US: Flash flood warning in effect for parts of Jefferson County, Texas until at least 17:30 CDT Oct. 31

The US National Weather Service (NWS) has issued a flash flood emergency for parts of Jefferson County, Texas until at least CDT 17:30 Oct. 31. The primary affected areas include Beaumont and Nederland. Officials could amend the warning for the impacted areas and/or extend it to the surrounding regions on short notice 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 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 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. Transport, electricity, and telecommunications disruptions are also possible in areas impacted by flooding.
