Within 10 minutes local news showed storm surge of 5 ft...then in full forecast says 5-7 ft...
I know there is nothing we can do about it regardless, but it would be nice to have the accurate info for those of us in low lying areas.
Can anyone answer my question from earlier about is high tide added on top of storm surge amount or is it already factored in? Storm surge= 5 ft total or 5 ft Storm Surge plus an additional 2-3 ft from high tide= 7-8 ft total?

from the NHC -
SUBJECT: CHANGES TO STORM SURGE INFORMATION IN TROPICAL
CYCLONE PUBLIC ADVISORIES FROM THE NATIONAL
HURRICANE CENTER: EFFECTIVE MAY 15 2009

REFERENCE: SERVICE CHANGE NOTICE 09-14 ISSUED FEB 24 2009

STARTING IN 2009...IN AN EFFORT TO ENSURE STORM SURGE FORECASTS
ARE FULLY UNDERSTOOD BY THE WIDEST POSSIBLE AUDIENCE...THE
NATIONAL HURRICANE CENTER /NHC/ WILL CHANGE THE WORDING IN THE
PUBLIC ADVISORY TEXT PRODUCTS TO REFERENCE STORM SURGE OR STORM
TIDE IN TERMS OF HEIGHT ABOVE GROUND LEVEL.

STORM SURGE REFERS TO THE ABNORMAL RISE IN SEA LEVEL
ACCOMPANYING A HURRICANE...THE DIFFERENCE BETWEEN THE OBSERVED
LEVEL OF THE SEA SURFACE AND THE LEVEL THAT WOULD HAVE OCCURRED
IN THE ABSENCE OF THE CYCLONE.

STORM TIDE IS THE ACTUAL LEVEL OF SEA WATER RESULTING FROM THE
ASTRONOMIC TIDE COMBINED WITH THE STORM SURGE. STORM TIDE IS OF
PARTICULAR IMPORTANCE IN THE NORTHERN LATITUDES...WHERE
THERE IS A GREATER DIFFERENCE IN HEIGHTS BETWEEN HIGH AND LOW
TIDE LEVELS...AND WHEN A STORM IS EXPECTED TO LANDFALL NEAR THE
TIMES OF ASTRONOMICAL HIGH TIDE.

BEGINNNING IN 2009...NHC PUBLIC ADVISORY PRODUCTS /TCP/S WILL
PROVIDE THE FOLLOWING POSSIBLE STATEMENTS ON COASTAL FLOODING
ASSOCIATED WITH TROPICAL CYCLONES:

EXAMPLE 1
STORM SURGE WILL RAISE WATER LEVELS BY AS MUCH AS NN /FOR
EXAMPLE 15/ FEET ABOVE GROUND LEVEL ALONG THE COAST...WITH LARGE
AND DANGEROUS BATTERING WAVES...NEAR AND TO THE ZZZZ /DIRECTION
FOR EXAMPLE EAST/ OF WHERE THE CENTER MAKES LANDFALL. THE SURGE
COULD PENETRATE AS FAR INLAND AS ABOUT NN /FOR EXAMPLE 30/ MILES
FROM THE SHORE WITH DEPTH GENERALLY DECREASING AS THE WATER
MOVES INLAND.

EXAMPLE 2
STORM TIDE WILL RAISE WATER LEVELS BY AS MUCH AS NN /FOR EXAMPLE
18/ FEET ABOVE GROUND LEVEL ALONG THE COAST...WITH LARGE AND
DANGEROUS BATTERING WAVES...NEAR AND TO THE ZZZZ /DIRECTION FOR
EXAMPLE EAST/ OF WHERE THE CENTER MAKES LANDFALL. STORM TIDE
COULD PENETRATE AS FAR INLAND AS ABOUT NN /FOR EXAMPLE 30/ MILES
FROM THE SHORE WITH DEPTH GENERALLY DECREASING AS THE WATER
MOVES INLAND.

PLEASE SEE SERVICE CHANGE NOTICE 09-14...ISSUED ON FEB 24
2009...FOR FORMAT CHANGES TO TROPICAL CYCLONE PUBLIC ADVISORY
PRODUCTS FOR THE ATLANTIC...EAST PACIFIC...AND CENTRAL PACIFIC
HURRICANE BASINS: EFFECTIVE MAY 15 2009.

AN EXAMPLE OF THE TCP PRODUCT FOR 2009 IS PROVIDED ONLINE AT

Upper winds not bad up there right now. 21kts.

[bayoubebe]

Wow, I'm sorta shocked. Just got a recorded message saying our schools will be CLOSED tomorrow.
We are about 12 miles NW. of Nola.

[IvanSurvivor]

Thanks to all that answered my post...looks like we might take a little water again. All puckered up and soon to be hunkered down...

Descending to operational altitude

[smw1981]

Below is a chart of when the high tides will be during landfall somewhere in the gulf coast.

Ivan...Finally found it after looking at 20 pages lol...I hope this answers your question..

[IvanSurvivor]

ETA on Obs?

[smw1981]

Ivan Survivor, Of course..by the time I found it, your question had been answered by many! Sorry it took so long!

[bayoubebe]

Thanks to all that answered my post...looks like we might take a little water again. All puckered up and soon to be hunkered down...

I hope you all are safe without damage and I hope the Portofino survives
One of our favorite places to stay.

[Dave]

[PTPatrick]

seems like on latest image that due north better commence soon if the storm is make its next point, otherwise might miss it a hair west...which will be a first for today

Check your PM's just sent you instructions...Dave

[Dave]

[Javlin]

seems like on latest image that due north better commence soon if the storm is make its next point, otherwise might miss it a hair west...which will be a first for today

Latest sat is showing a stretch of N-S in cloud structure will probably happen soon.Kevin
she is book'in it might miss'it by some 12-18(W) miles before the change.
