JAKARTA - The Meteorology, Climatology and Geophysics Agency (BMKG) reported early warnings regarding the potential for heavy rain accompanied by lightning and strong winds in North Kalimantan, Bali, Riau and most parts of Indonesia today, Thursday, December 1.

According to BMKG forecasts, moderate to heavy rain accompanied by lightning and strong winds has the potential to occur in the provinces of Aceh, Bali, Bangka Belitung, Banten, Bengkulu, Gorontalo, Jambi, West Java and East Java.

Parts of West Kalimantan, South Kalimantan, Central Kalimantan, East Kalimantan, North Kalimantan, Lampung, Maluku, North Maluku, West Nusa Tenggara, East Nusa Tenggara, Papua, and West Papua also have the opportunity to experience moderate to heavy rain which can be accompanied by lightning and strong winds.

Similar conditions have the potential to occur in the regions of Riau, West Sulawesi, South Sulawesi, Central Sulawesi, Southeast Sulawesi, North Sulawesi, West Sumatra, North Sumatra, and South Sumatra.

In addition, BMKG monitors the presence of two tropical cyclone seeds in eastern Indonesia, which can have an impact on weather conditions in a number of areas.

BMKG forecaster Rifat Darajat said the seeds of tropical cyclone 90W were observed around the North Maluku region, which formed an elongated convergence area in the Sulawesi Sea. The cyclone seeds have a maximum wind speed of 15 knots and a minimum air pressure of 1007.0 mb.

In addition, the seeds of tropical cyclone 95S were observed in Carpentaria Bay, which forms a low level jet that extends from the Arafuru Sea to eastern northern Australia.

"This condition is able to increase the potential for rain cloud growth, wind speed, and sea waves around cyclone seeds," said Rifat.

Heavy rains and strong winds can cause hydrometeorological disasters such as floods and landslides. According to BMKG, South Kalimantan and South Sulawesi are on standby to face the impact of heavy rains on December 1-2, it is West Kalimantan and South Sulawesi whose status is on standby to face the impact of heavy rains.
