According to the Joint Typhoon Warning Center (JTWC), at 17:00 ET (21:00 UTC) on September 16, the maximum sustained wind speed in Nanmadol reached 155 mph (249.5 km/h) with gusts up to 190 miles per hour (306 km/h). This makes it a severe Category 4 storm on the Saffir-Simpson Hurricane Scale. At the time, the super typhoon was about 379 miles (610 km) east of Kadena Air Base, Okinawa, Japan, and was moving northwest. The maximum significant wave height was estimated at 52 feet.

Hundreds of thousands of people were called to evacuate as Typhoon Nanmadol is expected to hit Kyushu on Sunday.
Kyushu, the southernmost of the four islands that make up the bulk of Japan, is under a “special alert” with landslide and flood warnings. Trains and flights have been cancelled.
The Joint Typhoon Warning Center, the US military command in Hawaii, also issued a storm warning, calling Nanmadol a “super typhoon” this week.
NHK World, which collects warnings issued by local authorities, said level four evacuation instructions – the second largest – have been put in place for people in Kagoshima, Kumamoto and Miyazaki in the southern region of Kyushu.
Besides, according to The GuardianThe Japan Meteorological Agency has declared the highest level of danger for the Kagoshima region. This is the first special typhoon warning issued outside of Okinawa since the current system was launched in 2013.
It is reported by the BBC. that on Saturday the typhoon was close to the remote island of Minami Daito, 400 km (250 miles) east of Okinawa, and is expected to approach or make landfall on Sunday in southern Kagoshima Prefecture in Kyushu, and then move north to the next day. his strength – before heading towards the main Japanese island.
“There are risks of unprecedented storms, high waves, storm surges and record rainfall,” said Ryuta Kurora, head of forecasting at the Japan Meteorological Agency.
“Ultimate caution is required,” he said, urging people to evacuate early. “This is a very dangerous typhoon. The wind will be so strong that some houses may collapse,” Kurora added, warning that floods and landslides could also occur.
Let’s make sure everyone agrees when it comes to storm terminology. The terms typhoon, hurricane, and cyclone refer to tropical cyclones; and the term that applies to this storm depends on where it happens.
Typhoons develop in the Pacific Northwest and usually hit Asia. Hurricanes form in the North Atlantic, the Pacific Northeast, the Caribbean, and the Gulf of Mexico.
in the Atlantic strong hurricanes defined as tropical cyclones with maximum sustained winds of 111 mph or higher and are classified as Category 3, 4, or 5 storms. But across the Asia-Pacific region, there are differences in how individual countries rate typhoons.
Finally, in meteorology, a cyclone is a large mass of air that orbits around a strong center of low atmospheric pressure. Cyclones rotate counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere when viewed from above, according to BBC.
