Bali Warned to Expect Extreme Weather for Week of January 12, 2020

WEATHER BULLETIN: Bali to Experience Extreme Weather Conditions for the Week Starting January 12, 2020

In the week starting Sunday, January 12, 2020, Bali is forecast to experience extreme weather conditions. As reported by Balipost.com, over the coming week, much of the Island’s landmass can expect to experience light to heavy rainfall accompanied by lightning, thunderstorms and strong winds.

Although the amount of rainfall will vary across the various sub-sections of Bali, the public is being warned by weather and emergency preparedness officials to be on guard for the threat posed by strong winds and rains expected to buffet the province over the coming week.

The strongest winds are expected primarily across the southern portions of the Island with off-shore waves of 2.5 meters or more expected to disrupt shipping, commercial fishing, water sports, and shoreline activities in South Bali, the Bali Straits, the Lombok Straits, the Indian Ocean surrounding the Island’s south.

Bali and many other parts of Indonesia will fall victim to a periodic atmospheric condition known as the Madden-Julian Oscillation (MJO) – a major fluctuation in tropical weather caused by an equatorial eastward-moving “pulse” of clouds and rainfall, sometimes referred to as “intra-seasonal tropical climate variability.”

Analysis by the Meteorological, Climate and Geophysics Agency (BMKG) indicates that the MJO will affect weather in central and eastern Indonesia for the coming week bringing rain, heavy winds and the formation of cyclonic weather systems.

Sumatra and Kalimantan will be most affected by this extreme weather situation. BMKG warns, however, that medium to heavy rains, thunderstorms with lightning, and strong winds can be expected in other areas, including Bali. Waves of more than 2.5 meters will be experienced on a line of weather stretching across the southern regions of Bali, West Nusa Tenggara, East Nusa Tenggara, and the North Natuna Sea.

The public is warned to exercise caution in the face of extreme weather conditions that can create flooding, landslides, flash flooding of rivers, large puddles and ponds, strong winds, falling trees, and slippery roadways. People living in coastal areas should be prepared for large destructive waves.

People should also be on the lookout for large, older trees in residential areas that may become uprooted and fall during this period of heavy rains and strong winds. Once soil around large trees becomes heavily saturated with rainwater, the “holding power” of the soil can be greatly diminished resulting in the trees succumbing to heaving winds and falling down. In the past, large trees in Denpasar and other residential areas of Bali have fallen during periods of similar weather resulting in death, injuries and property damage.
