飓风Vance在墨西哥太平洋近海保持110英里时速：国家飓风中心称今晚起逐渐减弱，沿岸将现危险巨浪
美国国家飓风中心（National Hurricane Center，NHC）10月24日凌晨发布的第12号公告显示，飓风 Vance 在墨西哥太平洋近海保持强度，最大持续风速约110英里每小时（约175公里每小时），为二级飓风。该中心表示，Vance 今天白天强度可能略有波动，随后将从今晚开始逐渐减弱，并持续至周日。（GSM 据美联社报道）
公告称，美国中部时间10月24日凌晨3时（协调世界时9时），Vance 的中心位于北纬12.4度、西经102.8度，距墨西哥 Acapulco 西南偏南约590公里，距 Manzanillo 东南偏南约750公里，正以约每小时11公里的速度向北偏西北方向移动，预计这一走向将持续整个周末。Vance 的最低中心气压为965毫巴；飓风级大风从中心向外延伸约45公里，热带风暴级大风延伸约240公里。目前墨西哥沿岸没有生效的飓风或热带风暴观察预警，国家飓风中心表示，墨西哥西南部沿岸地区应密切关注 Vance 的动向。
在陆上影响方面，国家飓风中心表示，Vance 掀起的涌浪将在本周末影响墨西哥南部与西南部沿岸，并持续至下周，这些涌浪可能造成危及生命的拍岸浪与离岸流状况，沿岸居民与游客应查阅当地气象部门的产品。
Vance 于10月21日在东太平洋形成，本周快速增强：据美联社报道，它在周五已加强为二级飓风，一度接近三级强飓风的门槛。美联社指出，今年太平洋飓风季异常活跃，夏威夷与墨西哥近海的风暴接连生成；若 Vance 达到三级，它将成为本季连续第七个强飓风，此前的六个为 Nolo、Odalys、Polo、Rachel、Simon 与 Trudy。国家飓风中心预计 Vance 将在移动中逐渐减弱，是否登陆墨西哥西海岸仍取决于其后续路径。
Hurricane Vance Holds at 110 Mph Off Mexico's Pacific Coast as Hurricane Center Warns of Life-Threatening Surf
Hurricane Vance held its strength off Mexico's Pacific coast early on October 24, with maximum sustained winds near 110 mph (175 kph), a Category 2 hurricane, according to Advisory Number 12 issued by the U.S. National Hurricane Center (NHC). The center said some fluctuations in intensity were possible during the day on Saturday, followed by a gradual weakening trend beginning Saturday night and continuing through Sunday.

At 3 a.m. CDT (0900 UTC) on October 24, the center of Vance was located near latitude 12.4 North and longitude 102.8 West, about 590 kilometers (365 miles) south-southwest of Acapulco, Mexico, and about 750 kilometers (465 miles) south-southeast of Manzanillo, the advisory said. Vance was moving toward the north-northwest near 11 kph (7 mph), and that motion was expected to continue through the weekend. Its minimum central pressure was 965 millibars. Hurricane-force winds extended outward up to 45 kilometers (30 miles) from the center, and tropical-storm-force winds extended up to 240 kilometers (150 miles). No coastal watches or warnings were in effect, and the NHC said interests along the southwestern coast of Mexico should monitor Vance's progress.
On hazards affecting land, the NHC said swells generated by Vance would affect portions of the coast of southern and southwestern Mexico this weekend and continue into next week, and that those swells were likely to cause life-threatening surf and rip current conditions.
Vance formed in the eastern Pacific on October 21 and strengthened rapidly this week. According to The Associated Press, it reached Category 2 strength on Friday and neared major-hurricane strength. The AP noted that it has been an intense Pacific hurricane season, with storms spawning in succession near Hawaii and Mexico; if Vance were to reach Category 3, it would be the season's seventh major hurricane in a row, following Nolo, Odalys, Polo, Rachel, Simon and Trudy. The NHC expects Vance to weaken gradually as it moves, and whether it makes landfall on Mexico's west coast will depend on its track in the coming days.
