Planned an offshore overnight from St Augustine to Ft Pierce. A 34 hour trip. A week prior I began checking weather. NOAA and Passage Weather were in agreement, westerly winds 10 to 15 occassionaly 15 to 20. Seas 3 to 6. Near perfect conditions. As a thought I looked at Windytv forecast. They were forecasting winds in the mid 40 range. Since that was so far off of everyone else I disregarded their forecast totally. Two hours after clearing the inlet winds piped up to 35kts and eventually to 45 kts. Max gust recorded by the anemometer was 50.4 kts. We remained in those conditions for 30 hrs. Needless to say it was quite a ride. I will be paying a lot more attention to windytv.com from now on. And BTW don't let anyone tell you that Hunters can't handle bad weather off shore. The boat a 37.5 did just fine.
