No rain expected this New Year’s Eve, but the weather isn’t good news if you have respiratory challenges – the National Weather Service has issued an air-stagnation advisory for Seattle and vicinity, in effect 10 pm Wednesday through 10 am Monday. This means, as the advisory notes, that “due to limited movement of an air mass across the advisory area, pollution will increase to dangerous levels.” No burn ban so far, but that could change (you can check here or on the WSB West Seattle Weather page). It’ll be colder than usual, too – highs in the 30s, lows in the 20s.
