Typhoon Narra's Five-Day Gulf Loop Triggers Floods in Southern China
Typhoon Narra, the 19th named storm of 2026, stalled over the Gulf of Tonkin for about five days after forming over the northern South China Sea. Its slow, looping track, at times moving at only 3–5 km/h, prolonged heavy rain across northern Vietnam and southern China. Flooding inundated homes, triggered landslides and forced 54,000 people to relocate in Guangxi by August 23, while northern Vietnam later reported three deaths and three injuries linked to the storm and its associated flooding. Narra made four landfalls between August 20 and August 26 before weakening into a low-pressure area over western Guangdong.

From Tropical Depression to Named Storm: Narra's Birth Over the South China Sea
Narra did not begin as a conventional coastal typhoon approaching Vietnam. A tropical depression formed over the northern South China Sea on the afternoon of August 19, then reached the coast of Wenchang, Hainan, at about 5:40 a.m. on August 20 while still a tropical depression. After crossing Hainan Island, the system entered the Gulf of Tonkin and later strengthened into Typhoon Narra on the afternoon of August 21.

That early landfall is important because it explains why Narra ultimately recorded four separate landfalls rather than two. The first came at Wenchang on August 20. The second occurred at Changjiang, Hainan, at about 6:40 p.m. on August 25, when the storm carried maximum sustained winds of 20 m/s near its center. The third came at Xuwen County in Guangdong at about 3:25 a.m. on August 26, with winds near 18 m/s. The fourth followed at about 11 a.m. near Wuchuan, Guangdong, after Narra had weakened further.

Narra strengthened gradually and never became a major typhoon. Its strongest monitored phase occurred while it was over the Gulf of Tonkin, with maximum sustained winds around 83 km/h in the consolidated track record. Even at that intensity, the storm retained enough circulation to generate strong winds over exposed waters, rough seas and repeated bands of heavy rain.

The storm's international name also has a Philippine connection. Narra was one of the names contributed by the Philippines to the regional tropical-cyclone naming list used by the Japan Meteorological Agency. PAGASA maintains a separate domestic naming system for cyclones that enter or develop within the Philippine Area of Responsibility, but Narra never entered that area, so PAGASA did not assign it a separate local name or issue Philippine Tropical Cyclone Wind Signals No. 1–5 for Narra.
That distinction matters in regional reporting. The international name Narra belongs to the Western North Pacific naming system, while PAGASA's local names and signal system apply to storms affecting its own warning area. Narra remained north and west of the Philippines as it developed, crossed Hainan and then became a prolonged Gulf of Tonkin system.
Five Days, One Knot-Like Path: Why Narra Stalled Over the Gulf
Narra's most unusual feature was its movement after reaching the Gulf of Tonkin. Instead of making a quick landfall or moving steadily away, the storm slowed to roughly 3–5 km/h and repeatedly changed direction. It moved north, then west and southward, later turned back toward the east and northeast, tracing a compact, irregular path over the gulf.
VietNamNet
Vietnamese forecasters linked the behavior to weak and competing steering influences around the storm. Narra developed within the Intertropical Convergence Zone, while the broader atmospheric flow did not provide a strong, stable direction of travel. Changes in surrounding weather systems and the storm's own circulation then helped produce the repeated turns.
Most tropical cyclones entering the Gulf of Tonkin move across the relatively confined basin within a day or two. Some remain there for only several hours before weakening or making landfall. Narra maintained its storm circulation over the gulf for five to six days, an unusually long residence time for the region. Historical comparisons cited by Vietnamese forecasters include Typhoon Amy in July 1994, which remained over the Gulf of Tonkin for four days.
Vietnam News
The slow motion had a direct effect on rainfall. A moving storm shifts its heavy-rain area from one location to another, but Narra repeatedly exposed the same parts of northern Vietnam and southern China to moisture-laden bands. Rainfall accumulated over already saturated ground, rivers continued to rise and mountain slopes became increasingly unstable.
Northern Vietnam felt the effects before Narra's final Chinese landfalls. Rainfall from August 21 into August 23 reached 150–250 mm in parts of Quang Ninh, Lang Son and Hai Phong, with some stations recording more than 300 mm. Authorities restricted maritime activity in exposed coastal areas, while residents in flood- and landslide-prone locations faced prolonged rainfall rather than a short period of severe weather.

By August 26, the human toll had increased. Initial reports recorded two deaths and three injuries in northern Vietnam; an additional lightning-related death reported on August 27 brought the storm-related death toll to three, while the number of injured remained three. Thousands of homes were flooded or damaged, and large areas of rice and other crops were affected.

