Area forecast discussion, Jun 21, 8:00 AM EST, 3 hours 30 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSONVILLE FL 900 AM EDT FRI JUN 21 2002 LOW LEVEL COASTAL TROUGH LIES RIGHT ALONG THE IMMEDIATE COAST THIS MORNING WITH A MESO LOW SPINNING WEST ACROSS FLAGLER AND PUTNAM COUNTIES. THE MESO-LOW IS SERVING TO FOCUS THE GREATEST SURFACE CONVERGENCE AND THE THE MAIN RAINFALL BANDS OVER ST JOHNS...CLAY... DUVAL...NASSAU AND CAMDEN COUNTIES. I EXPECT HEAVY RAINFALL TO CONTINUE BETWEEN THE COAST AND THE ST JOHNS RIVER NORTH OF DOWNTOWN AND ALSO EAST OF I-95 NORTH OF DOWNTOWN. RAINFALL TOTALS IN GENERAL HAVE BEEN REASONABLE BUT A FEW LOCATIONS...LIKE NEAR ST AUGUSTINE... HAVE BEEN DUMPED ON WITH UP TO FOUR INCHES OF RAIN. SINCE THE AREA IS SOMEWHAT SATURATED (HOW LONG HAS IT BEEN SINCE I COULD SAY THAT) AND IT DOESNT LOOK LIKE THE RAINFALL WILL LET UP THIS MORNING HAVE ISSUED AN URBAN AND SMALL STREAM FLOOD ADVISORY FOR DUVAL...NASSAU AND ST JOHNS COUNTIES. I DONT SEE THE NEED FOR A FLOOD WATCH AT THIS TIME AND FEEL MOST PROBLEMS WILL BE IN POOR DRAINAGE LOCATIONS. ALSO THE ADVISORY SERVES TO FURTHER HIGHLIGHT THE POSSIBILITY OF FLOODING AND I LEFT OPEN THE POSSIBILITY OF WARNINGS SHOULD SIGNIFICANT FLOODING OCCUR. WITH THE UPPER LEVEL LOW SPINNING OVER THE FORECAST AREA THE REMAINDER OF THE DAY SHOULD BE NASTY. FOCUS MAY SHIFT FROM THE COAST TO INLAND LOCATIONS THIS AFTERNOON...ESPECIALLY IF THE DRY SLOT ALLOWS SIGNIFICANT DAYTIME HEATING OVER THE SOUTHERN ZONES. STAY TUNED WEATHER FANS. MARINE...ST AUGUSTINE RINNING 17-20 KNOTS THIS AM AND WILL KEEP SMALL CRAFT EXERCISE CAUTION GOING. .JAX... .GA...NONE. .FL...NONE.. SANDRIK
