DEBBY fading in North Atlantic

Thursday 9th August 2018

Satellite imagery indicates that tropical storm DEBBY is centred around 500 miles east-sou'east of Newfoundland and has weakened as it crosses cooler water. This is now barely discernible and will disappear as it sprints north-nor'east into north Atlantic murk.
Meanwhile, back in the convergence zone, Disturbance Twenty Two is around 12 hours east of the Leeward Islands moving west-nor'west at a brisk, cyclone-inhibiting 20 knots. This will bring some heavy showers and the odd fresh gust as it crosses the Leeward and Windward Islands tonight, but tropical development is most unlikely. I have a slight concern that this track is a little north of west – a nudge towards the Gulf of Mexico if this was to continue - since all other systems so far have gone due west, but none of the professional weather guys seem to think this is of any significance.

Disturbance Twenty Four launched from the African coast overnight and is currently midway between Dakar and the Cape Verde Islands, westbound at 12 knots. This has run into a monsoon trough which will take development momentum from the convection cycle, which may mean yet another crock rolling off the production line.
Another huge bloom of sand laden air looks set to leave the Sahara and enter the wind cycle in the next day or so which may mean little opportunity for storm development for the coming week. Even the Canadian guy is silent. We have had a number of new addressees over the past week or two, and more are always welcome - so we'll add a brief footnote. We start collecting information early each morning London time, or depending on which time zone I'm in. Then, once the overnight reports are in from the US (early to mid-afternoon our time), we issue our daily report as an email. Later these reports are posted on our website at www.watkins-marine.com and for those of you who understand the darker arts of social media, a daily Tweet on @watkinsmarine along with other matters of general maritime interest. Do join us.

Stand easy.
