飓风波洛在墨西哥太平洋沿岸迅速增强,已升级为5级飓风134。气象部门评价其增长速度"极其显著"1,并将其描述为"极其危险"3和"有史以来最强风暴之一"234。风速已达到近180英里/小时5,成为太平洋本季第三个最高级别飓风5。
根据美国国家海洋和大气管理局的预测,飓风波洛将沿墨西哥西南沿海移动但不直接登陆5。然而,该风暴仍可能产生生命威胁性洪水1,并带来暴雨、洪水和泥石流风险5。预计沿岸地区降雨量达6英寸,部分地区可能达8英寸5。墨西哥总统克劳迪亚·塞恩鲍姆表示飓风不会直接登陆,但警告太平洋沿岸居民保持警惕5。
飓风的快速增强与异常温暖的海水条件密切相关。9月19日中东太平洋海表温度比平均水平高3.05摄氏度,超过了2015年的纪录3.02摄氏度5。美国国家海洋和大气管理局称当前厄尔尼诺是有记录以来最强的5,为这场罕见的强烈风暴提供了充足的能量来源。
Hurricane Polo has rapidly strengthened into a rare Category 5 hurricane off Mexico's Pacific coast, with wind speeds reaching nearly 180 miles per hour 5. The storm has been characterized by meteorologists as "extremely dangerous" and described as "one of the strongest storms ever" 34. The hurricane's exceptional intensification has been attributed to unusually warm ocean waters associated with the El Niño phenomenon 1.
The National Oceanic and Atmospheric Administration projects that Polo will move along Mexico's southwestern coast without making direct landfall, though it poses significant hazards to the region 5. The storm is expected to produce life-threatening flooding, with anticipated rainfall of 6 inches across affected areas and up to 8 inches in some locations, along with associated risks of flash floods and mudslides 5. Mexico's President Claudia Sheinbaum stated the hurricane will not strike directly but urged residents along the Pacific coast to remain vigilant 5. Polo marks the third Category 5 hurricane of the current Pacific season 5.
The exceptional strength of this storm reflects record-breaking ocean conditions, with sea surface temperatures in the eastern Pacific on September 19 measuring 3.05 degrees Celsius above average—surpassing the previous 2015 record of 3.02 degrees Celsius 5. The National Oceanic and Atmospheric Administration has characterized the current El Niño event as the strongest on record 5.
