The flags in question for Quiksat relate (primarily) to rain contaminated measurements vs non contaminated. Quicksat readings are 'contaminated' by rain and are therefore unreliable in those cases, for wind speed readings.
NHC and the analysis agencies much prefer to use unflagged (uncontaminated) sectors for wind readings.

This is a very short and truncated explanation of this quality control parameter...anyone else wants to jump in, feel free!

Harvey looks pretty good on visible this morning.... ULL looks to be weakening some, Not a threat to US except the shipping routes in NE atlantic.... The wave near 12n and about 28w, i think could be the next area of interest for the atl. Nice flare up convection this morning. Been holding together since exit off the cape. We will have to see. Should continue moving west and be near the islands in a 2-4 days. Think this is the wave the models were picking up on (GFS and few others)

Quick and easy, Harvey is looking more and more subtropical to me, I know that occasionally storms go from sub tropical to tropical. what happens if the storm takes on a sub tropical appearance, would the decide to start calling it Sub tropical storm Harvey? I'm just curious if something like that is possible.

Harvey a bit stronger than they thought
THE FIRST REPORTS FROM AN AIR FORCE RESERVE UNIT RECONNAISSANCE
AIRCRAFT INVESTIGATING TROPICAL STORM HARVEY INDICATE THAT HARVEY
IS STRONGER THAN PREVIOUSLY ESTIMATED. THE AIRCRAFT FOUND A
MINIMUM SEA-LEVEL PRESSURE OF 999 MB AND PEAK FLIGHT-LEVEL WINDS OF
62 KT. BASED ON THESE DATA...THE INTENSITY OF HARVEY IS NOW
ESTIMATED TO BE NEAR 60 MPH.

I am familiar with a lot of the lingo, but this kinda through me for a loop:
"A QUIKSCAT PASS AT 1036Z INDICATED A LARGE AREA
OF UNFLAGGED 30 KT WINDS..."
Is that for the disturbance by the Cape Verde Islands?
No -- that was from an earlier discussion on Harvey. --Clark

Don't have much time to add anything -- been out of town and am now fighting off food poisoning -- but will add this little bit...
* Harvey is dubiously a tropical cyclone, but is trying to become more and more tropical through time...sort of what the has been saying all along. The intensity is somewhat of a surprise, but it is likely a storm like Franklin -- a shallower storm with the strongest winds at flight level also reaching down to the surface. It has a decent window for some strengthening as it accelerates out to sea, like Franklin did, but should ultimately meet cooler waters. It's probably here for a few days, though.
* There's no 95L on it yet, but at this rate, we will have storm #9 within the next day or two. Already with a pressure of 1008mb and convection all around the center, the area of low pressure S & SW of the Cape Verdes continues to become better organized. Look for 95L to be designated later today -- if it doesn't go to TD 9 -- with strengthening likely thereafter. The system should continue west for a few days; beyond that, its track will be influenced by how strong it becomes and how much of an effect Harvey has on eroding the subtropical ridge as it moves eastward. There's a good bit of model support for this one.
* Bill Gray is calling for 20 named storms now, in line with NOAA's forecast of 18-21. I don't see much of a reason to disagree with that if the activity of the past two seasons continues. The conditions are certainly ripe for something, and HF's call of thnigs breaking loose soon meets with agreement here.
* Not going to discuss the Kerry Emanuel article in Nature about storm intensity and global warming other than to say that there are limitations within the study that need to be corrected for and that, once again, Chris Landsea's comments are the ones best suited for the task.
More if I feel better in the next day or two...

I like storms like Harvey.
Smiall, fairly insignificant and most importantly Moving NorthEastward in the Open Atlantic.
Welcome to August.

What do u think of that It looks like it should be a invest by now I think Maybe even a TD but I'm not the best at this can some one give me a indepth anynalist on this sorry if I spelled stuff wrong.

Read this "NONAME":EASTERN ATLANTIC TROPICAL WAVE NOW ALONG 29W/30W SOUTH OF 17N
MOVING WEST 10 KT. A 1008 MB LOW PRESSURE CENTER IS ALONG THE
WAVE NEAR 11N. THIS LOW CENTER IS FORECAST BY THE MODEL TO
CONTINUE ITS WESTWARD MOVEMENT FOR AT LEAST THE NEXT 96 HOURS
ALONG MORE OR LESS THE SAME LATITUDE. NUMEROUS STRONG SHOWERS
AND THUNDERSTORMS FROM 11N TO 13N BETWEEN 27W AND 28.5W...AND
IN CLUSTERS FROM 8N TO 13N BETWEEN 30W AND 32W.
I think it will be a couple of days before it becomes a depression. If it forms early it could be influenced by an ULL in the middle of the Alantic that would pull it more poleward.

Hi guys,
well just had my first oppurtunity to have a look at Harvey on the visibles, and i nust say i havent seen a system looking like this for quite some time. It looks quite subtropical in nature, as stated yesterday when it was classified. It is giving a real good go at looking like how a tropical cyclone should look though, and if that convective activity over the LLCC continues, it should look a bit better  Not sure what the conditions have been like in Bermuda today, but they have been affected by the large curved band removed from the centre and located in the eastern semi-circle. If Harvey organises enough, i think we will see him make it to minimal hurricane intensity, probably around the same time it passes closest to Bermuda. From then on out it looks likely to carry on across the Atlantic over this weekend.
Just also had a very quick look at the wave / low over the east-central atlantic. I think this has a day or two to go at least, before being classified as anything - not organised enough yet really, but showing the signs!
Kind regards

OK, never mind. I watch the all the time and was afraid they has assigned "NONAME" to this system!
Thankfully Harvey is a fish killer. But I'm afraid the one you're referring to has all the potential to become a very deadly Irene. The stars, wind, SSTs, etc. are all aligning perfectly to start August off badly.

Yeah - that one off Africa looks impressive.
Over Panama to the Yucatan, is that the remnants of 93L flaring up as it moves into the Pacific? Or is it just normal evening thunderstorms?
