This is from a local met.: Brief Update Tropical Discussion On Rita Palm Beach County Central/South Florida 800pm EDT Monday September 19 2005 A brief look I had this morning on the upper winds at 200mb showed a Southeast flow along the Southeast and east coast of Florida from the upper air data analyzed using the digiatmosphere program...just briefly the crictical point is whether a jog to the Northwest for a small time period tonite and early morning. Rita has been moving based on latest satellite loops WNW a jog NW for a small time could change things for south florida. We will need to watch for that jog from now thru the 12hr period or so..if this should happen then all of palm beach county could be seeing 40+ winds sustained. I included the 200mb analysis..from the 12z data i used..there appears to be some motion of the convective field band to the NW NW sector of Rita's center.. I will see how the upper winds show up tonite next few hours..the winds at mid levels are from the EAst Northeast...but the surface winds are still Northeast..that could support a wind field for a center readjustment or slight jump NW.. Again just something to keep very very close watch on.. More on that later...official forecast looks okay but I still have still the concern of that track being possibly compromised just a little farther north...it wont be a smooth track but wobbling WNW and NW..and back more WNW to W once it reaches the Gulf then bending NW again..this has been the problematic tracks of katrina and ophelia due to changing directional winds aloft..!!with height..!!. |
