On 31 January 2018, we will witness the rare natural phenomenon that is the total lunar eclipse alias Red blood moon, the phenomenon occurs along with the supermoon and blue moon.
When the phenomenon occurred on January 31, 2018, BMKG (Meteorology Climatology Geophysics Agency) appealed to the community, especially those on the beach and the fishermen to be aware of high tide maximum. Maximum can reach 100-140 centimeters and recede drinks 100-110 centimeters on 30 January to 1 February 2018.
Some of the coastal areas that are experiencing this high tide are North Sumatera, West Sumatera West, South Lampung, North Jakarta, North Central Java, North East Java and West Kalimantan.
Medium to Lush Rain Potency
In addition, some regions in Indonesia have the potential to experience moderate to dense rain within one week, from 29 January to 3 February 2018.
The main cause of this potential rainfall is the movement of cold air mass from mainland Asia that is still quite active in the cold index of cold air (cold surge). This led to the formation of several encounter regions of the wind that caused the growth of rain clouds to be significant.
A number of potential areas of moderate to heavy rainfall over a period of a week are Aceh, Jambi, Kep. Bangka Belitung, Lampung, Banten, West Java, Central Java, Yogyakarta, East Java, Bali, West Nusa Tenggara, East Nusa Tenggara, West Kalimantan, Central Kalimantan, East Kalimantan, North Kalimantan, Central Sulawesi, South Sulawesi, West Papua Papua.
Wind Speed and Sea Waves
In addition to the potential for heavy rains, an increase in wind speeds up to more than 20 knots potentially occurs in the Java Sea, the Indian Ocean south of Java Island, the Sunda Strait, the northern waters of Central Java, the northern waters of West Nusa Tenggara to East Nusa Tenggara, and the northern coast of Java.
The increase in wind speed also has an impact on the increase of sea waves in some areas as follows.
- 4 - 6.0 meters (Very Rough Sea) waves have the opportunity to occur in the South Indian Ocean to East Nusa Tenggara. Southern waters P. Sumba - P. Sawu - P. Rote - Timor Sea, Arafuru Sea
- Height of 2.5 - 4.0 meters (Rough Sea), potentially occur in Enggano waters, west of Lampung, south of the Sunda Strait, southern waters of Java, waters Kep. Sermata - Leti, waters Kep. Babar - Tanimbar.
Therefore, BMKG provides several appeals that need to be paid attention to the community in the affected locations. The appeal is as follows: - Be aware of potential puddles, floods or landslides for those living in areas with potentially heavy rainfall especially in flood prone areas and landslides.
- Be aware of the possibility of rain accompanied by wind that can cause trees or billboards fall / collapse.
- No shelter under the tree if the rain accompanied by lightning / lightning.
- Watch for high rise waves, rob potential and impact.
- Watch for heavy rain accompanied by strong winds that are harmful to small vessels.
- Delaying traditional fishing activities until high waves subside.
