Title: Hurricane Central 2010
Post by: UC Davis Meteorologist on May 20, 2010, 02:29:17 PM
Note to Moderator: Please pin this!

Because of the delay, of the NHC forecast predictions of the 2010 Atlantic Hurricane forecasts, I decided to make an offical thread where you guys can discuss/post tropical activity updates mainly in the Atlantic and Pacific.

**************WELCOME TO THE OFFICAL HURRICANE THREAD ON TWC TODAY******************

Without further ado, I will take the liberty to post the Atlantic and Pacific Names that will be used this year,

Yes. Any organized storms or potential ones will have their own discussion. Including: Invests, subtropical storms, tropical storms and of course hurricanes.

Because it's unusual for tropical waves to be coming off the coast of Africa in June, it's more typical from mid July onward.

Record SSTs in the area off the African coast with not too much shear. Juicy area for development.

Post by: toxictwister00 on June 03, 2010, 06:43:38 PM
I think dust has hindered it's development temporarily while coming off the W. African coast, but it might be heading into more favorable area since the dust is not that big of a deal that far out.

If this disturbance develops soon, it'll be in a relatively unusual area. Also, I don't think it looks as well as it did yesterday.

The pressure seems a bit high for it to be Alex, but it definitely looks formidable! :D (Who knows? It might be TS Alex in the Gulf and weaken to TD Alex by that image.)

EDIT: After looking at the GFS wind models, the winds on the outside of the storm will be around 25 knots. That makes me think the inner winds will be 30 to maybe 50 knots. If we go above 40, we have Alex. Really doesn't look that greatly organized, though.

Your right, it doesn't look very impressive except for the QPFs which increased on the 18z run, but the low is weaker and it's 2 days faster.

I went on the NHC's website, that one looks fairly healthy. It might mean some serious business if it can get more organized. Dry air is no problem and wind shear isn't too bad.

Sorry for double posting, but I saw another map from the link of the site I posted of wind shear over the next 24 hrs. Wind Shear should be fairly light and decreasing in a lot of areas in it's WNW path. We might actually get our first named storm of the season.

Haha, the 12z GFS wants Savannah,GA to get with a Cat 1 hurricane between the 28th - 30th this month. :lol: This would make the Farmer's Almanac accurate about their prediction of a hurricane threat within the latter part of this month. I love that the models are showing these hurricane possibilities it's really getting me pumped up!

16th-19th. Thunderstorms Tennessee east to Carolinas, then clearing.
20th-23rd. Scattered thunderstorms.
24th-27th. Hurricane threat.
28th-31st. Scattered thunderstorms.

Well, I know that people really don't want hurricanes, and this is a pretty stupid wish, but I really hope the season starts getting active now and we see some strong hurricanes soon. It's really fun to watch where they are going to go, and even though TWC will have a huge fit over any hurricane of any strength, I'm getting a little tired of these small, short-lasting storms during a "hurricane season that is supposed to be as active as 2005." Wouldn't that really be something if these predictions were totally off. :wacko: But I know we are now just reaching the "peak" of hurricane season, so hopefully we'll get some activity soon! :D

Thanks for providing the models, Tavores...they look really interesting. :thumbsup:

You're welcome and I agree, I don't want any of those things either. I just want something to form so there can be something to track worthwhile. Also the 18z run of that model I posted has a completely different track (which I knew was gonna be the case this far out anyway) has the same hurricane only stronger at 974mb IIRC would be major hurricane strength scrapping by New England.

It stands for Global Forecast System, and it's one of the most useful numerical weather prediction models out there.

It's a type of hurricane model
No, it was actually designed to be a mid-latitude synoptic-scale model.  It wasn't originally meant for the tropics or polar regions, but they expanded it to cover the globe.  You have to be a little wary when using it in the tropics as it doesn't have all the physics packages put in specifically for there.

