@WxTca "There's been a lot of discussion regarding the nature of #Melissa's EWRC and I can confidently say that I am not qualified to make an assessment here. TDR reveals a noticeable asymmetry in vertical velocities indicating the storm is feeling the shear w/ updrafts downshear"

"A microwave overpass of Hurricane #Melissa reveals its violent eyewall as well as a large primary band connected to this feature. Otherwise most banding is to the east of the storm have to wonder if the wind shear is helping to hold off any eyewall replacement cycles for now"

"The air force reconnaissance mission sampling #Melissa has found that its central pressure has fallen to the low or mid -890s pending a dropsonde. Seeing one of the most incredible tropical cyclones I have ever tracked heading straight for land is incredibly sobering"

"#Melissa is rapidly intensifying to the southeast of Jamaica with days to go before landfall. Intense convection is wrapping upshear in the eyewall and outflow has improved in all directions. An aircraft has found that pressure has fallen to about 971mb pending a dropsonde"

"With how quickly #Melissa is intensifying I would watch out for any deviations to the southwest in its track over the coming days as storm with more vertical depth (i.e. stronger) will feel the mid-level northerly flow more. This could perhaps afford it more time over water"

"Some observations using TDR in #Melissa this evening: X. Unsurprisingly given how rapidly it is deepening the system is vertically aligned. Moreover the storm is also vertically deep which increases the odds of deviations southwest in the coming hours due to midlevel ridging"

"@webberweather As a reference here's a composite of 0.5-3km SRH in sheared but intensifying TCs rotated into shear-relative quadrants. Lots of +SRH in the let of shear quadrants"

"It's subtle but you can see a powerful mesovortex deform the boundary between #Melissa's eye and CDO here. As it moves through very cold convection has begun to erupt starting from the downshear side of the storm. Have to wonder if this'll cause further intensification"

"I think #Melissa is finally beginning an eyewall replacement cycle. Data from the TDR showed that a ring of vorticity is coming into existence outside the eyewall while reflectivities are increasing here on Jamaican radar. Bursting convection is also increasing in the outer CDO"

"Ultimately this feature in #Melissa ended up evolving in a peculiar matter based on land-based radar from Jamaica where the inner eyewall appears to have essentially 'merged' with the outer. The product is a slightly larger and apparently more intense eye than we had before"

"@AndyHazelton I think there's a strong argument here. Per TDR the strongest winds at 0.5km were in the northeast quadrant. The dropsonde outright supported 160kt and seemed to have rotated from the north into the western quads. Neither USAF nor NOAA sampled the NE quad"

"2. The strongest updrafts in #Melissa are in the upshear quadrants. These updrafts are effectively stretching vorticity and strengthening the vortex. +SRH in association with these also will likely help the eyewall contract over the coming hours as the storm intensifies"

"The two VDMs we've gotten from the NOAA aircraft confirm that these vortical hot towers have led to eyewall contraction with the diameter falling from 25nmi to 17nmi. Additionally the storm appears to be moving southwest at the moment"

"#Melissa continues to deepen but has not strengthened as quickly as the satellite appearance indicates. Jamaican radar indicates that concentric eyewalls may be beginning in association with the storm. This secondary eyewall appears to be very close to the shrinking inner eye"

"Since the time of this tweet the developing secondary eyewall has grown more prominent on radar from Jamaica. Of note are the outwards propagating vortex rossby waves emanating from the inner eyewall constructively interfering with this feature"

"Contrast this with every single other faux EWRC that has faked us out over the last X days -- these look more like intense bouts of vortex rossby wave activity and slow contraction. The only real outer eyewall at any point in this video was aborted at some point for some reason"

"@AndyHazelton Sorry I misread my own plot -- those are 3km winds here"
