Meteorological history
On November 6 at 06:00 UTC, the Joint Typhoon Warning Center (JTWC) began monitoring an area of convection northeast of Palau, noting a broad low-level circulation and favorable conditions surrounding the system. Later that day at 12:00 UTC, the Japan Meteorological Agency (JMA) assessed that the system became a tropical depression. On the next day at 12:00 UTC, the PAGASA upgraded the system to a tropical depression, assigning it the local name Tonyo. The JTWC issued a Tropical Cyclone Formation Alert for Tonyo three hours later despite the presence of 20-25 kn wind shear. Tonyo made landfall on Ticao Island at 13:00 UTC, Torrijos, Marinduque at 20:30 UTC, and at San Juan, Batangas at 00:00 UTC on November 8. At 12:00 UTC, the JTWC upgraded Tonyo to a tropical depression, designating it as 24W. The system began consolidating, and at 18:00 UTC, both the JMA and the PAGASA upgraded it to a tropical storm, with the JMA assigning it the international name Etau. Etau then left the Philippine Area of Responsibility at 20:00 UTC.

On November 9 at 00:00 UTC, the JTWC upgraded Etau to a tropical storm. Six hours later, the JMA assessed that Etau had peaked in intensity with ten-minute sustained winds of 45 kn and a minimum central pressure of 992 hPa.
