• 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.

Interesting that the peaks in the Bahamas reconstruction both occur during the "Little Ice Age"

The Little Ice Age (LIA) was a period of regional cooling, particularly pronounced in the North Atlantic region,
The time period has been conventionally defined as extending from the 16th to the 19th centuries,[4][5][6] but some experts prefer an alternative timespan from about 1300[7] to about 1850.[8][9][10]

The frequency is one thing, the intensity is another. After spending month in the Abacos this spring and seeing the devastation that Dorian brought over 2 years prior, hurricanes in this area are not to be trifled with. A few years back the Exumas and Ragged Islands were equally devastated by a hurricane.

Very interesting. It appears that the hurricane activity coincided with the grand age of sailing. Between 1750 and 1850 were 100 years of sea power.

Ben Schmidt made this wonderful visualization of shipping from 1750-1850 using ship log data. It’s long, but worth watching. You can see the infamous Triangle Trade, the effect of the American Revolutionary War, the rise of British colonial sea power. If you watch the months as they role by you can see the timing of ships to avoid the storms of the time.
