HURRICANE RITA DISCUSSION NUMBER 20
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
11 AM EDT THU SEP 22 2005

RITA APPEARS TO HAVE REACHED ITS PEAK INTENSITY DURING THE PAST
12 HOURS. HURRICANES TYPICALLY DO NOT MAINTAIN SUCH HIGH INTENSITY
FOR A LONG TIME. INITIAL INTENSITY ESTIMATE IS 145 KNOTS. ALTHOUGH
SOME FLUCTUATIONS IN INTENSITY ARE LIKELY DURING THE NEXT DAY OR
TWO...DUE TO EYEWALL REPLACEMENT CYCLES...AN OVERALL GRADUAL
WEAKENING TREND SHOULD TAKE PLACE. THIS WEAKENING TREND IS BASED ON
LOWER OCEANIC HEAT CONTENT ALONG THE FORECAST TRACK AND INCREASING
SHEAR. NEVERTHERELESS...RITA IS EXPECTED TO MAKE LANDFALL AS A
DANGEROUS HURRICANE OF AT LEAST A CATEGORY THREE INTENSITY.

RITA HAS BEEN MOVING TOWARD THE WEST-NORTHWEST OR 295 DEGREES AT 8
KNOTS. A STRONG HIGH PRESSURE SYSTEM CURRENTLY CENTERED OVER
NORTHERN TEXAS/OKLAHOMA IS EXPECTED TO SHIFT EASTWARD ALLOWING RITA
TO TAKE A MORE NORTHWESTERLY AND NORTHERLY TRACK. THE EASTWARD
SHIFT OF THE HIGH IS FORECAST BY ALL GLOBAL MODELS...RESULTING IN
TRACK GUIDANCE CONSISTENTLY TURNING THE HURRICANE TOWARD THE
NORTHWEST AND NORTH TOWARD THE UPPER-TEXAS OR THE WESTERN LOUISIANA
COASTS. AFTER LANDFALL...STEERING CURRENTS ARE EXPECTED TO WEAKEN
AND THE CYCLONE COULD MEANDER FOR A COUPLE OF DAYS IN THE VICINITY
OF NORTHEASTERN TEXAS...PRODUCING HEAVY RAINS.

BASED ON THE FORECAST TRACK AND WIND RADII...HURRICANE WARNINGS HAVE
BEEN ISSUED AT THIS TIME FROM PORT O'CONNOR TEXAS TO MORGAN CITY
LOUISIANA. TROPICAL STORM WARNINGS ARE IN EFFECT ON EITHER SIDE OF
THE HURRICANE WARNING.

[RONSTOO]

1. I think its going to turn north

NOLA is gonna catch the right or "dirty side" of Rita. The high ridge over Texas is expected to weaken in nexr 24 hours which will bring it north.

[Penndems]

2. Hard to tell at this point

All the models seemed to be lined up for this thing to make landfall between Galveston and Freeport. Houston is right in line to take a major hit, it would seem. :( :scared:

[mtnester]

3. Pray...if this thing takes any unusual curve, there is not enough time to

get people out of fringe areas that are not evacuated. Think Mobile and east.

For that matter, the dang thing could do a complete right turn and head for Tampa.

No one that lives on the shore of the Gulf in the next 3 days is safe, IMO.

On Edit - I lived in the Panhandle for Elena...first to Tampa, then back out and just kissed Ft Walton Beach...then back to Tampa, then finally all the way in at Ft Walton Beach...shows really how they can baffle even the pros

[Penndems]

4. There's always that possibly, but all the collected information

thus far seems to show that she's headed for the Texas Gulf Coast, with hurricane force winds spreading into western Louisiana. Anyone who has left already should be evacuating before early tomorrow morning. Folks in east Texas should be going west or northwest. Those in western Louisiana should be going north and east.

I'm praying for everyone, but especially for these folks.
