WX update

…Fred becomes a hurricane…the second of the Atlantic season…

At 1100 PM EST, the center of Hurricane Fred was about 445 miles west-southwest of the southernmost Cape Verde Islands.
Fred is moving toward the west-northwest near 12 mph, and a turn toward the northwest is expected over the next day or so. Fred is then forecast to turn toward the north-northwest with a decrease in forward speed on Thursday.
Satellite images indicate that maximum sustained winds have increased to near 75 mph with higher gusts. Fred is now a category one hurricane on the Saffir-Simpson hurricane scale. Additional strengthening is forecast during the next day or so, followed by slow weakening beginning on Thursday.
Hurricane force winds extend outward up to 25 miles, and tropical storm force winds extend outward up to 85 miles.

The Latest Discussion on Hurricane Fred from the National Hurricane Center
The latest few infrared images from Meteosat-9 indicate that Fred has developed an eye…following the trend observed in 1934 UTC windsat data and 2112 UTC ssm/is data from earlier this evening. The eye is surrounded by deep convection with very cold cloud tops to -80 c…and the central dense overcast is expanding and becoming more axisymmetric. Two recent AMSU overpasses yielded intensity estimates of 68 kt and 70 kt from UW-CIMSS…and Fred is being upgraded to a 65-kt hurricane in this advisory.
Fred has begun to slow down and turn toward the west-northwest with an estimated initial motion of 295/10. The narrow ridge that has been north of the hurricane is now breaking down due to two shortwave mid- to upper-level troughs located near 27n 37w and near the Canary Islands. As a result…Fred will continue to turn toward the northwest then north over the next 48-72 hours. The model envelope remains tightly-clustered…and the new official forecast did not have to be adjusted from the previous forecast by much. Interestingly…the GFDL and HWRF have both consistently been on the western edge of the model envelope…and they have done a better job than the other models by not pulling Fred northward too soon. This could be an indication that Fred might not turn as sharply to the north as indicated in the official forecast…and future forecasts may require some shifting to the west.
Fred appears to have a clear path for continued strengthening for the next 24 hours or so due to sufficiently warm SSTs and low shear. However…none of the guidance shows fast strengthening… and the SHIPS rapid intensification index is only 21 percent at the moment. Therefore…the official forecast continues to peak Fred at 80 kt in 24 hours…followed by gradual weakening beginning at 36 hours once southwesterly shear begins to increase. SSTs only decrease gradually north of Fred…and it appears that the shear and a drier mid-level environment will play the biggest role in modulating the intensity beyond 72 hours.

E-mail notification messages are sent when:

  1. An Atlantic Tropical Depression forms (i.e., Tropical Prediction Center begins issuing advisories).
  2. An Atlantic Tropical Depression is upgraded to a Tropical (named) Storm.
  3. An Atlantic Tropical Storm is upgraded to a Hurricane.
  4. There is a significant change in the intensity of an Atlantic Hurricane.
  5. Watches or Warnings (Hurricane/Typhoon or Tropical Storm) are issued for the United States or its Territories (both Atlantic and Pacific storms). During watch and warning situations, an update message will be provided every 6 to 12 hours, or as appropriate.

[COLOR=blue]Oops, I posted this in the wrong place folks,… [/COLOR]I just found the “Marine weather” thread under Maritime Topics.

Thats okay NC., make all the mistakes you want to here…We all require your perfection, while you are on the job…:slight_smile:

[B]Hey, thats a contradiction :confused: lol [/B]
[B]I’m not trying to take “Freds” job, just was forwarding something I got while @ work. I need to leave weather stuff to Fredwx. [/B]

[B]If I don’t get any better at this, I might start a new thread (on purpose) and I will call it…Recipes. :smiley: [/B]

count me in for the recipes, I’m an ex chef and have a great recipe for hardtack and biscuits and another for bird shit soup

Sorry NC, I didn’t realize you were at work…When you coordinate the movements of the ships of the world, you make it look so easy, I just assumed you were goofing off at home…:smiley:

:cool: [B]nah no goofing off @ work, I think I will start the recipe thread just to piss mr 100 ton off…lol he is making fun of me. I have feelings you know :smiley: [/B]

I have feelings toooo, were is the love??? going to call doctor phil after this, :eek::eek::eek:

[B]oh, and I want my ring back. lol [/B]

Great, now we will need 2 new threads, recipes and therapy…:wink:

i’m crying now doctor phil help
