Dennis (#9)
Posted by: Andy Location: Massachusetts
Posted On 09:53AM 26-Aug-1999 with id (RQVNQVTNRTXNRPU*)

One thing that seems to be underemphasized here is that Dennis has been and continues to be greatly sheared by west to northwest upper winds. This has not been anticipated (or initialized?) by the models at all. Where is this model error coming from? What effect does this have on Dennis' steering? Why are we sure it's going to lessen? Thanks....

Looking at the situation with Dennis this morning, the trough over the eastern U.S. still may have enough punch to pull Dennis northward, but, then again, Dennis may move slow enough to continue west-northwesterly. I would have to place the chances of a Florida brush/strike and a northward turn both at 50%. Satellite imagery looks scary, though, as Dennis seems to be steadily moving west-northwest with no signs yet of a northwest curve. I don't like how the NHC is wording the threat in their public advisories. They are telling residents of primarily the Carolinas to watch out, but any storm of this proximity to the Florida coast should warrant more concern that I have seen. Since unsuspected wind sheer is affecting Dennis presently, I don't foresee him gaining more than Category 2 status IF he moves toward Florida.

I have monitored this storm, like others since I was slammed by Andrew 7 yrs. ago from the other day. Dennis appears to be struggling to intensify because of the Northwesterly winds aloft sheering off its' higher cloud tops. However, if this trough in the east does not dig deep today, and lifts back up to the north prior to Dennis's expected NWerly movement, I believe a strong High Pressure (Bermuda High) could build in the Atlantic pushing Dennis not only Westerly, rather than Northerly, but if it builds in strong enough, it could certainly cause the storm to slightly wobble southerly, vs. WNWerly.??
dennis strength (#12)

Category 2 seems a little weak for my tastes. The shearing is happening now. If it persists, then yes it would have a hard time strengthening.
But you have to look at the warm waters in the Bahamas. They say it is warmer there than ever before. That will make the storm grow. I think once the storm leaves the shear zone — and that zone is not too strong right now — the storm will boom. Look at what happened with Andrew. When it hit the Bahamas and the gulf stream, it blew up. I see a similar pattern happening with Dennis, maybe even a greater growth pattern. It won't come close to Andrew's strength because it has a lower starting point.
Dennis WILL turn (#13)

My thinking has NOT changed from yesterday. It will get kicked up north before any direct brush with Florida happens. I'm 75% sure of this.

Mike is going by the BAMM which I don't particulary trust in the situation. I'm going for the turn to the north.

Again if my thinking changes on it, I will post here ASAP.

where is everyone? (#14)

It's been more than three hours since the last posting. Where is everyone?
Big question: Is the slowdown since the 11 am advisory the turn or just another bad sign for florida?
little question: doesn't the water vapor images look like the trough has sunk further south?

I am hoping that the slow down means a turn to the northwest ...doesn't it usually slow down when it turns? Anyway, I am more hopeful now than I have been in the last few days that it will turn. I haven't looked at the WV images but I am going to go check it out. Keep hoping Florida!!!
The trough and Dennis (#16)

Posted On 04:27PM 26-Aug-1999 with id (RPWNVYNRUTNQSQ*)

Well, after analyzing the situation this afternoon, I will shift back to my earlier forecast of Dennis taking a northerly turn and sparing Florida. Infrared satellite imagery shows an elongation and flattening of the western quadrant of convection. This occurrence indicates that Dennis is being influenced by westerly wind shear from the trough over the southeast U.S. Since Dennis is in an area of very weak steering currents, any possible steering entity, regardless of strength, will be enough of a factor to move Dennis in the resulting direction. The weak entity in Dennis's case is the trough over the eastern U.S. As for strength...the wind shear mentioned earlier will likely keep Dennis at minimal Category 1 strength for a while to come. I doubt that Dennis will intensify at the rate that NHC is forecasting.

As a final note...it appears doubtful to me that Dennis will directly impact Florida. I really don't see any reason why Dennis will escape the effects of the trough; however, I urge Floridians to stay on guard. The only possible way that I see Dennis directly affecting Florida is if the storm weakens and thus does not become influenced by the trough as much.

I've been away all day and had no idea what was going on only to come home and read everyone's comments and then see the 5pm advisory, he's stalled again. Waiting to hear new thoughts on this storm. One TV weather Channel here saying we are out of the woods!

sorry about that. I was wondering how long it would take the bermuda high to set in, and if it would be strong enough to pull Dennis into florida
dennis quiet far north (#19)

Hello evryone i have read the position of dennis
it seems a fairly further north then yesterday.
I im starting to feel better for i think becuse it is futher north it will queit likely miss florida and move north as predicte.

I was wondering what evry one thought about this.
{PLEASE REPLY}

I,M REALLY BAFFLED BY DENNIS I DON'T THINK DENNIS KNOWS WHERE HE IS GOING AT THIS POINT. I WOULD REALLY LIKE TO HEAR WHAT MIKE HAS TO SAY NOW. DO YOU STILL STICK TO YOUR PREDICTION ON DENNIS?

