Emerging into the South China Sea a few days later, the system strengthened into the second deadliest and twenty-third named storm of the 2017 Pacific typhoon season.

Strong winds, heavy rainfall and severe flooding in Central Vietnam caused by the typhoon killed 142 people and total damage reached over 22 trillion VND (US$1 billion).

On October 31, the Japan Meteorological Agency (JMA) began monitoring a weak tropical depression located approximately 349 km (217 mi) to the west of Cebu.

[5] By November 1, the JTWC had classified Ramil as a tropical depression, giving the international designation of 28W,[6] after convection around its low-level circulation center (LLCC) began to consolidate.

[8] After the system entered a favorable environment for intensification, including continuous convective organization, the JTWC followed suit on upgrading it to a tropical storm.

[21] Three hours later, the JTWC followed suit and classified it as a Category 1-equivalent typhoon,[22] after animated satellite imagery depicted a "strengthening" system and a well-defined circular eye like feature.

[25] Six hours later, microwave images showed the eye becoming well-defined and an improved storm structure with a large centralized convective mass occluding to its center.

[27] The JTWC issued their final advisory on the typhoon on 03:00 UTC on November 4, as it made landfall in Vạn Ninh District, Khánh Hòa Province, Vietnam.

[32] On October 31, the PAGASA had raised a Tropical Cyclone Warning Signal #1, the lowest of five, to a few provinces, mostly over Western Visayas (Region VI) and the island of Palawan.
