CAGUAS, Puerto Rico — A growing number of businesses, including grocery stores and gas stations, are temporarily closing across Puerto Rico as power outages caused by Hurricane Fiona drag on in the U.S. territory, sparking concern about the availability of fuel and basic goods.

Hand-written signs warning of closures have been popping up more frequently, eliciting sighs and groans from customers on an island where 62% of 1.47 million clients still do not have power more than four days after the storm hit.