Well i have been reading the posts in the room and it sure seems like the room has given DENNIS the fair well, Well im back to tell you that nothing has changed all day, if you call a 6 mile move in a day something than you need to sit this pne out, Others have asked why i have not posted well i have been real busy all day long, Now what am i thinking , THE SAME, i will give you all a piece of info that might help , today i talked to former hurricane director DR Neil Frank out of KHOU-TV in houstonon the phone today, the conversation went as follows, He talked about DENNIS stalling and putting florida in a threat, he also said that the system was stuck between the trough to the west and the low level east flow to the systems east, he said that DENNIS was starting to win the battel, as the southern end of the trough was showing signs of degenaration , and that a possible watch could be put up along the florida coast from miami to daytona, last we chatted about the possible track of cindy , helping aid DENNIS west, as she passes to the north of him het out flow and ridge following in tandum with her could help establish the western flow again also pulling the low north and off the maine coast, again this was my day im interested in hearing from you all now, Mike Anderson Florida WX>
Quiet (#22)

It's gotten awfully quiet out there. Trough forecast to hang in there, maybe dig in deeper over the weekend, and will probably take Dennis northward eventually. Dennis has been hanging tough all day, with shear continuing, but it almost seems to have anchored itself in the last satellite loops, not budging further west than 75W and not going north of 25n. Even with all the models in agreement as to path and eventual strength, it's going to be interesting to see how this all plays out. Dennis is stubborn and I wouldn't raise the all clear flag yet. .Anything can happen. Let's hear some chatter out there. Also, any thoiughts on Emily? This still may end up in a similar position as Dennis if it survives. Also seems to be a twist further out in the east Atlantic south of 10N. But back to Dennis. Any thoughts?

Interesting, very interesting, what i am talking about is what Dr.Neil Frank had to say about dennis. I have been thinking the same as well,and the fact it came from Dr.Neil is interesting as well. i have always trusted what he had to say this new guy Jerry Gerold seems to be running the nhc diferently becuse the nhc has been pumping all sorts of BOLOGNA.


The models Do not matter-Much (#24)

I have noticed the NoGap model tonight and I have observed the outflow from Dennis on both the Ir and the Water Vapor It appears to me that even if Dennis makes no landfall as far as the eye of the storm is concerned, if Dennis gets as close to Florida as the models are forecasting, and moves only 6 miles per hour, Florida is gonna drown in rain. Flooding and coastal beach erosion is still quite likely even if no one needs to actually evacuate because of storm surge. However, the longer Dennis sits in one place, the more time he has to build into an awsome phenomenon.
Dennis and the Future (#25)

I have to say that Dennis is quite a pain. What did Neil Frank have to say about the westerlies that were starting to affect the western side of the storm, Mike? Seems to me that it was pretty much inhibiting any development of Dennis today/tonite. As for Jerry Jarrell of the NHC, I have to say that they must be very confident of the track because after Andrew they would be taking a pretty big hit government/publicly wise if they didn't put up watches/warnings in time for people to get out of harms way. I think I remember last year with Bonnie everyone was asking the same questions, with the NHC being very confident (and correct, I might add) of that track. So at this point, I have to say....they better be right. Also, one other point I would like to add: if the Emergency Management/Government of Florida thought there was a serious threat (and there might be down the road) I think they would have the authority to issue watches/warnings if they thought it prudent. Of course, I could be wrong. But I don't think they would mess around. Thoughts?

Well, I am still sticking with my forecast of a northerly turn. The trough looks very formidable on water vapor imagery this evening and I see no reason why it will not turn Dennis northward. Steering currents over Dennis are obviously weak and, whatever the intensity of the trough, it should be enough to pull the system northward. I am also sticking with my intensity forecast. Dennis will remain a minimal hurricane for quite some time to come until it moves farther northward when conditions may become more favorable for strengthening. If Dennis somehow finds a way to the Florida coast, he will continue to be adversely affected by the shear and intensity would likely remain inside Category 1 strength.

As for Jerry Jarell, I would not bash him any. I, myself, don't see any bologna coming from NHC. How can a probable turn northwest and north be bologna?

TENNIS DENNIS IS THE BALL (#27)

Posted On 10:33PM 26-Aug-1999 with id (RPUNQXXNQYSNQWQ*)

I want to say that i am not impacting the florida coast with this system i am saying again over and over again a BRUSH, i am expecting that DENNIS will get his act together and spread out a bit more than he is now, it is in no way impossible to see a 100mph hurricane have tropical storm force winds reach out 150 miles, now even given the track it still has him 78.4 longitude not that i think he will be there at the time the models and NHC are thinking , but if you have a tracking map handy look at that position, that is in no way 200 miles from the florida coast, BRUSH even if he ends up at 77.5 he would brush the coast, so RON i want tio hear from you seen that you are going with the trough thing, and Ron what will you say if DENNIS sits and the trough moves out ,and as far as the secound punch im also seeing it and i think it will get caught up in the low that is heading up through the NEW ENGLAND area and should be off the maine coast by tomorrow afternoon, Mike Anderson florida Wx

Well folks i have to tell you that im now getting ready to impact florida in a big way based on the latest GFDL and the BAMM,BAMD are all now takeing DENNIS to the florida coast.

Frankly, I am tending to agree with Ron. I don't believe that Dennis will broaden out until it moves north of the central FL area AND the wind field due to the shear is restricted to the eastern and northern quads with this system. Remember when Bertha approached in 1996, we were told to get off the beach in Indialantic and we never got a breath of wind. I do believe, however that we shouldn't let down our guard on this one because its drifting again to the WNW, and anything can happen.
