BMKG: Beware of Coastal Flooding in NTT Coasts on 22-24 March 2026
Kupang, NTT (ANTARA) - The Meteorology, Climatology, and Geophysics Agency (BMKG) has urged the public to be vigilant against the potential occurrence of coastal flooding or rob in the Nusa Tenggara Timur (NTT) province from 22-24 March 2026.
“Coastal communities are advised to be alert to the potential coastal flooding phenomenon (rob) predicted to occur from 22-24 March 2026 in several water areas in NTT,” said the Head of the Tenau Kupang Maritime Meteorology Station, Yandri Anderudson Tungga, in Kupang on Sunday.
He mentioned that the areas potentially affected by rob flooding include the coasts of Flores-Alor Island, Sumba Island, Sabu-Raijua Island, and Timor-Rote Island.
“This condition is caused by the new moon phase on 19 March 2026 and the perigee phase on 22 March 2026, which have the potential to increase the maximum sea level height,” he stated.
Based on tide predictions, wind speed, wave height, and potential moderate to heavy rain data, he continued, these factors will also influence coastal dynamics in NTT in the form of potential rob flooding.
Yandri also explained that rob flooding is an event where the sea surface rises onto coastal land caused by high tides or heavy rainfall, resulting in surrounding areas being inundated by seawater.
This condition, he said, can impact community activities around ports and coasts, such as loading and unloading at ports, salt pond and onshore fishing activities, as well as other economic activities.
“Particularly for communities in affected coastal areas, increase vigilance and follow official and up-to-date information from BMKG,” he said.
BMKG also urges sea transport users to be aware of potential waves reaching 2.5-4.0 metres that may occur in the waters south of Sabu-Raijua and north of Sabu-Raijua from 22-25 March 2026.
