Cyclone Mahasen made landfall on 16 May 2013 in Barisol, southern Bangladesh. After landfall, the cyclone quickly weakened and was downgraded to a tropical storm before dissipating over northern Bangladesh. A Phase 1 Joint Needs Assessment (JNA) found that 1,042,340 people were affected by the cyclone; roughly 25% of the population. The cyclone caused the displacement of up to 38,000 people and extensive damage to homes, with official estimates from the Disaster Management Information Center (DMIC) reporting a total of 118,792 shelters damaged. 

A few days into the emergency phase, REACH deployed a team to Bangladesh to support the Phase 3 Detailed Assessment, a joint initiative of the Government of Bangladesh and the Shelter, WASH, and Early Recovery Clusters. REACH team first collected secondary data from government and agency sources, which was integrated into the analysis for the final report. REACH also used the Joint Needs Assessment Phase 1 data to produce a series of maps and webmapsIn the end, assessment teams managed by REACH staff conducted household surveys in rural and urban/semi-urban areas among 4,615 households and key informant interviews in each of the communities visited. Tropical Storm Mahasen in Bangladesh: Phase 3 Shelter, WASH, Early Recovery Detailed Assessment thus aimed at providing contextual information regarding the impact of the typhoon at a community level, land and resettlement issues, economic impact of livelihoods, and location of highly affected populations.
