Re: Category 5 Hurricane Katrina Moving Westward in the Gulf

Repost here also for the NW movement guys.

and yet another category five hurricane this season. Data from both
NOAA and Air Force hurricane hunters indicate a significant
pressure drop today and winds have increased to 145 knots. This is
based on a 700 mb wind of 161 knots recently measured by an Air
Force plane and a recalibrated SFMR surface wind of 146 knots.
Satellite intensity estimates were unanimously 140 knots from all
agencies. Because Rita will be crossing an area of high heat
content during the next 12 to 24 hours...it is expected that the
hurricane will maintain its strength. Thereafter...the ocean heat
content is not as high and the intensity changes will be controlled
mainly by eyewall replacement cycles and decreasing heat content.
Some weakening is anticipated but Rita is forecast to make landfall
as a major hurricane...at least category three.
There has been no change in the steering pattern and Rita is moving
westward or 275 degrees at 11 knots. The high pressure system that
has been forcing Rita westward is forecast to weaken and shift
eastward. This will allow the hurricane to turn gradually toward
the west-northwest and northwest during the next day or two. The
core of Rita is basically moving toward the Texas coast and this is
consistent with the track model consensus.

Try and follow a 6 hr track rather then 2 hrs and you get what it has done all day and that is move a whole .01 which is due west since early today 12 hrs ago.

Note from the NHC There has been no change in the steering pattern and Rita is moving
westward or 275 degrees at 11 knots


where did those guys go now anyway? they been posting non stop the last 3 hrs where did they go?
