野火正在摧毁西海岸部分地区的房屋建筑,空气也被严重污染。今天,美国EPA的空气质量监测网站将波特兰的空气列为“有害”,AQI(空气质量指数)从350-515以上不等。有关部门敦促居民待在室内避免吸入空气中的有害物质,预计周二的空气质量仍然会非常“不健康”。
与此同时,气象局今早对俄勒冈州北部海岸地区发布浓烟警报,能见度已经降低至50英尺。
据最新数据,数十场大火已经在10个州烧毁了超过460万英亩的土地。空气中的有害物质在吸入后会深入肺部甚至进入血液,患有肺部或心脏疾病的成人以及年龄较小的儿童都面临着更大的风险。
Whoa. Lots of fog and smoke, with much of it rather dense with low visibility. Many have reported only seeing as far as 50 feet in spots. Slow down, and use extra care while out and about. Conditions will slowly improve later this morning. #pdxtst #orwx #wawx pic.twitter.com/saWB3Ki1AA

One of our @NWS_IMET_OPS took this photo yesterday outside of Springfield, OR. Check out just how dense that fog really is! Today is similar with thick fog & smoke blanketing the area. We remind you all to please stay safe, stay well & turn to emergency managers for safety info. pic.twitter.com/xAPZNH09Ba
