Subseasonal Weather Outlook and Review

For the southern ASEAN region in the next fortnight (13 – 26 November), drier conditions are predicted, except over parts of the equatorial region where wetter conditions are predicted.

For the northern ASEAN region in Week 1 (13 – 19 November), wetter conditions are predicted over much of this region. In Week 2 (20 – 26 November), drier conditions are predicted over southern Mainland Southeast Asia.

Warmer than usual temperature is predicted over most of the Maritime Continent during the next fortnight (13 – 26 November).

No Madden-Julian Oscillation (MJO) signal was present around the start of the forecast period. Most models predict an MJO signal to develop over the Western Pacific (Phase 7) in Week 1 and then propagate to the Western Hemisphere and Africa (Phases 8 and 1).

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.
