Storm!

The remnants of tropical storm Leslie are approaching the Hebrides, and we are on warning for severe gales, possibly stormforce winds this evening. The weather at our latitudes is governed by differences in temperature, and Leslie swept up from Bermuda last weekend, carrying a large amount of warm, moist, tropical air. Having met with a frontal boundary to much colder and drier air over eastern Canada on Monday, the result is a deep depression to the south of Iceland. A tight pressure gradient to its south will push winds to force 9-10, and cause disruption on our ferries. The run between Oban and the southern isles is already cancelled, as this route is exposed to the southwesterly wind and swells. Other ferries are on warning for possible cancellation, including our link to Ullapool; today's evening crossing from Ullapool could be cancelled. I'm closely monitoring the Calmac website for updates.
