043 AXPQ20 PGUM 020036 TWDPQ Tropical Weather Discussion National Weather Service Tiyan GU 1036 AM ChST Mon Nov 2 2026 Tropical Weather Discussion for the Western North Pacific between the Equator and 25N from 130E to 180. The following information is based on recent satellite imagery/data, weather observations, radar, and meteorological analysis. ...SPECIAL FEATURES... TROPICAL CYCLONES... Typhoon In-fa continues to weaken as it moves into cooler waters and fights both upper-level wind shear and dry air. The latest visible imagery shows In-fa located south of Iwo To at 22.2N 141.7E, and is moving west at 6 mph. Maximum sustained winds have decreased to 85 mph, and this trend is expected to continue through tonight. In-fa may then briefly re-strengthen some over the next couple of days as it turns northwestward, before weakening further and rapidly ejecting northeastward towards the latter half of the week, heading into the north Pacific. For more information please refer to bulletins from the Joint Typhoon Warning Center under WMO header WTPN31 PGTW and from the National Weather Service under WMO header WTPQ31 PGUM. ...OTHER WEATHER SYSTEMS... MONSOON TROUGH... The monsoon trough enters Guam`s AOR near EQ140E and extends to a developing, weak circulation southeast of Chuuk/east of Satawan near 4.6N 155.1E. The trough then extends east-northeast through Kosrae, passing Majuro to its south, and exiting the AOR near 9N160. This circulation itself is very broad and resembles more of a "cusp circulation" than a true tropical circulation that would warrant monitoring more closely. As such, we don`t expect this "cusp circulation" to do much. As for the trough itself, increased surface convergence along and south of it is promoting scattered shower development, with a few thunderstorms mixed in as well. Looking ahead, we expect the trough to gradually build west through the remainder of the week, taking on an east to west alignment near 5N or 6N. Scattered showers and isolated thunderstorms will continue to develop near and south of this feature through the weekend. $$ Doll
