Subtropical storm ERNESTO under way

Thursday 16th August 2018

Disturbance Twenty Seven is now centred around 400 miles north-nor'east of the mouth of the Amazon, steaming due west at 14 knots. Aerial imagery shows a break in sand-laden air which may allow a short but unsustainable spell of development before it reaches the Lesser Antilles this coming weekend. By that time it is expected to be a weak trough of low pressure, capable of little more than producing enhanced shower and thunderstorm activity.

As anticipated, the National Hurricane centre upgraded Subtropical Depression Five to Subtropical Storm ERNESTO immediately after we posted yesterday's report. This is now centred about 625 miles south east of Newfoundland. ERNESTO is headed north-nor'east at 12 knots, producing storm force winds of up to 55 knots over a radius of almost 150 miles. This will develop a little more before it starts to accelerate and weaken over the next couple of days causing a couple of lumpy nights for sailors but well clear of land.

Stand by for stormy conditions across the north-west Atlantic, otherwise stand easy.
