Ecuador: Adverse weather forecast across central and eastern regions through at least July 19

Event

Adverse weather is forecast across much of central and eastern Ecuador through at least July 19. Ecuador's National Institute of Meteorology and Hydrology (INAMHI) has issued a weather warning for rainfall and thunderstorms from the afternoon of July 15 through the evening of July 19. The warning covers most of the Andean region down the central spine of the country and the Amazon region in the east. Up to 6.5 cm (2.5 inches) of rainfall per day is possible in some regions, and the heavy downpours could trigger flooding and landslides in affected areas.

Heavy rainfall July 3-6 resulted in flooding across central and eastern Ecuador, with the worst hit being Azuay, Tungurahua, and Zamora Chinchipe provinces. The Zamora River in Zamora Chinchipe Province and the San Francisco River in Gualaceo Canton, Azuay Province as well as the El Carmen River overflowed, causing damages to infrastructure. Multiple landslides blocked roads in Colepato, Huigra, Matrama, Mazar, and Zhoray communities. Further rainfall is likely to hamper recovery efforts or result in flooding and flash flooding over already saturated soils and rivers with high water levels.

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 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 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 region. Flooding could block regional rail lines; freight cancellations are possible in areas that see 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 has been forecast. Do not drive on flooded roads. Charge battery-powered devices in the case of prolonged electricity outages.
