• Sailing is all about the Weather.

    Big into the exploration of Atlantic Hurricanes since Katrina came uninvited into his world, James (Jim) Gurley (JamesG161) has followed every Tropical Storm birthed in Atlantic, Gulf and Caribbean waters since. Being a boater, he knows that we often need more time to prepare than we get from the TV weather folk. Jim relies on the science of storm development to share early warning info with friends and fellow boaters.

    Early in 2018, Jim and John Shepard, (JSSailem) started to chat about the weather data available. John asked Jim to help forecast Pacific NW storms, and this morphed into discussions on weather forecasting.

    For John, sailing in the PNW is sometimes hit and miss. One day is ugly, then a string of beautiful days but no wind, followed by a series of blue-sky days and 12 knot breezes. Being ready for those great sailing days means you need to look to the Pacific Ocean and what is brewing. John has been into Pacific NW Weather since the 1970’s when his first PNW November storm hit bringing more than 40 days and 40 nights of continual rain.

    Together we want to share information, new APPs, safety, and thoughts about letting the weather help you. Identify some of the resources for sailors and help prepare you for your next sailboat outing.

    It is far better to go out on the water knowing what to expect in weather terms, than to be out on the water and see dark ominous clouds suddenly appear, unprepared.

GNSS (a bit) in trouble

Sure James and I are into Hurricane weather patterns.

We are also Sun followers. Our friend in the sky... has been burping some negative magnetism. I know what can a burp mean to us here on earth.

The simple answer is screw up our electromagnetic dependent systems. I.E. GPS signals. On the 7th of November a burp put the GNSS systems which enable us in so many ways in "a bit" of trouble.
The "Bit of Trouble" they are referring to is the landing systems used in Canada and the US to bring planes in for a safe landing in marginal/inclement weather.

Since the GNSS systems clocks were disrupted, they were not providing our boats with accurate positional data. You may have experienced this "disruption".

It is no wonder to me that the tribes of primitives recognized the importance of the sun and were alarmed when it looked like the sun was not happy.

Happy Sun... Happy Life.
