Tropical Storm Helene, September 2018

[CARIIS]

Wanted to get this started -- it is better for all of us to have eyes on her.

We can stay ahead of it if the thread is up and going

She is at 70% chance right now.

Yuk

Helene and Issac!

I’m hoping and praying for everyone who could be affected. Are the forecasters saying it is going to be a severe hurricane season?

 

[imstilla.grandma]

I’m worried for all of y’all. My husband is trying to keep an eye on the weather patterns but Mother Nature can be an unpredictable beast. Take care everyone. Prepare for the worst and hope for the best, my fellow Websleuthers.

ugh

in a week were prob gonna have 3-4 of em crusing across the atlantic

the africa ones generally to hit east coast

the ones that start in caribbean tend to gulf coast

what i have never understood ( they need hot water ) when there are several going across similar water why one storm ahead does not cool the water that would weaken the ones following

and then if there are three two ahead of the third it seems like there would be a bigger swath of cooler water from the two ahead of it

Passing of Hurricanes Cools Entire Gulf

It is well known that a warm ocean favors the development of hurricanes. Less well known is the fact that the passage of a hurricane over the ocean can cause the upper ocean to cool substantially, which can influence subsequent hurricane development.

Windy.com has Helene crossing the Leeward Islands (Antigua, Barbuda, St Martin) on Friday 14th, then tracking south of Puerto Rico and Hispaniola. Probably heading towards Jamaica.

14th - Windy as forecasted

*sigh*

My goodness so many already. Sounds like a bad year coming for them.

 

[Bravo]

We just booked usual Condo in Freeport Bahamas. Hopefully weather doesn't hit there. Hurricane Matthew hammered the property so we didn't go that year. I feel like I am being selfish tho.

All change down by Cape Verde ....

The disturbance we all thought was going to be named Helen is now Tropical Depression Nine. The storm behind that, which we thought would become Isaac, has strengthened to storm force and is now Helene.

National Hurricane Center

I've tracked the newly named Helene on Ventusky as a far as the projection goes and it shows her tracking northwards into the middle of the Atlantic, mid way between Spain and the US, by 17th September. Unfortunately this means there's a good chance she will be dragged towards Ireland and the UK in the days following.

Windy.com shows the new Helene tracking closer to Europe than Ventusky does. I think this makes it more likely that Europe, especially Ireland and the UK, will get a battering.

UPDATE: this weather system has not developed so is currently Tropical Depression Nine, NOT Tropical Storm Helene.

 

[CARIIS]

oh goody

bye bye helene

 

[JerseyGirl]

After moving on a westerly path over or very near to the Cabo Verde Islands this weekend, Helene is expected to move more toward the northwest over the open waters of the central Atlantic through next week, posing no direct threat to land.

Where are Helene and Isaac headed in the Atlantic?

 

[CARIIS]

This may help folks :

advisories for Atlantic tropical cyclones are normally issued every six hours at 5:00 AM EDT, 11:00 AM EDT,5:00 PM EDT, and 11:00 PM EDT (or 4:00 AM EST,10:00 AM EST, 4:00 PM EST, and 10:00 PM EST).

or to put it another way ! basically nothing is going to change for hours in terms of changes

As landfall gets closer they might increase number of flights into the beasts

Oh bugger, this is getting confusing. Tropical Depression Nine, that we originally thought was going to become Tropical Storm Helene, has in fact developed into Tropical Storm Isaac.

Helene has become a hurricane southwest of the Cabo Verde Islands

HURRICANE HELENE

 

[JerseyGirl]

Latest charts on #Helene show its path still heading for Ireland with strong gusts Monday night as she moves through Ireland. Still a long way off and the track will chop and change but something to keep a close eye on.
