Tropical Storm Noul, also known in the Philippines as Tropical Storm Leon, was a weak, but deadly tropical cyclone that impacted central Vietnam, which had been affected by Tropical Storm Sinlaku more than one month earlier. Noul originated from a tropical system in the Philippine Sea in September 15. The system was upgraded into a tropical depression later that same day by JMA, with JTWC and PAGASA following suit in 15:00 UTC, with PAGASA assigning the local name Leon to the developing tropical cyclone. As Leon was leaving the area of responsibility, Leon intensified into a tropical storm and was assigned the international name Noul by JMA. Noul would make landfall between Quảng Trị and Thừa Thiên-Huế provinces in September 18 before degenerating into a remnant low over Thailand later that day.
Noul caused six deaths and losses of US$175.2 million in Vietnam. [1] In Cambodia, Noul killed 12 people, in which 8 of them are killed by lightning strike on Battambang Province, 3 of them drowned in Preah Sihanouk and Koh Kong provinces, and a person from Pailin Province is missing and presumed dead. [2]
On September 14 at 12:00 UTC, the Japan Meteorological Agency (JMA) began issuing warnings on a tropical depression as it was moving west-northwest. [3] The system continued organizing, and on September 15 at 02:00 UTC, the Joint Typhoon Warning Center (JTWC) issued a Tropical Cyclone Formation Alert on the system as it was located over the Philippines. [4] The system was in a favorable environment, though strengthening was limited due to the disorganized structure. [5] Convection, albeit disorganized, began covering the low-level circulation, and at 15:00 UTC, the JTWC upgraded the system to a tropical depression, giving it the unofficial designation of 13W as it was located approximately 159 nautical miles (294 km; 183 mi) southwest of Manila. Sea surface temperatures in the area ranged from 30–32 °C (86–90 °F). [6] At the same time, the PAGASA began issuing severe weather bulletins on the depression, giving it the local name Leon. [7] 3 hours later at 18:00 UTC, the JMA upgraded the depression to a tropical storm, assigning it the name Noul. [8] At 21:00 on September 16, the storm left the PAR and PAGASA issued its final warning on the system. [9] At 03:00 UTC September 18, Noul made landfall between Quảng Trị and Thừa Thiên-Huế provinces. At 9:00 UTC, the JTWC issued its final warning on the system. [10] After being downgraded to a low pressure area (LPA), Noul followed a westward path and emerged in the Indian Ocean.[ citation needed]
A few days before the storm hit Vietnam, the Vietnamese government closed three airports and evacuated more than one million people in the affected areas. [11] [12] [13] Noul damaged homes and knocked down trees and power lines in Hue, Vietnam. [14] Heavy precipitation amounts peaking at 310 mm (12.20 inches) fell in Da Nang. [15] The storm caused 6 deaths and 705 billion đồng (US$30.4 million) in damage. [16] [17] [18]
