Swells From Leslie Will Reach The Coast This Week


bluewave

Recommended Posts

The modes are pretty keen on developing the next tropical wave into Leslie. While most models keep Leslie

well offshore, the Euro is hinting a a set up that may bring some large swells to the coast for the surf

competition in Long Beach early in September. The Euro develops a block to the north while it has

a closed low off the Southeast Coast. This type of pattern could draw Leslie close enough off the

coast to send in a large swell.

Love wave watching party's, to bad it can't come more west.

Today's (30/00Z) run of the ECMWF model shows a very improbable hurricane threat to Cape Cod in about 10 days. It shows the upper trough now over the Northeast pinching off into the Bermuda Triangle and merging with the remnants of Tropical Storm Isaac, which along with a strong Western Atlantic ridge would hurl soon-to-be Leslie NNW from near Bermuda to Cape Cod. Very improbable, but then again I just watched a teammate of my son's hit a very improbable walkoff grand slam to win a summer league baseball championship. :)

Regardless of ultimate track it will for sure send a large swell to the east coast. Based on the expected large size and track west of or close to 60 west we are in for a large multi day swell. Large size means large fetch and hence large sea state. A good analog is igor 2010 which took a similar track and produced a large swell for the entire east coast.

I think we want to see as much space between Kirk and Leslie as possible, the quicker Kirk can get out of the way, the quicker the ridge can build back overhead. Then the trough moving through SE Canada needs to be watched closely. The 06z GFS is much slower and deeper with the trough than the 00z ECMWF. On the 06z GFS, the trough digs almost all the way to Florida and swings negative, drawing Leslie towards the coast, with the closest approach to this area around hrs 228-240. The 00z Euro is not nearly as deep, but the timining is similar. The 00z Canadien is commical, with Leslie making it to the Latitude of about Norfolfk, VA before getting captured under the ridge, and then pushed westward (East of Bermuda). At the same time, a deep trough is along the East Coast and we have a soaking rain storm. It's notable because the strength and depth of the trough is similar to the 06z GFS. The NOGAPS is similar to the Canadien with regards to the location of Leslie, strength, and position of the ridge overtop, but much weaker and shallower and less amplified with the trough along the east coast. Of course this is nothing more than speculation 10+ days out, but the big players to watch appear to be how fast Kirk gets out of the way, how far West Leslie can make it before that trough approaches the east coast, and the strength and depth of that trough. I would be interested to see a list of analogs for this one.

New England Hurricane of 1938 is one of the best analogs for this, with the cutoff low over the great lakes.

please stop with the :weenie: posts, that setup is not even close.

Agreed 38's setup was like winning powerball.

I think NHC is way low on their intensity forecast. This is by far the best shot we have had this year for a major. Peak of the season moving into the meat of the MDR where countless storms have gone major in the past a weak shear environment and they are worried about anticyclone placement? I don't buy it.

I am Glass 5/64th optimistic on better than just surf, but an actual sensible weather impact in Brooklyn, and Glass 13/32nd optimistic on dangerous rip currents on Tri-State beaches with direct ocean exposure.

We used to go to a place called Tobay beach when I was a kid and surf was rough,

Since this looks like the banter thread I'll post here.....leaving at 4PM for a cruise to Bermuda. Gets into Bermuda Wednesday morning and is supposed to depart Friday afternoon. Really hope the cruise goes forward and we get some 10-20' waves on the ship. The cruise must go on!

I think we can write Leslie off for the east coast. The models last night show a deep trough coming into the east. As we head deeper into September, the troughs will come in more frequently.

Definitely not...it's hard to keep up with all the track changes. Leslie is already approaching 65W.

:twister:
