Ecuador: Adverse weather forecast across much of the country through at least April 7

Event

Adverse weather is forecast across much of the country through at least April 7. As of April 5, Ecuador's National Institute of Meteorology and Hydrology (INAMHI) has issued a weather warning for rainfall and thunderstorms across most of the country, with the exception of some eastern Amazonian regions, through the morning of April 7. The most intense rainfall is forecast in the interior and southern parts of the western coastal region late April 5-6. Rainfall of varying intensity and possible thunderstorms are expected in the central Andean region and the foothills of the eastern Amazonian region. Scattered showers are also forecast in the Galapagos Islands.

Red warnings (the highest level on a three-tier scale) have been issued across parts of western Azuay, western Bolivar, western Canar, southwestern Cotopaxi, eastern and southern Esemeraldas, El Oro, Guayas, far southwestern and western Imbabura, Los Rios, western Loja, eastern Manabi, northwestern Pichincha, southern Santa Elena, and Santo Domingo de los Tsachilas provinces; orange and yellow warnings are in place across the rest of Ecuador. Daily rainfall totals up to 10 cm (4 inches) are possible in parts of the coastal region and totals of 1-5 cm (0.4-2 inches) are likely across much of Ecuador over the coming days. Strong wind gusts and lightning may accompany storms.

Hazardous Conditions
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 heavy rainfall has saturated the soil.

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.

Transport
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. The disruptive weather may cause some delays and cancellations at airports in the affected regions. Flooding could block regional rail lines; freight cancellations are possible in areas with heavy rainfall and potential track blockages.

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

Advice

Monitor local media for weather updates and related advisories. Confirm all transport reservations and business appointments before travel. Make allowances for localized travel delays and potential supply chain disruptions where flooding is forecast. Do not drive on flooded roads. Charge battery-powered devices in the case of prolonged electricity outages.
