With Brunei Darussalam entering the Northeast Monsoon, rainy weather is expected to persist until March 2021.
“The first two months of the Northeast Monsoon (December and January), usually known as the rainy season, normally have the highest amount of rainfall as compared to other months,” said the Brunei Darussalam Meteorological Department (BDMD) in a weather update yesterday.
“The average monthly rainfall for December is 345mm, while for January, it is 308mm (the average rainfall is for a period of 30 years, between 1981 and 2010).
“During this period, unsettled weather conditions with occasional heavy showers or thundershowers are expected, especially during the night and early morning.
“During the second half of the Northeast Monsoon (February and March), the atmospheric conditions tend to more stable with lesser rainfall. The average monthly rainfall for February is 157mm, while for March it is approximately 130mm (the average rainfall is for a period of 30 years between 1989 and 2010).”
The public is reminded to be aware that the risk of landslides is high in such weather conditions, along with flooding in low-lying or flood-prone areas, especially when heavy rainfall occurs for more than two hours.
Severe flooding may also occur during downpours, coinciding with high tides, while strong surges from the Northeasterly wind are expected to increase wave heights in Brunei waters to a rough state of up to three metres.
The public, road users and fishermen are advised to stay informed on the latest weather forecasts, advisories and warnings issued by the BDMD.
They are also urged to take precautions to ensure safety.
