Being Alert of Potential Heavy Rain in Papua – Climatologically, areas in the Seasonal Zone in Papua will experience an increase in the frequency and intensity of rain events from September to November each year as a sign of the beginning of the rainy season.

This condition also generally begins with the transition from the dry season to the rainy season, with weather characteristics generally occurring with short duration of heavy rain accompanied by thunderstorms and strong winds.

            “The rainy season is marked by increasing the incidence of rain gradually and continually until it reaches the peak of the rainy season which generally occurs at the beginning of the following year, namely January, February and March,” explained an Acting BMKG Region V Jayapura Yustus Rumakiek, S.Si., Monday (10/10). ) yesterday.

It is said, as for the areas that are in the Seasonal Zone in Papua including: Jayapura Regency, parts of southern Keerom Regency, Jayawijaya, Lanny Jaya, Yahukimo, Bintang Mountains and its surroundings and Merauke Regency.

Areas not mentioned above generally have a one-season type, namely the rainy season that falls evenly throughout the year with varying peaks of rain. Especially for the city of Jayapura, it has type 1 season with the peak of rain occurring at the beginning of the year (January-February).

The results of the latest atmospheric dynamics analysis for the Papua region on October 10, 2022 show that the Global La Nina climate phenomenon is still active, which increases the availability of water vapor in the atmosphere so that rain clouds can easily form.

In addition, there is a cyclonic circulation that forms a pattern of wind bends in the northern region of Papua as well as a slowdown in wind speed that can increase convective activity and the growth of rain clouds in several areas in Papua in the next few days. The unstable atmospheric conditions entering the rainy season were observed along with the increasing frequency and intensity of rain in the Seasonal Zone.

Besides, the related parties and the community are expected to make preparations in order to minimize the impact of high rainfall such as floods, landslides, fallen trees, etc. by ensuring that infrastructure capacity and water resources management systems are ready to anticipate increased rainfall.

Carrying out environmental management by not littering and not cutting slopes or uncontrolled felling of trees and carrying out a more massive reforestation program.

Pruning the fragile tree branches and twigs and strengthening stands/poles so that they do not collapse in strong winds. Recognizing the condition of the living environment and increasing alertness when there is heavy rain with a long duration, especially people living in the foothills, hills, near riverbanks to residential areas prone to flooding due to poor drainage systems.
