Ukraine: Adverse weather forecast across central and western regions July 18

Adverse weather is forecast over central and western Ukraine July 18. Heavy rainfall and thunderstorms are forecast across the region; strong wind gusts, lightning, and hail may accompany storms. The Ukrainian Hydrometeorological Center has issued orange heavy rainfall warnings (the middle level on a three-tier scale) across Kyiv Oblast, including the city of Kyiv, through late July 18. Rainfall amounts of 3-4 cm (1.2-1.6 inches) per hour are possible in the region. Yellow thunderstorm, hail, and squally wind warnings are in place across the affected area; winds gusting up to 72 kph (45 mph) are expected across the affected regions. Yellow hydrological warnings (the second lowest level on a fiver-tier scale) for increasing river levels and mudflows are in place for river catchments in parts of Ivano-Frankivsk, Lviv, and Zakkarpattia oblasts July 18. Authorities will likely issue new alerts or update/rescind existing advisories as weather conditions change over the coming hours.

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 rain 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.

The severe weather could contribute to transport disruptions throughout the region. Traffic and commercial trucking delays might occur along regional highways. Flooding downpours could inundate some low-lying roads in areas with poor drainage. Strong winds might also pose a hazard to high-profile vehicles. Hazardous weather conditions might cause flight delays and cancellations at airports in affected areas.
