A | MADRID -- Some 314 migrants arrived in Spain's Canary Islands in two boats early Monday, bringing to more than 1,600 the number of migrants to reach the islands since Friday, emergency services said.The service said one boat carrying 229 migrants was escorted to El Hierro island while another with 85 was taken to Tenerife . Of the boats that arrived over the weekend, one on Saturday was carrying 320 migrants. The state news agency EFE said it was the largest number in a single boat since human traffickers began to regularly use the Canary Island route in 1994. The previous record of 280 was recorded earlier this month.Most of the boats arrived at El Hierro, which has received several thousand migrants in recent weeks. The Canary Islands are located off the northwest coast of Africa.Most of the migrants come from sub-Saharan African countries and most of the boats depart from Senegal.Migrants arriving by boat in Spain spend up to 72 hours in police custody, for identification, then are moved into various reception or detention centers depending on their cases. Although some are deported, most apply for asylum and are taken to mainland Spain for their petitions to be studied.In the end, many are freed and ordered to leave Spain if they don’t get asylum.Spain’s Interior Ministry says nearly 23,500 migrants reached the Canary Islands by boat between Jan. 1 and Oct. 15. That’s a 90% increase from the same period last year.___Follow AP’s global migration coverage at https://apnews.com/hub/migration。

据路透社报道

报道称，气象预报员表示，风雨短暂停歇后，当地时间5月10日降雨又至，情况“令人担忧”。据美联社报道，巴西国家气象研究所当地时间10日发布公告称，周末降雨量可能超过15厘米，并可能加剧洪灾。

此前，自4月29日以来，南里奥格兰德州就遭遇暴雨袭击，连日暴雨引发洪水和山体滑坡等自然灾害。

南里奥格兰德州民防部门说，此次洪灾是该州历史上最严重的自然灾害。不少地区断水断电，共140多万人受到影响。在阿雷格里港，瓜伊巴河决堤，市内街道被淹，汽车站和飞机场均已停运。

此外，阿雷格里港和周边城镇近50万用户断电。

E | 巴西国家电网运营商ONS说，受暴雨影响，5座水电站及输电线路已关闭。除损毁重要基础设施外，暴雨和洪水还导致南里奥格兰德州不少农田被毁，一些牲畜死亡，大豆收成减少，多家肉类工厂停工。

国家气候中心气候服务首席专家周兵表示，巴西近期遭遇强降雨，主要是受到当地大气环流异常影响，但大气环流异常的重要推手是热带纬圈环流的转折与变化。尽管本次厄尔尼诺事件即将在5月结束，但与厄尔尼诺相关联的南方涛动指数已经出现了转折，向着有利于拉尼娜事件发展的状态变化，赤道信风加强、沃克环流加强，这些均为本次降雨过程“创造”了有利环境。

有关专家表示，气候变化导致此类事件发生的机率增加。早预警、早行动，提升灾害防御能力，才能更好地应对这些风险的发生。
