Meteorology, Climatology and Geophysics Agency (

) said that Indonesia is currently not truly safe from danger
tropical cyclone
, even though it is at the equator.This was demonstrated by Tropical Cyclone Senyar and a number of other tropical cyclones several years ago.
“As Indonesian waters continue to warm which has given rise to low pressure which triggers the emergence of cyclone seeds, cyclones or low pressure patterns, of course we have to be aware that this can no longer happen, meaning that Indonesia will be safe from cyclone trajectories,” said BMKG Director of Public Meteorology Andri Ramdhani in an online press conference, Wednesday (26/11).

Tropical Cyclone Seed 95B in the Malacca Strait has transformed into Tropical Cyclone Senyar on Wednesday (26/11).This tropical cyclone has the potential to land in Aceh in the next 24 hours.
Andri said the presence of Tropical Cyclone Senyar in Indonesia was a rare event.In theory, he said, Indonesia is a region that tropical cyclones will not pass through, because it is in the equatorial region.
However, he said the records of the last five years did not show this.According to him, many tropical cyclones are starting to approach Indonesian territory.
“For example, in 2021 with cyclone Seroja, it really entered land areas. Then there was also tropical cyclone Cempaka in the south of Yogyakarta. Then also Dahlia,” he said.
Furthermore, Cyclone Senyar currently has a center at 5 degrees N and 98 degrees E with a minimum air pressure at the center reaching 998 hPa.This tropical cyclone has a maximum wind speed of 43 knots or around 80 km/hour.
This tropical cyclone is moving west towards the Aceh mainland at a speed of around 10 km/hour and triggers the growth of convective clouds in the surrounding area.
As a result, the weather in the areas where this tropical cyclone passes will be significantly affected.Faisal said that the Aceh and North Sumatra regions had the potential to receive very heavy to extreme rain which could be accompanied by strong winds.
Apart from increasing the intensity of rain, Tropical Cyclone Senyar also has the potential to cause high sea waves of 2.5-4 meters in the northern Malacca Strait, Aceh waters and the West Indian Ocean from Aceh to Nias;and medium category waves of 1.25 to 2.5 meters in the central part of the Malacca Strait, North Sumatra waters and Rokan Hilir waters.
The Tropical Cyclone is expected to continue moving west and southwest and interact with land, then is expected to gradually weaken.
However, extreme weather still has the potential to occur as a further impact, so the potential impact of hydrometeorological disasters such as floods, flash floods, landslides must still be watched out for in the areas of Aceh, North Sumatra, Riau Islands, West Sumatra and surrounding areas in the next 2 to 3 days.
The impact of this tropical cyclone causes extreme weather impacts such as heavy rain, strong winds, coastal flooding (rob), landslides and fallen trees in densely populated areas.
“If the center of a cyclone enters land, it is ready to cause damage, extreme rainfall and strong winds have the potential for flooding and landslides in the areas it passes,” explained BMKG Deputy Guswanto.
Under certain conditions, BMKG and BNPB often use Weather Modification Technology (TMC), to reduce rainfall.However, this technology cannot be applied to large-scale systems such as tropical cyclones.
“The escalation is too big, the movement is fast, and the risk is very high for the safety of the team, what can be done is mitigation and preparation,” said BMKG.
BMKG emphasized that people must start adapting to the new era of weather patterns in Indonesia, where the threat of tropical cyclones is increasingly occurring.
