BMKG: See you tomorrow, watch out for the possibility of high waves reaching 6 meters

KOMPAS.com- This is not about investigating the potential for a tsunami reaching 20 meters, but those of you who will be active in various Indonesian waters should be aware of the potential for high waves.

The Agency for Meteorology, Climatology and Geophysics (BMKG) issued an early warning for waves up to six meters high that are likely to occur in various areas of Indonesian waters from September 29-30, 2020.

The early warning was issued based on the results of BMKG analysis in the form of wind patterns in the northern part of Indonesia, usually from the southeast-southwest with wind speeds of 5-25 knots.

Furthermore, the highest wind speed was observed in the waters of Enggano Island, the western waters of Lampung, the southern Sunda Strait and the southern waters of Banten.
