Wait for first visible tomorrow morning then decide. It appears to me that Biloxi is on the edge of the 70% cone from NHC.

This from the wear 3 website

BREAKING NEWS: Escambia County, Florida - Escambia County, Florida public schools (pre-K - 12th grade) will be closed Monday and Tuesday due to the approach of hurricane Ida. Escambia County, FL declared a state of emergency Sunday evening. They are asking for voluntary evacuations along coastal areas. Bridges will be shut down if winds sustain 45 mph or more.

IMHO, anyone in the Watch Area is not out of danger at this time. How many times have we seen changes in a normal season. It's November 8th, and in many aspects we are in a bit of uncharted territory. Guidance has not been real good beyond 6-12 hours.

If it's TROPICAL, the highest winds will be on the NE or right front quadrant. Remember, even with a tight pressure gradient on the west of a northward moving storm, the left front quadrant or NW quadrant in this case has the forward speed of the storm subtracted from the average winds. The right front quadrant adds the forward speed.

is there a thread where we can guess where the storm is going to landfall? I am guessing panama city or just west of there.

looks like clouds are slightly warming outside of the eyewall. But, it appears the eyewall and around there is starting to show some new colder clouds building. IF** that continues I expect we are going to do the same thing that we did when this last burst started 4 hours ago.

Thanks for the information and please forgive me for asking, "Biloxi is on the edge of the 70% cone from the NHC". What exactly do you mean? That there's a 70% chance of Ida making landfall near Biloxi?

Ivan, have you noticed that on the latest IR pics that the core/eye wall/ is starting to show some new colder clouds going up?

Cloudtops warming, cloudtops cooling, what does that mean? If the cloudtops are warming does that mean a stronger or a weaker system?

Is the whole cloud field starting to get elongated?

warming = decrease
cooling = increase

Generally warming cloudtops indicate weakening, and colder ones indicate strengthening.

Lynn


Lyn, As the plane flies through a storm, the SFMR detects microwave radiation naturally emitted from foam created on the sea by winds at the surface. Computers then determine wind speeds based on the levels of microwave radiation detected. I think early on when it was first deployed it was not right on the money and with time it has been tweaked to give a pretty accurate wind reading. In 2005 only the NOAA P3s had the SFMR, now the Air Force WC-130s have them too.


Hi JTE! I'm glad you added that. It follows the direction and speed of sea spray and foam blown by the surface winds to come up with near-surface winds. It is a truly great instrument/invention, even with its limitations.

Glad someone asked! I looked in the acronym definitions but it didn't give too much detail. Another question I have is about the dropsonde that is in the pic on the link you posted pojo. Are they tethered and get pulled back in to "read" or gone forever and read remotely? Just wondering if there are millions down there somewhere at the bottom of the sea waiting to be discovered by Jacques Cousteau and the Calypso.

slightly and it usually gives a hint of direction for a while.

Didn't see that yet...scrolling across the bottom on Channel 3 during programming. State of Emergency declared (don't know if that's right now or in the morning).


It's a protocol and Standard Operating Procedure thing. SOE is probably activated now in that part of FL. SOE's have to be initialized before any closings of schools, city, county, government offices can be closed. That way everyone is on the same page.

The lower the clouds the warmer they are the weaker the thunderstorms the weaker the system could be. The Higher the clouds the colder they are the more intense the thunderstorms the stronger the storm.
