Wetter conditions are expected over much of the Philippines, northern Borneo and northern Sulawesi in the next fortnight (7 – 20 March).

Wetter conditions are also expected in Week 1 (7 – 13 March) over the western Maritime Continent and may extend north to southern parts of Mainland Southeast Asia, even though the anomalies for the latter are not expected to be large. These wetter conditions are expected to ease in Week 2 (14 – 20 March).

No significant regional temperature anomalies are expected in the next fortnight (7 – 20 March).

By the end of February 2022, the Madden-Julian Oscillation (MJO) signal had decayed over the Indian Ocean (Phase 3) and has become indiscernible. Most models predict no significant MJO activity during the forecast period.

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.
