Mauritius: Adverse weather forecast across much of the country through at least Jan. 25

Severe weather is forecast across much of Mauritius through at least Jan. 25. A low-pressure area located around 200 km (124 miles) to the northeast of the island of Mauritius Jan. 23 is expected to strengthen and may develop into a tropical storm as it moves southwards and passes east of Mauritius through Jan. 24 The system will bring strong winds, heavy rainfall, and thunderstorms to both Mauritius and Rodrigues islands over the coming days. Rough seas are also expected in coastal areas. As of Jan. 23, the Mauritius Meteorological Service has issued a Class 2 (out of 4) Cyclone Warning for Mauritius main island and a Class 1 Cyclone Warning for Rodrigues Island. Schools have been closed across Mauritius Jan. 23-24 and public sector employees have been advised to work from home. Most main bus services will be running a reduced service 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 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, rail networks, 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, including Sir Seewoosagur Ramgoolam International Airport (SRU). Authorities may temporarily suspend port operations or close beach fronts if strong winds trigger hazardous sea conditions.

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.
