Forum:2007 Atlantic hurricane season

AoI: Vigorous wave off Africa
I know it's too early for Cape Verde, but I have the NHC to back me up. Check out this loop. See that large wave with a hint of rotation? The NHC did. NUMEROUS STRONG SHOWERS AND THUNDERSTORMS FROM 5N TO 9N BETWEEN 19W AND 22W APPEAR TO BE WITH A SQUALL LINE AWAY FROM THE AFRICA COAST. THIS SQUALL LINE IS SUPPOSED TO BE PRECEDING A TROPICAL WAVE THAT WAS PUT ON THE 03/1800 UTC SURFACE MAP ANALYSIS ALONG 12W. LET US WAIT A LITTLE BIT LONGER AND SEE WHAT HAPPENS WITH THIS FEATURE. (from TWD) could this mean they're expecting something? Just something to possibly watch. Cyclone1 (18:53 UTC -5/06/2007)
 * Definitely no Surface low though. Also, it appears to be disintegrating. I think this will be a big Cape Verde year though. This is a much better page for Cape Verde, for everyone's reference (Since no one but me seems to know). -Winter123 00:33, 6 June 2007 (UTC)
 * Yeah, the NHC isn't showing any interest anymore. Cyclone1 (02:42 UTC -6/06/2007)


 * Another one 0_o - -17:55, 9 June 2007 (UTC)


 * Holy crap! This one looks much better! It's mentioned int the TWD. Well defined low, but convection has diminished a little. If it can hold out till about 35W, I bet we'd see an INVEST. Cyclone1 (18:41 UTC -9/06/2007)

Not a wave anymore it's a tropical low. Cyclone1 (18:55 UTC -9/06/2007)


 * Pretty impressive. It would be more interesting in August. ---CWY2190talkcontribs 19:12, 9 June 2007 (UTC)


 * Actually, I think it's more interesting in early June, because we usually don't see lows like this until August, when they are pretty mainstream. Cyclone1 (20:27 UTC -9/06/2007)

It's in the TWO. A LARGE TROPICAL WAVE...LOCATED JUST OFFSHORE OF WEST AFRICA...IS MOVING WESTWARD AT 15 TO 20 MPH. ASSOCIATED THUNDERSTORM ACTIVITY IS MINIMAL... AND ENVIRONMENTAL CONDITIONS ARE NOT FAVORABLE FOR FURTHER DEVELOPMENT. That says it all. It's gonna have to wait for now. Cyclone1 (21:10 UTC -9/06/2007)


 * I'm more interested in the area north of Panama. ---CWY2190talkcontribs 23:00, 9 June 2007 (UTC)
 * The models don't do much with that area, so I wouldn't be concerned with that blob right now, but our wave is looking great now that it's an INVEST. Cyclone1 (01:16 UTC -10/06/2007)

93L.INVEST
It's an INVEST now! And may I say, it's looking very impressive! Cape Verde is raring to go, and this season is just getting started! Cyclone1 (01:16 UTC -10/06/2007)


 * Ok I have to say it. WTF IS GOING ON!!!  A cat 5 cyclone in the Arabian sea and now an invest off the coast of Africa on June 9. ---CWY2190talkcontribs 01:38, 10 June 2007 (UTC)
 * Not to mention a preseason storm. Cyclone1 (03:16 UTC -10/06/2007)
 * Wow, that's looking extremely impressive! I sense another strange year ahead. Bob rulz 03:22, 10 June 2007 (UTC)

A LARGE TROPICAL WAVE...LOCATED ABOUT 550 MILES SOUTH-SOUTHEAST OF CAPE VERDE ISLANDS...IS MOVING QUICKLY WESTWARD AT 20 TO 25 MPH. THUNDERSTORM ACTIVITY HAS INCREASED THIS EVENING... AND SOME DEVELOPMENT IS POSSIBLE IN THE NEXT DAY OR SO BEFORE THE SYSTEM ENCOUNTERS UNFAVORABLE UPPER-LEVEL WINDS AND COOLER WATER TEMPERATURES. So, maybe a depression tomorrow, maybe a storm. Either way, this storm seems to have an ill fate. But still, third storm by June 10? WTF?! Cyclone1 (03:27 UTC -10/06/2007)


 * It looks more tropical that Andrea or Barry ever did IMO. ---CWY2190talkcontribs 03:43, 10 June 2007 (UTC)


 * That's one thing I think we can all agree on. Wow, I can't get over how organized this thing is. Cyclone1 (03:48 UTC -10/06/2007)


 * I'm just glad this is not in the Caribbean in September. So impressive looking for not being a TD.---CWY2190talkcontribs 04:07, 10 June 2007 (UTC)


 * I'm surprised it's NOT a TD. There must be some discrepancy in the NHC whether this is possible or not, just like how they couldn't name that STS North of Bermuda last year, for some reason. Isn't the earliest Cape Verde storm July 4th? Also, note how ridiculously far south this is. 7.5N!! I say name it a TD at least so it's not forgotten in the pages of history.


