Ecuador: Adverse weather forecast across central, eastern, and northwestern regions through at least early Oct. 20

Event

Adverse weather is forecast across much of Ecuador through at least early Oct. 20. As of early Oct. 17, Ecuador's National Institute of Meteorology and Hydrology (INAMHI) has issued a weather warning for rainfall and thunderstorms across northern and central parts of the western coastal regions, parts of the foothills of the central Andean mountain region, and much of the eastern Amazonian region. Officials have issued orange warnings (the middle level on a three-tier scale) across parts of northwestern Carchi, central, eastern, and southern Esmeraldas, northern and western Imbabura, far northern Los Rios, northeastern Manabi, western Pichincha, and much of Santo Domingo de los Tsachilas provinces. Rainfall accumulations of 2.5-5.5 cm (1-2 inches) are forecast in the orange warnings areas. Yellow warnings are in place across the rest of the affected area. Strong wind gusts and lightning may accompany storms.

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.

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.
