.
SATELLITE ANALYSIS AND TRENDS...IR IMAGERY SINCE COMING OUT OF
ECLIPSE PERIOD HAS SHOWED CONVECTION SLOWLY BUT STEADILY MOVING
TOWARDS THE COAST OF FLORIDA.  LATEST IMAGERY SHOWING THE BULK OF IT
JUST OFFSHORE OF ST. JOHNS COUNTY.  MANUAL/AUTOMATED ESTIMATES GIVING
GENERAL               .75"-1.0"/HR FROM 0845Z THROUGH 0945Z WITH COLD
TOP DEVELOPMENT OVER SE DUVAL/ST JOHN'S COUNTY..SOME AREAS MAY HAVE SEEN
ALMOST ALL OF THAT RAIN IN JUST THE LAST 30 MIN..BUT OFFSHORE SEEING
HIGHER ESTIMATED HOURLY TOTALS OF 1.25"-1.5"/HR.  THINKING THESE HAVIER
RATES WILL MAKE IT ONSHORE OVER NRN ST. JOHNS/SE DUVAL COUNTIES SHORTLY.
AM SEEING SOME CYCLONIC CURVATURE IN THE LOW LEVELS IN IR IMAGERY
SUGGESTING A THE DEVELOPMENT/PRESENCE OF A MCV WHICH COULD GIVE SOME
LOCALIZED AREAS 2.0"/HR RAIN RATES GIVEN PW VALUES AND 1.8" PW VALUES
IN THE REGION ALONG WITH RUC 10Z MODEL SOUNDINGS.
