In-fa is currently located approximately 275 kilometers (170 miles) west-southwest of Okinawa and moves northwest. The storm has been a typhoon for much of this week, but has now weakened into a strong tropical storm, with winds reaching 110 km / h (70 mph) near its center, as of the update 5 p.m. ET from the Joint Typhoon Warning Center.
In-fa was weakening due to dry air, thus weakening its thunderstorms, as well as slightly cooler sea surface temperatures.
The good news is that no significant strengthening of this storm is expected for this reason. But it will always be a strong tropical storm or a weak hurricane that will hit the lands of the Northwest Pacific Ocean.
In-fa will head to eastern China
In-fa is starting to move away north and west of the Japanese islands, but rain and wind will persist until Saturday.
The center of the storm is now passing well north of Taiwan, but the island will still receive significant amounts of rain.
“Taiwan’s mountain range could send up to a meter of rain over the region, while Taiwan faces its worst drought in about 50 years. This amount of rain could lead to flash floods and catastrophic landslides. “said the CNN meteorologist. Tom Sater.

As In-fa moves away from Japan and Taiwan over the weekend, the storm will move towards eastern China and likely affect the region from Sunday.
It is expected to make landfall in the area between Shanghai and Wenzhou, bringing strong winds and heavy rain.
The Typhoon Warning Center expects maximum sustained winds near the storm center to be around 60 mph (95 km / h), which is a strong tropical storm. However, the storm may still be typhoon-like due to some still uncertain in the forecast.
The biggest concern is possible flood rains for heavily populated areas of China.
“Heavy rain will be history with this on the Shanghai side of the storm and where most of the moisture is pushed onto the shore,” CNN meteorologist Michael Guy said.
“Precipitation up to 10 inches (250 millimeters) will be widespread with higher amounts up to 20+ inches (500+ millimeters) in isolated locations. Flooding will be a major concern because of this.”
Nepartak may affect the Olympics
