Subseasonal Weather Outlook (16 Apr – 30 Apr 2019)

Issued 12 Apr 2019
Valid for weeks 3 and 4: 16 Apr – 30 Apr

Figure 1: Rainfall Outlook

Figure 2: Temperature Outlook

In the third week of April 2019, drier-than-usual conditions are expected to develop over parts of the Mekong sub-region, as well as over Malaysia and the Philippines. In the last week of the month, wetter-than-usual conditions are expected to develop over parts of Indonesia, with a possible development of Madden-Julian Oscillation (MJO) over the Indian Ocean. Most models predict the MJO to propagate slowly towards the east into the western Maritime Continent before weakening.

Warm conditions are expected to persist over the Mekong sub-region, as well as the northern part of Peninsular Malaysia.

The outlook is assessed for the region in general. For specific updates on the national scale, the relevant ASEAN National Meteorological and Hydrological Services should be consulted.
