A weakening In-fa is beginning to track away from the southern Japanese islands but has its eye set on eastern China by the end of this weekend. The storm could bring extremely heavy rainfall to millions in China.
And behind In-fa, there is a growing tropical threat from newly named Tropical Storm Nepartak for northern and central parts of Japan, which could potentially impact the Olympic Games by early next week.
In-fa is currently located about 275 kilometers (170 miles) west-southwest from Okinawa and is moving northwest. The storm has been a typhoon for much of this week but has now weakened to a strong tropical storm, with winds up to 110 kph (70 mph) near its center, as of the 5 p.m. ET update from the Joint Typhoon Warning Center.
In-fa has been weakening due to dry air, thus weakening its thunderstorms, as well as slightly cooler sea surface temperatures.
The good news…
