Tropical Storm Vongfong Slamming Japan

While Japan is recovering from former Typhoon Phanfone, another storm is slamming the country.
Vongfong, meaning "the wasp" in Cantonese, has turned northeastward and will move across Kyushu and Shikoku Monday, local time, before accelerating across Honshu Monday night and emerging out into the northern West Pacific on Tuesday. The center of the storm, once classified as a super typhoon, passed across the island of Okinawa very late Saturday night into early Sunday morning, local time.
This dangerous storm has already recorded a brutal history. Vongfong, as a typhoon, brought flooding rainfall and damaging wind to the northern Mariana Islands on last Sunday, local time. Wind gusts over 89 kph (55 mph) and rainfall over 75 millimeters (3 inches) were common.

Vongfong was classified as a super typhoon during the middle of last week as it moved through an area of low wind shear and very warm ocean temperatures but has since lost that title. The tropical system had reached the equivalent strength of a Category 5 hurricane, featuring wind speeds greater than 257 kph (160 mph).

"Vongfong became the strongest tropical cyclone we've had all year anywhere on Earth," AccuWeather.com Meteorologist Jim Andrews said.
The strength of Vongfong earlier surpassed that of Super Typhoon Genevieve which, at its most powerful, had sustained winds of 257 kph (160 mph) in the West Pacific.
A good amount of weakening has brought the strength of Vongfong down to the equivalent of a tropical storm. However, Vongfong still threatens dangerous and life-threatening conditions.

The potent storm will bring life-threatening conditions to many over the course of the first couple of days of the new week. "Destructive winds and flooding rain will be the top threats," Andrews said.
Vongfong blasted through the Ryukyu Islands of southern Japan over the weekend. Wind speeds peaked at 143 kph (89 mph) at the Kadena Air Base in Okinawa. Nearby, about 500 mm (20 inches) fell at Kunigami on Saturday.
Fierce winds brought power outages across the island. Conditions will gradually improve through Sunday as Vongfong pulls away to the north.
The Japanese media outlet NHK reports that strong winds caused injuries to 40 residents in Okinawa, Kagoshima and Miyazaki prefectures with some suffering serious injuries. As of 11 a.m. JST Sunday, more than 110,000 combined blackouts were reported in the Okinawa and Kagoshima prefectures.

After battering the Ryukyu Islands, the focus is now shifting to mainland Japan. The worst impacts across mainland Japan are expected through early Tuesday as near typhoon-force wind gusts and inundating rainfall spread from southwest to northeast across the nation.
The storm made landfall on the island of Kyushu near Kagoshima around 9:15 a.m. Monday, local time, as the storm begins to accelerate northeastward.
A continued weakening of Vongfong is expected as the tropical storm approaches and moves across mainland Japan; however, the storm will still bring life-threatening conditions to most of Japan with the greatest impacts expected in Kyushu, Shikoku and southern Honshu. there flooding rainfall will combine with damaging wind gusts.
Rainfall in much of Japan will surpass 125 mm (5 inches) from Sunday to Tuesday with much of Kyushu, Shikoku and southern Honshu seeing in excess of 250 mm (10 inches). AccuWeather.com meteorologists warn that over 500 mm (20 inches) could fall in some of the mountainous terrain which will not only lead to flooding, but the risk for mudslides as well.

Many areas at risk from Vongfong are still recovering from more than 150 millimeters (6 inches) of rain and strong winds that hammered eastern Japan barely a week ago as Typhoon Phanfone moved through the region.
Tokyo was deluged by 272 millimeters (10.71 inches) of rain ahead of and during the height of Phanfone.
"Phanfone was a huge rainstorm for Tokyo, one of the biggest I can remember," Andrews added, noting moisture from the storm interacted with a stalled front, prolonging the duration of rain.
There could be another round of flooding rainfall in Tokyo Monday and Monday night with up to 150 (6 inches) of rain expected in some places.
"The threats are the same as they were with Phanfone," Andrews said. "There are some likenesses but also some differences in Phanfone's track. The results can vary markedly with small differences in track and storm speed."
