EPAC: LINDA - Post-Tropical
Moderator: S2k Moderators
She looks really good and this area of the EPAC is notorious for the monsters when it gets hot. I'd say ceiling could be high with this one, another cat 4+ in the works?

Absolutely, especially with the intense CDO it has. Not a whole unlike Dolores and Marie.

If that eyewall completes without a hitch, I'd put my money of Rapid Intensification.

Looking at Dvorak paperwork, this is a T4.0 IMO. This is likely very near or at hurricane status. While we've had some bad luck with microwave, I am sure the storm has build an inner core and like some sort of microwave eye though I don't think it is closed yet and since the CDO is thick, will take some time to clear, but at least with this storm we won't have to worry about not having a thick enough CDO to receive high T numbers from SAB and TAFB.

Re: EPAC: LINDA - Tropical Storm

Not bad but thought it'd be a bit better than this. Still ahead of schedule.

Re: EPAC: LINDA - Hurricane
HURRICANE LINDA DISCUSSION NUMBER 5
NWS NATIONAL HURRICANE CENTER MIAMI FL EP152015
900 PM MDT SUN SEP 06 2015
Linda has been rapidly intensifying. Within the cyclone's sprawling
circulation, a relatively small central dense overcast (CDO) has
formed during the last 6 to 12 hours over the estimated low-level
center. The deep convection within this feature has expanded in
coverage, the associated cloud tops have cooled considerably, and
its shape has become increasingly more symmetric. A 0110 UTC
Windsat pass confirmed the rapid increase of inner-core structural
organization, with a closed low-level ring of convection evident. A
TAFB satellite classification of a T4.0/65 kt and the latest
UW-CIMSS ADT value of 4.2/70 kt are used to raise the initial
intensity to 65 kt.
The current rapid intensification is likely to continue for another
24 hours or so, since Linda will be moving over anomalously warm
waters of 28 to 29.5 deg C and embedded in a very moist environment.
The only negative factor could be some northeasterly shear as
indicated in SHIPS model output. However, this shear has not
prevented Linda from strengthening much faster than the
climatological rate of one T-number per day thus far. A more
poleward and faster track forecast (described below) should bring
Linda over cooler waters sooner, and increasingly unfavorable
thermodynamic factors should cause rapid weakening to begin in 2 to
3 days. Remnant low status is shown at day 5, but it would not be
surprising if it occurred earlier. The new intensity forecast is
higher than the previous one and shows a peak intensity in 24 hours.
Overall, it is just above the strongest guidance, the SHIPS and FSU
Superensemble output, in the short term and near the multi-model
consensus after that.
Linda has been moving more poleward and faster, and the initial
motion estimate is 320/12. Water vapor and upper-air analyses show
a large mid-level anticyclone near the Texas-Mexico border, with a
weakness in the ridge between 120-130W. Global models show Linda
moving northwestward to north-northwestward toward the break in this
ridge within a deep-layer southeasterly flow during the next couple
of days. As the ridge weakens and shifts westward over northern
Mexico in 2 to 3 days, Linda should continue northwestward but
decelerate. The rapid weakening forecast to begin around that time
should make Linda a progressively shallower cyclone, and its track
is forecast to bend west-northwestward and westward by days 4 and 5
as it will then be under the influence of the low-level subtropical
ridge. The new track forecast is shifted to the right and faster
than the previous one through 72 hours, and is close to the
multi-model consensus. By day 5, the track is slower and a bit to
the left of the old forecast.

I think if it can EI and develop the eye quickly it has a shot. But it would just as quickly ramp down, we've seen moving slow cause issues quite a few times this year here.
