Tropical Storm NARI (0711) in WPAC

[CherlynV]

Koreans might want to start making preparations.

Definitely - flooding/storm surge is a huge issue up there.

[P.K.]

Down to 90kts with the centre pressure up to 945hPa.

Looks like South Korea has to prepare for Nari. Almost the whole cone is in Korea. This could be a problem for them. I have relatives in South Korea. Hopefully, they are aware of Nari coming towards them. Korea is mountainous, which causes heavier rain and flooding. Typhoon Rusa in 2002 hit Korea and dumped up to 36 inches of rain in the mountains.

[Chacor]

One positive is it should already be undergoing extratropical transition when the storm starts to cross Korea, meaning less centralised winds. Also, it's forecast to weaken quite quickly.

Reports of 200mm of rain already fallen on Cheju (Jeju) Island. Portions of South Korea are forecasted to receive at an additional 300mm of rain.

[P.K.]

Jeju Island now reporting a daily precipitation total of 420.0mm.

There were radar echoes exceeding 35mm/h in places as the centre passed over Jeju Island. However there were echoes of this intensity over the island at least six hours before this.



The latest image shows a max of about 20mm/h.

Sadly deaths have been reported in South Korea.

Typhoon leaves 14 dead or missing

Typhoon Nari lashed the southwestern part of the nation late yesterday, bringing torrential downpours and strong winds that left at least 14 people dead or missing, and scores of others injured.

The 11th typhoon of the year slammed into the port city of Yeosu at 6:15 p.m., hours earlier than previously expected, felling trees and smashing windows as it packed winds of up to 97 kilometers per hour.

Jeju Island was hit hardest, as over 500 millimeters of rain fell during the day, with a maximum wind speed exceeding 50 meters per second.

As of 8:30 p.m. yesterday, the Korea Meteorological Administration has issued a typhoon alert for most parts of the nation, except for Seoul and Gyeonggi Province.

The small but strong typhoon, named after the Korean word for lily, had 980 hectopascals of atmospheric pressure, and a maximum wind speed of 27 meters per second at its center.

It was moving northeast from Yeosu at a speed of 25 kilometers per hour, according to the weather agency.

The KMA forecast that Typhoon Nari would sweep over to the East Sea before noon today.

On Jeju, at lease five people were found dead and two went missing as the record-breaking rainfall inundated four major rivers running across the island.

Thousands of residents in low-lying areas were evacuated as hundreds of buildings and houses went underwater.

Television footage showed piled-up cars and broken-down roads half sunk in muddy water.

The tropical storm also cut power to nearly 50,000 households on the island. Restoration was delayed due to the bad weather.

Tens of thousands of passengers were stranded on the island, as most flights were cancelled and ships were moored at ports. Some 11 vessels sank or went aground due to the strong winds and high waves.

In the southern cities of Yeosu and Gwangju and surrounding South Jeolla Province, the typhoon left at least seven people dead or missing as it made a short but powerful landfall.

A ship was turned upside down in surging waves off the coast of Mokpo at around 3:40 p.m., leaving two sailors missing and one dead.

Minor injuries were reported as winds shattered glass in high-rise apartment buildings.

Power transmission facilities were also damaged by heavy rains accompanying the gusty winds, causing hours-long blackouts at tens of thousands of households in the region.

In the meantime, the 12th typhoon of the year was located some 800 kilometers southeast of Okinawa early yesterday.

The weather agency said it is yet to be seen whether Typhoon Wipha would have an impact on Korea. As of 9 a.m. yesterday, it was a small-sized storm with 992 hectopascals of atmospheric pressure at its center and a radius of about 200 kilometers.

Looks like that's it. Since there's aftermath I'll leave this open for a little longer.

I wonder why Sogwipo Observation has 29 knots and 973.1 mb. Wouldn't 973 mb have higher winds than that? I guess the weather station lost power. 16 inches of rain is a lot for sure. Looks like South Korea is in it for heavy rain.

Maybe it was near the centre (or what was left of the centre) of the storm at that very time, hence lower winds.
