OFFICIAL IRENE FORECAST – CONE OF UNCERTAINTY – FRIDAY 8 PM EDT

TWO LEFT CLICKS FOR TOTAL ENLARGEMENT

This is self-explanatory.  If you are anywhere within the cone of uncertainty please do not be careless in your thinking.  Stay alert, keep a clear head, and do not allow that epidemic disease, terminal uniqueness, to cause you to think that “it” always happens to the other guy (or gal).  Do not take any unnecessary chances.  Be patient, use common sense, and remember that this too shall pass.

My thoughts are with you.

Forecast for Irene by the European Model – posted 8-24-2011

This posting is time-sensitive and is now out of date.  For step by step instructions on access to an animated loop of the most current ECMWF (“European”) model go to the following link:  https://cloudman23.wordpress.com/2011/08/25/ecmwf-model-run-the-european-model/

Hurricane Irene is now a category 3 storm.

IF YOU ARE WITHIN THE PUBLISHED CONE OF UNCERTAINTY IT WOULD BE FOOLISH TO IGNORE THIS STORM EVEN THOUGH YOU MIGHT NOT BE CLOSE TO WHERE IT IS CURRENTLY PREDICTED TO GO.  That is not just my opinion but also the opinion of National Weather Service forecasters.

TO FIND THE MOST RECENT CONE OF UNCERTAINTY DEPICTION, GO TO THE RIGHT-HAND MARGIN OF THIS PAGE AND UNDER “TROPICAL WEATHER” CLICK ON “NATIONAL HURRICANE CENTER HOME.

The graphic that follows is a 72 hour (3 day) forecast position that originated at 0000 Greenwich Time on the 24th (which is 2000 hours on the 23rd EDT time – or 8 pm).   The path that this European Model predicts correspond closely with today’s official forecast track of the National Weather Service.

On this graphic, and most on this site, two independent left clicks will enlarge to the fullest.  The poorness of the resolution is due to considerable enlargement from the original.

Early U.S. Landfall forecast for Irene by the European Model – 8-23-2011

Mind you, I am not formally trained in forecasting.  I am conveying to you what I am deriving from others and when I include my personal opinion I try to make that clear.  Also, very small changes in course can make a huge change in the location of a storm’s landfall, particularly when it is so far out as is Irene this moment.  For example, I am in West-Central Florida, 17 miles inland from the Gulf of Mexico but none-the-less, you can bet your sweet bippie that I’m on the alert.  SO IF YOU ARE WITHIN THE PUBLISHED CONE OF UNCERTAINTY IT WOULD BE FOOLISH TO IGNORE THIS STORM EVEN THOUGH YOU MIGHT NOT BE CLOSE TO WHERE IT IS CURRENTLY PREDICTED TO GO.  That is not just my opinion but also the opinion of National Weather Service forecasters.

Over the last two years the European Model has done the best at predicting the paths of tropical systems under these particular circumstances.  The graphic that follows is a 5 day forecast position that originated at 0000 Greenwich Time on the 23rd (which is 2000 hours on the 22nd EDT time – or 8 pm).  A lot can happen in 5 days so take this for what it’s worth.  This does correspond closely with determinations made by the National Weather Service today.

I will check the next run (they occur at 0000 and 1200 or twice a day – Greenwich Time) and if there is a significant change I will post it.

Irene Is Now a Hurricane – 8-22-2011

PLEASE NOTE – THIS IS A TIME-SENSITIVE POSTING

Below is the 11 am (Eastern Daylight Time) cone of uncertainty for hurricane Irene from the National Hurricane Center.  Remember, only minor shifts toward the west or east can change the complexion of things drastically.  Such changes are common – in fact, some meteorologists refer to resultant realignments of the spreading cone as “windshield wipering.”  Left click the image twice for full enlargement.
