Bangladesh, Myanmar: Disruptions due to Cyclone Mocha ongoing across parts of Rakhine State, Myanmar, and Chittagong Division, Bangladesh, as of May 15

Event

Disruptions are ongoing across coastal areas of southeastern Bangladesh and northwestern Myanmar as of May 15 following the passing of Cyclone Mocha. The storm crossed the coast between Kyaukpyu township in Myanmar's Rakhine State and Cox's Bazar in Bangladesh's Chittagong Division as a Very Severe Cyclonic Storm around midday MST May 14. The storm weakened rapidly upon making landfall, and it transitioned into a low-pressure area as it tracked across northern Myanmar and into Yunnan Province, China, on May 15; however, severe impacts have been reported along coastal areas in the vicinity of where the storm made landfall.

Parts of western Rakhine State around the state capital Sittwe have been worst affected by the storm. Heavy rainfall, strong winds, and storm surge triggered flooding and landslides in the region. As of late May 15, authorities have reported at least six fatalities; around 700 others have been injured. The storm has caused extensive damage in the area, with 90 percent of Sittwe reported to be affected. Widespread communication failures caused by the storm mean the full extent of the damage in the region is still being assessed. Early reports indicate at least 850 homes have been destroyed or damaged by the storm; casualty and damage figures will likely rise over the coming hours and days. Authorities have declared Rakhine State a natural disaster area following the storm's impact.

Authorities in Bangladesh have reported at least 13,000 homes were destroyed or damaged in Cox's Bazaar District (including St Martin's Island), Chittagong Division, following the passing of the storm. Around 15-20 people suffered minor injuries, and flooding and landslides have been reported in the region. Authorities had evacuated hundreds of thousands of people in the most at-risk areas ahead of the storm's approach. Damage assessments are ongoing.

Protracted transport and business disruptions are almost certain in affected areas as emergency crews continue recovery efforts; utility disruptions will probably occur over the coming days and weeks. Shortages of fuel and other essential goods are likely. Driving conditions may be difficult on rural routes and regional highways.

Stagnant pools of water during and after flooding may increase the incidence of insect-borne and waterborne diseases, such as dengue fever, cholera, and malaria. Exposure to raw sewage and other hazardous materials mixed with floodwaters poses a serious health threat.

Advice

Monitor local media for updates and advisories on weather conditions. Make allowances for possible supply chain disruptions in affected areas. Do not drive on flooded roads. Use extreme caution in low-lying areas and near streams, creeks, and other waterways due to the potential for flooding. Seek updated information on road conditions before driving or routing shipments through areas where flooding has occurred. Confirm flights before checking out of hotels or driving to the airport; clearing passenger backlogs may take several days in some locations. Prepare for possible communication disruptions, including to mobile phone and internet services.

Observe strict food and water precautions, as municipalities could issue boil-water advisories following flooding events. Take precautions against insect-borne and waterborne diseases in the coming days. Review contingency plans and be prepared to move quickly to shelters if evacuation orders are issued. Charge battery-powered devices in the case of prolonged electricity outages.
