Mozambique: Adverse weather forecast across Manica, Sofala, and Tete provinces through at least April 10

Severe weather is forecast across central Mozambique through at least April 10. Heavy rainfall accompanied by thunderstorms and strong winds is forecast across Manica, Sofala, and Tete provinces; rainfall totals of 3-5 cm (1.2-2 inches) with localized heavier amounts are expected across the region. As of April 9, Mozambique's National Institute of Meteorology (INAM) has issued orange severe weather warnings (the middle level on a three-tier scale) for Manica, Sofala, and Tete provinces. Authorities will likely issue new alerts as weather conditions change over the coming days.

Sustained heavy rainfall could trigger flooding in low-lying communities near rivers, streams, and creeks. Urban flooding is also possible in developed areas with easily overwhelmed stormwater drainage systems. Sites located downstream from large reservoirs or rivers may be subject to flash flooding after relatively short periods of intense rainfall. Landslides are possible in hilly or mountainous areas, especially where the soil has become saturated by heavy rainfall.

Authorities could issue mandatory evacuation orders for flood-prone communities over the coming days. Disruptions to electricity and telecommunications services are possible where significant flooding or landslides impact utility networks.

Floodwaters and debris flows may render some bridges or roadways impassable, impacting overland travel in and around affected areas. Ponding on road surfaces could cause hazardous driving conditions on regional highways. Authorities could temporarily close some low-lying routes that become inundated by floodwaters.

Severe weather could also trigger flight delays and cancellations at regional airports. Authorities may temporarily suspend port operations or close beach fronts if strong winds trigger hazardous sea conditions. Flooding could block regional rail lines; freight and passenger train delays and cancellations are likely in areas with heavy rainfall and potential track inundation.

Localized business disruptions may occur in low-lying areas; some businesses might not operate at full capacity because of flood damage to facilities, possible evacuations, and some employees' inability to reach work sites.
