A. Situation analysis
Description of the disaster

Following an initial flooding event at the end of October, which receded quite quickly, heavy rain continuing in early November, saw a rapid escalation of the situation on 6 November 2021, causing extensive flooding across several districts. As six districts remain submerged in water the situation is overwhelming emergency responders in the area. This event comes at the beginning of a prolonged La Nina that Indonesia’s meteorological agency has indicated will significantly increase the risk of widespread flooding over the next few months in different parts of the country.

Around 991 households or 2,889 people are affected by the flood with water level around 20-50 centimeters. PMI continued conducting the assessment, to determine and identify displaced households in the area. The high inundation has been hampering the assess ment process, so it requires a longer time to collect more data.
COVID-19 Situation in Indonesia and the affected areas
Referring to WHO Indonesia COVID-19 situation report on 3 November 2021, weekly COVID-19 case incidence in all regions in Indonesia has remained at a low level of community transmission (CT1) for the past seven to eight weeks since October 2021. All provinces were at a low level of community transmission (CT1) during the week from mid to end of October 2021. Based on the WHO interim guidance, this means that there was a low risk of COVID-19 infection for the general population and a low incidence of locally acquired, widely dispersed cases detected in the past 14 days.
Immediate needs and challenges
The floods are still inundating most of the areas in the affected districts. As of 9 November 2021, PMI identified 22 evacuation centers across the area, occupied by approximately 4,179 people. Various organizations and local humanitarian organizations have been responding to the floods, providing assistance to the evacuation centers including food items and basic needs. However, the majority of the affected community continued staying in their houses and preferred seeking shelter from their relatives, as necessary. With most response agencies focusing on assisting the evacuation centers, most of the people staying in their houses have limited access to humanitarian assistance. Many of the houses are double story buildings, so the affected people/households are staying in the upper level of their houses during the flooding. However, since heavy rain continues in the area, there remains a possibility that the water level will continue to rise. If flood waters continue to rise, those who are currently staying in their houses will have to evacuate their houses and seek shelter at evacuation centers or stay with their relatives.
