SATELLITE ANALYSIS AND TRENDS...COLDEST CLOUD TOPS PER IR IMAGERY HAVE
MOVED OFFSHORE BUT SOME HEAVIER RAINS STILL REMAIN AT THIS TIME IN
LAFOURCHE AND PLAQUEMINES PARISHES. VIS IMAGERY SHOWS A SUBTLE BNDRY
MOVING ONSHORE IN S/CENTRAL LA THAT CELLS HAVE STARTED TO FORM NEAR AT
THE SW EDGE OF THE MCS. OBJECTIVE ANALYSIS REVEALS A POCKET OF MOD STRONG
MOISTURE CONV OVER THIS AREA INDICATING THAT THE MCS COULD CONTINUE ITS
BACKBUILDING INTO ST. MARTIN/IBERIA PARISHES. LOCAL PW MAX IS SHOWN IN
THIS AREA BY GOES SOUNDER/GPS VALUES TO BE 1.75-1.85" WITH S/SWRLY SFC
WINDS S OF THIS BNDRY PROVIDING MOIST INFLOW FROM THE GULF. ESTIMATE THAT
THE PARISHES OF PLAQUEMINES/JEFFERSON/LAFOURCHE HAVE HAD ANYWHERE FROM 3"
TO LOCALIZED 5" IN THE LAST SEVERAL HRS SO ADDITIONAL RAINFALL WILL ONLY
ADD TO ANY ALREADY OCCURRING FF. WITH A SMALL LINE OF OVERSHOOTING TOPS
SEEN ON VIS IMAGERY ALONG THE BNDRY EXTENDING FROM SW ST JAMES PARISH TO
CENTRAL PLAQUEMINES PARISH AND THE POSSIBILITY OF BACKBUILDING/DEVELOPMENT
OF CELLS..SE LA COULD SEE ANOTHER 1-2". DO NOT BELIEVE THAT RAINFALL
RATES WILL BE NEARLY AS HIGH AS WITH THE CELLS NOW OFF THE LA COAST AS
DRY SLOT IS NOW OVER WRN LA AND WINDS ARE NOT AS FAVORABLE.
