Subseasonal Weather Outlook (10 – 23 August 2020)
Issued 8 August 2020
During the fortnight (10 Aug – 23 Aug), wetter conditions are expected over southern Southeast Asia particularly over the near-equatorial region as highlighted in the rainfall map.
Warmer conditions are expected during the fortnight over the southern and western parts of Southeast Asia.
A Madden-Julian Oscillation (MJO) signal developed over the Indian Ocean in the past fortnight, propagated eastwards and is now in the western Maritime Continent. Most models predict the MJO to continue propagating eastwards but may weaken in the first week.
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.