 * Also, take a look at this. Things were very favorable over the Cat 5 and very favorable over Africa, but unfavorable conditions are moving towards this weak cyclone. If it's going to develop, it better do it fast. -Winter123 05:24, 10 June 2007 (UTC)


 * Maybe the fact that the WindSat sensor has been offline since Friday AM accounts for the reluctance to name it a TD? 4.152.3.51 20:19, 10 June 2007 (UTC)


 * Right now, this INVEST (if it even does develop, I hardly believe it's even this well organized) has a chance to be the earliest Cape Verde system, but earliest third storm? Not a good chance. It's got a better chance of usurping the second placer (the Escuminac Hurricane of 1959 formed on June 18th) than of dethroning the champion (1887, formed on the 12th of June). Jake52 My own private island 06:40, 10 June 2007 (UTC)

This system is rapidly losing convection. It's fast losing its golden chance to form. Cyclone1 (14:43 UTC -10/06/2007)


 * Yep, it's lost its definition. It's not forming anytime soon, but it's not really dissipating either. Maybe when (if) it gets closer to the Caribbean, then it might flare back up. Cyclone1 (18:57 UTC -10/06/2007)

Various statistics
I've done a little research and compared the 2005-2007 seasons first five INVESTs, depressions and named storms by date of INVEST formation.

2006 includes the unnamed storm as 2nd storm.

AT THE FIRST 93L.INVEST...

2005 (JUNE 13) HAD ONE ATLANTIC CYCLONE AND ONE EASTERN PACIFIC CYCLONE 2006 (JUNE 25) HAD ONE ATLANTIC CYCLONE AND TWO EASTERN PACIFIC CYCLONES 2007 (JUNE 09) HAD TWO ATLANTIC CYCLONES AND TWO EASTERN PACIFIC CYCLONES

AT JUNE 9...

2005 HAD ONE ATLANTIC CYCLONE AND ONE EASTERN PACIFIC CYCLONE 2006 HAD NO ATLANTIC CYCLONES AND TWO EASTERN PACIFIC CYCLONES 2007 HAD TWO ATLANTIC CYCLONES AND TWO EASTERN PACIFIC CYCLONES

AT THE THIRD NAMED ATLANTIC STORM...

2005 HAD 8 ATLANTIC INVESTS (97L BECAME DENNIS*) AND FOUR EASTERN PACIFIC CYCLONES 2006 HAD 8 ATLANTIC INVESTS (97L BECAME BERYL*) AND FIVE EASTERN PACIFIC CYCLONES 2007 HAD ? ATLANTIC INVESTS (CURRENTLY FOUR) AND ? EASTERN PACIFIC CYCLONES (CURRENTLY TWO)

– NSLE 07:16, 10 June 2007 (UTC)
 * 96L BECAME CINDY BUT 97L FORMED BEFORE CINDY WAS NAMED
 * COUNTS THE UNNAMED STORM


 * Nice research! Where did you find records of old 2005 INVESTS? Somehwere on the NRL? And also, it looks like 2007 is winning. Cyclone1 (14:43 UTC -10/06/2007)


 * Oh wow. We're AHEAD of the game this year?? Should fall back to normal though, unless we get some June cape verdes, which appears a possibility... -Winter123 04:03, 11 June 2007 (UTC)


 * We're one named storm ahead of 2005 now, if we get another storm before July 5 (when Cindy was named) we'll remain at least tied with 05. Cyclone1 (16:15 UTC -11/06/2007)


 * That seems suprisingly likely right now. Cryomaniac 15:30, 12 June 2007 (UTC)

I'm starting to doubt that, nothing is going on ANYWHERE in the entire ocean. Oh sure, they're talking about a barely noticable blob in the Caribbean over at Storm2k. I guess they're bored, too. I'm close to making that an AoI strictly to give us something to talk about. I might have to if it gets more organized. It's been trying to get its act together for a while. And there's that large blob northeast of the Bahamas, but pressures are really high and it's purely non-tropical. No waves, maybe the ITCZ will throw something at us soon. But now I'm rambling. Cyclone1 (02:58 UTC -14/06/2007) 02:58, 14 June 2007 (UTC)


 * Nevermind. Cyclone1 (22:37 UTC -14/06/2007)

AoI: Low forming in the NW Caribbean
You knew it was coming. It's just something to possibly watch.

From the TWO. A LARGE AREA OF CLOUDINESS AND SHOWERS OVER THE NORTHWESTERN CARIBBEAN SEA IS ASSOCIATED WITH A BROAD AREA OF LOW PRESSURE. UPPER-LEVEL WINDS ARE NOT FAVORABLE FOR DEVELOPMENT. 

