“What the f*ck was THAT!?”In not so many words, that was my message to WRI later that day. If nothing else, I was curious. There’s no way that was a typical tropical squall, I thought. The violence of that had to come from a different mechanism.To: Captain, IsbjornPrepared: January 30 17:33zFM: WEATHER ROUTING INC. (WRI)A strong trough has developed and is extending SW’ward from a mid-level low from 20N/37W SW’ward to 14N/42W and will slowly lift to the northeast through the 01st. The associated trough will lift northeast through the 01st. Latest satellite imagery shows numerous squalls have developed ahead of the trough though the worst of these squalls are situated north of 15-30N. Immediately behind the cold front, winds will quickly increase out of the N-NNE of 20-25kts with gusts to 30kts this evening before lowering to NE-ENE 17-22kts overnight tonight. However if any of the squalls spread farther south, winds could become locally higher of 30-35kts near and just immediately behind the trough. Best Regards, Weather Routing Inc. (WRI)Okay then. What the GRIBs had missed, and what I had failed to recognize (because the signs were there), was this frontal boundary which had caught us nearly with full sail up. Sure enough, just as WRI predicted, the wind built overnight last night to 30-35 from the NNE, the breeze we’re sailing on now. The GFS model, which I downloaded just last night before bed, indicates we ought to be sailing in 11 knots from the SE…
