Doesn’t look too bad, but then again, this is a mere hours-old system. I expect the beginning of an eyewall to appear in 12-24 hours.

I am only a meteorology enthusiast who knows a decent amount about tropical cyclones. Look to the professional mets, the NHC, or your local weather office for the best information.

Re: EPAC: FIVE-E - Tropical Depression
I'm going to place my bet between aspen's and cycloneye's, and guess 125kts peak. This has the looks of one of those EPAC storms that will get to Cat 4, and conditions look good for it. Good chance this starts a period of rapid intensification within the next 36-48 hours I'd say.

Re: EPAC: FIVE-E - Tropical Depression
00Z ICON takes it up to almost C3 by tau 84. 18Z HWRF is 93 kt at the same point (although interpolated HWFI is a little lower). Couple with the SHIP/LGEM output above, and I'd probably bring 05E up to 95 kt by the 72-84 tau point. I think it has a legitimate shot at major intensity.

That's actually the 18z ICON run...the 0z starts running in a few minutes. But I agree that this system has a decent chance of becoming a major hurricane in a few days.

Re: EPAC: CRISTINA - Tropical Storm
Tropical Storm Cristina Discussion Number 2
NWS National Hurricane Center Miami FL EP052020
1000 PM CDT Mon Jul 06 2020
Satellite imagery indicates that convection has increased and
become better organized since the previous advisory, although
convection has waned somewhat during the past couple of hours due
to entrainment of dry mid-level air. A 2213Z SSMI overpass showed a
small but well-defined mid-level eye feature in the 85 GHz data and
the latest TAFB satellite classification was T2.0/30 kt. Based on
the improved banding features and the mid-level eye, the intensity
has been increased to a conservative 35 kt.
The initial motion estimate is 300/13 kt, based on a blend of TAFB
and microwave satellite fixes. Cristina is expected to be steered
west-northwestward throughout the forecast period along the southern
periphery of a large deep-layer ridge that extends westward from the
south-central and southwestern United States. The latest NHC model
guidance has become more tightly packed around the previous forecast
track, so only minor tweaks were made in the form of a slightly
faster forward speed. The NHC track forecast lies close to the
simple consensus models, which are a little south of the
corrected-consensus model HCCA.
Cristina is expected to remain in quite favorable environmental and
oceanic conditions for the next 72 h or so. The small inner-core
eye-like feature and the expected low vertical shear and impressive
upper-level outflow conditions suggest that rapid intensification
(RI) could occur at some point occur during that time. However,
recent entrainment of dry mid-level air into the eastern
semicircle has eroded convection in that part of the circulation,
and the dry air may have even penetrated into and disrupted the
inner core itself. Given the aforementioned uncertainty in the
structure of the cyclone, RI is not being explicitly forecast at
this time, although the official intensity forecast is higher than
the previous advisory through 96 h. By 120 h, significant weakening
should be well underway when Cristina will be moving over 24-deg-C
sea-surface temperatures. The NHC official intensity forecast
follows the trend of the previous forecast, and there is a distinct
possibility that Cristina could undergo RI and also become a major
hurricane if the inner-core region has not been disrupted.

Re: EPAC: CRISTINA - Tropical Storm
I don’t think Cristina will have much trouble mixing out that mid-level dry air. RI will probably be delayed, but given how favorable the rest of it’s environment is for the next few days, it has plenty of time to get itself ready to explode.

South Texas Storms wrote:1900hurricane wrote:00Z ICON takes it up to almost C3 by tau 84. 18Z HWRF is 93 kt at the same point (although interpolated HWFI is a little lower). Couple with the SHIP/LGEM output above, and I'd probably bring 05E up to 95 kt by the 72-84 tau point. I think it has a legitimate shot at major intensity.
That's actually the 18z ICON run...the 0z starts running in a few minutes. But I agree that this system has a decent chance of becoming a major hurricane in a few days.
I actually meant the intensity consensus ICON NHC has in the a-decks, not the global model ICON, although I can understand the confusion.

Re: EPAC: CRISTINA - Tropical Storm
I love how everyones so surprised that the EPAC may pull off a major hurricane. In any normal year, we (or at least I) would take a major hurricane for granted. Just really goes to show how low our expectations have been for this basin this year. It looks like Cristina will finally put on the show that we have been looking for out of this basin and will not be another failed modeled hurricane that never comes to fruition (looking at you, Boris).

Re: EPAC: CRISTINA - Tropical Storm
Looks to be becoming more CDO dominant. Expected but given how banding dominant it was, its former structure was not sustainable for serious deepening.

Re: EPAC: CRISTINA - Tropical Storm
Yes, this is the type of system we were waiting from the EPAC, a fast forming Cyclone that has a chance to be a classic cat 4 major hurricane. Hello Cristina! I think EPAC is tired of being ignored this year

Re: EPAC: CRISTINA - Tropical Storm
Tropical Storm Cristina Discussion Number 3
NWS National Hurricane Center Miami FL EP052020
400 AM CDT Tue Jul 07 2020
Deep convection is gradually expanding over the center of Cristina
and in curved bands over the western portion of the circulation.
An ASCAT-B overpass from around 0430 UTC showed maximum winds of
around 35 kt. Based on that data and Dvorak estimates of T2.5/35
kt from TAFB, SAB, and automated values from CIMSS at the
University of Wisconsin, the initial wind speed is held at 35 kt.
Cristina is expected to strengthen during the next few days due to
the favorable environmental conditions of low wind shear and warm
SSTs, and its developing compact inner core as observed in
satellite data. The only limiting factor is some dry air that has
entrained into the eastern portion of the circulation. However,
given the largely conducive conditions for strengthening, the NHC
intensity forecast lies at the high end of the model guidance
during the next 3 days. Although it is not explicitly forecast,
rapid intensification could occur sometime during the next couple
of days. Cristina will likely be moving over SSTs below 26 C and
into a drier and more stable air mass late this week and this
weekend, and that should induce a weakening trend. This intensity
forecast is mostly an update of the previous one and in best
agreement with corrected consensus model HCCA.
Satellite fixes indicate that Cristina is moving west-northwestward
at about 11 kt. The track forecast reasoning is fairly
straightforward. A mid-level ridge centered over the southwestern
U.S. is expected to strengthen in place during the next several
days. This should keep Cristina on a west-northwestward path well
offshore of Mexico through the remainder of the week and into this
weekend. Only minor changes were made to the previous NHC track
forecast, and this prediction lies near the middle of the guidance
envelope.
FORECAST POSITIONS AND MAX WINDS
INIT 07/0900Z 11.5N 102.4W 35 KT 40 MPH

Re: EPAC: CRISTINA - Tropical Storm
Convection has really diminished overnight. Looks like it’ll take significantly longer to begin any phase of RI.
