Puerto Rico: Flash flood warnings in effect for parts of territory until at least 17:00 Feb. 6

The US National Weather Service (NWS) has issued flash flood warnings for parts of Puerto Rico on Feb. 6. A flash flood warning is in effect for Carolina, Guaynabo, San Juan, and Trujillo Alto until at least 16:30; another flash flood warning is in effect for Caguas, Cayey, Cidra, and Gurabo until at least 17:00. Officials could amend the warnings for the impacted areas and/or extend them 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.
