TYPHOON HINNAMNOR 2022
UPDATE 44 9.6.22 11AM
LOCATION 36.5°N 130.6°E
WINDS 80 MPH (129 KM/H)
GUSTS 95 MPH (151 KM/H)
PRESSURE 972 MB
MOVING AT 20 MPH (32 KM/H) NE
Category One Hurricane
Winds 74-95 mph (64-82 kt or 119-153 km/hr). Very dangerous winds will produce some damage: Well-constructed frame homes could have damage to roof, shingles, vinyl siding and gutters. Large branches of trees will snap and shallowly rooted trees may be toppled. Extensive damage to power lines and poles likely will result in power outages that could last a few to several days.
Hinnamnor (Philippine name Henry) is located 206 km northeast of Busan, South Korea, and has moved northeastward at 57 km/h (31 knots) over the past 6 hours.
Hinnamnor is embedded within a strong midlatitude shortwave trough with weak frontal structure, and has commenced extra-tropical transition. Infrared imagery shows asymmetric convection obscuring the low-level circulation center (LLCC) with the bulk of the deep convection shearing poleward due to strong southerly wind shear.
Microwave imagery shows the system has maintained a defined LLCC with limited curved banding. However, a delta rain region is evident over the northern quadrant.
Based on the defined LLCC, RJTD radar fix and an ASCAT ambiguity image, there is high confidence in the initial position. The initial intensity is assessed at 140 km/h (75 knots) primarily based on a radarsat2 SAR pass showing a swath of 130-145 km/h winds (70-78 knots) over the east and southeast quadrants.
Although not overly impressive, surface observations from Busan around 05/19:00 UTC-21:00 UTC, indicated maximum winds of 65 km/h (35 knots) gusting to 120 km/h (64 knots) and minimum sea-level pressure near 967 hPa, which corresponds to a 75 knot system.
Hinnamnor is forecast to rapidly transition into a strong extra-tropical, cold-core low in 12 hours as it gains frontal characteristics and approaches the midlatitude jet with very high wind shear (40-50 knots).
This is the final warning on this system by JTWC. The system will be closely monitored for signs of regeneration.

SUMMARY FOR SOUTH KOREA
SEOUL, South Korea — (AP) — Thousands of people were forced to evacuate in South Korea as Typhoon Hinnamnor made landfall in the country’s southern regions on Tuesday, unleashing fierce rains and winds that destroyed trees and roads, and left more than 20,000 homes without power.
A 25-year-old man went missing after falling into a rain swollen stream in the southern city of Ulsan, according to the Ministry of the Interior and Safety, which didn’t immediately report more casualties. Fires were reported at a major steel plant operated by POSCO in the southern city of Pohang, but it wasn’t immediately clear whether they were caused by the storm.
Government officials have put the nation on alert about potential damages from flooding, landslides and tidal waves unleashed by Hinnamnor, which they said would be the most powerful storm to hit the country in years. The storm came just weeks after capital Seoul and nearby regions were battered by heavy rainfall that unleashed flashfloods and killed at least 14 people.
Prime Minister Han Duk-soo had called for proactive efforts to evacuate residents in areas vulnerable to flooding, saying that Hinnamnor could end up being a “historically strong typhoon that we never experienced before.”
South Korea’s weather agency said Hinnamnor–packing heavy rains and winds of up to 144 kilometers (89 miles) per hour – was moving northeast toward open sea after grazing the southern resort island of Jeju and making landfall near the mainland port of Busan earlier on Tuesday (09.06.22).
The storm dumped more than 94 centimeters (37 inches) of rain in the central part of Jeju since Sunday, where winds once reached a maximum speed of 155 kph (96 mph).
The Safety Ministry said more than 3,400 people in the southern regions were forced to evacuate from their homes because of safety concerns and that officials were advising or ordering 14,000 more people to evacuate. At least five homes and buildings were flooded or destroyed, and scores of roads were damaged.
More than 600 schools nationwide were closed or converted to online classes. More than 250 flights and 70 ferry services were grounded, while more than 66,000 fishing boats evacuated to ports. Workers as of 6 a.m. managed to restore electricity to 2,795 of the 20,334 households that were knocked out of power.
