Simpaka now extends 4 to 8 inches (100 to 200 millimeters) of total rainfall over parts of Guangdong, Guangzhou and Hainan provinces, over land. Isolated locations can go 20 inches (500 millimeters) by Friday.
Typhoon In-F has not yet hit any land directly, but it is gaining strength as it travels west over the Pacific Ocean.
The maximum sustained wind speed is 85 miles per hour (140 kilometers) as of Tuesday evening at 5pm ET (Wednesday local time am am am) update of the Joint Typhoon Warning Center.
The storm has begun to bring rain and tropical storm conditions to parts of the southern islands of Japan, and the chances of this rain will improve during this week’s period as In-Fa slowly tracks westward.
Due to the slow-moving nature of this storm, the amount of rainfall will increase considerably. Many islands in the south will see a total of at least 10 inches (250 millimeters), with higher elevations likely to be more than 20 inches (500 millimeters).
CNN meteorologist Tom Sutter said, “In-Fa will be near Miyakozima, south of Okinawa, which was built to adjust to rain and wind. This problem could occur as soon as the system runs near Taipei.” The wind is expected to blow at 120 mph in the region until midnight on Thursday, with maximum winds near the center of the inf, when the storm could reach maximum intensity.
“Taiwan’s mountain range could exceed one meter of valuable rainfall in the region. Taiwan is facing its worst drought in nearly 50 years. This amount of rainfall could cause catastrophic floods and landslides.”
By Friday, In-Fa is likely to be closer to Taiwan, probably according to the current forecast track, especially the northern part of Taiwan will have a significant impact on the country.
It is unknown at this time what he will do after leaving the country.
Flash floods with heavy rainfall will be a major concern, with a total of 12 inches (300 millimeters) at low altitudes and more than 20 inches (500 millimeters) in the mountains of Taiwan over the weekend.
Strong winds, which could cause power outages, could be even more risky for these regions of East Asia. The Joint Typhoon Warning Center is forecasting winds of about 102 miles (165 kilometers) from the epicenter of the storm, with higher risk.
In-FA is expected to continue tracking west, arriving in eastern China this weekend. The current forecast indicates that it will still be at the intensity of the typhoon. Heavy rainfall will remain as a threat from this storm through its duration.
East China record rainfall before In-FA
Heavy rains in the Chinese city of Zhengzhou broke a record on Tuesday, the city’s weather bureau said Tuesday.
At least one person has been killed and two others are missing in floods in the Chinese city of Gangi in Henan province, state media CGTN reported on Tuesday.
“Since the establishment of the Zhengzhou Meteorological Bureau in 1951, the hour-long historical record of hourly and single-day rainfall has been broken,” the Zhengzhou Meteorological Department said in a video posted explaining the rainfall.
“The rainfall in the city over the last three days was already the same as the rainfall in the city last year,” the department said.
According to the bureau, the average annual rainfall in Zhengzhou is 25/2 inches (640.8 mm). Meanwhile, according to their analysis of recent rainfall, the city received 9.9 inches (2012.9 mm) of rain from 4pm to 5pm on Tuesday. The city received 21.8 inches (552.5 millimeters) of rain from 8 a.m. Monday to 8 p.m. Tuesday; And the city received 24.3 inches (617.1 millimeters) of rain from 8pm on Saturday to 8pm on Tuesday.
The humidity associated with this rain can be linked to both Typhoons Simpaka and In-Fa, despite being a few miles away from this part of China.
China’s state-run Xinhua news agency said on Tuesday that torrential rains had hit central China’s Henan province since Friday, affecting more than 144 residents. More than 10,000 people have been evacuated.
The highest level of rainfall in Pingdingshan City, Lushan County, was 15.8 inches (400.8 millimeters), Xinhua reported, with rainwater damaging 3535 square miles (9,000 hectares) of crops, resulting in losses of .3 11.3 million.
