Subseasonal Weather Outlook and Review

Wetter conditions are predicted over the northeastern Maritime Continent in Week 1 (3 – 9 February).

Drier conditions are predicted over parts of the equatorial region in the next fortnight (3 – 16 February).

For temperature, cooler than normal conditions are predicted over central and eastern Mainland Southeast Asia in Week 1 (3 – 9 February). Warmer than normal temperature is predicted over the southeastern Maritime Continent in the next fortnight (3 – 16 February).

Towards the end of January, an MJO signal was present over the Maritime Continent (Phase 4), based on the RMM index. Models are split between the signal becoming inactive around the start of the forecast period and the signal continuing to propagate eastwards reaching the Western Pacific (Phases 6 and 7) during Week 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.
