Tropical Storm Maliksi (2018)

Severe Tropical Storm Maliksi, known in the Philippines as Severe Tropical Storm Domeng, was a tropical cyclone in June 2018 that brought rainfall to the Philippines and Japan. It caused 2 deaths and prompted the PAGASA to declare the beginning of the rainy season in the Philippines. The fifth named storm and 4th tropical cyclone in the Philippine Area of Responsibility (PAR),[1] it was first noted as an area of convection on May 31.

On May 31 at 06:00 UTC, the Joint Typhoon Warning Center (JTWC) began monitoring an area of convection approximately 95 nautical miles (175 km; 110 mi) south of Palau. The system was disorganized, with convection being located to the east of a broad and elongated low-level circulation. It was located in favorable conditions for development and sea surface temperatures in the area ranged from 29–30 °C (84–86 °F), though the JTWC assessed its development potential in the next day as low.[2] The system's low-level circulation began consolidating, and on June 2 at 00:30 UTC, the JTWC upgraded its development potential in the next day to medium.[3] On June 3 at 18:00 UTC, the Japan Meteorological Agency (JMA) assessed that a tropical depression had formed over the Philippine Sea.[4][lower-alpha 1] On the next day at 03:00 UTC, the PAGASA gave the depression the local name Domeng as it was located 675 kilometres (420 mi) east of Guiuan.[6] The depression absorbed an invest as convection covered the low-level circulation, and on 14:00 UTC the same day, the JTWC issued a Tropical Cyclone Formation Alert as it was located approximately 225 nautical miles (415 km; 260 mi) northwest of Palau.[7]

The depression began to exhibit signs of anticyclonic outflow as it was steered northward by a mid-level subtropical high-pressure area,[8] and on June 7 at 12:00 UTC, the JTWC upgraded the system to a tropical depression, assigning it the designation 06W.[9] 6 hours later at 18:00 UTC, both the JMA and the JTWC upgraded the depression to a tropical storm, with the JMA giving it the name Maliksi;[4][9] the system's circulation remained broad.[10] Maliksi passed by the western edge of the high-pressure area and turned northeast,[11] and on June 9 at 06:00 UTC, the JMA upgraded it to a severe tropical storm.[4] At 21:00 UTC, Maliksi exited the PAR, with the PAGASA issuing its final warning on the system.[12] On June 10 at 00:00 UTC, Maliksi peaked in intensity, with maximum sustained winds of 110 km/h (70 mph) and a minimum barometric pressure of 970 hPa (29 inHg) as it was located southeast of Okinawa.[4][lower-alpha 2] The JTWC assessed Maliksi to have peaked at the same time, also estimating the same windspeed in the 1-minute sustained standard.[9][lower-alpha 3] Maliksi began slowly accelerating to the northeast, developing a ragged eye as it became exposed to strong westerlies.[14] After reaching peak intensity, convection around the center began to decrease,[15] with the low-level circulation beginning to elongate.[16] Maliksi began extratropical transition as it was located over an unfavorable environment,[17] and on June 11 at 18:00 UTC, the JMA assessed that Maliksi completed its transition into an extratropical cyclone,[4] with its low-level circulation being displaced from its upper-level circulation;[18] the JTWC estimated extratropical transition began 6 hours earlier.[9] Maliksi's remnants dissipated east of Honshu on June 13.[4]

Preparations and impact

Philippines

Maliksi enhanced the southwest monsoon in the Philippines, bringing monsoonal rains over Luzon and Visayas. The PAGASA warned residents of possible floods and landslides, advising fishermen not to go to sea.[19] Classes in Cavite were suspended, with suspensions also occurring in parts of Rizal, Palawan, Occidental Mindoro, and Biliran.[20] A bridge received damage in San Fernando, Romblon, and on Tablas Island, power went out for a day due to fallen trees impacting power lines. Patients in the University of Santo Tomas Hospital were evacuated after floodwaters entered the building.[21] Trees were uprooted in Quezon City and Coron, Palawan, and in Calintaan, a temporary bridge was washed out by a river. A SkyJet Airlines flight en route from Metro Manila overshot the runway at Francisco B. Reyes Airport, injuring 2 out of 80 passengers. In Batangas, 8 municipalities lost power on June 9 at 3:00 PM local time, before being restored 6 hours later.[20] In Metro Manila, overnight rains flooded at least 43 barangays,[22] with several streets becoming impassable.[23] Floods in barangay Doña Imelda reached 5 feet (150 cm).[20] On June 9 at 11:00 PM local time, due to the heavy rainfall in Metro Manila, the PAGASA issued a red rainfall advisory for the area, along with other warnings for the regions of Calabarzon and Central Luzon.[24] Due to the effects of Maliksi, the PAGASA declared the beginning of the rainy season due to widespread rainfall in PAGASA weather stations.[25] A 27-year-old[20] from El Nido, Palawan drowned after falling from his jetski after it toppled, and a fisherman drowned after jumping into the water to fix the fishing net. 72 passengers and 2 vessels were stranded in Legazpi, Albay and Rapu-Rapu, with other ports in Oriental Mindoro suspending their operations.[22]

Japan

On the small island of Hachijō-jima, 287.5 millimetres (11.32 in) of precipitation was recorded, and on Kitadaitōjima, maximum winds were recorded at 23.2 metres per second (85 km/h; 50 mph).[26] In Chichibu, Saitama, there were rains around noon as the storm was approaching the Kantō Region, though winds were not strong.[27]

Notes
  1. The Japan Meteorological Agency is the official Regional Specialized Meteorological Center for the western Pacific Ocean.[5]
  2. All winds are in 10-minute sustained standards, as per the Japan Meteorological Agency,[4] unless otherwise stated.
  3. The Joint Typhoon Warning Center uses 1-minute sustained winds to measure wind speeds for tropical cyclones.[13]
