Hurricane Lowell Weakens to Category 3 but Kauaʻi Braces for Direct Brush, Hurricane Watch Issued

Hurricane Lowell has been downgraded from its peak intensity but remains a serious threat to Hawaii's westernmost islands, according to the state's Emergency Management Agency (HIEMA) [1]. The estate's own tracking instruments flagged the storm at 105 knots (roughly 121 mph) near coordinates 16.1, -163.4, a reading consistent with HIEMA's 5 p.m. Sunday advisory placing Lowell as a category 3 hurricane with 120 mph sustained winds, centred 50 miles south-southwest of Līhuʻe [1]. The storm's forecast track has shifted slightly east, prompting a Hurricane Watch for Kauaʻi County — meaning hurricane conditions are now considered possible there in the coming days — alongside an existing Tropical Storm Warning, according to HIEMA [1]. Lowell is expected to pass close to Niʻihau and Kauaʻi on Monday night and into Tuesday morning as a category 2 or possibly category 1 storm by the time of closest approach [1]. The storm's history has been volatile. It reached category 5 strength, with sustained winds of 157 mph or greater, overnight Friday, before dropping to category 4 by Saturday and category 3 by Sunday, according to NBC News, citing the National Hurricane Center [2]. As of the Sunday evening advisory reported by NBC, Lowell was about 500 miles south-southwest of Līhuʻe and moving north at 9 mph, with its forecast cone showing it passing just west of the main Hawaiian islands from south to north on Monday night [2]. Hawaii Governor Josh Green, quoted by NBC News, said the storm "has made its expected northward turn and remains forecast to pass west of Kauaʻi, but a slight shift east has increased the potential for tropical storm-force winds," adding that the greatest impacts are expected Monday, particularly on Kauaʻi and Niʻihau [2]. Green declared a state of emergency on Friday and activated the National Guard [2]. HIEMA's forecast warns of damaging wind gusts up to 74 mph in Kauaʻi County and up to 40 mph on Oʻahu on Monday and Tuesday, with extremely dangerous surf possible on southern and western exposed shores of Niʻihau, Kauaʻi and Oʻahu [1]. Rainfall could reach 12 to 14 inches on Niʻihau and Kauaʻi, with up to 8 inches on windward Maui and 2 to 6 inches elsewhere in the islands, raising the risk of flash floods and landslides in steep terrain, beginning as early as Sunday afternoon [1] [2]. National Weather Service warning coordination meteorologist John Bravender cautioned, as reported by NBC, that "just because we're on the edge of the cone doesn't mean we're safe" [2]. State officials said they were securing harbors, deploying emergency personnel and monitoring dams for possible breaches, according to the governor's office as relayed by NBC [2]. Lowell is one of three active tropical cyclones in the northern Pacific this week, alongside Tropical Storm Karina and Hurricane Marie, part of a season that has produced 15 named storms to date, according to Colorado State University figures cited by NBC [2]. Climate Central meteorologist Daniel Gilford attributed the intensity partly to unusually warm sea temperatures linked to El Niño [2]. HIEMA's next scheduled update is due September 7 at 8:45 a.m. HST, with routine updates otherwise issued at 5 a.m., 11 a.m., 5 p.m. and 11 p.m. [1]. What to watch next: whether Monday's track holds west of Kauaʻi or shifts further east into direct hurricane-force wind range.
