ATL: SANDY - Remnants - Discussion

[jlauderdal]

The fact that media outlets are running Sandy being downgraded from a Hurricane to a TS as a "breaking news" alert is troubling.

watching the national media cover the storm will be as much of an adventure as the storm itself...clear skies, winds 20-30 with higher gusts this morning, sandy lives in south florida for another day..sofla media did a very good job with sandy, just enough coverage, it was accurate and not overdone, big improvement over previous years

hopefully our neighbors in the northeast listen to local authorities and heed the advice, those residents don't have the experience that gulf coast and SE usa residents do with these systems

The storm is a top of the computer screen headline for both the UK and Australian online papers I've checked.

[xironman]

957, wow, that is a pretty impressive pressure drop

The problem is that the category and grouping fails with a system like this, as far as I'm understanding it [very amateur], and as soon as people hear of the storm dropping in category, they let their guard down (they includes a lot of media) without regard for its actual destructive ability.

Am I wrong in understanding that the fears about this storm have almost nothing to do with its status as a Hurricane/Storm/D, or even a tropical system period?

no structural damage to homes/businesses

Unless trees fall on them.

[x-y-no]

Well that was substantially less time spent as a TS than I anticipated.

I'm really impressed with how big the wind field is already. Buoy 41010 has seen continuous TS force winds for nearly a day and a half and looks likely to see them for an additional full day.

I. Maximum Flight Level Temp & Pressure Altitude Outside Eye: 14°C (57°F) at a pressure alt. of 1,523m (4,997ft)
J. Maximum Flight Level Temp & Pressure Altitude Inside Eye: 23°C (73°F) at a pressure alt. of 1,523m (4,997ft)

Is this temp difference "normal"?

For a tropical cyclone? Yes. Its very normal.

Looking east from Juno Beach earlier this morning. Those lower level clouds are moving quite fast. It no longer feels at all tropical here like it normally does when a hurricane/TS is nearby. It's actually a bit chilly. Those low clouds were moving very fast but have now disappeared. I understand that there is some coastal flooding going on with the morning high tide.

[stephen23]

Wow. Pretty impressive how fast sandy has gained strength over past 5 hours.Seems to be on pace to hit euro pressure and wind speeds correct?

[MBryant]

OK! Just for us novices.

(High pressure - Low Pressures) / Distance = wind speed for the most part.

So high ridging from the cold front combined with low trough from the cyclone, tropical or not, across a relatively short distance (close isobars) creates high winds.

Now moisture from the tropics meeting cold air from the front creates excessive precipitation. If this is behind the cold front and has freezing air temperatures at all levels, it can create very heavy snowfall. ( I think I remember a conversion rate of 11" snow to 1" rain, though I suspect less for heavy snow)

Then at coastal areas, storm surge, can create excessive tides as water is pushed onshore and combined with already high astronomical and lunar tide cycles. This could breach and/or overtop barriers to coastal water intrusion. (ie subways, streams and rivers flood)

Do I have this right?

[Jevo]

Erosion Anyone.....?

This is the Boca Raton, FL Surf Cam...... Water is up to the sea wall still in Southern Palm Beach County

[CrazyC83]

Is this deepening part of the baroclinic process or due to hitting a warm spot?

[CrazyC83]

What I would like to know is will we be getting tropical storm winds where I am in central Connecticut. I think the reason a lot of people are shrugging at this (I'm not one of them) is we went through Irene and last years halloween nor'easter with little damage. I have prepared and got everything I need from flashlights, water to more gas for the outside grill just in case we loose power again. but I can't help thinking most people here have never been in a situation in fact a lot of my friends from around here are using the phrase bring it on.... Were not florida or the gulf we don't see these very oftern and usually they are pretty weak by the time they get here so people are just expecting heavy rain and for it to be a bit windier than usual, the only ones who I can see who have any concern are the ones who live on the immediate coast and can see the ocean from their windows....

You can definitely expect winds as strong or stronger than Irene there, for a longer duration, no matter where the landfall location is.

no structural damage to homes/businesses

Unless trees fall on them.

There could be some taller buildings in the bigger cities with window losses that could damage buildings from water. Winds will increase with height!

[CrazyC83]

If winds at the surface are gusting to, say, 70 mph, that would be quite a bit higher at the 10th floor level?

Of course, trees can fall on houses/buildings, and wind-blown debris can break glass. But the wind, itself, without any projectiles, won't be strong enough to cause structural damage in the 40-60 mph range.

If this verifies...

I'm speechless....
(Maybe THAT's why it's so quiet around here, everyone is dumbstruck! This is pretty hard to believe!)

Where is that making landfall? Tough to tell on my phone

[Sanibel]

I'm looking out the window at the receding outer band covering the entire NE horizon. It's windier today than any of the last three days so this thing is pulling in air.
