The Surabaya Rob Flood Will Occur Until June 17, 2022, The Peak Is In 2 Days

JAKARTA - The Tanjung Perak Maritime Meteorology, Climatology and Geophysics Agency (BMKG) predicts tidal flooding or high tides to occur in the city of Surabaya and parts of the coastal areas of East Java from Monday to June 17, 2022.

"The peak of the tidal flood will occur on June 15, where the height of the tidal flood is at level 160 of the average sea level. This condition will cause inundation in coastal areas to reach 30 to 40 cm," said BMKG Maritime Forecaster Tanjung Perak Surabaya Fajar Setiawan in Surabaya, Monday 13 June.

The tidal flood causes the flow of rivers to the sea to be blocked. What's more, this condition can be exacerbated by the La Nina phenomenon.

Even though it is now the dry season, the potential for rain is still higher.

"If all three occur simultaneously, there is rain, the tide continues, then automatically the water in the river will be even more difficult to flow into the sea," he said.

Fajar explained that recently the condition of the sea water is still warm. Therefore, he said, rain will often occur even though the intensity is light to moderate if on land. While conditions at sea, the intensity of rain can reach the moderate to heavy category.

"Because it's currently La Nina, so we predict that until the end of next year, even though the dry season will still often rain. Most people call it a wet dry season," he said.

He said, La Nina was actually a global phenomenon that did not only hit the East Java region. However, he continued, if La Nina was more intense in Indonesia, especially the Central and Eastern parts.

"So starting recently, we predict that the sea surface temperature will warm until the end of the year. So, until the end of the year, God willing, the rainfall will still occur frequently," he said.

Therefore, he said, his party appealed to the community, especially those living on the coast, to increase their vigilance because currently the supply of water vapor in Indonesian territory is still large, so rains will often occur.

BMKG Data and Information Coordinator Juanda Sidoarjo Teguh Tri Susanto said, currently there is a global La Nina phenomenon that is still ongoing and the phenomenon of warmer sea surface temperatures around the East Java region.

Teguh reiterated that the BMKG predicts that the potential for rain will continue throughout 2022. However, he advised that wet dry conditions due to this climate anomaly cannot be used as a benchmark for this to happen forever.

"This is an overview, for strengthening it can continue to monitor weather developments on a meteorological scale (1 daily, 3 daily, 7 daily) on official channels or BMKG contacts," he said.

Head of the Regional Disaster Management Agency (BPBD) for the City of Surabaya, Ridwan Mubarun, said that currently BPBD personnel have been deployed to deal with flooding in Surabaya.

According to Ridwan, all the water pumps owned by the Surabaya City Government have been turned on. It's just that, he continued, the current condition of the tide is that it cannot be dumped into the sea.
