[Jyo_hurricane] TS Karen, the remains of Lorenzo, and TD 14: September 28, Update A

I'll start with the easiest first.

TD 14:
This is a new Tropical Depression, way out in the eastern Atlantic,
close to the Cape Verde Islands. It has some circulation and
convection. It is heading in a northwestward direction into the
Atlantic at the moment. Unless someone tells me they know someone on the
Cape Verde Islands, I won't send anything else on this until I becomes a
named storm. So... er... more on this later today then.

TD Lorenzo, formally known as TS Lorenzo, and briefly known as Hurricane
Lorenzo:
He was moving so slowly that he did have a chance to intensify some more
before making landfall. He was upgraded to a hurricane yesterday
evening, and stayed as such for about 5-6 hours, but rapidly lost steam
(puns always intended :) ) after making landfall at around 1 am this
morning in Mexico. He's now inland and a depression so this is my last
entry on him.

TS Karen:
She's still out in the Atlantic and that very strong westerly wind shear
is successfully keeping her disorganized, so all the convection is to
the east of the circulation. Until a few hours ago there wasn't too much
deep convection to speak of, but since the last NHC advisory the deep
convection has picked up again. This might be a mid-afternoon
strengthening. The NHC forecast has her downgraded to a depression at
the next advisory, but with this convective activity, they might hold
back from that. Either way, she's a weak system at the moment.

They did move her long-term track a little closer to the islands, as
expected. Her movement has been a little doolalee (sp?) today, because
the high pressure that has been steering her in a west-northwestward
direction until now has changed a bit. It stayed strong to the north and
east, but also started building up to the west, so she has had this
little pocket in which she is moving around in a circular manner - she
started at 15.1N, 49.2W a few hours ago, and is now at 15.9N, 49.2W but
looks like she might head back southward a bit - it is difficult to tell
when she will finish this circular sort of motion. There's a chance she
will get out of this and instead of resuming her west-northwestward
track, she will move a bit more north-northwestward (away from land) -
it is tricky to see at the moment, so I might send out another note
later today once she has finished dancing in circles.

That's all for now folks!
