Jakarta -- In the coming month, low-intensity rainfall that most likely results in drought is predicted to occur in several regions of Indonesia. anticipatory steps need to be taken to minimize the potential impact of drought on, among others, water resources, forestry, agriculture, and disaster-related sectors.
La Nina has taken place for three consecutive years from 2020 to 2022, resulting in wet climate. However, the latest monitoring of sea surface temperature in the Pacific Ocean shows that currently the intensity of La Nina continues to weaken, with an index of -0.61 in early February 2023. The La Nina condition is predicted to continue to weaken and shift towards neutral conditions in February-March 2023. Neutral ENSO conditions predicted to continue until mid-2023.
Such circumstance will cause dry season in 2023 to be more adverse than the last 3 years. In a monthly detail, areas that are predicted to get potential monthly rainfall in the low category (accumulation of less than 100 mm/month) are follows:
- March: in the central part of Central Sulawesi;
