LakeEffectKing Posted September 7, 2017 Share Posted September 7, 2017 For the love of God....there has not been and there is no indication of an ERC. As long as the outer eyewall attaches occasionally to the IEW (transporting angular momentum inward), you will not see the IEW contract. Concentric eyewalls can be very stable, as long as they remain far enough apart, as to not rob the IEW of surface "energy"....as a matter of fact, if the IEW remains very stout...an outer eyewall will struggle to "take over"...that's where we are at now... I'm drafting up my thoughts/track map....I'll post in a bit. Link to comment Share on other sites More sharing options...

NJwx85 Posted September 7, 2017 Author Share Posted September 7, 2017 The ERC may have been disrupted due to some land interaction thanks to the close pass to PR. With that being said, it still has 3 more days over very warm water with nearly optimal atmospheric conditions to work with. All guidance shows Irma strengthening in the Southern Bahamas, so current intensity is irrelevant now that we temporarily don't have any threats to land.

Expand Similar to the often erratic, stubborn, and mind-boggling behavior toward what "appears" to be the end of the life-cycle of violent tornadoes... Just not a lot known about how ERCs work exactly, especially in intense hurricanes that tend to act quite stubborn to outside influences and have rather solid/steady inner-core dynamics.

Sent from my SM-G930V using Tapatalk Expand As just noted by another poster, an ERC is typically complete within a 24 hour period, and is usually followed by restrengthening if conditions allow. Thus, it's currently so far away, it's highly likely there will be a minimum of at least one more ERC prior to reaching the USA. Although ERC's can help moderate intensity somewhat, in the aforementioned short term, it also helps expand the hurricane force wind field. In cases such as Matthew and a potential track just offshore of the Fl Peninsula, an ERC can actually be the difference between a hit by the W eyewall and a near miss. Moreover, a larger hurricane could be more devastating than a somewhat smaller, yet slightly more intense one; relative to MSW. Link to comment Share on other sites More sharing options...
