The second storm, Typhoon Mangkhut, is big, and experts are warning that it has the potential to develop into a super typhoon.
Storm tracking platforms indicate Typhoon Mangkhut will pass slightly to the north of the Philippines on Saturday, September 15, before continuing west towards Guangdong province.
Although typhoon Mangkhut is possible to change course, the storm appears set to make landfall in or around the Pearl River Delta on either September 16 or 17.
As of 3pm yesterday, Mangkhut was releasing gusts of up to 185 kilometers per hour, according to an estimate published by the Philippine Star.
By Saturday morning, wind strength may reach 240 kilometers per hour near the eye of the storm.
