Description: Heavy rain has been affecting several areas of the country over the last days, causing flash floods.
As of 15 February, local media reported 500 people displaced, at least 80 houses damaged and traffic disruptions in the municipalities of Sambelia (West Nusa Tenggara province) and Kedungsumber (East Java province).
This flood is expected to have a low humanitarian impact based on the magnitude and the affected population and their vulnerability.
- Duration: 10/02/17 to 15/02/17
- Impact: 0 killed and 500 displaced
- regions: Nusatenggara Barat, Jawa Timur
- Severity: class 1 (i.e. large flood event with significant damage to structures or agriculture; fatalities; and/or 1-2 decades-long reported interval since the last similar event)

Flood polygons: This polygon (translucent blue with a blue border) is drawn by the analysts recording the flood event. It is meant to include all the areas reported as affected, by official source or the media. It does not represent the area actually under water.
Microwave flood detection: Flooded area, as detected in microwaves by the Global Flood Detection System of the JRC, based on NASA TRMM/GPM observations. This system has a rather low resolution (of 5-10km) but is not affected by clouds. For more details, see http://www.unisdr.org/files/9622_LBNA23303ENC002.pdf. The areas with a flood signal along the coast are an artefact of the system and should not be considered.
Optical Flood detection: Flooded area as detected in optical wavelengths by NASA/MODIS, known as "MODIS Flood Product". Data are made available by NASA GSFC Flood Mapping Project, http://oas.gsfc.nasa.gov/floodmap/index.html. Resolution of 250m, heavily affected by cloud cover.
Rain: Rainfall accumulaiton of the past 24h, as detected by the Global Precipitation Measurement mission of NASA. For more information, see https://www.nasa.gov/mission_pages/GPM/main/index.html.
