Subseasonal Weather Outlook and Review

Over most of the central and eastern equatorial region in Week 1 (2 – 8 March), drier than usual conditions for this time of the year are predicted, along with warmer than usual temperatures.

Over much of the northeastern Maritime Continent in Week 2 (9 – 15 March), wetter than usual conditions are predicted.

Over much of Mainland Southeast Asia in Week 1 (2 – 8 March), cooler than usual temperatures are predicted to develop. These cooler conditions are likely to persist in Week 2 (9 – 15 March).

There was no discernible Madden-Julian Oscillation (MJO) signal towards the end of February, based on the RMM index. Most models predict no significant MJO activity during the forecast period (2 – 15 March), although a few models predict the development of an MJO signal in the Maritime Continent (Phase 5) during Week 1 (2 – 8 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.
