Here is another tip for the MM5 forecast, making the model loops run every hour instead of every 3 hours. It is borrowed from the NW-Windsurf group courtesy of Chuck D. Even though I have used the MM5 forecast for many, many years, I didn't know this trick...........until yesterday.
Ivo


The model runs kick off every 12 hours. For the model run in the example below, the format is:

2014092500 -> 2014 09 25 00

2014: year
09: Sept
25: 25th
00: 0000 UTC (midnight)

Subtracting 12 hours goes back to 1200 UTC on Sept 24th (the day before), or 2014 09 24 12 (2014092412). That's the text you throw in after the "+" in the URL to quickly access the previous (completed) model run.

The other way is to just access the whole list of model runs from the GFS-WRF home page, To your question, the the dates on the left are the every-12-hour model runs. If the most current domain run isn't complete (and the 1.3km grid ones often aren't since they're run last), just pick the next date down. You can then scroll to the bottom of that run's page and then select your favorite 1.3km product (e.g. "1 1/3 km Surface - Puget Sound 10m Wind Speed", "LOOP").

You'll have to do one more trick here to get full resolution. The default URL will end in a "3", which represents the number of hours between the displayed frames. Change it to a "1" to get every hour.

"Port Townsend Triangle: the area with\in the triangle formed by Port Townsend, to Oak Bay to Kayak Point blows first and in the same manner as Double Bluff.
This should be of no surprise considering DB is inside the Triangle.

Cool. I actually have that site book marked, but I didn't really know how to use it.

Timing??? - if the gradients are right, what does that mean?
- Does it mean it will blow tomorrow? Today? Now? for the next hour, day?

The wind senors tell me if it is blowing now.

For Belfair, I know it is going if Shelton and Bremerton airport sensors are over 10.
Typically, Shelton will be reading high like 20 or 24 and Bremerton will be lower, like 10 or 15.
Belfair will be somewhere in between or closer to Shelton.

Forecasting Belfair, I like to see the storm system coming from the W, WSW or even WNW.
G-Spot will be showing W winds in the straights and coast and even NW in the very north Puget Sound. The wind will wrap around the Olympics and blast at Belfair.
Many times there will be convergence in Seattle.
If the storm system is coming too far from the South, the wind will miss Belfair. Places like Double Bluff will get good SE.
Belfair is supposed to get the "clearing wind" after that storm blows through, but that doesn't always happen.
There were a ton of times last year when the system would bring great wind up at Double Bluff and it would not blow at Belfair or South Sound.

At Fox Island, we get very similar wind to Purdy and Belfair - so I have been watching it very closely - watching you guys post about Double Bluff being awesome 9m while we have no wind down here.

On the typical SW, Belfair blows harder than Purdy, which blows a bit harder than Fox Island. When it is really blowing, it is good at all 3 spots.
When the weather system isn't super powerful, it is typically much better at Belfair than it is at Purdy or Fox Island.

Excellent thread! Let's make this standard kind of dialogue on this forum versus childish bickering. Thanks Stephen for the positive leadership.

OK, it's been a while since I checked and tuned up my bar and lines.Find a location where you can run your lines full length with your kite attachment ends near a post or other fixed object to be able to attach a line with a knot / carabineer or any other way of attaching your lines . Run out and sort out your lines as you would be setting up for attaching to your kite , all while checking for wear on the lines and chicken loop line too, also check your bar for any corrosion or cracks. Next step to checking your lines is to hook up the inside flying lines to the fixed object and make sure they are equal length at the point they connect to each other, if there the same length great if not , you can pull to stretch the shorter one to equal them out , if your flying a 5line kite make sure all three are the same before moving on to the next step . So then you attach you outside steering lines to the fixed object so that all lines attach to the same point. Go to the bar , let the sheeter cleat out all the way to max power, then tension the lines holding just the bar , see if all the lines are equal in length, most manufactures are tuning the kites this way, make adjustments or stretch to balance out the bar along with equalling the front lines and the steering lines. This is also a great time to replace questionable lines . Be a good time to check kite bridles and pulleys too. Good old preventative maintenance could save you a session and be much safer! Hope this helps

Thank You Stephen,
I the past I have used West Marine's "Amsteel" product for replacing the De-power/Sheeter fat cord. But in the past few years kite mfgs have added in stitching and complications to make this DIY effort a pain, so lately I just spend more $ at USurf. Any advise? Sound's like a project for PMCD.

Save the grip on your bar: I've noticed over the years that the grip on my bar was always coming apart or getting damaged. Well, I just bought a new bar and noticed their packaging. Made me realize that the wear was coming from the quick release being folded back against the bar and digging into the grip. I made a sleeve out of bubble wrap and duct tape. Seems to be saving some wear and tear on the bar. So I've got that going for me. ;)
