Re: ATL: LEE - Hurricane - Discussion: Forecast to be Cat 5
Very warm eye. Remember, in this basin it is common that eye temperature is more indicative of strength than CDO temperature.

I believe that's the upper-level mission. The lower-level one takes off around 5 PM Eastern and will arrive at Lee's center about 2.5 hours after

Well, that is going to be plugged into the models with the dropsondes.

Probably the 0z runs and a few on the 18z runs

Guess I misunderstood a bit, sorry. The TCPOD did say that an upper-level mission would leave around this time; I think I just misinterpreted your reaction somewhat. Looking forward to the results of both missions.

Even on 1-min floaters, the rate of intensification is incredible.

We now have Major Hurricane Lee. It is official.

If they go 105 kt that would be a very impressive 35 kt intensification in 12 hours. Note that the RI requirement is only 30 kt in 24 hours so this is far beyond that.

Re: ATL: LEE - Hurricane - Discussion Update: 18z Best Track up to Cat 3, 105 kt
Centre region temp is 18.4C and is already approaching the highest value Jova ever had (20.3C). Raw T# also already up to 6.6 now. We're really seeing the most impressive RI of both the EPAC and the NATL in years on the same day
. What are the chances.

I think even 105kts is an underestimate. We'll know for sure in about 4 hours?

Lee met the RI requirement yesterday, apparently met it today, and is forecast to meet it again over the next 24 hours. Maybe someone can run a query to see when a storm rapidly intensified in three consecutive 24 hour periods.kevin wrote:WalterWhite wrote:We now have Major Hurricane Lee.

Cdo starting to uniformly cool now. W band all the way around the center with wmg in the eye on Dvorak. Jova’s transformation yesterday was amazing, but Lee’s is keeping right up there with it.

This is absolutely incredible. Looks like a Cat 4 already. Does take time for the winds to catch up but it is definitely rapidly intensifying

Re: ATL: LEE - Hurricane - Discussion Update: 18z Best Track up to Cat 3, 105 kt
Well not much to add here, but to say... Wow what a marked change in structure in only the last 12-15 hours! Honestly I expected only gradual organization today, with the real RI occurring tonight into tomorrow. This shows the internal structure was likely further along than many of us thought yesterday/last night despite the ragged IR structure. This view is at least partially supported by the fact that the microwave passes yesterday showed a pretty good and established core structure (better than what you would expect looking at IR and vis). Will be interesting to see the intensity trajectory over the next 5 days... environment obviously not a problem with low shear, high OHC, and a most low-mid lvls, so any intensity ups and downs will likely be driven primarily by EWRCs.
Let's all also be thankful this didn't end up being a NE Carib direct threat (obviously swells, surf, rips, etc notwithstanding).

Perhaps upgrade the name to Hurricane Lee Majors at the next update.
