UK, Ireland: Adverse weather forecast across northern and central UK and Ireland through at least Feb. 24
Heavy rainfall and strong winds forecast across central and northern UK and Ireland through at least Feb. 24. Disruptions possible.
Event
Heavy rainfall and strong winds are forecast across Ireland the northern and central UK, including parts of Scotland, Wales, western England, and Northern Ireland, through at least Feb. 24. As of Feb. 23, authorities have issued orange-level warnings for heavy rainfall for portions of northern and southern Scotland and southwestern Ireland. Additionally, yellow-level warnings for heavy rainfall and strong winds are in effect across the affected area. Authorities will likely expand coverage of the advisories as the systems approach and 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 the soil has become saturated by heavy rainfall. 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.
Severe weather could also trigger flight delays and cancellations at regional airports. Authorities may temporarily suspend port operations or close beach fronts along the Irish, North, Bering, and Celtic Seas if strong winds trigger hazardous sea conditions. 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 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.
