On August 19, the JTWC began monitoring a broad area of low pressure situated a couple hundred miles northeast of the Philippine archipelago. By the next day, the system rapidly organised, and the JTWC subsequently issued a Tropical Cyclone Formation Alert (TCFA), and on August 21, the area of low pressure organized into Tropical Depression 09W. [1] At 15:00 UTC, the PAGASA named the system "Igme" and issued a severe weather bulletin for it. [2] By the next day the system had intensified into a tropical storm, and the JMA gave it the name Bavi and upgraded it, with the JTWC doing the same. [3] Favorable conditions allowed Bavi to rapidly intensify, and by 12:00 UTC on August 22, the system became a severe tropical storm. The system left the Philippine Area of Responsibility on the same day. [4] Bavi's period of rapid intensification was brief, with its intensification significantly slowed on August 23.

On August 24, Bavi was upgraded into a typhoon by the JTWC as it continued to slowly intensify. Later on that day, it became a Category 2 typhoon, with it becoming a Category 3 typhoon on the next day. As Bavi moved closer to the Korean peninsula, one person died in Jeju Island on August 25. [5] Soon afterwards, as Bavi moved northwards into very hostile conditions and high wind shear, which caused Bavi to rapidly weaken. Wind shear was still high and the storm started extratropical transition. Around 00:30 UTC on August 27, a weakened Bavi made landfall over North Pyongan Province, North Korea as a minimal typhoon. [6] Both the JMA and the JTWC issued their final advisory on Bavi a few hours later as it became an extratropical cyclone over Northeastern China.

Preparations, impact, and aftermath

Japan

Bavi caused wind gusts of over 60 mph (97 km/h) and dropped 300 mm (12 in) of rain on the island of Okinawa. [7] Agricultural damage in Okinawa Prefecture was JP¥25.14 million (US$237 thousand). [8] Large waves associated with Bavi were reported as far away as Kagoshima Prefecture. [9]

South Korea

In South Korea, as a precaution over 470 flights were cancelled and railroad services were halted. Public parks were also closed for the typhoon. [10]

In Jeju Island, five people were swept away by strong waves, one of them died later. [11] Heavy rainfall was also reported in the island with a maximum amount of 399.5 mm (15.73 in) being reported near Mount Halla. [12] Despite a close pass to mainland South Korea, damage was minimal, consisting mostly of power outages, broken windows, and downed trees. Nevertheless, more than 100 reports of damage was submitted. The typhoon forced about 30 people in Gokseong, South Jeolla Province, to evacuate due to landslides. About 440 flights were cancelled at eleven airports across the country, while nearly 160 passenger ferries were grounded on 99 ferry routes. [13] Roughly 1,600 households in South Korea lost power. [14] Losses in Jeju reached ₩484 million (US$408 thousand). [15]

North Korea

North Korean leader Kim Jong-un held a high-level political conference where he voiced his concerns about Typhoon Bavi and the COVID-19 pandemic. [16] He ordered all levels of the Workers' Party to take steps to protect the country from the threat of the storm. [17]

Snapped utility poles and trees were reported near Bavi's landfall location, as well as flooded roads. A peak precipitation amount of 224 mm (8.8 in) was reported in Anju. [7] Several homes and public buildings were damaged in North and South Hwanghae provinces. [18]

In an unusual step, Korean Central Television remained on the air overnight on 27 August as the typhoon impacted the country, interrupting programs every 30 minutes with updates from the State Hydro-Meteorological Administration. It later broadcast images of storm damage, as well as field reports from correspondents in Pyongyang and Nampo—a major divergence from the strict format and content of all other KCTV news bulletins, where the activities of Kim Jong-un take precedence. No other coverage of the storm was included in KCTV bulletins until 28 August, when a story followed Kim as he inspected damage from the storm. [17] [19]

China

Several weather alerts were issued for portions of China as Typhoon Bavi neared. The Chinese Ministry of Emergency Management stated that 20,000 firefighters had been deployed equipped with 329 rescue boats.

In Northeast China, rounds of heavy downpours brought up to 150 mm (5.9 in) of rainfall in some areas. [20] Damage in Dalian amounted to be CN¥76.54 million (US$11.1 million). [21]

The 2020 Pacific typhoon season was the first with below-average tropical cyclone activity since 2017, with 23 named storms, 10 of which became typhoons and only 2 became super typhoons. This low activity was a consequence of La Niña that persisted from the summer of the year. It had the fifth-latest start in the basin on record, slightly behind 1973, and was the first to start that late since 2016. The first half of the season was unusually inactive, with only four systems, two named storms and one typhoon at the end of July. Additionally, the JTWC recorded no tropical cyclone development in the month of July, the first such occurrence since reliable records began. The season's first named tropical cyclone, Vongfong, developed on May 8, while the season's last named tropical cyclone, Krovanh, dissipated on December 24. However, the season's last system was an unnamed tropical depression which dissipated on December 29.

