• 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.

Isn't it kind of weird for a storm system to move westerly in that area?
Yes!

The key is the center of the Storm is over land.
Thus lack of Vorticity to pick up HEAT from the Gulf.

Making it a rain event. :clap:

On Florida's east coast we have been getting fairly heavy downpours over the last day or two. That is normal at this time of year.. What is unsual is that the cells are coming from the south. Normally they work their way over from the Gulf coast. The weather people said there is a stationary front over us and that was generating the t-showers.
But I'm guessing they are bands associated with the Low that is over land on the Gulf coast (93L). Is that so?

I've heard, I think on the radio, that on the east coast of Florida the afternoon thunderstorms occur as the sea breeze develops. That wind is said to lift the very humid gradient breeze from the Gulf side creating instability. Is that correct?
