预报员警告称，风暴可能产生破坏性风力和致命洪水。飓风西蒙周六在墨西哥太平洋海岸增强为强大的四级风暴，随着其逼近登陆，威胁着破坏性风力、风暴潮以及可能致命的洪水。
Forecasters warn storm could produce destructive winds, deadly flooding Hurricane Simon strengthened into a powerful Category 4 storm off Mexico's Pacific coast on Saturday, threatening destructive winds, storm surges and potentially deadly flooding as it approaches landfall.
美国国家飓风中心（NHC）表示，周六上午，西蒙位于曼萨尼约西南偏南约185公里处，伴随最大持续风速达每小时240公里，正向北移动。
The U.S. National Hurricane Center (NHC) said Simon was located about 185 kilometres south-southwest of Manzanillo on Saturday morning, packing maximum sustained winds of 240 km/h as it moved northward.
NHC称，西蒙预计将在周六晚间或周日早间以大型飓风的形式接近墨西哥西中部海岸，登陆前仍有可能进一步增强。
Simon is expected to approach the west-central coast of Mexico as a major hurricane late Saturday or early Sunday, and some additional strengthening remains possible before landfall, the NHC said.
墨西哥太平洋海岸波多黎各瓦尔塔海滨度假村以南的部分地区已发布飓风警报，包括曼萨尼约地区——墨西哥最大的太平洋港口。拉萨罗·卡德纳斯以南更远地区则发布了热带风暴警戒。
A hurricane warning was in effect for portions of Mexico's Pacific coast south of the beach resort of Puerto Vallarta, including the area around Manzanillo, Mexico's largest Pacific port. A tropical storm watch was in effect farther south toward Lázaro Cárdenas.
NHC敦促警报区内的居民——这也包括离岸的玛丽亚群岛群岛——加紧准备，以保护生命和财产。
The NHC urged residents in the warning area, which also includes the Islas Marías archipelago offshore, to rush preparations to protect life and property.

“强风可能损坏房屋和企业，而洪水和泥石流可能冲毁道路，使应急人员难以到达某些社区。即使风暴过去后，停电和基础设施受损也可能使恢复工作变得艰难。”
"Strong winds could damage homes and businesses, while flooding and mudslides could wash out roads and make it difficult for emergency crews to reach some communities. Even after the storm passes, power outages and damaged infrastructure could make recovery challenging."
墨西哥当局警告称，格雷罗州、米却肯州、科利马州和哈利斯科州预计将出现强降雨。
Mexican authorities warned that heavy rainfall was expected in the states of Guerrero, Michoacán, Colima and Jalisco.
美国国家飓风中心表示，西蒙预计将在周日之前为墨西哥西南部部分地区带来10至20英寸（25至51厘米）的降雨，米却肯州、科利马州和哈利斯科州部分地区可能出现局部高达30英寸（76厘米）的降雨量。这些降雨可能引发危及生命的洪水和泥石流，尤其在山区风险更高。
The NHC said Simon was expected to produce 10 to 20 inches (25 to 51 centimetres) of rain across portions of southwestern Mexico through Sunday, with isolated totals of up to 30 inches (76 centimetres) possible in parts of Michoacan, Colima and Jalisco. The rainfall could trigger life-threatening flooding and mudslides, especially in mountainous areas.
美国国家飓风中心表示，风暴潮预计将在风暴中心登陆附近及其以东的海岸出现，伴随大型且具破坏性的海浪。西蒙产生的涌浪预计将在未来几天影响墨西哥西南部和西中部海岸部分地区，导致危险的冲浪和激流条件。
A storm surge is expected along the coast near and to the east of where the centre makes landfall, accompanied by large and destructive waves, the NHC said. Swells generated by Simon are expected to affect portions of Mexico's southwestern and west-central coast over the coming days, creating dangerous surf and rip current conditions.
西蒙预计将在周日接近或刚刚进入墨西哥西中部太平洋海岸内陆地区。
Simon is forecast to be near or just inland of Mexico's west-central Pacific coast on Sunday.