<span class="mw-page-title-main">Timeline of the 2015 Pacific typhoon season</span>

This timeline documents all of the events of the 2015 Pacific typhoon season. Most of the tropical cyclones formed between May and November. The scope of this article is limited to the Pacific Ocean, north of the equator between 100°E and the International Date Line. This area, called the Western Pacific basin, is the responsibility of the Japanese Meteorological Agency (JMA). They host and operate the Regional Specialized Meteorological Center (RSMC), located in Tokyo. The Japanese Meteorological Agency (JMA) is also responsible for assigning names to all tropical storms that are formed within the basin. However, any storm that enters or forms in the Philippine Area of Responsibility (PAR) will be named by the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) using a local name. Also of note - the Western Pacific basin is monitored by the United States' Joint Typhoon Warning Center (JTWC), which gives all Tropical depressions a number with a "W" suffix.

<span class="mw-page-title-main">Typhoon Chaba (2016)</span> Pacific typhoon in 2016

Typhoon Chaba, known in the Philippines as Super Typhoon Igme, was the fourth most intense tropical cyclone in 2016 and the strongest tropical cyclone to make landfall in South Korea since Sanba in 2012. Chaba also caused 7 deaths in the country. Typhoon Chaba was the eighteenth named storm and the eighth typhoon of the 2016 Pacific typhoon season.

<span class="mw-page-title-main">2022 Pacific typhoon season</span> Typhoon season in the Western Pacific Ocean

The 2022 Pacific typhoon season was the third consecutive season to have below-average tropical cyclone activity, with twenty-five named storms forming. Of the tropical storms, ten became typhoons, and three would intensify into super typhoons. The season saw a slightly below average activity by named storm count, although many of the storms were weak and short-lived, particularly towards the end of the season. This low activity was caused by an unusually strong La Niña that had persisted from 2020. The season's first named storm, Malakas, developed on April 6, while the last named storm, Pakhar, dissipated on December 12. The season's first typhoon, Malakas, reached typhoon status on April 12. The season ran throughout 2022, though most tropical cyclones typically develop between May and October. Tropical storms Megi and Nalgae were responsible for more than half of the casualties, while typhoons Hinnamnor and Nanmadol both caused $1 billion in damages.

<span class="mw-page-title-main">Typhoon Maysak (2020)</span> Pacific typhoon in 2020

Typhoon Maysak, known in the Philippines as Typhoon Julian, was a deadly, damaging and powerful tropical cyclone that struck the Ryukyu Islands and the Korean Peninsula in September 2020. The third typhoon of the 2020 Pacific typhoon season, Maysak formed from a tropical disturbance. The disturbance gradually organized, receiving the name Julian from PAGASA as it became a tropical depression. As the depression strengthened, the JMA subsequently named the system Maysak. Maysak rapidly intensified into a strong typhoon before weakening and making landfall in South Korea.

<span class="mw-page-title-main">Typhoon Haishen (2020)</span> Pacific typhoon in 2020

Typhoon Haishen, known in the Philippines as Super Typhoon Kristine, was a powerful tropical cyclone that became the first super typhoon of the 2020 Pacific typhoon season. Being also the tenth named storm and this season's fifth typhoon, Haishen's origins can be tracked back to a disorganised low pressure area situated near Guam. While the disturbance tracked south-westward and quickly organised, the JTWC issued a Tropical Cyclone Formation Alert (TCFA) on the system, and a day later, on September 1, the system became a tropical depression. The depression strengthened into Tropical Storm Haishen according to the Japan Meteorological Agency as it moved southwestward. At about 12:00 UTC on September 2, the Philippine Atmospheric, Geological and Astronomical Services Administration indicated that Haishen had entered the Philippine Area of Responsibility and was subsequently named Kristine. Later that day, Haishen became a typhoon. Intensification on September 3 was significant. Drifting northwestward into extremely favorable conditions, Haishen became a category 3-equivalent typhoon, acquiring a pinhole eye, before undergoing an eyewall replacement cycle (EWRC). Strengthening resumed soon after and the JTWC assessed wind speeds of 135 kn as it peaked as a powerful Category 4 super typhoon and had attained a new, symmetrical, clear eye.
