Figure 3: Past 7 day (24Jul-30Jul) percent of normal rainfall Rainfall in the past 7 days Figures 3 and 4 illustrate the per- cent of total rainfall and rainfall anomaly in the past 7 days (24-30 July 2017). The majority of the Country received higher than nor- mal rainfall, from the north west down to the southern parts of the country. Extremely heavy rainfall occurred in Xayabury down to Vientiane Province and Vientiane Capital, in the eastern parts of Borikhamxay, Khammuane, western parts of Sa- vannakhet province, and the west- ern parts of Saravane province. Similarly, other parts of the rest of central and Southern provinces received higher rainfall than nor- mal due to the impact of the tropi- cal storm SONCA. Food security estimate The ASEAN One Response Centre estimated on the 25th July that their were approximately 1,872 affected families, 88 affected houses, 188 displaced persons and 3 deaths. The floods had already damages approximately 2,535ha of agriculture and fisheries. These numbers are expected to rise as updated data comes in. WFP is now working with partner (UN-OCHA) to estimate the level of food insecurity through remote sensing techniques. Within this week, the impact to food security could be estimated. Currently, there is no food assistance requested from Government. However, local Govern- ment has provided assistance on water, some food, and housing material to the most af- fected people. 2 August 2017 Rainfall & Flood Forecast Figure 5: Global Flood Detection System 31 July’17 Tuesday sees reduced rainfall to the majority of the country largely a result of the dissipating tropical storm SONCA. This should alleviate flooding conditions in affected areas however, the southern prov- inces of Champasak, Attapu and Sekong are expected to receive heavy rainfall through Tuesday night increasing flood and food insecurity risk. On Wednesday heavier rainfall can be expected in the southern parts of the country with heavy rainfall expected in Savannakhet, Saravan, Champasak, Attapu and Sekong. Thursday brings continued rainfall to the southern provinces of Saravan, Cham- pasak, Attapu and Sekon and heavy rainfall to the central provinces of Khammouan, Bolikhamxay and Vientiane Provinces. The rainfall forecast for Friday sees continued heavy to extremely heavy rainfall in the southern provinces of Saravan, Champasak, Attapu and Sekon and in Khammouan Province. This consistent heavy rainfall in the central and southern parts of the country, particularly in the Sar- avan, Champasak, Attapu and Sekong provinces will exacerbate current flooding in high risk zones as identified in Figure 5 and would continue to inundate hectares of agricultural areas. This trend is also reflected in the Mekong river water level on 31 July 2017 where Pakze remains at alarmingly high level. Due to continued heavy to extremely heavy rainfall expected over the next 5 days, WFP and partners should continue to monitor the situation and liaise with Government departments and district officials to identify areas and estimated numbers of people affected.
