Ophelia not budging

By: Dr. Jeff Masters , 9:12 PM GMT on September 07, 2005

Long range radar out of Melbourne this afternoon showed a significant improvement in the organization of Ophelia, and the pressure fell modestly from 999 mb to 996 mb. However, the winds have are still at 50 mph, and Ophelia has not intensified quite as fast as the improved radar presentation would suggest. Upper-level winds over the south side of the system relaxed to the 5 - 10 knot range this morning, but have increased again to about 10 knots. These winds are causing shearing on the south side of Ophelia, and so there is little deep convection there. Ophelia is over warm 29 - 30C water, and no significant increase in the shear is forecast the next 36 hours. This should allow Ophelia to approach hurricane strength by tomorrow night or Friday morning.

I have no additional speculations on her future track. Steering currents are very weak, and there will certainly be plenty of time to speculate on her long-range track the next five days while she wanders within 100 miles of her current location. I don't think Ophelia's winds are strong enough yet to stir up enough cold water and cause weakening. Hurricanes need water of at least 26C to maintain their intensity, and water this warm exists down to a depth of 75 meters over the waters east of Cape Canaveral. Winds of tropical storm force are not strong enough to churn up water from deeper than 75 meters.

Yesterday you said the GFS was the superior model. Today you note how bad it was with Jeanne last year. The GFS is the worst performing model. Take Katrina for example. GFS didn't even have Katrina on the map 3 days before developing, even as it's energy was there and moving NW towards Bahamas. GFS also had forecast of Katrina going up East Coast for over 72 hours on it's runs. So your comment yesterday about GFS model being superior was just a plain stupid comment. You should do some case studies on how bad the GFS performs. I can supply you with case after case where the GFS is always wrong because it cannot deal with heat and feedback situations.

ah, she is closer to me...crazy, the 11AM and 8PM had her at the same coordinates yesterday...she is meandering off the coast, they believe we will start to feel some good winds this PM.

We've got bad erosion here as well. I'm affraid that this thing will strengthen, loop back around, and come back at us. I think she is going to do what jeanne did last year. Even here we had winds of 80+mph with her.

Yep the thing that concerns me alittle is if it moves away from the coast a bit and sits and loops..Conditions might become alittle more favorable and then it comes back to the coast..Who knows we will be talking about this for awhile..lol..But unfortunatley they were just about done putting back our beach here and now it is getting eroded again..big chunks already going away..that is what is going to be bad here.

We're running out of goats to sacrifice here in Jax. Looks like we'll have enough to keep the storms away another year. :D

weatherguy, we've had rain off and on during the night and morning. I saw that dry air, and it still looks like there is some shear from the south

Definately weatherdude..I am here in St. Augustine and what a diference when i woke up this morning..Our gust here have been between 30 and 35 mph consistently now, unlike yesterday..Not too bad..but definately different then yesterday..But still its a dry storm..not much rain..Satelite looks terrible..Some of that dry air got mixed into the storm, but if it can mix it out we may see alot of rain today. It is still slowly getting stronger, so who know..we will see today.

good morning everyone....well, here we are, and there sits Ophelia....still. I'm near Cocoa Beach, and I can tell that she has gotten stronger as we have stronger winds today and the low level clouds have increased considerably.

Good morning all! Sitting here in Tampa and watching Ophelia do absolutely NOTHING! I wish she would make a move in one direction or another. I see the new model runs still resemble a lie detector test gone wacky.

That is because of a bit of dry air,convection is limited to near the center and to the northeast.

The clouds west of the Yucatan Peninsula look better than Ophelia looks right now. Slow development possible with it. Probably heads into Mexico/lower Texas.

If it moves into the gulf,I pray that it will quickly move north into the eastern panhandle.

The lates NHC forecast disscusion seems to be hinting now at more of a loop rather than a track out to sea.It has been drifting slightly to the south and southwest at at around 2 and 3mph since around midnight.

Batten down over there in eastern Florida!
Those of us in the panhandle are hoping you get a break from all the rain and Ophelia leaves you alone! (paticularly since we don't want to see it coming across at us, LOL.) Gotta go to work!

The storms size of convection is a bit small for the moment but that is because of some dry air to the southwest has gotten in the storm a little bit,but a fairly large eye seems to be forming,but as you can see the storm is fairly large but dry air from the southwest is limiting convective coverage at the moment.That was the case with jeanne at first,most of the covection was limited to near the center at first becuase dry air,but when the dry air works out the storms convection covergae will likely expand alot,filling out the circulation.

Good Morning Florida!

As no one has a clue what Tropical Storm Ophelia is going to do we all MUST STAY VIGILANT & prepare for the worst!

Do Not make an plans based on amature posts on this website.

Remember for those who live in low lying areas or in mobile or manufactured homes.. hotels are occupied by refugees from the Gulf coast so your regular may be not available. This will also cause more traffic as we scramble to find a safe place to stay. Get provisions early & avoid the rush & empty shelves.

Stay safe & enjoy the weather soaps!

Hold on Lefty. Did you see a jog to the ene in the last radar image? If so that could lead to stregthen as she could get a little further off the coast.

You know I think the problem with TWC is that they are mostly tranlaters. Put the weather in laymans terms. That's it. The lady just on stated in the tropical update that O still looked pretty ragged? I mean come on. They need to give these people a little freedom. At least the ones feeding the teleprompter the info they read.
