Bruce Tropical Cyclone Affected Extreme Weather and Flooding in East Java

Bengawan Solo River overflowed and inundated at least 11,188 houses across 115 villages within 15 sub districts of Bojonegoro District,  East Java, on 21 December. The floods claimed three casualties and caused temporary displacement to around 1,675 persons in 10 displacement centres. Additonally, the floods also caused medium damages in 1,630 houses and light damages in 1,006 houses. Approximately 67 schools were inundated: 26 kindergarten schools,  34 elementary schools, 5 junior high schools,  and two senior high schools. Bojonegoro is forecasted to experience raining with medium intensity on 22 December. 
 
Local BPBD already set up public kitchens as they distributed food items to the displaced families. According to 2010 statistics,  Bojonegoro District is home for 335,278 families or 1,209,973 persons with 598,365 men and 611,608 women.

East Java, together with southern part of Central Kalimantan,  Maluku and Papua has been forecasted to experience extreme weather with heavy raining, thunderstorm and whirlwind for 20-22 December, following the emerging tropical cyclone Bruce at approximately 2,540 km southwest Kerinci that moves to the south away from Indonesia region with maximum speed at 110 knots or 205 km/hour. The cyclone was also predicted to cause high tide with 2-3 meters high in the sea water of Sabang, Simeulue, Nias, Mentawai,  Enggano, Bengkulu,  Lampung,  Sunda, Banten, Central Java, West Sumatra and southern part of Java. Rainfall intensity (even more during extreme weather),  sea water surface (high tide) and water flow and absorption capacity of the land are three controlling factors that would trigger flooding.
