If you were in the ARC race and you pulled up a NOAA 24 hour wind/wave forecast that looked like this: http://weather.noaa.gov/pub/fax/PWEE89.TIFYou were around 19 N Lat and 43 W Long and headed for St. Lucia from the Canary Islands. Look carefully at the map at approx location 15 N lat and 50 W where the letters 'TROF' are found. You are basically headed that direction southwest by west. What do you make of the letters 'TROF' on the chart and what actions would you take?1) Assume that the guys at NOAA are drinking too much coffee and really want to build a FORT there and forget about it?2) Assume that this is shorthand for 'trough'; it really sounds the same phonetically, right? There might be some wind and weather with that so whoopie!3) Assume that this is shorthand for 'tropical formation' and take down the stern rail barbecue and a few other things?4) Do more research on NOAA shorthand symbols.
