Subseasonal Weather Outlook and Review

Wetter conditions are predicted over much of the Maritime Continent in Week 1 (17 – 23 March). The wetter conditions are predicted to persist over the northeastern Maritime Continent in Week 2 (24 – 30 March).

Drier conditions are predicted over central and eastern Mainland Southeast Asia in Week 1 (17 – 23 March).

Cooler than usual temperature is predicted over central and eastern Mainland Southeast Asia and much of the Malay Peninsula in Week 1 (17 – 23 March). Warmer conditions are predicted over parts of the eastern equatorial region in the next fortnight (17 – 30 March).

A Madden-Julian Oscillation (MJO) signal was present over the Western Hemisphere and Africa (Phase 1) during the first week of March, based on the RMM Index. Most models predict the signal to weaken and become indiscernible around the start of the forecast period. Some models predict an MJO signal to emerge and then strengthen over the Western Pacific (Phases 6 and 7) during 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.
