近1英尺截至9月26日部分地区观测到的降雨量 7
8–10英寸预计新增降雨量,尤其是南部和东部 7
50–60 mph部分地区观测到的阵风 7
诺洛路径的变化令人欣慰,但也容易被误读。预计飓风将向西移动,远离直接袭击夏威夷的路径;大岛的飓风观察于9月26日取消。取消观察时,夏威夷县仍处于热带风暴警告之下,全岛仍处于洪水观察之下。两项警报周日晚些时候的状态尚未得到核实。飓风观察取消针对的是出现飓风条件的可能性;这并不意味着雨停了,也不意味着饱和的山坡已无危险。38
布伦南说,大岛部分地区已出现热带风暴天气,阵风达到每小时50至60英里,尤其是在较高的山脉附近。他在周六发布的更新中说,诺洛中心位于大岛以南略超过150英里处,并未继续靠近。他预计风暴向西移动后,天气状况将从周六夜间开始好转,尤其是在周日和周一。这是天气预报,并非对所有受影响社区实际状况的核实报告。7
警报如何变化
诺洛逼近夏威夷
周五的警报基于一份严峻的预报。当时的报道将诺洛定为2级飓风,持续风速为每小时105英里,移动速度约为每小时5英里。预报员预测,受影响地区降雨量将达到10至25英寸,局部地区可能超过2英尺;当时处于热带风暴观察之下的毛伊岛,降雨量可能高达10英寸。一份早期预报讨论认为,诺洛可能增强为4级飓风,风速最高可达每小时140英里。这只是一种可能性,经核查的报道并未证实诺洛曾达到这一强度。1
最接近风暴前的准备工作
我们在9月10日的报道中提到,另一场近海飓风洛厄尔在未登陆的情况下对考艾岛和尼豪岛造成损害。诺洛是另一场风暴,其尚未消除的危险在于向西转向后,大岛可能出现降雨。经核查的报道尚未证实最终降雨总量、洪水或泥石流损害、伤亡情况,以及此后警报的变化。近一英尺的降雨观测属实;令人担忧的后续降雨及其后果仍有待确认。

播出原貌
- On September 10 we reported offshore Lowell damaged Kauaʻi and Niʻihau. Now Nolo drenches Hawaiʻi Island. Nolo’s hurricane watch has been canceled, but rain is still intensifying, and flooding and mudslides could be life-threatening. How much danger remains after the storm’s turn away from the island?
- By Saturday, September 26, some places on the Big Island had received nearly a foot of rain. That is an observation from some locations, not a final total for the island. Another eight to ten inches was possible, especially across its south and east. Whether that additional rain fell, and where, has not been established.
- The distinction matters on ground that has already taken heavy rain: a forecast is not a measurement, but further rainfall could send water into roads and homes or destabilize slopes. The September 27 rain-risk update does not establish that catastrophic flooding or a mudslide actually occurred.
- Tropical-storm conditions were already occurring on Hawaiʻi Island on Saturday. Gusts of fifty to sixty miles per hour had occurred in some places, particularly near higher mountains. A separate forecast put possible gusts as high as seventy-five miles per hour; that higher figure was not an observed wind speed. By September 27, strong winds and rough surf had also reached Oʻahu, including the Waikīkī and Diamond Head area. No specific damage or measured surge there has been established.
- Nolo’s center stayed offshore. One Saturday update placed it a little more than 150 miles south of the Big Island and expected it to move west, taking the heaviest rain away. At eight that morning, a separate account put the center about 145 miles south of Kaʻū, moving west at three miles per hour. Those approximate distances refer to different places and reporting times; they are not a measured change in distance from one point. Conditions were expected to improve from Saturday night, especially on Sunday and Monday, but improvement in the affected communities has not been verified. No direct landfall was projected. An offshore center, though, does not keep its rain, wind or surf offshore.
- The Big Island’s hurricane watch was still in effect at eight Saturday morning and was canceled later that day; the exact cancellation time is not verified. A tropical-storm warning for Hawaiʻi County and a flood watch across the island remained when it was canceled. We cannot establish whether either alert was still in force later Sunday. A watch cancellation is a change in the expected hurricane-wind threat, not evidence that floodwater has receded.
- Friday’s outlook explains why preparations were extensive. On September 25, Nolo was a Category Two hurricane with sustained winds of 105 miles per hour, moving at about five miles per hour. The Big Island entered a hurricane watch, meaning hurricane conditions were possible within roughly 24 to 36 hours; Maui was under a tropical-storm watch. Forecasts warned of ten to twenty-five inches of rain across affected areas, locally more than two feet, and up to ten inches on Maui. An early discussion allowed for Category Four strength and winds up to 140 miles per hour over the next 72 hours. That was a possibility, not a strength verified to have occurred.
- Other early rainfall projections included fifteen to twenty inches widely and a possible local maximum of 35 inches. In one forecast, an estimate as high as three feet was revised down to around two feet; another still allowed locally more than two feet. Those changing ceilings cannot be treated as final accumulation. Saturday’s more localized update separated the nearly one foot already recorded in some places from the additional eight to ten inches still possible.
- The storm’s reported strength changed too. An earlier Saturday account still placed Nolo at Category Two with winds above 100 miles per hour. By Saturday evening, it was reported at Category One with sustained winds above ninety. A separate September 27 account described Category Two and 105-mile-per-hour winds, but did not identify a Sunday advisory supporting that as the latest measurement. The latest clearly dated strength in this material is Saturday evening’s Category One report; Nolo’s Sunday intensity is not verified. A bulletin valid early Saturday had placed the storm near 16.9 degrees north and 155.3 degrees west, moving north at three knots with ninety-knot sustained winds. That is a historical position, before the later westward turn, not a Sunday fix.
- People had prepared before the closest approach. Shelters opened in Hawaiʻi and Maui counties. In Hilo, residents described hunkering down, and many events were canceled as a precaution. State and county offices, public schools and University of Hawaiʻi campuses on Hawaiʻi Island were set to close Thursday and Friday, September 24 and 25; Maui County closures expanded Friday. Parks, campsites, forest reserves, state-managed trails and natural-area reserves closed on Hawaiʻi Island beginning Thursday, and on Maui and Molokaʻi beginning Friday. Those are dated decisions, not proof that every site remains closed. Reopening dates have not been verified.
- President Donald Trump approved a pre-landfall federal emergency declaration on September 25 after Hawaiʻi requested it. It covers Hawaiʻi, Kauaʻi and Maui counties and the City and County of Honolulu. It authorizes federal emergency protective measures, including direct federal assistance, with a seventy-five-percent federal share of eligible costs. That does not mean seventy-five percent of all storm damage will be reimbursed, or establish that any household has received aid. The federal incident description calls the event Tropical Storm Nolo, while the governor’s announcement calls the approaching system Hurricane Nolo; neither administrative wording establishes its later measured strength.
- One account mentioned a closed Big Island mountain highway, but its name, location, cause, damage and reopening time have not been verified. The answer to the flood question is therefore limited: nearly a foot had fallen in some places by Saturday, more rain was possible, and the September 27 risk remained serious even as Nolo turned away. There is no verified final island rainfall total, Sunday storm advisory or later warning status in the checked material. Nor is there a confirmed storm death, injury, flood-damage total or landslide-damage total.
