OR B) the wind is blowing TOWARDS the WSW at 15 to 25 mph?

 Feb 18, 2006, 02:54 PM Stay in it!!!! Riverside, California, United States Joined Aug 2004 5,076 Posts SW means from the south and west combined. WSW means that it has a little more of a westerly component.

 Feb 18, 2006, 04:29 PM Registered User Lakewood, Colorado Joined Aug 2002 33,101 Posts Of course, just to confuse the issue a little, when you look at wind barbs They "point" in the direction that the wind is coming from. My brain immediately looks at the pointy end of the barb and thinks SW, but they really mean that it's pointing from the origin to the NE. In this case that barb is indicating a NE wind, meaning the wind is coming from the NE. ian

 Feb 18, 2006, 08:20 PM Throw Caution to the Wind Grand Junction, Colorado Joined Feb 2004 2,652 Posts I like the good old fashioned weather charts. Felt more like I knew what the big picture weather was doing better when I could look at this: http://www.prh.noaa.gov/hnl/graphics/npac.gif Worked well when I was in Hawaii. But I can't seem to track down that kind of map for the mainland/western US. Anyone know of a location? Feels like I've stumbled all over the page here: http://www.crh.noaa.gov/ifps/MapClic...te=CO&site=GJT and http://www.crh.noaa.gov/product.php?...M&issuedby=gjt but can't find that kind of thing. Did recently find some cool pages for a multitude of weather stations all over the viscinity that could come in handy for the area wind. Sweet! This under ROMAN Weather Observations: http://raws.wrh.noaa.gov/roman/cwa/GJT_frame.html Can click on any of the tiny red pluses for current info and last 24 hours. Maybe this is old news, but it's new to me!

 Feb 18, 2006, 08:46 PM Registered User Seattle, WA Joined Aug 2005 692 Posts http://www.rap.ucar.edu/weather/info..._windbarb.html For the record, a simple conversion factor is to take knots and multiply by 1.15 (or 1.2 if you're lazy) to get the miles-per-hour strength of a wind. --Noel Last edited by NWade; Feb 18, 2006 at 08:51 PM.
