Subseasonal Weather Outlook and Review

Wetter conditions are predicted over most of the northeastern Maritime Continent in the next fortnight (2 – 15 February).

Drier than usual conditions for this time of the year are predicted over most of the central Maritime Continent in Week 2 (9 – 15 February).

No significant regional temperature anomalies are predicted in the next fortnight (2 – 15 February).

A Madden-Julian Oscillation (MJO) signal was present over the Western Pacific (Phase 7) towards the end of January, based on the RMM index. Most models predict the signal to weaken by the start of the forecast period and remain inactive during the forecast period, although a few models predict a short-lived MJO signal over the Western Hemisphere (Phase 1) and Indian Ocean (Phase 2) in Week 1 (2 – 8 February).

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.
