Zimbabwe sea port map11/29/2023 ![]() ![]() At the time of writing, there have been 138 confirmed cases of cholera in the port city of Beira, which has a population of ~500,000 (Beaumont, 2019b Reuters, 2019). (Data source: ReliefWeb).Īn additional concern is the number of cholera cases, which is increasing daily. 220,000 people have been displaced from their homes in all three countries, and more than 2.6 million are believed to have been affected by the event (Figure 4) (Maclean, 2019).įigure 4: Number of people affected in Zimbabwe, Mozambique and Malawi due to the floods caused by Cyclone Idai. However, these figures are expected to increase rapidly over the coming days as flood waters start to recede and the scale of the catastrophe becomes clearer (Beaumont, 2019). Mozambique has suffered the most reported fatalities (447), with 172 deaths in Zimbabwe and 59 in Malawi (OCHA, 2019c). Based on data released by ReliefWeb on 26 March 2019, a total of 678 deaths have been reported. The United Nations (UN) has identified the cyclone event as one of the worst disasters to occur in the southern hemisphere (Maclean, 2019). (Data source: NASA PPM, 2019 video produced by JBA Risk Management Limited™). Prolonged rainfall inundated the surroundings of Beira: total rainfall across the five-day period from 13 to 18 March ranged from 250–660mm (Figure 3 Video 1).įigure 3: Rainfall accumulation from 13-15 March 2019, based on daily precipitation data collected by NASA Precipitation Measurement Missions (left) and video (right) showing daily rainfall between 5 and 10 March 2019. The extent of flooding observed in the Buzi river basin based on JBA’s flood map is comparable to the flood extent observed by satellite data. The prolonged rainfall caused flash (surface water) and riverine flooding in the Chipinge and Chimanimani districts in Zimbabwe, as well as in Malawi and Mozambique (Figure 2).įigure 2: Extent of flooding seen from satellite imagery (left image source: ReliefWeb) compared with JBA’s 1-in-100-year Mozambique 30m river flood map for the area around the Buzi river basin in east Mozambique (JBA Risk Management Limited™). The landfall of Cyclone Idai resulted in extreme levels of precipitation and strong winds across south-east Africa, predominantly affecting Mozambique, Malawi and Zimbabwe (Reid, 2019). Cyclone Idai track data source: Météo France, 2019. The grey lines represent storm tracks recorded between 20 on JWTC track database. The intense tropical cyclone made landfall close to Beira, a port city in Mozambique. While moving westward in the Mozambique Channel, the tropical depression developed into an intense tropical cyclone.įigure 1: Track of Cyclone Idai from 4-16 March 2019. It first made landfall in north Mozambique before returning to the Mozambique Channel and re-intensifying (Figure 1). ![]() Cyclone Idai had originally developed as a tropical depression in the Mozambique Channel - an area of warm water located between Mozambique and Madagascar. Cyclone Idai made landfall near the city of Beira in Mozambique around midnight (CAT) on 15 March 2019 with wind speeds of up to 177km/hr (Beaumont, 2019a). ![]()