Its a crappy model for the tropics but when you start getting a number of large storms on its runs, its a sign things are improving for tropical development. If you ever need a laugh look at the GFS past 100hr or so :P

The 2010 Atlantic season may seem like a dud to most people in the United States, but it's officially an above normal season already despite that we still have over two months to go.  We've had 11 tropical storms and 6 hurricanes to this point, which is exactly at the normal climatology values.  We're only supposed to have 2 major hurricanes in a normal season, but we've already had 5 so far.  What's really impressive is that 4 of those 5 major hurricanes reached Category 4 intensity.  That's not a ratio you see too often. :blink:

I think the very slow start combined with the promise of a busy year is what got people confused.  Even I was becoming rather sceptical.  However, the past month or so has been absolutely madcap in the Atlantic, and there's yet another wave coming off the coast of Africa...

The "activity" level of Hurricane Season seems so hard to describe. :thinking: Some people might say "Oh yeah, I told you so...the 2010 Hurricane Season has been very active" because there have been so many hurricanes while others state that since no major hurricanes have made a direct hit on the US, the season hasn't been "active."

What I think we can't do is compare this Hurricane Season to that of 2005 (yet, anyways) like people were doing at the start. :no:

Seems there's a tendency by the general public to judge a tropical season by the number of landfalls. A busy season doesn't equate landfalls nor does a slow season mean no major impact. So far this year, the coastal U.S. has been spared. One of the slow seasons (1992) delivered one of the most memorable and expensive hurricanes on record: Andrew.

Although in fantasyland, Tampa, it could happen on October 5, 2010 with a possible Cat 3/4 hurricane. :fear:
Thats 95L if it ever develops. I believe the GFS is full of BS

I don't think that's true, GFS has been doing a good job at sniffing out storms in the long range, it's just the track and intensity that's usually BS.  :P Also 18z run still is showing a FL hit near Tampa, but weaker around 975mb

Just a quick update on the hurricane season, for September 21st.

Hurricane Igor has become post-tropical, according to the National Hurricane Center. Even then, it is packing winds of 80 mph as moves towards Greenland, NNE at 39 mph. Wind speeds are expected to be hurricane force throughout the next 36 hours.

Tropical Storm Lisa is slightly strenghtening west of the Cape Verde Islands, moving N at 2 mph. Sustained wind speeds are 45 mph, and are expected to increase to hurricane strength within the next 36 to 48 hours. Lisa should continue tracking north until it hits what I can only guess is the ITCZ, at which point it will track steadely westward. Although not a threat to the U.S. at the moment, this system should be continously monitored.

And finally, Tropical Depression Georgette is still impacted Baja California, with sustained wind speeds of 35 mph. The storm is still tracking due north at 10 mph. Arizona may get some well-needed rain from this system. I haven't heard any reports from Baja Califonia yet. Have any of you guys?

Finally, there is a disturbance in the caribbean that deserves some serious attention. A group of slightly organized thunderstorms are slowly moving west-northwestward and have been given a 50% chance of developing into a tropical cyclone within the next 48 hours. If it does form, we can welcome Tropical Storm Matthew to the 2010 Atlantic Hurricane Season.

So far this year, we have had 12 named storms, 6 of which have become hurricanes, 5 of which have attained major hurricane status at some point in their lifespans. Percentage wise, this means 83% of all hurricanes this year have attained major status.  If I am wrong, please let me know.

I'll try to post an update sometime Thursday, if it is okay with the administrators.

