*** Official 2014 Atlantic Hurricane Season thread *** / Now 2015 too (1 Viewer)

looks to me like it's getting it's act together.
My thoughts (guess) is I still think this is a TS that recurves out to sea. While some of the more reliable models have some chances of it hitting the OBX, I still think this stays well off shore. Maybe it becomes a Cat 1, but this will be way more fun guessing than actually forecasting in a couple of days.

I think we'll hit TD soon and TS within a day or so. Not sure it'll be much more than that but still feel pretty confident about no US landfall. Guessing more info from NHC soon.

 
New spaghetti model out. Again, all over the place. Still think this thing swings out to sea. But who knows.

Most every model (with 2 distinct exceptions) keep the cyclone away from the US mainland. (The CMC continues to track the system across south Florida – but this seems unlikely unless the system does NOT develop significantly for at least the next 72 hours – while the last OPNL ECMWF and GFDL model suite shows the storm first turning northward as the other major models do, but then suddenly turns the storm NW towards the Mid-Atlantic coast towards the middle of next week. However, the ECMWF Ensembles - which are typically much more reliable for developing systems - do NOT show this turn towards the coast.) Since the system has yet to become a well established cyclone, and upper level wind flow forecasts at these longer ranges during the warm season can be quite unreliable - all of these ‘outlier’ track forecasts remain highly suspect.
 
I do a lot of shipping to Mexico, so i monitor the Eastern pacific for work and the Atlantic for home.

To steal a line from Harry Chapin,http://www.nhc.noaa.gov/refresh/graphics_ep3+shtml/143302.shtml?tswind120?large#contents

"There are so many colors in a rainbow"

Glad I'm not on a vessel at the moment.
Saw an article yesterday talking about these two storms and how they could encounter the Fujiwhara Effect, which is when the two storms get close enough to start to rotate around each other. Pretty crazy. Would hate to be on a ship out that way.

 
Other than precipitation, it's really not that impressive at all. It's all over the place. Thoughts were that it would have started organizing by now. Instead, it's just a clump of shower activity.
Not talking about circulation, only about how it has begun to intensify in storm activity and getting a cluster of storms together versus where it was earlier today. The circulation will come soon. in fact it appears to be starting.

 
I think it's hilarious that the UKMET is still sending this guy into the GOM. Every other model has been bouncing back and forth, but not the UKMET. It appears to have gone All In on the GOM. :lol:

 
TS force winds but no real circulation yet so no advisories. Running across mountains tonight so maybe not much change overnight.

Aircraft reports
indicate that the system is producing winds of tropical storm force
over the open waters north of those islands, although the aircraft
data and surface observations indicate that the system still lacks a
well-defined surface circulation. Given the lack of a well-defined
surface circulation, tropical cyclone advisories are not being
initiated at this time.

I'm beginning to wonder when the turn starts. Better be soon or those models will start inching west. GFS has it heading north by about noon Sunday. Hope it's right.

 
buckle up Florida
Jacksonville, GA coast?
Right now it's a "who the hell knows" situation. When I posted that several of the models had shifted to Florida landfall (models run on 6 hour intervals and 6z might be fed different data than 12z causing changes). A forecaster I follow has been trumpeting out to sea and he's sticking by it. Euro model is out to sea (guy hugs that one). GFS is way closer to land. Official NHC has shifted west but is still relatively far off the coast. Now, several models see a stall coming. That seems to do 2 things. Has it go further west and possibly weaken as it's able to pull in cooler water from beneath the surface. Posted the "buckle up" because it seems like this one is being ignored because it hadn't organized well and they kept saying it was no threat to land. Now to me the chance of it getting near or making landfall in Florida is a little higher.

Forecaster at weather underground: All things considered, I must admit this is one of the more ‘challenging’ forecasts I’ve come across in my many decades of forecasting.

 
One thing to add. Haven't verified it but someone in comments on a blog said there hasn't been a GA coast landfall since the late 1800s. Hard to believe.

ETA: no major hurricane landfall since the late 1890s. There have been a (small) handful of minor hurricanes that made landfall in GA.

NHC:

However, there is significant disagreement inthe timing and sharpness of the turn...and

Given the spread in the guidance and the recent
formation of the system, confidence in the details of the track
forecast is lower than normal.

 
Today it looks like sharp turn north and out to sea is the answer. Probably will be so. On to the next one.

 
Once this thing turned in to an actual storm that the models could work with, the clear consensus became what a lot had thought : N, then a recurve out to sea.

97L is marching across the Atlantic now, too. It, of course, is going through the same Saharan Air Layer that 96L went through early last week. Looks like they are saying if it survives, Friday would be the day that it could hit favorable air for development.

There is also very strong wave situated over Africa that should enter the Atlantic soon.

Keep in mind, the next 4 weeks are the busiest of the Atlantic season, with the peak being right around September 11th.

