Part of the 2025 Pacific typhoon season | |
Typhoon Kalmaegi,known in the Philippines as Typhoon Tino,is an active tropical cyclone currently impacting Vietnam after devastating portions of the central Philippines,particularly Cebu. The twenty-fifth named storm and twelfth typhoon of the 2025 Pacific typhoon season,Kalmaegi originated from an area of convection on October 30. The following day,it was later classified as a tropical depression as the Joint Typhoon Warning Center (JTWC) issued a Tropical Cyclone Formation Alert (TCFA) at 02:00 UTC. At 12:00 UTC,the Japan Meteorological Agency (JMA) upgraded the system to a tropical storm and assigned it the name Kalmaegi,as environmental conditions became increasingly favorable for development. The JTWC followed suit at 21:00 UTC,also designating it as a tropical storm. The system entered the Philippine Area of Responsibility (PAR) at 05:30 PHT on November 2 (21:30 UTC on the previous day) and was named Tino by the Philippine Atmospheric,Geophysical,and Astronomical Services Administration (PAGASA). At 12:00 UTC,the JMA upgraded Kalmaegi to a severe tropical storm. By 03:00 UTC on November 3,PAGASA,the JTWC,and the JMA all upgraded the system to typhoon status,citing a highly favorable environment for rapid intensification.
Tropical Cyclone Wind Signal No. 4,indicating potential winds of 118–184 km/h (73–114 mph) was hoisted in numerous areas. Kalmaegi generated strong winds and flooding that left at least 142 people dead and 127 others missing in the Philippines,mostly in Cebu, [1] with at least one additional death in Vietnam.
Kalmaegi originated from an area of convection that developed on October 30, located about 313 nautical miles (580 km) east-southeast of Yap. Satellite imagery showed cycling deep convection over a poorly organized low-level circulation center (LLCC). The disturbance was embedded in a favorable environment for tropical cyclogenesis, with low wind shear and warm sea surface temperatures (SSTs). [2] On the following day, the JMA classified the system as a tropical depression as its LLCC slowly consolidated. [3] The JTWC noted that the depression remained in an environment conducive for further development, characterized by light vertical wind shear and warm SSTs. [4] Around 05:00 PHT (21:00 UTC on the previous day) on November 1, PAGASA also classified the system as a tropical depression. [5]
The JTWC issued a TCFA at around 02:00 UTC on November 1, citing a high probability of further development as the system moved west northwestward. [6] The JTWC noted a broad low-level circulation center (LLCC) with convection concentrated north of the center and some curved banding features. Favorable environmental conditions persisted, supported by good poleward outflow. [7] As the LLCC gradually consolidated and convective banding wrapped around its northern semicircle, the system began tracking northwestward along the southwestern edge of a subtropical ridge. [8] [9] At 06:00 UTC, the JMA noted that, while the system remained in a favorable environment, the limited organization of its structure caused it to maintain its intensity for several hours. [10] The JTWC later designated the system as 31W at 09:00 UTC. [11]
At around 12:00 UTC, the JMA upgraded 31W to a tropical storm, assigning it the name Kalmaegi. [12] The JTWC observed a symmetric central dense overcast (CDO) enveloping the LLCC and described the system as compact as it tracked along the southern periphery of a subtropical ridge located to the northeast. [13] By 21:00 UTC, the JTWC also classified Kalmaegi as a tropical storm, citing an expanding CDO and a highly favorable environment for further intensification. [14] The storm later entered the PAR at 05:30 PHT on November 2 (the day before at 21:30 UTC) and was given the local name Tino. [15] Satellite imagery showed robust radial outflow and intense central convection, with the deepest convection concentrated over the northern and western semicircles. [16]
At 17:00 PHT (09:00 UTC), PAGASA upgraded Kalmaegi to a severe tropical storm. [17] The JMA noted a brief slowdown in intensification before the system resumed strengthening. [18] According to the JTWC, deep convective bursts developed over the center, with a banding feature forming to the north. Microwave imagery showed a small, forming eye and strong convection displaced slightly to the south, indicating increasingly favorable conditions for further intensification. [19] Three hours later, the JMA also upgraded Kalmaegi to a severe tropical storm. [20] [21] The JTWC noted two distinct clusters of deep convection forming an oblong-shaped CDO. [22] By 18:00 UTC, two lobes became apparent: the southeastern lobe was centered over the