Fish storm warning for western subtropical Atlantic

Sunday 13th August 2017

Late last night, the National Hurricane Centre upgraded Disturbance Twenty Six to Tropical Depression Eight. Now centred around 500 miles south west of Bermuda, this is expected to develop into a tropical storm soon. This is not expected to maintain strength for more than a couple of days as latitudes to the north have wind shear and cooler water. This is moving just a tad west of north but will veer to the north east tomorrow to head away from both US and Canadian eastern seaboards, passing well to the west and north of Bahamas. For those at sea, who are the only ones likely to be affected, this is currently producing maximum sustained winds of 30 to 40 knots but freshening. Expect a maximum predicted hurricane severity rating of 5 out of a possible 50 (2 for size and 3 for intensity) with a tropical storm strength windfield radius of some 180 miles. A short lived but potentially vicious little fish storm.

Disturbance Thirty is two day's steaming west of the Cape Verde Islands, westbound at 15 knots. As things stand, this is expected to track west to west-nor'west over the next 5 days and in the long term, may curve away from the Caribbean although a little early to be certain. There is a question mark around this merging with a new low pressure cell - Disturbance Thirty One - which is a day and a half astern and gaining fast. Early days.

Batten down in the western subtropical Atlantic.
