

[14] Early in the following day, when the weakening storm was located over the northern portion of Laos, the JMA issued their final advisory as well.

Vietnam's National Center for Hydro-Meteorological Forecasting recorded wind gusts up to 100 km/h (62 mph), causing damage in Nghệ An, Thanh Hóa and Hà Tĩnh provinces.

[24] Seven people were injured in Quảng Bình province, where fishing boats also washed ashore on waves as high as 5 m (16 ft).

[29] On July 22, China's National Observatory issued a "blue alert"[clarification needed] to Hainan province and the Beibu Gulf.

[30] Southern portions of the province received rainfall of 3–6 in (8–15 cm) and tourists were stranded on a remote island off the coast of Guangdong.
