TIDES ARE EXPECTED TO INCREASE TO ABNORMALLY HIGH LEVELS AND
PERSIST AT HIGHER LEVELS THROUGH THE WEEKEND AND INTO EARLY NEXT
WEEK. ASTRONOMICAL TIDES ARE IN THE ANNUAL HIGH SPRING TIDE CYCLE
WHICH HAVE LARGER RANGES THAN NORMAL. THE AUGMENTATION OF WAVE
ACTION AND STRONG EASTERLY WIND GRADIENT WILL DEVELOP A PROLONGED
PERIOD OF ABNORMALLY HIGH TIDES THAT WOULD BE PARTICULARLY
REALIZED DURING DAILY HIGH TIDES BUT COULD CONTINUE THROUGH THE
LOW TIDE PORTIONS OF THE CYCLE THIS WEEKEND.

INTERESTS ALONG THE COAST AND ON THE TIDAL LAKES OUTSIDE THE
HURRICANE LEVEE PROTECTION SYSTEMS SHOULD CLOSELY MONITOR THE
SITUATION. ALSO INTERESTS ALONG LOWER REACHES OF RIVERS AND
STREAMS THAT DRAIN INTO THE TIDAL LAKES SHOULD BE MINDFUL OF
RISING WATER LEVELS DUE TO TIDAL AFFECTS. BE PREPARED TO TAKE
ACTIONS TO PROTECT LIFE AND PROPERTY IF COASTAL FLOOD WATCHES OR
WARNINGS ARE ISSUED IN THE UPCOMING DAYS. ACCESS ROADS INTO TIDAL
MARSHES...MARINAS AND AREA CAMPS MAY BECOME INUNDATED AND
IMPASSIBLE FOR LENGTHY PERIODS THIS WEEKEND.

STAY TUNED TO LOCAL TV...RADIO...NOAA ALL-HAZARDS RADIO OR THE
INTERNET FOR THE LATEST ON THIS POTENTIAL COASTAL FLOODING
EPISODE. WHILE CONFIDENCE IS RATHER HIGH THAT ABNORMALLY HIGH
TIDES WILL OCCUR...THERE REMAINS SOME UNCERTAINTY ON THE DEGREE
OF INUNDATION. THOSE COASTAL SECTIONS THAT FACE EAST...GENERALLY
FROM BAY ST LOUIS MISSISSIPPI TO PORT FOURCHON APPEAR MOST
VULNERABLE...THOUGH HIGHER TIDES CAN AND WILL LIKELY OCCUR ALONG
THE ENTIRE NORTH CENTRAL GULF COAST THIS WEEKEND. A COASTAL FLOOD
WATCH MAY BE POSTED LATER TODAY FOR PORTIONS OR ALL OF THE SHORES
ALONG MISSISSIPPI AND SOUTHEAST LOUISIANA.
