路透9月24日電——美國國家颶風中心（NHC）週四在公告中表示，「極其強大」的颶風波羅（Hurricane Polo）沿墨西哥本土近海緩慢向西北移動，巨浪與大雨襲擊墨西哥西南部。Sept 24 (Reuters) - Heavy surf and rain lashed southwestern Mexico as "extremely powerful" Hurricane Polo crawls northwest offshore the mainland, the US National Hurricane Center (NHC) said in a bulletin on Thursday.

波羅最大持續風速接近每小時155英里（每小時250公里），最近被歸類為4級風暴，較先前達到的薩菲爾-辛普森颶風等級最高級別5級低一級。With maximum sustained winds near 155 miles per hour (250 kph) Polo has been classified last as a Category 4 storm, a notch down from level 5, the highest level on the Saffir-Simpson scale, which it had previously reached.

NHC持續調整對這場風暴強度的評估，並表示短期內可能稍微增強，預計未來幾天仍將維持大型颶風強度。As the NHC keeps adjusting the storm's force, it said it could see some near-term strengthening and is expected to remain a major hurricane for the next few days.

私人天氣預報機構AccuWeather預估，波羅將在週日晚間稍晚至週一登陸，屆時威力會略為減弱，並在穿越下加利福尼亞半島、行經聖盧卡斯角以北地區時達到2級颶風強度；當地政府已開始限制民眾進入海灘，並關閉當地港口。AccuWeather, a private forecaster, expected Polo to make landfall late Sunday night into Monday, to lose some steam and to reach a Category 2 hurricane as it tracks across the Baja California peninsula north of Cabo San Lucas, where local authorities have already begun restricting beach access and closing the local harbor.

NHC表示，波羅外圍雨帶正延伸至陸地並帶來豪雨。NHC說，墨西哥西南部沿岸很可能已出現熱帶風暴強度的風勢。The NHC said that Polo's outer rainbands are spreading onshore and producing heavy rains. Tropical-storm-force winds are likely occurring along the coast of southwestern Mexico, it said.

波羅的颶風強度風場自中心向外延伸最遠達40英里（65公里），熱帶風暴強度風場則向外延伸最遠達125英里（205公里）。Polo's hurricane-force winds extend outward up to 40 miles (65 km) from the center and tropical-storm-force winds extend outward up to 125 miles (205 km).

墨西哥米卻肯州、科利馬州、哈利斯科州北部與南部，以及納亞里特州的沿海地區，預計還會出現2至4英寸（50.8至101.6毫米）的累積降雨量，局部最高可達6英寸。Additional rainfall totals of 2 inches to 4 inches (50.8 mm to 101.6 mm), with isolated maximum totals up to 6 inches, are expected across across coastal portions of the Mexican states of Michoacan, Colima, northern and southern Jalisco, and Nayarit.

NHC表示：「這些湧浪可能造成危及生命的巨浪、離岸流與沿海淹水。」"These swells are likely to cause life-threatening surf, rip currents, and coastal flooding," said the NHC.

AccuWeather颶風專家尼可拉斯・阿曼表示，如果這場颶風維持預期路徑，部分降雨與水氣可能被帶進德州。AccuWeather hurricane expert Nicholas Arman said that if the hurricane stays on the expected track, some rain and moisture can be pulled into Texas.

他說：「這是典型的聖嬰現象影響，太平洋強烈的熱帶系統發展，最終會把水氣推向美國西南部。」“This is textbook El Niño impacts where the strong tropical development in the Pacific ultimately pushes moisture into the southwestern US,” he said

有多少降雨與水氣會抵達德州，取決於這場風暴能否穿越馬德雷山脈。這是一個大型山脈系統，從墨西哥西北部與西部至加利福尼亞灣沿線，呈西北—東南走向延伸。How much rain and moisture reaches Texas depends on the storm’s ability to cross the Sierra Madre mountains, a major mountain range system which runs northwest–southeast through northwestern and western Mexico, and along the Gulf of California.

阿曼補充說：「馬德雷山脈對有組織的系統常常像起司刨刀一樣，會把它撕碎，讓任何有組織的熱帶系統無法維持完整。」“The Sierra Madre often act like a cheese grater to an organized system, shredding it apart and preventing any organized tropical feature from staying together,” Arman added.