AFD MLB Florida

BOTH GFS AND ECMWF CONTINUE THE TREND OF
SHOWING A BROAD AREA OF LOW PRESSURE REMAINING OVER THE NW
CARIBBEAN EARLY NEXT WEEK...THEN DEVELOP A TROPICAL CYCLONE AND
LIFT IT NORTH ACROSS CUBA MID TO LATE WEEK IN RESPONSE TO EASTERN
U.S. LONGWAVE TROUGH. IT IS UNCLEAR IF THIS SECONDARY DEVELOPMENT
IS REGENERATION OF TC MATTHEW OR A SEPARATE SYSTEM (NICOLE?).
SYSTEMS CAN BE SLOWER COMING OUT OF THE CARIBBEAN THAN MODELS
EXPECT SO HPC BRINGS THIS CYCLONE ONLY TO THE WESTERN TIP OF CUBA
FRIDAY MORNING. MEANWHILE... AT THAT TIME...GFS HAS IT JUST OFF
THE SW FL COAST AND THE ECMWF IS JUST OFF THE SE FL COAST...BOTH
LIFTING NORTHWARD. THERE IS GREAT UNCERTAINTY AT THIS TIME
REGARDING THIS FEATURE SINCE IT MAY NOT EXIST YET SO CONFIDENCE IS
QUITE LOW IN THE EXTENDED FCST.

What do you think... will Tomas be the last named storm in the Atlantic this year?

I'll guess no. Remember T.S. Zeta in late December-early January 2005/2006? Another storm may or may not happen but it's been a busy year.

I think there will be one more before it's over.  Everyone seems to forget that November 30 is the end of the season, and that date has been broken several times.  For the Atlantic during 1851-present, at least one tropical storm has existed in every month of the year, and at least one hurricane has existed in every month except April.

I've removed the poll and changed the subject titles so that everything is now fully merged.  Anyone can continue the discussion about if this season is finally over here.

And the purpose of this exercise was...?  If I'm not meant to make polls, then please just tell me.  I made a poll, it got moved, people didn't like the move, and now it's gone.  I'm entitled to be a little unhappy.

You're welcome to do polls in their own topics.  Unfortunately, Martin thought your topic didn't really belong by itself.  Once your topic got merged into this general thread, the poll became out of place and confused other members.  Sorry about the issues. :hmm:  I'm going to talk to Martin about figuring out what to do here.

Oh dear. I just thought it would have fit in the general discussion better. I mean you could make a topic for every storm about "Will X storm be the last? " I didn't  mean to upset anyone.

It's looking like we're just about done for this season.  Nothing has really formed since Tomas dissipated.  A full summary will be provided if we reach December 1 with no changes.

As promised, here is my full summary now that the hurricane season is long over.  Some of the information I gathered from various sources like NHC, AccuWeather, and Wikipedia will really surprise you:

The predictions of La Niņa creating an extremely active Atlantic hurricane season all came true.  Amazingly, not one single hurricane made landfall over the United States this season.  Just two tropical storms directly struck the coastline, Bonnie and Hermine.  Since 1900, there had never been a season that featured at least 10 hurricanes where zero of them made landfall over the United States until this one.  Stop and think about that factoid for a moment, and realize that we're going to pay in the coming years for being so lucky.  In terms of activity, I'm expecting all indicators to place this season in the top five.

2010 Atlantic Hurricane Season:

19 Tropical Storms (tied for 3rd most with 1887 and 1995)
12 Hurricanes (tied for 2nd most with 1887 and 1969)
5 Major Hurricanes


Meanwhile, La Niņa made conditions very unfavorable over the Eastern Pacific, and new records were established for lack of activity this season.  The last storm dissipated on September 23, which set a new record for the earliest date ever that this basin had ended any activity during a season.  It also set new record lows for the number of tropical storms and hurricanes.  It just amazes me how negatively correlated the Eastern Pacific is to the Atlantic.  When one is very active, the other is practically dead quiet.

2010 Eastern Pacific Hurricane Season:

7 Tropical Storms (fewest ever recorded)
3 Hurricanes (fewest ever recorded)
2 Major Hurricanes

Nice, very detailed! This was a very active and interesting season although we dodged almost all of them, which caused this to make the record books. I was also amazed at how large Igor became (the largest recorded in Atlantic basin). Is this being shut down 1/1/11?

Thanks, Mike!  That date sounds about right, but Martin and I will also consider the activity of this thread before closing it down.

Update:  It's been months since anyone has touched this thread, so I've locked it for good.  See you next season!
