***This 55-minute free seminar begins with an important discussion of the marine oriented strong wind & small craft advisories, watches, & warnings system used by the Environment Canada & the U.S. National Weather Service’s (NWS) Ocean Prediction Center (OPC), National Hurricane Center (NHC) Tropical Analysis & Forecast Branch (TAFB), & the Honolulu Forecast Office (NWSFO HNL) marine program.
- There will be a detailed discussion of the universal station plot of surface weather observations from ships at sea, fixed moored buoys, & land stations that report sea level pressure, winds, & present weather conditions, the bases for the OPC’s Surface Analyses Pressure charts.
- There will also be an overview of the key synoptic scale surface pressure weather system’s symbols (e.g. low & high pressure) & their associated features (e.g., fronts, troughs & ridges, & squall lines, just to name a few), challenging boaters as to what they know versus what they not know about them.
***Attendees are strongly encouraged to enroll in the paid 3-hour “The Surface Pressure Chart Workshop” that follows, scheduled from xxx to xxx PM which will go into more in-depth detail on the variety of Surface Pressure Analyses & Forecast Charts & the specific weather conditions a boater can expect (e.g., clouds, precipitation, pressure & wind changes), along with Lee Chesneau’s hierarchy for marine weather prediction, vessel routing & decision making. See boat show schedule for further details.
