Subseasonal Weather Outlook and Review

Wetter conditions are predicted over much of the Maritime Continent in the next fortnight (17 February – 2 March).

No significant regional temperature anomalies are predicted in the next fortnight (17 February – 2 March).

A Madden-Julian Oscillation (MJO) signal was present over the Western Pacific (Phases 6 and 7) in the second week of February. Models predict this MJO signal to propagate eastwards, reaching the Western Hemisphere and Africa (Phase 8) by the start of the forecast period. Most models predict the MJO to remain in Phase 8 throughout Week 1 (17 – 23 February), with some models indicating a weakening of the signal in Week 2 (24 February – 2 March).

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.
