Tropical Storm Krovanh (2020)

Tropical Storm Krovanh, known in the Philippines as Tropical Depression Vicky, was a tropical cyclone which caused deadly flooding in the Philippines during December 2020. The 31st depression and 23rd and final named storm of the 2020 Pacific typhoon season, Krovanh originated from a tropical depression which was first monitored by PAGASA, late on December 17. The system strengthened with PAGASA naming it Vicky, meanwhile the JMA monitored it as a low pressure area. The depression then made several landfalls over the Philippines on December 18–19, before moving out of the PAR on December 20 as it strengthened into a tropical storm according to the JMA and was named Krovanh. However, Krovanh was downgraded back to a tropical depression the next day, with the JTWC issuing their final advisory on December 22.

On December 17 at 21:00 UTC, the PAGASA began issuing bulletins for a system 140 nautical miles (260 km) east-southeast of Davao.[2][3] The PAGASA had already recognized the system as a tropical depression and named it Vicky, however at the time, the Japan Meteorological Agency (JMA) only recognized the system as a low-pressure area.[4] The next day, the JMA followed suit and recognized the system as a tropical depression.[5] At 14:00 PHT (6:00 UTC), the system made landfall in Baganga, Davao Oriental.[6] 9 hours later, it emerged off the coast of Misamis Oriental and entered the Bohol Sea, later entering the Sulu Sea on the next day at 5:00 PHT (21:00 UTC).[7] On December 19 at 23:00 PHT (15:00 UTC), Krovanh made its second landfall over central Palawan, emerging into the West Philippine Sea shortly after.[8][9] As the storm traversed the South China Sea, the system had strengthed into a tropical storm according to the JMA as it emerged into a region of relatively favorable atmospheric conditions, thus given the name Krovanh.[10] On December 20 at 14:00 PHT (6:00 UTC), Krovanh left the Philippine Area of Responsibility, although storm signals were still raised for the Kalayaan Islands.[11] The PAGASA then upgraded Krovanh into a tropical storm, and issued a Signal No. 2 warning for the Kalayaan Islands.[12] The next day, December 21, Krovanh was downgraded into a tropical depression by both the JMA and by the PAGASA in their final advisories for the storm.[13][14] The JTWC then issued their final warning on Krovanh the next day shortly after most of its central convection had dissipated due to increasingly hostile wind shear.[15]

Preparations and impact

Philippines

Large swaths of Visayas and Mindanao were placed under Signal No. 1 warnings due to Krovanh.[16] Sea travel was subsequently suspended in the areas affected by the warnings.[17] Roughly 10,000 people stayed in shelters.[18] Floods and landslides were triggered in Cebu, Agusan del Sur, Davao de Oro, and in Leyte, where two senior citizens were killed in a landslide. In Lapu-Lapu City, 300 residents were forced to evacuate after 76 houses near the shore were swept into sea.[19] Damages have been estimated to total up to ₱213.2 million (US$4.48 million). At least nine people were killed by the effects of Krovanh.[20] At least 31,408 families were affected by the storm in the Philippines.[21]

Malaysia

The Malaysian Meteorological Department issued an advisory for the state of Sabah, for the possibility of rough seas and gusty winds associated with Krovanh.[22]
