ATL: Ex Tropical Storm EARL - Discussion

[KWT]

Yeah Crazy, interestingly though thats coming in from the E.side and 130kts isn't perhaps quite as high as I was expecting, though the NE Quadrant may well contain winds higher then that.

[dizzyfish]

I believe they detoured the research mission from Fiona to Earl. Correct?

probably 140-145 knot flight level in ne quad. hopefully they check it out.

That is correct.

My avatar is Hurricane Daniel 06, an annular hurricane as well.

What do you think will happen when this hits the Gulf Stream.

[KWT]

Looks like the motion has been to the NNW as well, hopefully we see a couple of decent easterly wobbles to really reduce the threat to the east coast in the next 12hrs...

Going to be a long day for some tomorrow....

[Dean4Storms]

What do you think will happen when this hits the Gulf Stream.

Don't know that the Gulf Stream will make a whole lot of difference once it reaches it off the NC coast as SW shear from the advancing trough could counter any advantage that the increased SST's produce.

SUMMARY OF 800 PM EDT...0000 UTC...INFORMATION
----------------------------------------------
LOCATION...27.2N 73.5W
ABOUT 565 MI...910 KM SSE OF CAPE HATTERAS NORTH CAROLINA
MAXIMUM SUSTAINED WINDS...135 MPH...215 KM/HR
PRESENT MOVEMENT...NNW OR 330 DEGREES AT 18 MPH...30 KM/HR
MINIMUM CENTRAL PRESSURE...941 MB...27.79 INCHES

Looks like the turn to the NNW has started...that is great news...although it's too early to tell if it's a trend, Earl has definitely tracked east of the forecast over the last few hours.

[Hurricane Andrew]

8pm
Winds:135
Moving:NNW at 18 mph.

Per the NHC- http://www.nhc.noaa.gov/index.shtml

[KWT]

Yeah recon confirms the NNW motion, maybe more then 330 as well, looks like 340 to me based off recon obs at the moment.

[RL3AO]

What do you think will happen when this hits the Gulf Stream.

Gulf stream is soo overrated when it comes to tropical cyclones. Its important when you have stalled systems trying to develop off the East coast, but when you have a moving hurricane, it doesn't really matter. It doesn't matter if it spends a few hours over water a few degrees warmer. It does matter if its a stalled system that spends 3 or 4 days over the warmer water.

[CrazyC83]

Notice also the Recon extrapolated pressure is down to 927mb, it is probably a bit higher than that but still around 935mb. Flight-level winds easily support Cat 4.

What is for sure is its highly likely the pressure is lower then the 941mbs suggested by the NHC right now...
