BMKG through the Jakarta Tropical Cyclone Warning Center (TCWC) is monitoring two tropical cyclone seeds that formed in the Northern Hemisphere (BBU) of Indonesia.
The two cyclone seeds are 98W that appear in the Western Pacific Ocean and 99W in the South China Sea. BMKG Deputy Meteorologist Guswanto said the two cyclones had an impact on weather conditions in Indonesia.
“The seeds of Cyclones 98W and 99W are moving north-northwest away from Indonesian territory and it is expected that the intensity of both increases in the next 24 hours,” Guswanto said.
He explained, the indirect impact of cyclone 98W is the potential for ocean waves with a height of 1.25-2.5 meters in the Eastern Pacific Ocean of the Philippines.
Meanwhile, cyclone 99W could potentially result in moderate to heavy rainfall in North Kalimantan, East Kalimantan, Central Kalimantan, West Kalimantan, North Sulawesi, Gorontalo, and Central Sulawesi.
Even so, guswanto added, weather conditions in Indonesia are also affected by the Rossby Wave and Kevin Wave. In addition, slowing wind speeds also increase connectivity in the atmosphere and potentially cause rain clouds.
In addition, the potential for rain also occurs in West Kalimantan, Central Kalimantan, East Kalimantan, North Kalimantan, South Kalimantan, West Sulawesi, Central Sulawesi, South Sulawesi, Southeast Sulawesi, North Sulawesi, Gorontalo, North Maluku, Maluku, West Papua, and Papua.
