Malibu's Pacific Coast Highway, which just reopened after last month's devastating Palisades Fire, is closing again Tuesday due to concerns about potential mudslides, landslides and debris flows from a prolonged atmospheric river event.

The roadways are icy and slick for some parts of the area Thursday morning as a major winter storm moves through the Philadelphia region, sweeping from the Midwest to the Northeast. A Winter Weather Advisory went into effect for the Philadelphia region at 11 p.

An approaching system could bring up to 5 inches of snow and ice, and disrupt morning and afternoon travel before a flip to rain in some places.