If the upper level winds lighten up, then this will be watchable. Cyclone1 (17:43 UTC -14/06/2007)


 * Sheer should clear up by tomorrow if this thing doesn't move very far. (second panel) Cyclone1 (17:59 UTC -14/06/2007)


 * Yeah, 86W/17N is the spot to watch for weekend development. -Winter123 18:09, 14 June 2007 (UTC)


 * TWD says it's drifting north slowly. That means it's moving into more favorable conditions. 0_o (and it means I might finally get some rain.) Cyclone1 (18:18 UTC -14/06/2007)


 * It seems quite likely that this system will become 94L. It's quickly becoming better organized, and the majority of the models are hinting at it developing further into a Tropical Depression. We'll just have to wait and see. 71.7.209.70 21:54, 14 June 2007 (UTC)


 * Sweet! We need the rain here in Florida (still). And do you have the link for those models, please? Cyclone1 (22:13 UTC -14/06/2007)

94L.INVEST
Well, it's official. We now have 94L. Also, fifth INVEST of the year? What is going on? Cainer91 00:39, 15 June 2007 (UTC)
 * If this forms, looks like it could be the third storm in a row to effect Florida. Cyclone1 (00:50 UTC -15/06/2007)

CLOUDINESS AND SHOWERS OVER THE NORTHWESTERN CARIBBEAN SEA ARE ASSOCIATED WITH A BROAD AND ELONGATED AREA OF LOW PRESSURE. UPPER-LEVEL WINDS ARE CURRENTLY UNFAVORABLE FOR DEVELOPMENT...BUT MAY BECOME MORE FAVORABLE DURING THE NEXT 48 HR AS THE SYSTEM DRIFTS TOWARD THE NORTHWEST. AN AIR FORCE RESERVE HURRICANE HUNTER AIRCRAFT IS SCHEDULED TO INVESTIGATE THE SYSTEM FRIDAY AFTERNOON...IF NECESSARY. Cyclone1 (03:49 UTC -15/06/2007)

ACE calculations
Should they be done here or at Wikipedia itself? I know that Andrea's ACE was 0.00 (unless it regenerates as fully tropical), but for future reference or if Andrea becomes an actual TS, where should it be? CrazyC83 00:55, 12 May 2007 (UTC)
 * I don't see why not. We could give updates here on how the ACE changes over time as the storm progresses, whereas Wikipedia probably would just give the final "high" ACE value.  Galaxy001talk 05:31, 12 May 2007 (UTC)

I have created the ACE calculations at Forum:2007_Atlantic_hurricane_season/ACE. CrazyC83 20:49, 12 May 2007 (UTC)

Given that last season we linked to ACE calculations, we should keep them on Wikipedia. – NSLE 02:54, 16 May 2007 (UTC)

Andrea a kickstarter
After a month-long, worldwide storm drought, Andrea appears to have kickstarted the tropics. There's a storm in the Bay of Bengal and a TSFA in the West Pacific. -- SkyFury 14:58, 15 May 2007 (UTC)

- Whoa, really? I haven't been able to keep up with the other seasons aside from the Atlantic. Lilac DownDeep 19:08, 15 May 2007 (UTC)


 * There's now another TSFA in the South Pacific. -- SkyFury 13:36, 16 May 2007 (UTC)


 * They are both named storms now. In addition, there are two very distinct lows in the Atlantic right now, one of them, in the Bahamas, (which is very convection rich), is predicted to become a "gale" (we all know what that means). Here is an image of the low. Interesting? Just throwing that out there. Cyclone1 (23:06 UTC -17/05/2007)
 * That low is 91L now (see above). Gales are extratropical systems. --Coredesat 18:03, 18 May 2007 (UTC)
 * I know, but look at all the gales that were found to be tropical cyclones in post analysis. And there was the 2004 gale, which probably could have. Looks like this one is a lost cause anyway. Cyclone1 (21:07 UTC -18/05/2007)
 * Look as hard as we might, there are going to be some storms that will never be found, by anyone. There are probably more than three storms that have occured in the South Atlantic over the past forty years. Some storms pose as extratropical but really have a warm core and a closed surface circulation. Some of the ones we've found here on Wikipedia using GIBBS are interesting but impossible to prove whether it's a tropical cyclone or not. Part of the fun, I guess. -- SkyFury 21:43, 23 May 2007 (UTC)

And what fun it is! Cyclone1 (17:00 UTC -24/05/2007)

Hey, just wanted to join in! I'm a FL panhandle native, and I followed and made some anonymous posts to the 2005 hurricane season talk page, when I was living in Pensacola. My apartment complex was bulls-eyed by Dennis. In 2006 I moved to southern Louisiana, and do some recovery work on the side. I was planning to join the Wikipedia discussions then, but was put off when we had to get more "serious". I found the death of those talk pages to be greatly annoying, especially considering the extremely high quality of articles that resulted (the 2005 season article is really top-notch). But alas, I understand their rules. I'm REALLY excited y'all started this up...I've already joined in the betting pools, and hope this page stays active. I see some familiar names here from the 2005 season already...hope Eric is here too somewhere. I want to let you know my predictions for strong storms and bad locations (NC/NYC, strong Gulf Storm) aren't "hopes" by any means, but rather fears in a post El Nino year. Anyway, looking forward to an active discussion board, and here's hoping for the best and being prepared for the worst! Gulf Coastie 02:24, 1 June 2007 (UTC)
