Ireland: Adverse weather forecast nationwide June 20
Severe weather forecast across Ireland June 20. Possible transport, business, and utility disruptions.
Event
Heavy rainfall and thunderstorms are forecast nationwide on June 20. Significant rainfall is forecast over short periods during the afternoon June 20, and the heavy downpours could trigger flooding and associated disruptions. Strong wind gusts, lightning, and hail may accompany storms. As of June 20, Met Eireann has issued orange (the middle level on a three-tier scale) thunderstorm and rain warnings across the country through 18:00 June 20. Authorities will likely issue new alerts or update/rescind existing advisories as weather conditions change over the coming days.
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 or a lack of 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. Disruptions to electricity and telecommunications services are possible where significant flooding, strong winds, 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.
Severe weather could also trigger flight delays and cancellations at airports in the region. If strong winds trigger hazardous sea conditions, authorities may temporarily suspend port and ferry operations or close beach fronts. Flooding could block regional rail lines; freight and passenger train delays and cancellations are likely in areas that see heavy rainfall and potential track inundation.
Localized business disruptions may occur in low-lying areas; some businesses might not operate at full capacity because of flood damage to facilities and some employees' inability to reach work sites.
Advice
Monitor local media for weather-related updates and advisories. Out of an abundance of caution, confirm all transport reservations before travel in the affected area. Seek updated information on road conditions before driving or routing shipments through areas where severe weather is forecast; plan for possible supply chain disruptions throughout the affected areas. Stay away from elevated streams, creeks, and other watercourses that are prone to flash flooding. Do not attempt to navigate flooded roadways. Charge battery-powered devices in the case of prolonged electricity outages.