low-level circulation and served as the primary region of deep convection, while the northwestern lobe exhibited strong poleward outflow. [23] At 03:00 UTC on November 3, the JTWC upgraded Kalmaegi to a typhoon, citing a consistently favorable environment and strong outflow supported by trade winds. Multispectral satellite imagery showed a compact core with deep convection wrapping closely around the center. [24] [25] At the same time, the JMA and PAGASA also upgraded the system to a typhoon when it was approximately 368 nautical miles (682 km) north-northeast of Sonsorol. [26] [27] The JTWC later noted that deep convection wrapped around the core but an eye failed to develop due to persistent northeasterly wind shear, despite otherwise favorable conditions. [28]
On November 4, Kalmaegi intensified into a Category 2-equivalent typhoon before making landfall in Silago, Southern Leyte at around 00:00 PHT (16:00 UTC). It then weakened back into a Category 1 typhoon due to land interaction. [29] The system went on to make three additional landfalls in Borbon, Cebu, Sagay, Negros Occidental, and San Lorenzo, Guimaras at 05:10 PHT (21:10 UTC), 06:40 PHT (22:40 UTC), and 11:10 PHT (03:10 UTC), respectively. [30] [31] The repeated landfalls caused Kalmaegi to weaken slightly and slow as it moved into the Iloilo Strait. [32] At 13:20 PHT (05:20 UTC), Kalmaegi made its fifth landfall over Iloilo City. [33] It then made a sixth landfall in Magsaysay in the Cuyo Archipelago at 19:30 PHT (11:30 UTC). [34] At 04:10 PHT (20:10 UTC) on November 5, Kalmaegi made its seventh landfall over Batas Island in Taytay, Palawan, [35] followed by an eighth landfall at 04:40 PHT (20:40 UTC) over El Nido, Palawan. [36]
Afterwards, Kalmaegi emerged over the South China Sea, where it began reorganizing under favorable oceanic and atmospheric conditions, with satellite imagery showing improved structure and strengthening convection. [37] It rapidly intensified as a broad region of diffluent outflow developed and a ragged eye formed. [38] The JTWC later noted that Kalmaegi began to gradually weaken on approach to Vietnam due to northeasterly wind shear, although the environment remained marginally supportive, and satellite imagery continued to show a well-defined eye. [39] The typhoon made landfall over south central Vietnam on November 6. [40]
At 11:00 PHT (03:00 UTC) on November 2, PAGASA issued Tropical Cyclone Wind Signal No. 1, indicating winds of 24 to 38 mph (39 to 61 km/h) after 36 hours, to Eastern Samar, Dinagat Islands, Siargao, and Bucas Grande. [41] Seven more provinces were put on Signal No. 1 six hours later: six in the Visayas and one in Mindanao. [17] At 23:00 PHT (15:00 UTC), Guiuan, Salcedo, and Mercedes in Eastern Samar, and the Siargao and Bucas Grande Islands, were placed in Signal No. 2, indicating winds of 39 to 55 mph (62 to 88 km/h) in a 24-hour period as more areas were placed under Signal No. 1. [42] By 05:00 PHT on November 3 (21:00 UTC the previous day), Signal No. 2 was hoisted to an additional 11 provinces. [43] At 08:00 PHT (00:00 UTC), Guiuan, Mercedes, the Dinagat Islands, and the Siargao and Bucas Grande Islands were added to Signal No. 3, signifying winds of 55 to 73 mph (89 to 117 km/h) in 18 hours. [44] At 11:00 PHT (03:00 UTC), the southern portion of Eastern Samar, Marabut in Samar, the central and southern portions of Leyte, Southern Leyte, Camotes Islands, the eastern portion of Bohol, Dinagat Islands, the northern portion of Surigao del Norte were issued Signal No. 3. [27] Three hours later, the Dinagat, Siargao, and Bucas Grande Islands were upgraded to Signal No. 4, indicating winds of 73 to 114 mph (118 to 184 km/h) winds in 12 hours. [45] At 17:00 PHT (09:00 UTC), Guiuan, the southern portion of Leyte, Southern Leyte, the Camotes Islands, and the northeastern portion of Bohol was added to Signal No. 4. [46] Three hours later, Mercedes, the western portion of Leyte, and the northern portion of Cebu was added to Signal No. 4. [47] At 23:00 PHT (15:00 UTC), the northernmost portion of Negros Oriental, the northern portion of Negros Occidental, and Guimaras was added to the signal. [48] Three hours later on November 4, the central and southern portions of Iloilo and the southern portion of Antique was added. [49] At 08:00 PHT (00:00 UTC), the entirety of Iloilo and the southern portion of Aklan was added. [50] As the system moved closer to Palawan, the northern portion of the province and the Calamian and Cuyo Islands were added to Signal No. 4. [51] At 17:00 PHT (09:00 UTC), all Signal No. 4 and 3 alerts were removed. [52] By November 6, only the Spratly Islands remained; [53] PAGASA issued their final alert at 17:00 PHT (09:00 UTC) that same day. [54]
