Tropical Cyclone (Hurricane) Basics & the 1-2-3 Rule for Avoidance Workshop ($65.00)

  • This seminar/workshop will discuss the basics for hurricanes & their impacts in the Gulf of Mexico, the North Atlantic &the Eastern North Pacific Oceans (Mexican West Coast), & sometimes Hawaii. Tropical Cyclones are different in size & dynamics than their middle latitude cousins (both provide their challenges to all boaters).
  • There will be an overview of Tropical Cyclone basics & their uniqueness as there are significantly different than most low pressure systems that dominate the planet in size, shape & the sensitive environment necessary for them to form, intensify, & maintain themselves, literally day by day if not hours at a time.
  • The Gulf of Mexico & North Atlantic & Tropical North Eastern Pacific Oceans are not limitless.
  • There are also hostile environments that these tropical weather systems encounter frequently, whether transiting over cooler waters or the entertainment of drier air, moving over land, & experiencing strong winds aloft.
  • Sometimes there is a transformation from tropical to extra-tropical (non-tropical) that sometimes results in a new more powerful storm system.
  • There will be an overview of Tropical Cyclone impacts on the coastal and nearby land interface where boats are frequently at if not sailing at sea (e.g. marinas & anchorages)
  • More importantly for boaters, the lead time for avoidance & strategies will be different in in time & space over open high seas waters than over the coastal areas.
  • Thus we introduce the 1-2-3 Rule for avoidance, concentrating on the 34 knot wind radii.
  • We will also breakdown the Tropical Cyclone Message (TCM) for interpretation, clarity, & application. The Hurricane Season in the Eastern North Pacific (begins May15th) is earlier that the North Atlantic (began June 1st) … both end 30th of November).

The hands on portion of this workshop is a practical exercise that will include:

  • Interpreting the advisory message issued every 6 hours known as the Tropical Cyclone Message (TCM) & constructing a “Danger Area to Avoid”
  • A practice walk-through exercise, applying the 1-2-3 Rule for the Gulf of Mexico & Caribbean Sea.

The environmental conditions that are necessary for tropical weather systems’ development & behavior are VERY different from those of middle latitude (30-60 degrees) origins as well, so this particular seminar will very well complement Lee Chesneau’s hour-long free seminar that follow…
