The 2026 tropical cyclone season in the northeastern and central Pacific basins has been busy. By September 28, the number of named storms in the region had grown to 20, of which nine had reached hurricane strength. For comparison, the 1991-2020 average by that date is 13.5 named storms with 7.4 hurricanes.
2026年东北部和中部太平洋盆地的热带气旋季节非常繁忙。截至9月28日，该地区已命名的风暴数量已增至20个，其中9个已达到飓风强度。相比之下，1991 年至 2020 年该日期的平均命名风暴为 13.5 次，飓风为 7.4 次。
An image from NASA’s EPIC (Earth Polychromatic Imaging Camera) on the DSCOVR (Deep Space Climate Observatory) satellite, acquired on September 27, shows the basin again rife with powerful storms. Hurricane Nolo near Hawaii and Hurricane Polo off the Baja California peninsula were lashing land with high winds, storm surge, and heavy rain. On either side of Polo, Tropical Storm Rachel and Post-Tropical Cyclone Odalys were contributing to treacherous conditions along the Mexican coast and in the southwestern U.S., respectively.
9 月 27 日，美国宇航局 DSCOVR（深空气候观测站）卫星上的 EPIC（地球多色成像相机）拍摄的一张图像显示，该盆地再次充满了强大的风暴。夏威夷附近的飓风诺洛和下加利福尼亚半岛附近的飓风波罗正以大风、风暴潮和大雨袭击陆地。在波罗两侧，热带风暴雷切尔和后热带气旋奥达利斯分别导致墨西哥海岸和美国西南部的局势变得危险。
Hurricane Polo (below) made landfall in Baja California Sur around 11 p.m. local time on September 28 (06:00 Universal Time on September 29). Before encountering land, the storm had undergone extreme rapid intensification while churning over the unusually warm ocean surface, catapulting to category 5 status on September 22. Polo waned in intensity on its approach to the coast and likely made landfall as a category 2 storm, according to the National Hurricane Center (NHC).
飓风“波罗”（下图）于晚上 11 点左右在南下加利福尼亚州登陆。当地时间 9 月 28 日（世界时间 9 月 29 日 06:00）。在接触陆地之前，风暴在异常温暖的海洋表面翻滚时经历了极其迅速的增强，并于 9 月 22 日跃升至 5 级风暴。根据国家飓风中心 (NHC) 的数据，波罗在接近海岸时强度减弱，很可能以 2 级风暴登陆。
Polo then continued across the peninsula and the Gulf of California and made a second landfall , near Guaymas, as a further weakened system around midday on September 29. The NHC warned of dangerous winds and storm surge, as well as heavy rains capable of triggering flooding and mudslides in parts of Baja California Sur and Sonora.
随后，波罗继续穿越半岛和加利福尼亚湾，并在 9 月 29 日中午左右在瓜伊马斯附近第二次登陆，当时系统进一步减弱。国家飓风中心警告说，南下加利福尼亚州和索诺拉州部分地区可能会出现危险的大风和风暴潮，以及可能引发洪水和泥石流的暴雨。
The hurricane’s effects were expected to be even more widespread. Polo and its remnants, combined with moisture from Post-Tropical Cyclone Odalys, were likely to push over the southwestern U.S. and southern Plains over several days, forecasters said , fueling yet more heavy rain and flood risk. Next in the train of storms, Tropical Storm Rachel was tracking parallel to the southwest Mexico coast, where the NHC forecast strong winds and dangerous surf and rip current conditions.
飓风的影响预计会更加广泛。预报员表示，波罗及其残余物，再加上热带气旋奥达利带来的湿气，可能会在几天内席卷美国西南部和南部平原，从而加剧更多的暴雨和洪水风险。接下来的风暴中，热带风暴雷切尔平行于墨西哥西南海岸移动，国家飓风中心预报那里将出现强风以及危险的海浪和离岸流状况。
Meanwhile, the third hurricane of the season to pass close to Hawaii was delivering yet another deluge to the islands. Hurricane Nolo , though it did not make landfall, dropped more than 12 inches (30 centimeters) of rain on parts of Maui and the Island of Hawaiʻi. The storm flooded roads, toppled trees, and triggered landslides, according to news reports , but the Island of Hawaiʻi was spared some of the more severe effects wrought by Hurricane Lala in mid-August.
与此同时，本季第三场飓风经过夏威夷附近，给群岛带来了另一场洪水。飓风诺洛虽然没有登陆，但给毛伊岛和夏威夷岛部分地区带来了超过 12 英寸（30 厘米）的降雨。据新闻报道，风暴淹没了道路、倒塌了树木并引发了山体滑坡，但夏威夷岛并未遭受 8 月中旬飓风拉拉造成的一些更严重的影响。
As of September 28, the accumulated cyclone energy in the Northeast Pacific was more than twice the norm , according to data from Colorado State University . Scientists expect an increase in tropical cyclone activity in this ocean basin during an El Niño , which has been underway since June. Warm water in the equatorial Pacific and low wind shear in the region, both typical El Niño patterns, encourage tropical storms to develop and strengthen.
科罗拉多州立大学的数据显示，截至9月28日，东北太平洋累积的气旋能量是正常水平的两倍多。科学家预计，自六月以来厄尔尼诺现象期间，该洋盆的热带气旋活动将会增加。赤道太平洋的温暖海水和该地区的低风切变都是典型的厄尔尼诺现象，促使热带风暴发展和加强。
The NASA Disasters Program , in coordination with FEMA, is supporting the State of Hawaii’s response to Hurricane Nolo. The team will be posting maps and data products on its open-access mapping portal as new information becomes available.
美国国家航空航天局 (NASA) 灾难计划与联邦应急管理局 (FEMA) 合作，支持夏威夷州应对诺洛飓风。随着新信息的出现，该团队将在其开放访问地图门户上发布地图和数据产品。
