Puerto Rico: Flash flood warning in effect for parts of several municipalities until at least 17:45 Sept. 10

Flash flood warning in effect for Bayamon, Guaynabo, and San Juan municipalities, Puerto Rico, until 17:45 Sept. 10. Disruptions possible.

Warning

The US National Weather Service (NWS) issued a flash flood warning for parts of Puerto Rico's Bayamon, Carolina, and San Juan municipalities on Sept. 10. The warning is in effect until at least 17:45. 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 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. Transport, electricity, and telecommunications disruptions are also possible in areas impacted by flooding.

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.
