US: Flash flood warning in effect for parts of the greater Pittsburgh, Penn., area until at least 23:00 Aug. 12
Flash flood warning issued for parts of the greater Pittsburgh, Penn., area, US, until at least 23:00 Aug. 12. Disruptions possible.
Event
The US National Weather Service (NWS) has issued flash flood warnings for parts of the greater Pittsburgh area in Pennsylvania until at least 23:00 Aug. 12. Areas under flash flood warnings include townships on the northeastern outskirts of the city, including Plum, New Kensington, and Burrell. Officials could update or amend the warning for the impact areas or surrounding regions in 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 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.
Localized business disruptions may occur in low-lying areas; some businesses might not operate at full capacity because of flood 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.