 
97L is the one to watch right now. If, and that's a big IF, but if it survives it's way across the Atlantic, it does not (at the moment) look like there will be a trough to catch hold of this thing and spin it back out to sea.

It'll be about 5 days until we see if it survives, but if it does, the GOM is definitely in play. Way more so than with 96L/Cristobal.

 
So while everyone has been fixated on the Atlantic, it seems like there's something possible closer to home.

In the Gulf of Mexico, a weak cold front is kicking up some heavy thunderstorms in the Louisiana coastal waters. This activity will spread to the Texas coastal waters by Wednesday. With wind shear a moderate 10 - 20 knots, we should monitor this area for development. About 1/3 of the 20 members of the 06Z Monday GFS model ensemble showed some development in the Gulf on Thursday or Friday. (The GFS ensemble is a set of 20 runs of the GFS model done at lower resolution with slightly different initial conditions to generate an uncertainty "plume" of model runs.) The preferred track of the system was to the west towards Texas.
 
The more the day goes on, the more it looks like the next spot to develop could be the GOM. Eyes off of LA. Both spots wouldn't really see anything develop until almost Friday, so we'll see which, if either, develops first.

Well lookie here.
It was a joke. I read about it on Jeff Masters blog (guessing you did as well :shrug: ). I would put it in the "not worried" compartment. Assuming it will be over land before having a chance to organize. I see what he means about the GFS and the wave coming off Africa. That one could get big. Now fix your f'n mower!!

I don't think it'll be over land by the time it develops. I think it has a good chance of becoming something just before it crashes into Texas.

 
I see 97L did not make it through the night. Doesn't mean it couldn't still reemerge once it gets out of the dry air, but for now... RIP 97L.

 
So here's the problem that the former 97L ran in to. NHC is officially saying that 97L is done. But oddly enough, they are saying that in 5 days, 97L will enter favorable conditions (you can see those conditions in the pic right around the Lesser Antilles.) Once there, 97L will have a very good chance at strengthening.

So, to recap:

97L is no more. Dead. But "zombie" 97L could become TD5 by Friday.

I think as much as the focus is on 97L, the GOM is still the area most likely to develop into something AND affect the CONUS. It's a long wait until Friday.

 
If it's truly centered west of 90 degrees and if it's moving mostly west at about 10mph it should take less than 2 days to cover about 300 miles. The coast of Texas is around 97 degrees west. In that area a degree longitude is about 68 miles. So lets say 5 daysx68 miles and you get 340 miles. If all that holds up it should be on shore well within 3 days. Even at 5mph it will be 3 days. NHC gives it an extremely low chance of formation at 5 days. GFS shows nothing in the Gulf through Sunday. Just my own uneducated opinion.

My understanding is that it is not actually fully moving west yet. This is the cold front draped over the GOM. If you look at the satellite, pieces are coming off of the front and moving west, but the actual low would end up developing south of LA or a little more west. Again, I'm not saying this will happen. But this is the thought process of something happening.

 
There's also a wave that's still traveling across Africa that the NHC has given a 30% chance of development in the next 5 days.

GFS sure seems to think it will be something. By late Friday it's already a storm. This is a Sunday screenshot. http://i.imgur.com/j4fSE8D.jpg

Obviously no idea where it ends up or how strong it will be but for it to blow up that quick is troubling.

I haven't visited this thread in a long while. Imagine my surprise then to drop back in and find you all speaking a foreign language.

:lol:

Invests are areas that the NHC(edit to add National Hurricane Center) deems worthy of significant for development. They are not a TD (Tropical Depression) yet, but need to be watched. These are numbered 90 through 99 and end with an L. So right now, we have a Invest 97L that is no longer considered an Invest. If the one coming off Africa needs to be watched, it will be called Invest 98L.

In a couple of days, the old Invest 97L could need watching again. If so, it will get its old name back of 97L. If it developed into a Tropical Depression, TD's don't get names. They get numbers. So this would be the 5th TD of the season, hence TD5.

Other than that, shorthand was just being used. GOM = Gulf of Mexico and CONUS = Continental United States.

HTH :thumbup:

Looks like a lot of the major models have that very strong wave coming off Africa, turning into a monster hurricane and recurving out to sea. Barely makes it past Cape Verde islands.

Hope so. It looks to my untrained eye that it will become a major storm. Check out that video though. Could be a setup for funneling systems west.

I tried to watch it but I don't have sound. I watched the whole thing hoping I could figure out what they were talking about but couldn't .

:lol:

In a nutshell (and my interpretation based on what I remember): Oct 2012 weather over the Atlantic was similar to now. Rafael came and turned up north. That set up a ridge and building of low pressure in the Caribbean. Sandy formed and the rest is history. He's not saying we'll have a Sandy situation but does see long range models (>5 days) showing a ridge. Trade winds will be more "normal" with a westerly flow. Says to watch for stuff forming in the Caribbean and/or Gulf.

