East Pacific Hurricane Season 2013


Recommended Posts

Eh so much for the no majors futility streak. Raymond will need to get sheared fast for that to hold.

What do you know the storm Josh opts of will turn out to be the hawtest storm in many years.

OK, you just hush up! :D

The GFS and ECMWF initialized terribly with the system. The NHC noted significant uncertainty in their forecast and stated it would not take much for this to come ashore.

Go on.

You guys are terrible, getting me all worked up like this. :D

But, yeah, that MW is crazy-hawt.

Its certainly not moving fast tonight, just merely drifting north. The other factor I have been neglecting that is just as important as intensity is the size of the system, which is below average. Because of this, the PV tower is also smaller than a normal TC, which would limit the impact the upper-level steering currents to the north. I don't blame Josh for having cold feet, especially when the guidance continues to shy away from a direct landfall.

Thanks.  Yeah, it's mega-hawt-- my kinda cyclone all the way-- but the setup just ain't clear enough.  Even if it comes ashore as an intense landfall-- which it very well could-- I still feel my decision makes sense, given the indicators.

With that said, the ECWMF's track over the next 24-36 hours is absolutely bazare... it still hasn't caught on to the whole RI thing thats been ongoing the last 24 hours, but it intensifies the system as it pushes it to the SE. I don't think I've ever seen a strong intensifying TC moving southeast in the EPAC since TC Norbert in 1984.

If you want a good laugh you have to see the loop (below)

Eye is clearing out nicely.  BAMD continues to suggest that a deep system (as Raymond is rapidly becoming) would make landfall in about 24 h.  That said, last few frames suggest that northward motion has slowed significantly.  Could just be wobbles as the core continues to become better defined, or it could suggest that the southerly deep layer steering flow is not as robust as modeled.  Need a few more IR images to say for sure. 

 

Looks like the early signs were quite telling...

 

Deep layer steering was weak to begin with.  A subtle but influential change in the evolution of the synoptic environment now favors a more easterly component to storm motion as evidenced by the abrupt westward shift of the BAMD at 12Z.  Coastal MX will be hit by rain and wind, but the core will stay offshore.  Good call on the no-go Josh.

See, we've gone a year and 5 days without a major in the EPAC, and now that we have one, I'm like really really excited.

 

:D   :)

Hey, thanks, man.   :)

Its so obvious that southwesterly shear is not the culprit to blame for Raymond's weakening today. Instead, its due to upwelling of cooler waters underneath (+ potentially some dry downslopeing off Mexico). OHC is not all that high underneath the storm currently, and satellite observations of SSTs won't be able to update fully the region until Raymond and its associated convection and cloudiness moves out of the way. Its likely the system has burned through all its fuel as noted by the warmer cloud top temperatures near the center vs. in the outer bands away from the center.

 

Once Raymond starts moving to the west it should be able to recover, but the radial re-distribution of PV based upon the displacement of deeper convection away from the center suggests the radius of maximum winds should grow in size.

Looks like something brief and weak could come of 98E.  Otherwise, looks like the season is coming to a close. 

 

It was an odd season, with 20 named storms, 9 hurricanes, but only 1 major - completely at odds with the previous 2 seasons that featured a very high NS:MH ratio.  Reminds me of the last 3 seasons in the Atlantic.

It's like the tropical cyclone version of Dutch Disease.
