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), it was first noted as an area of convection in the South of Palau on May 31.

Meteorological history

On May 31 at 06:00 UTC, the Joint Typhoon Warning Center (JTWC) began monitoring an area of convection approximately 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 , though the JTWC assessed its development potential in the next day as low. 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. On June 3 at 18:00 UTC, the Japan Meteorological Agency (JMA) assessed that a tropical depression had formed over the Philippine Sea. On the next day at 03:00 UTC, the PAGASA gave the depression the local name ''Domeng'' as it was located east of Guiuan. 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 northwest of Palau.

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

Preparations, impact, and aftermath

Philippines

The PAGASA warned residents of possible floods and landslides, advising fishermen not to go to sea. Beginning June 5, classes were suspended in parts of Luzon and the province of Biliran. 73 people were evacuated in Calabarzon.

Maliksi enhanced the southwest monsoon in the Philippines, bringing monsoonal rains over Luzon and Visayas. 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. Trees were uprooted in Quezon City and Coron, Palawan, and in Calintaan, a temporary bridge was washed out by a river. 16 houses were damaged in San Fernando, Pampanga, six of which were completely damaged. A SkyJet Airlines flight on route from Metro Manila overshot the runway at Francisco B. Reyes Airport, injuring 2 of 86 on board, including the first officer. In Batangas, 8 municipalities lost power on June 9 at 3:00 PM local time, before being restored 6 hours later. In Metro Manila, overnight rains flooded at least 43 barangays, with several streets becoming impassable. Floods in parts of Quezon City's 4th congressional district reached . 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.