Interesting. Could make for a fun couple of months.

 
Tomorrow should be a fun day. Looks like a lot of activity going on all over the place. See how it holds up tonight. And then if it refires tomorrow when the sun heats things up.

Wrong thread lawnmower man.
Not the wrong thread. :confused: I was talking about all of the systems in the tropics.

You'll notice the area in the Gulf has now become Invest 98L. This could bring a lot of much needed rain to Texas. One thing about storms like this is once they make landfall, they're usually caught up in the jet stream and move back east. This can mean very heavy rains and flooding (queue Stevie Ray Vaughn) in Texas.

97L is still "dead", but it looks like that should change in the next 24 hours. Looks like the Hurricane Hunters have a flight scheduled to check the area tomorrow morning. Pretty crazy for a system that doesn't exist.

What will eventually become 99L should move off of Africa soon and still looks to be a beast. Although, models still have this recurving almost immediately. But, as we learned with Cristobal, models aren't all that reliable when they are modeling a system that hasn't formed yet.

Today should be an interesting day.

Figured you were talking about storms in general.

I have no interest. ;) (until that wave comes off Africa)

 
Looks like people along the Texas coast should start monitoring this pretty seriously.

Radar and satellite data along the offshore buoys and platforms indicate a surface low pressure system has formed about 150 miles south of Freeport, TX.

Deep convection has developed on the northeast side of the surface low in conjunction with low level speed convergence of an extremely moist air mass. The low is drifting toward the west at less than 10mph and should approach the middle TX coast early Thursday. Upper level winds are out of the SW over the surface system resulting in a shearing of convection off toward the north and northeast. Additionally, dry air in the mid levels is found across much of the central Gulf of Mexico which is limiting deep convection on the SW and S flanks.

Currently NHC is giving the system a 20% chance of development before it crosses the coastline on Thursday morning. A USAF recon. aircraft is scheduled to investigate the system this afternoon to determine if a tropical depression is forming.

With a defined surface circulation having now developed, this will result in some forecast changes.

Rainfall:
NE winds inland on the north side of the circulation are helping to draw drier air over W LA into E TX. PWS range from 1.5 inches north to over 2.0 inches along the coast. This will result in a strong rainfall gradient across the region today and possibly again on Thursday. Expect incoming rain bands along the coast to move inland to roughly US 59 or I-10 today and then fizzle out as they run against the drier air to the north. Rainfall amounts of 1-3 inches will be possible along the coast tapering down to less than .25 of an inch inland (north of HWY 105).

As the surface circulation moves to the middle TX coast on Thursday morning expect deep convection to develop on the N/NE sides of the low and this could be anchored across our S and SW counties from Galveston to Matagorda Bays. Could see some decent rainfall coverage and rates with this activity on Thursday morning, but once again it does not look to push very far inland of the coast…maybe I-10.

The surface low starts to become stretched out into a shear axis along the coast Friday-Saturday and this may be when the best chance of rain materializes for the entire area as deeper moisture is allowed to push further inland.

Winds:
Well defined wind pattern of low pressure over the NW Gulf has developed. NE has increased along the coast with Galveston (NE 16g23 mph) with the buoy 20 E of Galveston (NE 19g 23kts). Wave height at this buoy is 4.0 ft with a wave period of 6 seconds. Apache Platform south of High Island is ENE at 22 g 28kts. Wind profile plots at Galveston North Jetty and Pier 21 indicate a wind speed increase from roughly 12-14kts at 400am this morning to 18-22kts at 700am this morning. Wind direction is also backing from the E to the ENE and NE along the coast currently as would be expected with a develop surface low just to the south. Unless the surface low deepens more than expected should see coastal winds peak in the 20-30mph range today and early Thursday.

Tides:
ENE to NE winds will start to push water toward the coast. Pleasure Pier ran just over 1.0 ft total water level at the high tide this morning and Sabine Pass was a touch higher than that. ENE to NE winds will continue to push water today the coast today into Thursday and Friday with low pressure S and SSW of the upper TX coast producing an onshore flow. Current water levels are running higher than predictions, so not sure how accurate those predictions are looking out of the ET surge guidance using the GFS pressure fields. Appears there was a nice bump in the surge last evening of about .50 of a foot which has pushed the total water levels up and over a foot this morning. Still not expecting any overwash with these levels…really need to get up around 3.5 feet or 4.0 feet for problems to begin. With the 20E GLS buoy showing a 4.0 ft swell with a 6 second period that is not too much wave action heading for the coast…but offshore winds are increasing and swells may get up around 4-6 ft by this evening.

Will update again if needed today per USAF mission (if it happens) or any changes in the organization of the tropical system over the NW Gulf.
