Cempaka is now overland, bringing total rainfall of 4 to 8 inches (100 to 200 millimeters) to parts of Guangdong, Guangxi and Hainan provinces. Isolated locations could approach 20 inches (500 millimeters) through Friday.
Typhoon In-fa has yet to directly make landfall, but it is gaining strength as it swirls westward over the Pacific Ocean.
Maximum sustained winds are 85 mph (140 km / h), as of Tuesday’s 5 p.m. ET (Wednesday 5 a.m. local time) update from the Joint Typhoon Warning Center.
The storm is starting to bring rain and tropical storm conditions to parts of the southern islands of Japan, and those chances of rain will remain high throughout this week as In-fa slowly moves west.
The slow nature of this storm will cause a substantial increase in total precipitation. Many islands in southern Japan will see totals of at least 10 inches (250 millimeters), with totals over 20 inches (500 millimeters) likely at higher elevations.
“In-Fa will pass south of Okinawa, closer to Miyakojima, which is built to handle the accompanying rains and wind. The problem can arise when the system moves near Taipei,” the meteorologist said. CNN, Tom Sater. Maximum winds near the center of In-fa are expected to approach 120 mph (195 km / h) in the area by Thursday evening, when the storm could reach its maximum intensity.
“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. . “
By Friday, In-fa is expected to approach Taiwan, which could have significant impacts on the country, especially the northern part of Taiwan, according to current forecasts.
It is not certain whether the typhoon will land in the country, but it should at least follow close enough for some impacts.
Flash floods from heavy rains will be of great concern, with totals of over 12 inches (300 millimeters) in the lower elevations and over 20 inches (500 millimeters) in the mountains of Taiwan later in the week.
Strong winds, which could cause power outages, will be another risk for these parts of East Asia. The Joint Typhoon Warning Center predicts that winds near the center of the storm will peak at 102 mph (165 km / h), with stronger gusts likely.
In-fa is expected to continue heading west, reaching eastern China this weekend. Current forecasts indicate that it will always be at the intensity of typhoons. Heavy rains will remain a threat from this storm throughout its duration.
