isabel challenge 2
|
on september 6th, ed dunham gave us the isabel challenge.. the challenge was to use your amateur forecasting skill and place the center of the storm to within two degrees and intensity to within 10kt on 12z september 13th... on at the time a lowly tropical storm in the eastern atlantic. right now it looks like storm cooper will come closest, as his position isn't far removed from the nhc's forecast. if the intensity isn't signicantly lower by then, everybody busts, as no one guessed higher than 110kt.
but, here's another opportunity to place isabel a week out:
where will isabel be to within 2 degrees, and how strong will the storm be to within 10kt, at 00z on 18 september (thats 8pm eastern wed. september 17th)? post any time tomorrow.

Re: isabel challenge 2

i'll go first.
isabel 00z18september
29N 77W
120kt
i'm obviously reasoning isabel will make landfall, and think it will be a major hurricane. in this case i'm picking the odd zone between daytona and charleston for landfall, which is a rare area for a big storm to go. but i'll chance it.

Re: isabel challenge 2

I'm gonna go with a fish spinner and send the storm out to sea as it approached the Bahamas.
30N 74W 95K
My first instinct was that it wasn't even going to make it that far west and we'd be looking at 71W....

Re: isabel challenge 2

My answer for the challenge: 28.5 N, 78.5 W at 112 Kts (off the coast of the Georgia-Florida border). Prediction sidenote: I am up here in VA Beach, getting married on Sept 20....outside. So, of course, my prediction stalls Isabel for a day or 2 off the coast, then she heads north, aided by that slowly moving advancing front. Isabel makes landfall near the SC/NC Border on Sept 21 -Sunday and curls out to sea over eastern VA on Monday-Sept 22. Naturally, this assessment is based on my past experiences with emily, fran and other she storms not on my bad luck of planning a wedding during mid Sept.

Re: isabel challenge 2

This is tough....many, many possibilities.
I don't think Isabel will have made landfall at that point in time. I do think it'll be near the Gulf Stream, and I don't buy a substantial weakening trend between now and then.
My best guess? A WNW trend for the first few days, with a slow forward speed, followed by some jogs both NW and W. As for a position and intensity estimate?
28°N, 76°W, 120kt.
My best guess for beyond that places the greatest threat between Wilmington and Daytona Beach...my eventual track thinking is not far off from HF, in calling for a possible uncharacteristic landfall region.
But with this kind of forecast, I'm probably way off!

Re: isabel challenge 2

In reality, mine anyway...I still hold to a position @ 9/13 12z of 22.8 / 63.2 @ 95knots. I see I may come close on track but may blow the kt/mb. I would like to see a turn north and it still may happen but as of this am I see it as I posted this am at 23.7 / 71.6 9-18 00z. Maybe the factors will be very different then and let her spin fish

Here's what I think....

Max winds..... 110K
Direction WNW at 9K with a forecast to shift to a more NW direction... potential impact to SC and/or NC...

Well its time to sign in. Did this at work so I'll probably go down in flames with it because of the recent slowdown (but I'll have lots of good company). 18/12Z 28.5N 76.9W 115kts
Moving NNW at 14kts.
Guess it would help if I forecasted for the correct time:
18/00Z 27.5N 75.5W 115kts
Cheers,

Re: isabel challenge 2

Wow. There are a lot of similar predictions (relatively similar on a global/oceanic scale). It seems as though everyone has it south of the GA/FL border - a bit East of C-N FL, some further south. Everyone's got it at least as a Cat 2 - mine may be underdone @ 95knots.
As for the ultimate landfall, I've already put mine out in the last news article. I'm calling for landfall between Charleston and Wrightsville Beach next weekend (Sunday - no way to tell). As noted in that thread, Super Typhoon Maemi offers a shot at some real clues 6-10 days downstream in the US. It doesn't often happen this close, but you might recall both of the storms originally were bottom heavy, and both developed into classic, intense storms.
I guess we'll see.
Awesome indeed.

No Ed is Offshore Melbourne by a couple of degrees, probably heading to the Carolinas. All of these are too close for comfort though as we're at 28N/80.1W.. that's not my guess. I'll say 26.2N/74W, moving NW at 10 knts; 95knots.

Re: isabel challenge 2

ah, don't worry bill. ssts around 80F in georgia coastal waters.. so anything strong would probably be on the slide when it comes in...? unless bastardi's perpendicular coast-strike gradient tightening comes into play...
well, i used to live in hinesville.. savannah hasn't taken a good hard lick since the 1800s, with an odd 1 or 2 every 20-30 years in the 20th century. sorry to say you guys are long overdue.

Sorry Bill B... but it should encourage you to know that I have no meteorological training whatsoever, and my guess is based almost entirely on the similar-tracked hurricane of 1893...

Major error on my part I just noticed running new software and imputing...... I should have said 27.3 NOT 23.7. My mistake so you can discount me from the running if you wish. I just kept looking a 23.7 then at my map w/ my plot and I said to myself this does not add up
Anyway 27.3 / 71.6 @ 100kts. for the record.

Re: isabel challenge 2

storm cooper, for attempting to cheat i hereby banish you from the competition. do not pass go, do not collect $200.
nah, considering you nearly nailed the last one, and played it conservative.. i saw your post and wondered what the hell you were doing. anyhow, this is just for fun.. not like you can be 'disqualified' or anything. to be honest, you need not be anything more than lucky to win at this, if you know just a little about how hurricanes behave.. of course if you get things right all the time or go through and explain your forecast philosophy and it checks out.. well, then you might start turning heads. that's what this is all about, getting better at our hobby.

safe to say you've gotten closest.. you will be a little southwest of the 8pm position, but within 2 degrees. your forecast intensity is on the money unless something big happens today. nice job, domino.

Out of 22 who threw out prognostications, 5 were within range on latitude, and 7 were within range on longitude.
5 had the intensity pegged.
4 had two of three of the parameters.
But only Domino had all three.
Off by a degree and a half of latitude, 0.4 degrees of long and dead on on intensity.
Good job, Domino!

I have to give everyone on this site credit for this one... before I came here all I knew was that a hurricane was a bunch of wind. Everyone here has done a great job helping and I've learned quite a bit from you all over the past couple years. Now if I can just predict what the weather will be like in the Bahamas for my cruise next week...