Narra's slow movement, not its wind speed, drove the flooding.
Guangxi's Flood Crisis: 54,000 Relocated as Rivers Swell
Guangxi became the most severe flood-impact zone in southern China while Narra remained over the Gulf of Tonkin. Heavy rain pushed rivers above warning levels, flooded low-lying communities and cut roads and local infrastructure. In Chongzuo, floodwater rose high enough to force large-scale evacuations, with more than 15,000 residents relocated from areas threatened by rising rivers.
The key Guangxi figures require a clear time stamp. As of 6 p.m. on August 23, official regional figures recorded 61,000 people affected by the storm, 54,000 people transferred from danger areas and 8,087 people placed in emergency accommodation. At the same time, heavy to torrential rain had affected dozens of towns and multiple river monitoring stations had recorded water levels above warning thresholds.
China News
The numbers later used in international reporting—54,000 people relocated across Guangxi—therefore describe the evacuation figure, not the total number of people affected. The distinction is important: 61,000 people were reported affected, while 54,000 were moved because of the flooding, including 8,087 placed in emergency shelters at that reporting point.
The hydrological response was already visible in the river network. Ten rivers and 15 monitoring stations had exceeded warning levels by the evening of August 23, including sections of the Ming River system and the Zuo River basin. In parts of Chongzuo and neighboring areas, floodwater covered roads and entered buildings, forcing rescuers to use boats to reach stranded residents.
China News
Rainfall totals in the wider Guangxi region also showed why the flooding continued after the storm center had moved. Persistent rain over several days allowed runoff from hills and upstream catchments to arrive after the initial downpours. In a region marked by karst terrain, narrow valleys and fast-responding rivers, repeated heavy rainfall can quickly turn localized flooding into a broader river emergency.
Narra also disrupted normal activity farther along China's southern coast. Heavy rain affected Hainan and Guangdong, while authorities suspended some tourism and maritime operations and kept residents away from flood-prone areas. The storm's effects were compounded by another active tropical cyclone elsewhere in the western Pacific, although the flooding in Guangxi was directly associated with Narra's prolonged rainfall.
The sequence in Guangxi was therefore straightforward: Narra stalled offshore, rain continued for days, rivers rose beyond warning thresholds, and authorities moved tens of thousands of people before the storm finally crossed into China.
Four Landfalls and a Final Dissipation: Narra's Erratic Endgame
Narra's final phase began when its circulation turned back toward Hainan. The storm made its first landfall on August 20 at Longlou in Wenchang, Hainan, as a tropical depression. After crossing the island and later reorganizing over the surrounding waters, it returned to Hainan for a second landfall at Changjiang at 6:40 p.m. on August 25 with maximum sustained winds of 20 m/s.

The storm then crossed toward Guangdong. At approximately 3:25 a.m. on August 26, Narra made its third landfall near Xuwen County in Zhanjiang, with maximum sustained winds around 18 m/s. It weakened to a tropical depression as it moved farther inland and across the Leizhou Peninsula.
Xinhua News
Its fourth landfall came around 11 a.m. near Wuchuan in Guangdong, with winds near Force 6 on the Beaufort scale. The system continued northward and weakened rapidly. By the afternoon, the circulation had become difficult to identify as a distinct tropical cyclone, and the Hong Kong Observatory classified the former Narra circulation as a low-pressure area over western Guangdong.
Bastille Post
The four-landfall sequence is unusual because two of the landfalls occurred after Narra had already crossed the Hainan mainland once. Its track repeatedly brought the circulation back toward land rather than following a single uninterrupted coastal approach.
The final weakening also shows why the end of a cyclone warning does not necessarily mark the end of the flood threat. Rivers in northern Vietnam and southern China had already risen, soils were saturated and damaged infrastructure remained exposed. Narra's rainfall impacts consequently continued after its winds had fallen below tropical-storm strength.
The storm also affected operations well beyond immediate coastal communities. China's Wenchang space center, which had been preparing for the Chang'e 7 lunar mission, was operating under weather constraints during Narra's passage through Hainan. The launch was subsequently delayed, adding another example of how a relatively moderate tropical cyclone can disrupt activity when its rain and wind persist across a populated coastal region.

