JAKARTA - The Meteorology, Climatology and Geophysics Agency (BMKG) detected the emergence of tropical cyclone seeds 93W in the North Pacific Ocean, North Maluku which has the potential to affect weather and sea waves in Indonesian territory in the next few days.

Deputy for Meteorology Guswanto said the 93W tropical cyclone seeds were precisely at around 7.9 deg. 128.9 longitude east with a maximum wind speed of 20 knots, a minimum air pressure of 1005.4 millibars (mb).

"The Himawari-9 satellite image of the Enhanced-IR channel shows a decrease in convective cloud activity in the last six hours," he said as quoted by ANTARA, Tuesday, May 2.

He explained that environmental conditions around the system that support seed growth include warm sea level temperatures ranging from 30-32 degrees Celsius, and moderate to strong vorticity in the lower to middle layers.

From the global scale NWP model, he continued, it shows the system's propagation to the northwest towards the mainland of the Philippines.

BMKG estimates that the potential of these seeds to grow into tropical cyclones in the next 24 hours will be in the low category.

The indirect impact in the next 24 hours of cyclone 93W seeds on weather conditions in Indonesia, namely moderate to heavy rain in North Sulawesi and North Maluku.

In addition, the indirect impact of the 93W cyclone seeds affects the wave height of 1.25-2.5 meters in the Bitung-Sitaro Islands waters, Sangihe-Talaud waters, northern Maluku Sea, western and eastern waters of the Halmahera Islands.

The Halmahera Sea, Morotai waters, northern Raja Ampat waters, Manokwari waters, Biak waters, Jayapura-Sarmi waters, the northern Pacific Ocean, West Papua-Papua.

The public is advised to be vigilant and careful of the impacts that can be caused, BMKG continues to monitor the possibility of potential tropical cyclones that can have an impact on weather conditions in Indonesian territory.
