“伊萨亚斯”威胁墨西哥湾，新奥尔良发布飓风观察
据《什里夫波特时报》报道，随着热带风暴“伊萨亚斯”在墨西哥湾翻涌，美国国家气象局10月7日对新奥尔良发布飓风观察（hurricane watch），对路易斯安那州海岸发布热带风暴观察。
据报道，飓风观察意味着观察区内可能出现飓风条件——持续风速每小时74英里或以上，通常在48小时内。气象部门预计“伊萨亚斯”在穿越温暖的墨西哥湾水域过程中增强，可能在数日内在北墨西哥湾沿岸某处登陆。
路易斯安那州应急官员敦促居民检查飓风预案，储备食品、饮用水与药品，固定户外物品并持续关注官方预报。该州沿海各堂区仍在从本季早些时候的风暴中恢复，已开始预防性准备：清理排水渠、测试新奥尔良堤防系统的水泵、部署救援设备。
州长杰夫·兰德里（Jeff Landry）办公室表示，州应急行动中心正全天候监测风暴。在路易斯安那州，飓风的记忆刻骨铭心，官员强调居民不应等到警告发布才开始准备。
气象部门警告，即使直接登陆区以外的地区也可能遭遇强降雨与龙卷风——热带系统常在远离中心的地方制造恶劣天气。随着风暴逼近，观察预计将升级为警告。
Hurricane Watch Issued for New Orleans as Tropical Storm Isaias Threatens Gulf
NEW ORLEANS — The National Weather Service on Oct. 7 issued a hurricane watch for New Orleans and a tropical storm watch for the Louisiana coast as Tropical Storm Isaias churned across the Gulf of Mexico, the Shreveport Times reported.
A hurricane watch means hurricane conditions — sustained winds of 74 mph or higher — are possible within the watch area, typically within 48 hours. Forecasters said Isaias was expected to strengthen as it moved over warm Gulf waters, with landfall possible within days somewhere along the northern Gulf Coast.
Louisiana emergency officials urged residents to review hurricane plans, stock food, water and medications, secure outdoor items and stay tuned to official forecasts. The state's coastal parishes, still recovering from earlier storms this season, began precautionary preparations: clearing drainage canals, testing pumps in New Orleans' levee system and staging rescue equipment.
Gov. Jeff Landry's office said the state emergency operations center was monitoring the storm around the clock. Memories of past hurricanes run deep in Louisiana, and officials stressed that residents should not wait until a warning is issued to begin preparing.
Forecasters warned that even areas outside the direct landfall zone could see heavy rainfall and tornadoes, as tropical systems often produce severe weather far from their centers. The watch was expected to be upgraded to a warning as the storm drew closer.
