US: Flash flood warning in effect for parts of East Baton Rouge Parish, La., until at least 20:00 CST Dec. 9

The US National Weather Service (NWS) has issued a flash flood warning for parts of East Baton Rouge Parish in southern Louisiana until at least 20:00 CST on Dec. 9. Affected areas include Baker, Central, the city of Baton Rouge, La. 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 heavy rain saturates the soil.

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.
