Extreme weather upsets travel across Europe, US

FRANKFURT/OSLO/PORTLAND, Oregon — Heavy snow and freezing rain in parts of northern and central Europe grounded hundreds of flights and disrupted train travel on Wednesday, while an ice storm in the US Pacific Northwest turned roads and mountain highways treacherous.

Germany's massive Frankfurt airport canceled all flights in the early afternoon as jets could no longer be de-iced, but later resumed service with a limited capacity, a spokesperson said, adding that the situation remained uncertain.

The airport in the Norwegian capital, Oslo, also reopened but said it faced big delays that had left many passengers stranded.
