On May 27, the Japan Meteorological Agency (JMA) and the Joint Typhoon Warning Center (JTWC) noted the persistence of an area of atmospheric convection about 425 nautical miles (787 km; 489 mi) south-southeast of Guam.[5] The convection's nearby environment exhibited low vertical wind shear and warm 29–30 °C (84–86 °F) sea surface temperatures; ideal conditions for tropical cyclogenesis.[6] The JMA assessed the area of convection to have developed into a tropical depression on May 29 at 06:00 UTC around 06°N 136°E.[7] The PAGASA made a similar assessment in a Tropical Cyclone Advisory issued at 15:00 UTC.[8] The JTWC later followed with their own assessment, identifying the center of the newly developed tropical depression approximately 35 nautical miles (65 km; 40 mi) south-southeast of Angaur, Palau and assigning the designation 04W.[9] As the system tracked westward, it entered the Philippine Area of Responsibility at 01:00 PHT (17:00 UTC).[10] The PAGASA then named the storm Dante in its first Tropical Cyclone Bulletin for the storm.[11]

Choi-wan intensified further in the Philippine Sea and the JTWC had determined that the depression strengthened into a tropical storm.[12][13] Later on, the Japan Meteorological Agency also upgraded the system into a tropical storm, and the storm was then named Choi-wan.[14] Choi-wan's center was exposed due to a tropical upper tropospheric trough from the northeast, inducing shear on the system.[15] The system continued to move northwestwards before taking a west-northwestward track while continuing to struggle from moderate shear.[16] At 20:30 PHT (01:30 UTC), Choi-wan struck Sulat, Eastern Samar as a minimal tropical storm.[17] Midway through its transit through the Philippines, the JTWC then downgraded it into a tropical depression.[18][16]

It then made a second landfall on the municipality of Cataingan on the island of Masbate at 17:00 UTC on June 1[19] before it made another landfall in Balud at 19:30 UTC, still in the province.[20] It traversed the Sibuyan Sea then made a fourth landfall in the island of Romblon, Romblon at 00:00 UTC on the next day.[20] It crossed the Romblon Pass before making a fifth landfall in the municipality of San Agustin, fifty minutes after the previous one, still in the province.[20] Choi-wan then headed northwest while struggling to reorganize under the waters of the Tablas Strait, and then making a sixth landfall in Pola, Oriental Mindoro at 06:00 UTC.[20] It traversed the island of Mindoro with the system being disorganized again before exiting into the Verde Island Passage. Choi-wan then made a seventh landfall in Marincaban Island, Tingloy, Batangas at 11:20 UTC.[20] Continuing to move northwestwards, the system made an eighth and final landfall in the Calatagan Peninsula in Batangas at 12:00 UTC on June 2 before exiting back into the South China Sea.[21] Despite the system being predicted to dissipate in the area, warm sea surface temperatures aided Choi-wan to restrengthen to a tropical storm at 03:00 UTC on the next day.[22]

A large high-pressure area in the central Pacific Ocean and an anticyclone over China turned the system north-northeaswards, with the storm exiting the Philippine Area of Responsibility at 18:00 UTC.[23] Dry air yet again impacted the storm, with Choi-wan's convection being displaced to the west as it approached Taiwan and as a result, the storm weakened again to a tropical depression per the estimates of PAGASA and JTWC.[24] At 20:00 UTC on June 3, Choi-wan reentered the PAR before the system started to merge with an existing meiyu front which extends from China to the Japanese Islands and at the same time, passing to the south of Taiwan.[25] At 1:00 UTC on June 4, the system reexited the PAR for the second and final time as it headed north-northeastwards.[26] While passing through the Ryukyu Islands, the JMA issued their final warning on Choi-wan as it transitioned to an extratropical storm, still embedded in the front.[27]
