PRAYA - The Meteorology, Climatology and Geophysics Agency (BMKG) appealed to the public in the West Nusa Tenggara Province to be aware of the potential for an increase in rainfall in early December 2023. "Be aware of the increase in rainfall in early December 2023," said BMKG forecaster Climatology Station of South Nusa Tenggara Sucit Agustiarini in a written statement in Mataram, quoted by ANTARA on Friday, December 1. On the basis of December 2023 (1 10 December 2023) it is estimated that rain is likely to occur throughout the NTB region. Rainfall with high intensity of more than 150 millimeters/das is likely to occur in parts of the northern Central Lombok and West Lombok region with a chance of 30 - 50 percent. In part of the western Sumbawa region and northern Bima or around Tambora there is an opportunity of rainfall with an intensity of 100-150 millimeters/das. "Rains with an intensity of 50-100 millimeter/das are likely to occur throughout the island of Lombok, parts of western Bima, West Sumbawa, and parts of West Sumbawa with an opportunity of more than 50 percent," he said. The positive IOD condition is predicted to last until the end of 2023, while moderate El Nino is predicted to continue until April 2024. Air mass flow in the eastern region of Indonesia is still dominated by the eastern wind, especially the southern part of Indonesia around NTB. "Air mass flow is predicted to be still dominated by east wind at a weakened speed," he said.

The latest analysis shows that MJO will be active in phases 4 and 5 (Indonesian territory) at the beginning until the end of the basis of December 2023. MJO is related to convection/potential activities of rain clouds in Indonesian territory. "During the transition to the rainy season 2023/2024, people need to be aware of potential hydrometeorological disasters such as heavy rains, strong winds that can occur suddenly and locally. In some areas that have high chance of rain, it is necessary to be aware of the occurrence of floods and landslides," he said.
