Extratropical cyclone, remnant low, tropical disturbance, or monsoon depressionOn 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.[1] Later that day at 12:00 UTC, the Japan Meteorological Agency (JMA) assessed that the system became a tropical depression.[2] On the next day at 12:00 UTC, the PAGASA upgraded the system to a tropical depression, assigning it the local name Tonyo.[3] The JTWC issued a Tropical Cyclone Formation Alert for Tonyo three hours later despite the presence of 20–25-knot (35–45 km/h; 25–30 mph) wind shear.[4] 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.[5] At 12:00 UTC, the JTWC upgraded Tonyo to a tropical depression, designating it as 24W.[6] The system began consolidating,[7] 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.[2][8] Etau then left the Philippine Area of Responsibility at 20:00 UTC.[8]
On November 9 at 00:00 UTC, the JTWC upgraded Etau to a tropical storm.[6] Six hours later, the JMA assessed that Etau had peaked in intensity with ten-minute sustained winds of 85 km/h (50 mph) and a minimum central pressure of 992 hPa (29.29 inHg).[2]
