Summer SuperFog

 Coal Train Update

     Last night (Thursday) Professor Dan Jaffe, myself, and some students took observations of particle levels at Richmond Beach Park in Shoreline on the bridge over the track.   The goal was to determine what was coming off the coal trains.  We sampled several freight trains and one coal trains.  A video showing this fun is found at: http://www.king5.com/video?id=163980306&sec=549122

Thanks so much for those providing information about coal train passage.  We are going to do this multiple times and will let you know what we find.  For those living near the tracks, how often are there trains in the morning?

It is relatively unusual, but we have late July dense fog over the south Sound...dense enough that it delaying some flights at Sea-Tac.   Here are the latest observations at the airport. Quarter-mile visibility on the runway. 

Here is the latest Sea-Tac cam shots:

Says everything, right?  Or the view from the KING-5 tower cam on Queen Anne Hill.   Poetic.

Even the roadways are being affected...here is I5 near S 200th St.

You can see the low clouds and fog from the latest visible satellite image.   The clouds are covering the cost and much of the lowlands...head up and you are out of it....or just go north of Seattle.

The low clouds and fog will rapidly burn off this morning.

By the way, if you are really into low clouds, the National Weather Service has a marvelous new web page showing cams along the coast (http://www.wrh.noaa.gov/sew/bars_mover.php).  As you mouse-over locations you see the cams along the coast.
You can get you fill of low clouds from the comfort of your home.
