Extratropical cyclone, remnant low, tropical disturbance, or monsoon depressionThe NHC began monitoring a large area of disturbed weather in association with a tropical wave well southwest of the southern tip of the Baja California peninsula on July 13.[1] After crossing into the central Pacific, the disturbance gradually organized, and it acquired enough organization to be declared a tropical depression at 00:00 UTC on July 17.[2] An hour later, data from an ASCAT pass revealed winds up to 45 mph (75 km/h), and the depression was upgraded to Tropical Storm Wali.[3] Steered west-northwestward around a mid-level ridge to the cyclone's northeast, increasing wind shear caused the cloud pattern associated with Wali to become disorganized; at 18:00 UTC on July 18, the system was downgraded to a tropical depression, and by 00:00 UTC the following afternoon, Wali was declared a remnant low after having been devoid of deep convection. On July 19–20, the remnant moisture of Wali triggered a major rainfall event across Hawaii.[2]
Preparations and impact
edit
Although Wali had no impacts as a tropical cyclone, its remnants triggered a major rainfall event over Hawaii.[2] On July 19, a Flash Flood Watch was posted for the entire Hawaiian Islands, before being discontinued on July 21. Flood advisories were also issued for the Big Island and Oahu.[4][5]
