Monday 4pm - Wind conditions with strong easterlies, "enhanced" by dense air, have been so favourable and powerful for Tom Dolan's anti-clockwise Round Ireland challenge that he has been able to downgrade the significance of favourable tides. Having breezed through the North Channel with insouciant style in the dark, at 16OO hours this (Monday) afternoon, he's 24 hours on his way and will soon be halfway across Donegal Bay at a
current average speed of between 9 and 11 knots, well within sight - were visibility better - of the northwest corner of Mayo.
Thereafter, progress south from Eagle Island, and particularly once Slyne Head is astern, will be increasingly dependent on the continuing eastward progress of our current dominant low-pressure system. Its centre is currently about 40 miles west of Shannon Mouth, but as it is part of a larger system, all of which is likely to become less clearly defined as Storm Ciaran approaches through Wednesday, Tom is acutely aware that things could get messy as he approaches the Blaskets, where the frequently confused sea state greatly increases the benefit of a good fair wind.
So far, it has all been done with an impressive flourish. But with every southward mile made good, the likelihood of a less favourable scenario increases, with the majestic coast of Kerry and West Cork being a major challenge in themselves. Thus, if the low-pressure sub-system slows in its eastward progress, it's even possible that he'll shape his course well to the west to find the more favourable winds chasing the depression.
