Subseasonal Weather Outlook and Review

Wetter conditions are predicted over the southern Maritime Continent in the next fortnight (11 – 24 November). Wetter conditions are also predicted over parts of southeastern Mainland Southeast Asia in Week 2 (18 – 24 November).

Warmer than usual temperature is predicted over the Maritime Continent, apart from the southern region, and southern coastal parts of Mainland Southeast Asia in the next fortnight (11 – 24 November).

A Madden-Julian Oscillation (MJO) signal was present over the Western Hemisphere and Africa (Phases 8 and 1) at the beginning of November. Most models predict this MJO signal to weaken by the start of Week 1, although a few predict it to propagate across the Indian Ocean (Phases 2 and 3), reaching the Maritime Continent (Phase 4) by the end of Week 2.

The outlook is assessed for the region in general, where conditions are relative to the average conditions for the corresponding time of year. For specific updates on the national scale, the relevant ASEAN National Meteorological and Hydrological Services should be consulted.