By August 26, Narra's circulation was weakening over Guangdong. The storm no longer had the organization it had maintained over the Gulf of Tonkin, and its track ended inland after the fourth landfall. The meteorological record closed with a tropical system that never reached extreme wind intensity but remained unusually persistent over a confined body of water.
Default Best Recommendation: Judge Narra by Rainfall Duration, Not Wind Alone
For disaster planning in the Gulf of Tonkin and adjacent coastal provinces, the most useful lesson from Narra is to treat slow movement and rainfall duration as primary warning signals, not secondary details behind maximum wind speed.
Forecast and emergency systems should give particular weight to five conditions:
Translation speed below normal tropical-cyclone levels. A storm moving at only a few kilometers per hour can keep heavy rain over the same watershed for much longer than a fast-moving system.
Repeated changes in direction. A looping or stalled track can invalidate assumptions based on a single expected landfall point.
Already saturated catchments. River flooding can intensify after the heaviest rainfall has passed because upstream runoff continues moving downstream.
Mountain and karst terrain. Northern Vietnam and Guangxi both contain areas where intense rain can quickly produce flash floods, landslides and rapid river rises.
Multiple landfalls. Narra's four landfalls show why an initial crossing does not necessarily mark the end of the hazard.
For coastal residents, fishing communities and local emergency managers, the practical priority is simple: follow rainfall, river and landslide warnings alongside the cyclone track. A tropical storm with moderate winds can still produce a major disaster when it remains over the same region for several days.
FAQ: What Narra's 2026 Track Reveals
- When did Typhoon Narra form?
The precursor tropical depression formed over the northern South China Sea on August 19, 2026. It later entered the Gulf of Tonkin and strengthened into Typhoon Narra on August 21.
台风说
- Why was Narra's track unusual?
Narra moved very slowly, generally around 3–5 km/h during its prolonged Gulf of Tonkin phase, and repeatedly changed direction. Instead of following a simple path toward land, it traced a compact, looping route over the gulf.
VietNamNet
- How long did Narra remain over the Gulf of Tonkin?
Narra maintained a tropical-cyclone circulation over the gulf for roughly five to six days. Vietnamese forecasters described this as exceptionally unusual for the region.
Vietnam News
- How many times did Narra make landfall?
Narra made four landfalls: Wenchang, Hainan, on August 20; Changjiang, Hainan, on August 25; Xuwen, Guangdong, early on August 26; and Wuchuan, Guangdong, later that morning.

Xinhua News
- Where did Narra cause the most serious flooding?
Guangxi in southern China experienced some of the most severe flooding. By 6 p.m. on August 23, 61,000 people were reported affected, 54,000 had been relocated and 8,087 had been moved into emergency accommodation.
China News
- How many people were affected in northern Vietnam?
The reported toll changed as assessments continued. By August 27, northern Vietnam had recorded three deaths and three injuries associated with Narra, while thousands of homes and large areas of agricultural land had been affected.
SGGP English Edition
- Was Narra a major typhoon?
No. Narra remained a relatively moderate tropical cyclone in terms of maximum wind strength. Its main danger came from its unusually slow movement, long residence over the Gulf of Tonkin and persistent rainfall.
- Did Narra enter the Philippines' area of responsibility?
No. Narra remained outside the Philippine Area of Responsibility, so PAGASA did not assign it a separate domestic storm name or issue a Philippine Tropical Cyclone Wind Signal for Narra. The name Narra itself was contributed by the Philippines to the regional international naming list.
- What does PAGASA Signal No. 1–5 mean in relation to Narra?
Those signals belong to PAGASA's Philippine warning system for tropical cyclones affecting its area of responsibility. They were not used for Narra because the storm did not enter the Philippine warning area.
- Why did Narra produce so much rain despite its moderate winds?
A storm does not need extreme winds to produce prolonged rainfall. Narra moved slowly and repeatedly remained over the same marine region, allowing moisture to continue feeding rainbands affecting northern Vietnam and southern China.
- What happened in Guangxi before Narra made its final landfalls?
Flooding was already severe in Guangxi before Narra reached its later Hainan and Guangdong landfalls. By August 23, multiple rivers had exceeded warning levels and authorities had already moved tens of thousands of residents.
China News
- Why were there four landfalls?
Narra crossed Hainan early in its life, later reorganized over surrounding waters, returned to Hainan, crossed the Leizhou Peninsula and then moved back into coastal Guangdong. Its weak steering environment and repeated changes in direction produced the unusual sequence.
- When did Narra finally weaken?
Narra weakened rapidly after its final landfall near Wuchuan on August 26. Later that day, its circulation was classified as a low-pressure area over western Guangdong.
- Was the flooding over when Narra weakened?
No. River flooding can continue after a tropical cyclone weakens because water from upstream catchments continues flowing into rivers and low-lying areas. Saturated slopes can also remain vulnerable to landslides after the storm center has moved away.
- What is the main meteorological lesson from Narra?
Narra shows why storm risk cannot be judged from maximum wind speed alone. A slow-moving tropical cyclone can create severe flooding when its rainbands repeatedly affect the same watersheds for several days.
