Ecuador: Adverse weather forecast nationwide through at least April 4

Event

Adverse weather is forecast nationwide through at least April 4. As of March 31, Ecuador's National Institute of Meteorology and Hydrology (INAMHI) has issued a weather warning for rainfall and thunderstorms across the country through late April 4. The most intense rainfall is forecast in interior parts of the western coastal region from March 31-April 1, with heavy rainfall also forecast in the foothills of the eastern Amazon region. Rainfall of varying intensity with occasional heavy downpours is expected in the central Andean region and light-to-moderate rainfall is forecast over the Galapagos Islands.

Red warnings (the highest level on a three-tier scale) have been issued across parts of northwestern and far eastern Azuay, northern and western Bolivar, western Canar, western Carchi, western Cotopaxi, central, eastern, and southern Esemeraldas, eastern, northern, and southwestern Guayas, far western Imbabura, Los Rios, eastern Manabi, central and southwestern Morona Santiago, eastern Napo, western Orellana, northwestern Pastaza, western Pichincha, southern Santa Elena, Santo Domingo de los Tsachilas, and western Sucumbios 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 up to 8 cm (3 inches) in the Amazonian region. Storms may be accompanied by strong wind gusts and lightning.

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.
