EVENT...SHOWERS ALONG THE IMMEDIATE S COASTLINE CAPABLE OF PRODUCING
HVY RAINS
.
SATELLITE ANALYSIS AND TRENDS...ATTM THE BULK OF THE SHOWERS AND HVY
RAIN IS LOCATED JUST OFFSHORE OF VERMILION/IBERIA/ST. MARY/TERREBONNA/
LAFOURCHE/PLAQUEMINES PARISHES..HOWEVER SOME OF THAT HVY RAIN DOES
APPEAR TO BE SLOWLY MOVING OVER ST. MARY PARISH WITHIN THE LAST 30 MINS.
RECENT IR IMAGERY INDICATES THAT SOME CELL MERGING HAS OCCURRED IN THE
LAST HR..WHICH DID LEAD TO A BRIEF OVERSHOOTING TOP S OF ST. MARY PARISH.
COLDEST CLOUD TOP TEMPS ARE CURRENTLY AT -62C AND AUTOMATED STLT ESTIMATES
ARE INDICATING RAINFALL RATES OF 0.9-1.2"/HR WERE LIKELY OCCURRING
BETWEEN 1030Z AND 1130Z JUST OFFSHORE OF THE PARISHES MENTIONED EARLIER.
.
ANALYSIS OF SFC AND MID-LVL WINDS SHOWS NEARLY CALM CONDITIONS ACROSS
MOST OF S LA AT THE SFC AND MID-LVL FLOW IS GENERALLY WSW TO ENE.
THIS SEEMS TO SUGGEST THAT SHOWERS WILL BE SLOW MOVING WITH WEAK SFC
FLOW BUT SHOULD DRIFT TO THE ENE.  SHOWERS AND HVY RAIN ARE EXPECTED TO
CONTINUE ACROSS S LA FOR THE NEXT FEW HRS..WITH GREATEST THREAT OF HVY
RAINFALL ALONG THE IMMEDIATE COASTAL AREAS.
