Tropical Storm Bavi, known in the Philippines as Tropical Storm Betty, was an early-season tropical storm in the 2015 Pacific typhoon season. The system influenced the trade winds over the Pacific Ocean and was partially responsible for one of the strongest trade wind reversals ever observed. The system was first noted as a tropical disturbance during March 8, 2015, while it was located to the southeast of Kwajalein Atoll in the Marshall Islands. Over the next couple of days the system moved north-westwards through the Marshall Islands, before it was classified as a tropical depression during March 10. The system subsequently moved north-westwards and continued to develop further, before it was classified as the third tropical storm of the 2015 Pacific typhoon season and named Bavi by the Japan Meteorological Agency (JMA) during March 11. After continuing its north-westwards movement, the system peaked as a tropical storm during March 14, before it started to weaken as it approached the Mariana Islands. The system subsequently passed over Guam during the next day, before continuing its west-northwestwards movement as it gradually weakened over the next few days. The system entered the Philippine area of responsibility, where it was named Betty by PAGASA during March 17 as the system weakened into a tropical depression. The system was subsequently last noted during March 21, as it dissipated over the Philippines.
Bavi and its precursor tropical disturbance impacted eastern Micronesia, with strong to gale-force winds of between 45–65 km/h (30–40 mph), reported on various atolls in the Marshall Islands. Considerable damage was reported on the islet of Ebeye, on the main atoll of Kwajalein, a small amount of tree damage was reported, while several old steel structures were made too dangerous to use. Overall damages in the Marshall Islands were estimated at US$2.1 million, while a fishing vessel and its crew of nine were reported missing during March 12. Bavi and its precursor also had severe impacts in Kiribati. After impacting Eastern Micronesia, Bavi approached the Mariana Islands, with its circulation passing over Guam during March 15, where it caused the highest waves to be recorded on the island in a decade. Bavi also impacted the Northern Mariana Islands of Rota, Tinian and Saipan, where power outages were reported and five houses were destroyed. Total property damages within the Mariana Islands were estimated at around US$150 thousand.
