So Miami you are saying that the Fat Lady is warming up and about to sing to 95L

95L's circulation will be coming onshore within the next hour or so, and no development will take place in that period of time.

I dunno, Tim....Highest winds I could find (metars in GRL3) around 95L were 8kts in NOla *shrugs*

Land friction going to spawn some pretty strong thunder storms from 95L looks like Houma might get caught up in some of that train effect tonight and in the morning
hope it don't last to long.
East of houma to.

One thing is for sure, florida has had some serious rain and more is on the way, never had this much so early in the season.

4198. Moving pretty fast in that last radar loop - high top must have caught a faster, northerly flow and decided to scoot on towards shore.

I sped up the frame sequence to Warp,,to show the unattached Synoptic Clarity for the Eyeball challenged

annnnnnnd......9kts in Houma w/29.88 Falling

now I don't think we should downplay 95Ls impacts on the areas it is affecting

It is impacting the oil spill region and the heating of the day will give you guys in LA a nasty weather day.


However in terms of whether 95L deserves to be a TD or TS, IMO it does not. It was always attached to the front, now it is not but it is about to make landfall.

That being said, sometimes even the invests can have a significant impact on land

Coastal Flood Watch

Statement as of 12:04 PM CDT on July 05, 2010

... Coastal Flood Watch in effect from late tonight through Wednesday
afternoon...

The National Weather Service in New Orleans has issued a coastal
Flood Watch... which is in effect from late tonight through
Wednesday afternoon.

The combination of high astronomical tides... above normal water
levels... and increasing southeast winds will give the potential
for coastal flooding around high tide Tuesday morning and
Wednesday morning. The threat for coastal flooding is higher with
the Wednesday morning high Tide.

Water levels are currently 1 to 2 feet above normal. Tuesday
morning high tides are generally between 7 and 10 am CDT. Tides
may reach 2 to locally 3 feet above normal values.

Wednesday morning high tides... between about 8 and 11 am
CDT... are expected to run 2 to 3 feet... and locally higher... above
predicted astronomical values.

Precautionary/preparedness actions...


Flooding may result in water covering roadways and low lying
property around high tide in coastal areas along the Mississippi
coast... and near tidal lakes... outside of hurricane protection
levees in southeast Louisiana.


A coastal Flood Watch means that conditions favorable for
flooding are expected to develop. Coastal residents should be
alert for later statements or warnings... and take action to
protect property.

Not it wasn't. That image says August 3rd. On August 3rd his peak intensity was 40kt.

Prior to landfall,it met all the "tropical" criteria
except for the NHC acknowledgement.

Actually, when 96L ramps up, the movement will be more poleward....

I think it will be a northern gulf coast event..cat 2 or perhaps stronger. need feedback on the gulf conditions in 3-4 days. if we have a nice ridge, and moist air....explosion city!

Still never had sufficient organization.

.

It has absolutely not met all the criteria

take a look at the convection current with 95L, it is certainly not persistent nor strong enough for classification

whether it is classified or not is irrelevant at this point

As I said earlier, 2 foot water rise in Baritaria Bay has occured as a result of the Southerly Flow associated with 95L. Infact, the water has inundated peoples yards outside of the levee protection system.

Quoting MiamiHurricanes09:
There is no doubt that if 95L were not attached to the frontal boundary it would be a tropical depression.

I doubt it. T1.0 is not sufficient organization.

Then again, the fact that it attached to a frontal boundary deteriorates satellite appearance, thus Dvorak numbers are greatly impacted or reduced.

Quoting extreme236:

I think some area losing judgement on what does in fact qualify a system for classification of a TD or TS

95L has always been attached to the front and has never had sufficient organization or persistence to get upgraded

Again at this point, whether it is just an invest or a TD is of very little meaning, impacts will be the same either way

Itsa, Itsa,.Itsa..

Itsa Raining and the winds a blowing some.

pffffth..

rather than childless bickering amount whether 95L is this or that...let's just follow the thang.....look for a possibility it will travel east along the coast.....lol lol lol....
then ramp up to a depression or TS.....

Quoting hunkerdown:

You'd have to give it a T# of 2

Still attached to the frontal boundary, but looks like a TD.

Very true. But what I previously meant is that if 95L wouldn't of originated from a frontal boundary, or if the frontal boundary wouldn't of come into play that 95L would've become a tropical depression.

Nonetheless, 95L does look better organized, but it's just out of real estate.

95L warm core

I can see the red Warm front in between the Clouds outside..

Pfftth..LOL

Patrap, is it raining 10w40?

I the COC arond 17 n fizzled the last couple hours. Looks like something is trying to take over around 85 w 20 n, but I'm not seeing a COC anywhere at this point - just a broad general circulation with eddies all over the place. I'm currious if something will take over on that burst of convestion that we're seing around 85 w 20 n? Check out the shortwave view on floater #2. Notice the circulation that gets stretched out east/west around 17 in the last few frames. I think this thing will develop once it finds a center, but with all those eddie circulations, it keeps fighting itself.

Nothing really worth watching IMO. Just a couple of weak systems with no chance of becoming much more than a bad afternoon thunderstorm.

right now I see the true COC of 96L near 17.5/6N 83.7/8W

At this point 95L is producing widespread heavy rain, gusty winds & water rises along the LA coastline.

The main reason why we're watching 95L so closely is due to the potential impacts on the BP oil spill area, LA, MS, AL, FL impacted by wind/tide driving oil onshore.

Hopefully this feature will move onshore and dissipate quickly so the BP clean-up can go on unhindered.

Can we please end all discussion/bickering about 95L which soon enough will be onshore and therefore no longer a threat to develop. 96L is much more of a concern than 95L will ever be as it has more of a chance at becoming a significant player in the next few days as it becomes better organized and has much more time over water than 95L has.

4240. OK it's a warm core Low attached to a stationary front. Hopefully this moves inland quick, before it sheds the stationary front & creates major problems.
