These agencies included the Tropical Storm Risk (TSR) Consortium of University College London, PAGASA, Vietnam's National Center for Hydro-Meteorological Forecasting and Taiwan's Central Weather Administration.

On the morning of August 12, Maria made landfall in Iwate Prefecture as a tropical storm, bringing strong winds and dumping heavy rains in northern Japan.

As it moved northwestwards, a small patch of deep convection developed over the northern portion of a partially exposed low-level circulation, resulting in the system weakening into a tropical storm on November 11.

With JTWC, the TCFA was initiated twice, citing a high chance of development, however, as it crossed between Visayas and Mindanao, PAGASA issued its final warning for Querubin on December 18 as it downgraded into a well-marked disturbance.

On May 21, the Joint Typhoon Warning Center (JTWC) began tracking an area of atmospheric convection 441 km (274 mi) southeast of Palau, noting that the system was moving northwestward towards an environment favorable for tropical cyclogenesis.

At the time, the disturbance was in a marginal environment for development, with high vertical wind shear offsetting good divergence aloft alongside warm sea surface temperatures.

[62] The southwest monsoon, combined with Tropical Storm Prapiroon, brought heavy rains to southern and northern Luzon, triggering widespread flash floods that resulted in at least 126 deaths and caused damage estimated at US$2.31 billion across several countries.

[77][78] Typhoon Gaemi and Prapiroon, along with its precursor, significantly impacted the southwest monsoon over the Philippines, leading to heavy rainfall that caused 23 deaths, 9 people missing, and US$32.9 million in damages across several countries.

[82] Later that day, the JTWC began tracking it, noting the depression was in an environment with low to moderate wind shear, warm sea surface temperatures, and good equatorward outflow aloft.

[83] At 09:00 UTC on August 6, the JTWC issued a TCFA on the disturbance, which was located 423 mi (682 km) north-northwest of Iwo Jima, along the eastern periphery of the monsoon gyre,[84] prior to it being designated as 06W.

[112] The JMA reported that Ampil reached its peak intensity at 12:00 UTC that day with 10-minute sustained winds of 155 km/h (100 mph) and a central pressure of 950 hPa (28.05 inHg) before making its closest approach to Japan, and transitioned into an extratropical low on August 19.

[117] Satellite imagery revealed that a central dense overcast obscured the center, leading to the depression strengthening into a tropical storm named Wukong by the JMA,[118] although moderate vertical wind shear displaced the deep convection to the southeast.

[139][140] Shortly after, the depression intensified into a tropical storm and was named Shanshan by the JMA due to low vertical wind shear and warm sea surface temperatures.

Satellite imagery depicted that the low-level circulation center (LLCC) of Leepi passed under strong upper-level southwesterly flow, indicated by a broad region of cirrus streamers.

[199] Pulasan was characterized by a large cyclonic circulation exceeding 690 miles (1,111 km) and extensive gale-force winds, leading the JTWC to classify it as a monsoon depression at 06:00 UTC on September 16,[200] before later upgrading it to a tropical storm and designating it as 15W.

Heavy rains from Pulasan caused major flooding and landslides across the Noto Peninsula in Japan, leaving one missing, destroying many buildings and forcing 60,700 residents to be evacuated.

[215][216] On September 18, the JTWC canceled their TCFA due to an obscured low-level circulation with flaring convection, while the depression had drifted into an area of moderate vertical wind shear.

[228] At the latter part of September 27, JTWC reported that Cimaron became a remnant low due to its increasing vertical wind shear, resulted of eroding of the low-level circulation center (LLCC).

On September 26, the JMA reported a tropical depression 250 km (155 mi) south-southwest of Kadena Air Base, Japan,[232] characterised by a partially exposed low-level circulation centre with persistent deep convection in the southern semicircle and formative banding to the north.

[237] which had since become cloud-filled,[238] Early on October 1, the JMA upgraded Krathon to a violent typhoon, estimating its peak intensity with a minimum central pressure of 915 hPa (27.02 inHg) and 10-minute maximum sustained winds of 195 km/h (120 mph).

[251] It made landfall in Thua Thien-Hue and Da Nang at about 10 AM local time on October 27,[252] before drifting slowly inland while moving southwestward over the past few hours.

[280] At 18:00 UTC that same day, the JMA upgraded the system to a tropical storm named Yinxing,[281] as it exhibited improved convective banding tightly wrapping around the obscured low-level circulation center.

[293] It later developed into a more compact cold central cover with deepening overshooting cloud tops and a 22 miles (35 km) diameter eye that became increasingly symmetrical and sharply defined.

[306] Meanwhile, the JMA upgraded Man-yi to a violent typhoon, estimating its peak intensity with a minimum central pressure of 920 hPa (27.17 inHg) and 10-minute maximum sustained winds of 195 km/h (120 mph).

[11][311] Man-yi accelerated northwestward over the South China Sea, rapidly deteriorating as the storm experienced a low-level northeasterly cold surge and increased vertical wind shear.

On November 8, the JMA reported that a low-pressure area had formed 620 km (386 mi) north of Yap,[315] Environmental analysis indicated a favorable environment for further development, with sea surface temperatures of 30–31 °C (86–88 °F), strong poleward outflow aloft, and low vertical wind shear.

[318] Satellite imagery shows that Toraji was undergoing rapid intensification, with a small system displaying an elongated, compact CDO feature, measuring around 81–92 miles (130–148 km) in diameter.

[324] On November 11, Toraji made landfall on Dilasag, Aurora, on Luzon Island at around 8:10 AM PHT (00:10 UTC),[325] before moving inland over mountainous terrain, which caused significant weakening.

[326] Satellite imagery showed a weakening of deep convection at the storm's center, resulting from strong southerly vertical wind shear as it became embedded in the low-level northeasterly flow associated with a cold surge.

[334] On November 13, the JTWC reported that the system had peaked as a Category 4-equivalent super typhoon after Usagi attained 1-minute sustained winds of 240 km/h (150 mph) [335] and a central pressure of 940 hPa (27.76 inHg).
