US: Flash flood warning in effect for parts of Kings, Queens, and Nassau counties, New York, until at least 01:15 EDT July 18

The US National Weather Service (NWS) issued a flash flood warning for parts of Kings, Queens, and Nassau counties, New York, including Brooklyn, Queens, and Valley Stream. The warning is in place through at least 01:15 EDT July 18.

Officials could update or amend the warnings 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 heavy rain has saturated the soil.

Localized transport and 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. Power outages and disruptions to telecommunication services are also possible.
