Coast Guard aerial assets have been deployed to monitor an oil spill with “an estimated coverage of two nautical miles (2.3 miles) carried by a strong current,” it said. On land, the flooding has caused widespread disruption that forced authorities to close schools, businesses and cancel more than 150 flights on Thursday. Carlito Pagaduan, a resident of northern Ilocos Sur province, told CNN that heavy rains descended early Thursday and although floodwaters had not entered his home he feared they may lose power in the hard-to-reach area. “We’re trying to save battery,” he told CNN. “Due to strong winds, we don’t know when we’ll lose electricity.” He said his family has prepared for evacuation but will stay in their home for now.Rescue services said Thursday they are continuing to pull trapped residents out of flooded buildings. Some homes could be seen completely inundated and vehicles submerged on flooded streets.
