Here is Wilma undergoing an EWRC. Look for an outer eyewall to form and a moat (empty space) to develope between the the two eyewalls.

Probably the most important thing to know is that they take a good amount of time...absolute minimum 12 hours, and usually more like 18-24 hours.

People proclaim FAR too many of them and often claim they're occuring a couple hours apart..."EWRC" has become one of those catchphrases people toss around without really completely understanding them.

Also another problem is ALL weakening of any hurricane is attributed to EWRCs.....which obviously is not the case; what seems to drive it is people disappointed in a storm that's weakening due to shear, dry air, etc. and proclaiming a mythical EWRC allows them to kid themselves it's going to quickly restrengthen.

That is a FANtastic loop. Tiny eye, new eyewall forming, eye filling then clearing out.
Great link!
