• 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.

There is Tropical Wave charts for several days.

The models seem on the same course.

TABD is best for 96 Hours.

This is GFS model forecast for 10 day from today.

This will be a major storm nearing the East Coast. The next 5 days will tell us more.

Although at 12 days out the forecast probably shows the one thing that won’t happen.
One must remember. These are future projections of a mathematical historical model with dynamic fluid events happening over the period identified. Much beyond 3-5 days the reliability of the model begins to vanish.

But it is fun to… What if?

This is the reason it will be a Major Storm.

Hurricane Fuel or Stored Solar HEAT.

Normally we show just the top ±10 feet of HEAT, but 3 Satellites combined can estimate how Deep that HEAT is stored.

I like this format better, to predict Storm Intensity. The 20°C or 68°F Isotherm.

Lee looks like really bad juju
Rick... If you are still in "Pt Judith" is way to early to be concerned about the sky falling over Rhode Island.

"Lee" is announced. It will be traveling over some of the same water that 95L traveled. It is starting in a similar position in the Atlantic. What it will be come is way to early to conjecture. We have really no idea of the "juju" it has or will develop. 10 days in the future this is what the upper level winds look like - dragging the storm east into the Central Atlantic.

It certainly bears watching and could become a problem. 5 days from now we will have a better opportunity to identify the risks.

Stay tuned. James and I are watching the development of the Atlantic storms. Always fun to have participants join in and help us focus attention on what is brooding out there.
THANK YOU.
It is the reason we devote our time to this Weather and Forecasting forum.

Here in Florida it's all about evacuation. You can't stay for a Cat 4 or above. Problem is you don't know in time to evacuate if the storm will be that intense or not. In this case the forecast it's a Cat 4 , less than 200 miles away. Pucker time! Maybe a time to drive to Sebring.
And thanks to the Hurricane Team for what insights they can give!

TS Lee should not Fear, Hurricane Margot will follow his Rear. :beer::beer:

The thought of a savior brings hope to many a weather watcher.
Too early to tell. The GFS and Euro models are not in agreement as to the path of LEE. I am working on some analysis this AM.

The upper level winds pic you posted last night, what actual level was that?
