TEMPO.CO, Jakarta - The Meteorology, Climatology, and Geophysics Agency (BMKG) said that the waves surrounding Nunukan Regency's waters in North Kalimantan could reach up to three meters - threatening small fishermen's boats as well as vessels with low-tonnage capacity.
Jamingi, a forecaster for Nunukan Regency's BMKG said on Tuesday that the warning have been issued by BMKG's Headquarters in Jakarta - advising residents to be aware when setting sail into the waters in the area, which borders the State of Sabah in Malaysia.
"We have received a warning from Jakarta that high waves between two to three meters have been observed near the Indonesian-Malaysian borders," said Jamingi.
The warning - which is based on a continuous observation which began six days ago - has caused several delays on speedboat journeys between Nunukan and Tarakan, beginning on Saturday, July 4, 2015.
BMKG said that the high waves are expected to last for another week - and as such, residents, especially fishermen and ships with lighter loads, have been advised to exercise caution when setting sail for the area.
Jamingi said that high waves are often observed in Nunukan near the months of July and August - as strong easterly winds often blows around the northern tip of Kalimantan during this period.
