Sidoarjo, en.SERU.co.id – The Meteorological, Climatological, and Geophysical Agency (BMKG) Class I Juanda has urged residents of East Java (Jatim) to remain vigilant. Weather monitoring indicates that from March 26 to April 4, 2026, East Java has the potential to be hit by extreme weather conditions.
Taufiq Hermawan, Head of BMKG Class I Juanda, stated that the extreme weather occurring in several areas of East Java could trigger hydrometeorological disasters such as moderate to heavy rain, flooding, flash floods, landslides, strong winds, waterspouts (puting beliung), and hail.
“It is predicted that over the next 10 days there will be an increase in extreme weather that will significantly impact community activities,” he said.
He explained that parts of East Java are currently entering the transition period from the rainy season to the dry season, which often brings potential for extreme weather and hydrometeorological disasters.
“This is the impact of disturbances from Rossby Waves and Kelvin Waves crossing the East Java region, where sea surface temperatures generally show significant evaporation activity in the Madura Strait,” he added.
According to BMKG observations, there is also an indirect impact from Tropical Cyclone Narelle currently located in the Indian Ocean west of southern Australia and Nusa Tenggara Barat, combined with locally unstable atmospheric conditions that support the growth of convective clouds.
“These phenomena have the potential to cause moderate to heavy rain accompanied by thunder and strong winds,” he noted.
Taufiq urged the public and relevant agencies to always be alert to sudden weather changes and the potential for extreme weather in the form of moderate to heavy rain accompanied by thunder and strong winds over the next 10 days.
In addition, communities in areas with steep topography, mountains, and cliffs are advised to be extra cautious of impacts from hydrometeorological disasters.
“The public is also encouraged to continuously monitor current weather conditions via the WOFI weather radar imagery on the website https://stamet-juanda.bmkg.go.id/radar/, as well as the 3-daily early warnings and 2-3 hour nowcasts that we regularly issue,” he concluded. (wul/ono)
