Hurricane Barry was only active in the Gulf of Mexico - is that part of the Atlantic?

Andrea formed in the Atlantic Ocean, but only made it to Tropical Storm status

It was still part of the Atlantic hurricane season.

I heard a couple of weeks ago that there is an unusually amount of Sahara sand being blown across the central north Atalntic this year, which maybe is helping to stem the development of tropical systems.

Wrong! Barry formed in the Gulf of Mexico and at any rate it never reached Hurricane status: - It remained a Tropical storm with Hurricane gusts perhaps! So we have yet to see our first Hurricane in the Atlantic this 2019 season! :)

Yes Hot weather few weeks back from Sahara! I heard!

Same for the heat wave 2 weeks ago and the previous one back during End of June and even our first burst of unseasonably warm weather in February when we hit 21c in some parts of the UK.

I only count Hurricanes that are in the Atlantic. Usually by now we would have seen at least 2 or 3. We are struggling to see a TS in the Atlantic yet!? - A bit boring really! - Very benign this season thus far!

I’m hoping it’s going to stay boring and benign for at least the next month Tally. 

With regard to Saharan dust, that’s been the cause of some really beautiful pink skies at sunrise this summer!

As people have correctly pointed out Barry is technically an Atlantic system (officially) and also reached Cat 1 status by landfall. I was in the US at the time and coverage was extensive. 

The funny thing is the link you posted actually states, “Barry made landfall this afternoon in Louisiana as a Category 1 hurricane”.

In the same way I only count deep lows affecting the UK as official if the centre passes up The Solent 😉

Apart from the fact the GOM is included in the categorisation of tropical systems in the ‘Atlantic’ sector, many Atlantic born systems end up in the GOM anyway so your preference not to include them is a little odd.

Looks like things may liven up in the Tropical Atlantic sometime soon according to Accurate weather,:

Most of other reports described it as a TS though upon landfall. So even if it was a cat 1 it prob didn't last that long - maybe an hour for wind speeds of 75mph or more then decreasing?!

That doesn’t matter as it was still  a Cat 1 hurricane, albeit briefly.

Late start, but end of El Nino implies incidence of hurricanes will be back to average or even above by the end of the season

Still watching - analysis of current lack of activity here. Nothing expected for the next ten days.

Just seen a BBC weather article on Hurricanes, Typhoons and Cyclones.

https://www.bbc.co.uk/weather/features/48517418

I notice the area of coverage for all 3, but especially tropical cyclones, covers the equator.

Considering the direction of rotation of these intense tropical lows in both hemispheres, which way do they rotate if they are over the equator?

Logic suggests it's not possible as the part of the low to the N of the equator would rotate in an anticlockwise direction, the opposite being true for the southern portion of the low. Convergence? 

Sarah K-L does mention that they never cross the equator; but look at the coverage zones.

Thanks David; then I can conclude the coverage area in the maps shared by SK-L were just generic, in respect of the different names for TSs and not to be taken literally (if that's the right word). 

A good link you gave. The storm tracks in the map completely missing the equator very clear.

Well, that’s good news for our flight out.  I’d like it to stay quiet until 4th September.

Tropical storm Chantal has popped up in mid-atlantic (is it an unexpected development of the disorganised area of thunderstorms which has been creeping up the US coast?) but forecast is a) no more than a storm b) track just spirslling around, nt heading this way

Another extraordinarily quiet hurricane season seems on the cards again this season. Recently arrived back from the Yucatan Peninsula in Mexico and the Sargassum issue there has been pretty bad for the last few months with what I believe to be down to declining hurricane activity over the last several years..... Of course this is just a pet theory alongside Amazonian pollution runoff into the Caribbean Sea.
