I think the first tropical wave of the season deserves a new thread, don't you?

Thanks. It seems WWD means Wind Wave Direction, or the direction in which (surface?) wind and waves are moving, as reported for example from a buoy like that displayed at http://www.ndbc.noaa.gov/station_page.php?station=42035. It seems WWD is recorded as being from 0 - 360 degrees and is reported as a compass point, e.g., SSW.
By comparing the movement of clouds visible in that area with the little red flags shown when the "HDW-low" box is clicked at http://www.ssd.noaa.gov/goes/east/watl/loop-vis.html, the buoys (and/or vessels I suppose) nearest that latitude and longitude seem to be indicating (??) that the low pressure is rotating in a counter-clockwise pattern. Beyond that I don't see much else to help me understand what "MOVING SLOWLY WWD" might be saying. Again, thanks.

Golly, there's even more hits for WWD, weather and westward! And yes forecasters definately use it that way. 
Clearly I should have paged further forward through the search results. But at least I found out where the little red flags come from (or at least perhaps one of them - most seem to be moving and some seem to be missing). Thanks!

Thanks for the wake up call! So... more or less on June 1, wind currents change to allow tropical waves to move further WWD. Because this one, or at least the convection associated with it, seems about to start moving northeast.

In addition to water tempaeratures is that why the Atlantic hurricane season officially begins in June?

The eastpac TWD have been kind of droll this weekend, with the discussion first separating the area to the east and west of a given longitude, then to the north and south of a given latitude, now this morning's separated into upper level and surface features. 
* * * * * * *
We have 90E. This morning's TWD was right on the money.
I started a new thread.
