# Typhoon Saola (2023)

Typhoon Saola, known in the Philippines as Super Typhoon Goring, was a powerful and erratic tropical cyclone that affected the Philippines, southern Taiwan, Hong Kong, Macau and South China in late August 2023. The name Saola, is in reference to a rare animal found in Vietnam. The ninth named storm, seventh typhoon, and third super typhoon of the 2023 typhoon season, Saola originated from an area of convection east of Taiwan and headed southwestwards.
Saola then began a process of rapid intensification while making a looping trend. Although it did not make a direct landfall over Luzon, Saola made the closer pass into Central Luzon as a Category 4 equivalent typhoon, bringing gusty winds and heavy rains over the country. It weakened back to a Category 2 typhoon on September 1. After it executed a south-southeastward turn, Saola went again in an explosive intensification to Category 5 as it passes over Batanes and left PAR on August 31 still as a super typhoon.
Prior to the approach of Saola, HKO raised the highest signal category in anticipation of the storm, the first time in 5 years since Mangkhut of 2018. The storm continued to approach closely over Hong Kong and Macau, battering with strong gusty winds and heavy rains over the area before weakening and making landfall over Southern China.

## Meteorological history

On August 20, an area of convection east of Taiwan began moving southwestwards with little organization over its center. The PAGASA marked the system as a low-pressure area on August 22, and the Japan Meteorological Agency upgraded it to a tropical depression. The PAGASA initially expected the system to not develop into a tropical cyclone, but later upgraded it into a tropical depression the next day, and was given the local name of Goring, it was also given a Tropical Cyclone Formation Alert by the JTWC, designated as Tropical Depression 09W. Goring then moved generally north-northwestwards across the Philippine Sea. On August 24, Goring was upgraded to a tropical storm by the JTWC, with the JMA following suit a few hours later at 06:00 UTC, receiving the name Saola. PAGASA also followed suit in upgrading the system into a tropical storm in their 17:00 PHT (09:00 UTC) update. Saola continued to intensify and began to move southwestwards over the Philippine Sea east of the Batanes Islands. PAGASA then started to issue Tropical Cyclone Wind Signals across the eastern parts of Northern Luzon on Friday morning. A few hours later, the JTWC upgraded Saola into a typhoon, with the JMA upgrading the system to a severe tropical storm shortly thereafter. Saola was then later upgraded into a typhoon moments later by the JMA, with JTWC upgrading it to a Category 2, beginning a process of rapid intensification. PAGASA followed suit by the evening and upgraded Saola into a typhoon as well. Saola was then upgraded to a Category 4 typhoon by the morning of August 27 with an initial peak intensities of 120 kts by the JTWC, 95 kts and minimum pressure was 940 mbar by JMA.
In the early morning hours of Sunday, PAGASA then upgraded Goring (Saola) into a super typhoon after its winds passed 185 km/h (115 mph), becoming the third storm to enter in their 'super typhoon' category this year. Saola then had some fluctuations in intensity between category 3 and category 4 due to interactions with mountainous terrain and upwelling cold water due to slow movement despite highly favorable environmental conditions. Saola then executed a south-southeastward turn over the Philippine Sea, begin the eyewall replacement cycle and then weakened back into a typhoon per PAGASA, with Tropical Cyclone Wind Signal #2 and #3 being lifted as it moved away from Central Luzon. The Joint Typhoon Warning Center also downgraded Saola into Category 2 typhoon, and PAGASA dropped some tropical cyclone wind signals in Eastern Luzon. It then turned northwest, and PAGASA reissued Signal 4 for parts of the Babuyan Islands and then explosively intensified into a Category 5 super typhoon, per the Joint Typhoon Warning Center. PAGASA then followed suit and upgraded Saola (Goring) into a super typhoon once more as it was passing between the Bashi Channel, and issued Signal #5 in the northeastern portion of the Babuyan Islands, the second time this year since Typhoon Doksuri a month earlier. Later that day, Saola crossed the northwestern boundaries of the Philippine Area of Responsibility, and PAGASA issued their final tropical cyclone advisories on it, with storm signals being dropped moments later. Saola remained a powerful super typhoon as it crossed into the South China Sea southwest of Taiwan, featuring a clear and warm eye as it did so. On the afternoon of August 31 (UTC), the JTWC noted that Saola was struggling to complete an eyewall replacement cycle, resulting in some slight weakening.
However, Saola held onto Super Typhoon Status on the JTWC scale. Meanwhile, Saola fell below the threshold for Violent Typhoon on the JMA scale that same afternoon. Around the same time, the Hong Kong Observatory had announced that tropical cyclone warning signal number 8 (Tropical Storm) would be issued at 2:40 a.m local time on Friday, with the potential of this being raised to warning signal number 10 (Hurricane) as Super Typhoon Saola drew closer. It was warned that at some locations storm surges due to Super Typhoon Saola could reach historic levels, rivaling those of Typhoon Wanda in 1962 and Typhoon Hato in 2017. This has since been upgraded at 6:20pm to an increasing gale or storm signal number 9, and later to the Hurricane Signal number 10 at 8:15pm, becoming the first time in 5 years that the highest warning signal was raised since Typhoon Mangkhut (Ompong) back in 2018. Saola continued approaching near Southern China including Hong Kong with maintaining intensify Category 4 super typhoon. Saola then passed south of Hong Kong and Macau with another fluctuation between Category 3 and 4 before made landfall in Guangdong, China on early Saturday as a Category 3. After its landfall, Saola weakened into a strong Category 2 typhoon. The Japan Meteorological Agency then downgraded Saola into a severe tropical storm a few hours after landfall. The JTWC later followed suit and downgraded Saola into a tropical storm by their next update as it moved further inland Guangdong. As convection waned over its center, the agencies downgraded the once-powerful Saola into a tropical depression by September 2. Saola had dissipated on September 3, with its remnants causing rainfall and stormy conditions across Southern China.

## Preparations
### Philippines

Upon Saola's (known locally as Super Typhoon Goring) designation as a tropical storm on August 24, PAGASA has issued Tropical Cyclone Wind Signal No. 1 for the northeastern part of Cagayan. After the storm reached typhoon status on the morning of August 25, the agency raised Signal No. 2 for parts of northern Luzon and Signal No. 3 in the eastern portions of Isabela as Saola made its closest approach to mainland Luzon which was then removed as Saola made a counter-clockwise loop across the Philippine Sea. Telecommunications company Globe Telecom prepared emergency supplies and personnel in areas that may be affected by the storm. Classes were suspended on August 29, the first day of the school year, in areas that had been impacted by typhoons. As a preventative measure for Saola's impacts, the Philippine Coast Guard (PCG) ordered the temporary suspension of all sea traffic for all types of vessels. About 25,000 people evacuated. After the storm reached super typhoon status on the morning of August 29, the agency raised Signal No. 5, its highest warning signal—under the risk of violent, life-threatening winds—for the Babuyan Islands for the second time this year after Super Typhoon Doksuri. Local flights were suspended early the next day as the storm wreaked havoc on Northern Luzon. Flooding in four Cagayan towns forced the evacuation of 388 individuals, and floods rose in two other towns. By August 30, most TCWS signals were lowered by the PAGASA as the storm left the Philippine Area of Responsibility.

### China

The China Meteorological Administration (CMA) issued a red typhoon warning; heavy rainfall is anticipated across the provinces of Guangdong and Guangxi, as well as Hong Kong and Macau; the heaviest rainfall of 10–18 cm (3.9–7.1 in) is likely in the southwest of Guangdong Province.

### Hong Kong

A T8 warning signal, landslide and rain alerts, and a special notice on floods in the northern New Territories have all been issued by the Hong Kong Observatory. This has since been upgraded to an Increasing Storm Signal No. 9 and later to Hurricane Signal No. 10, the highest level of tropical cyclone warning signals in Hong Kong, at 8:15 p.m, becoming the first time in 5 years that the highest warning signal has been raised since Typhoon Mangkhut back in 2018.

### Taiwan

The Central Weather Bureau (CWB) issued a sea warning on August 28. As Saola continued to approach the island, the CWB issued a land warning to the southern part of Taiwan early on the next day, locally. The CWB lifted the land warning late on August 31. Some operators decided to suspended eight domestic flights and 72 ferry services. School and work were canceled in the parts of Kaohsiung and Pingtung County.

## Impact
### Philippines

Typhoon Saola and Haikui carried expansive rain bands as it approached the Philippines, exacerbating the existing southwest monsoon and causing widespread rains and floods over most of the country. Saola brought torrential rains to parts of Metro Manila. Two fatalities were confirmed in the Philippines, another went missing and three were injured. Almost 1,086,837 people were affected by Saola. At least 7,813 houses were affected, including 334 which were destroyed. Damage from the storm amounted to ₱2.49 billion (US$43.9 million).
Saola was initially expected to strike into Taiwan, but instead went into the Bashi Channel between the Babuyan Islands and Batanes, bringing strong winds and heavy rainfall across the area.

### South China

On the coastal islands of Guangdong, sustained winds were recorded at 118 mph (190 km/h) at Guishan Island, and gusts were recorded at 139 mph (224 km/h) at Miaowan Island. In Guangdong Province, trees and building signs were blown off by the storm, and one person died in Shenzhen after a tree fell and hit their vehicle. Total damages were about ¥930 million (US$128.4 million).

### Hong Kong

At least 86 people were injured due to storm-related effects, two landslides occurred and 1,545 trees were downed in Hong Kong. Estimated damages were about HK$3.92 billion (US$500 million).

## Retirement

On January 19, 2024, PAGASA announced that the name Goring was retired from the rotating naming lists due to the damages it caused throughout its onslaught despite not making landfall in the Philippines and it will never be used again as a typhoon name within the Philippine Area of Responsibility (PAR). It will be replaced with Gavino for the 2027 season.
After the season, the Typhoon Committee announced that the name Saola, along with two others, will be removed from the naming lists. In the spring of 2025, the name was replaced with Saobien, a common name for echinoderms of the class Asteroidea (starfish).
