MARINE
AS OF 255 PM EDT WEDNESDAY...
KEY MESSAGES:
- SCAS IN EFFECT FOR ALL COASTAL WATERS DUE TO ELEVATED NE WINDS
AND SEAS OF 5-10FT. GALE WARNINGS HAVE BEEN CANCELLED.
- GRADUALLY IMPROVING CONDITIONS THROUGH THE EARLY WEEKEND, THEN
PLEASANT CONDITIONS EXPECTED INTO EARLY NEXT WEEK.
AFTERNOON SFC ANALYSIS AND SATELLITE IMAGERY SHOW TROPICAL SYSTEM
IMELDA WELL OFFSHORE TO THE SE AND STRONG HIGH PRESSURE BUILDING IN
FROM THE N. NE WINDS ARE ELEVATED DUE TO THE PRESSURE GRADIENT
BETWEEN THESE FEATURES AS WELL AS CAA OVER THE WARM WATERS. LATEST
OBS INDICATE WINDS OVER COASTAL WATERS AND THE MOUTH OF THE BAY ARE
AT ~25KT WITH GUSTS TO 30KT. SINCE OBS HAVE BEEN UNDER GALE WARNING
THRESHOLDS FOR A FEW HOURS, ALL GALE WARNINGS HAVE BEEN CANCELLED
AND REPLACED WITH SMALL CRAFT ADVISORIES. OVER THE BAY, CURRITUCK
SOUND, AND RIVERS, WINDS ARE ~20KT WITH GUSTS TO 25KT. SCAS ARE
STILL IN EFFECT FOR THESE WATERS. SEAS ARE 10-12FT BASED ON LATEST
BUOY OBS, WAVES 2-4FT.
REMAINING BREEZY OVERNIGHT AND INTO TOMORROW, THOUGH NOT AS WINDY AS
TODAY. EXPECTING THE NE WINDS TO BE DOWN TO 15-20KT IN THE BAY AND
20-23KT OVER THE COASTAL WATERS BY THURS MORNING. WINDS ARE QUICKER
TO DIMINISH THURSDAY NIGHT INTO FRIDAY AS THAT HIGH PRESSURE REALLY
SETTLES IN. WINDS SHOULD BE DOWN TO 10-15KT BY LATE THURS NIGHT,
THEN 5-10KT BY FRIDAY EVENING. SEAS WILL BE SLOWER TO DIMINISH DUE
TO THE PERSISTENT ONSHORE FLOW AND LINGERING SWELL FROM THE
OFFSHORE TROPICAL SYSTEMS. EXPECTING SEAS UPWARDS OF 9FT IN THE
COASTAL ZONES THURS EVENING AND 5-7FT FRIDAY MORNING. WILL
LIKELY SEE 5FT+ SEAS FOR A GOOD CHUNK OF THE WEEKEND. FOR THIS
REASON, DID GO AHEAD AND SET THE END TIME OF THE COASTAL WATER
SCAS TO SATURDAY MORNING WITH EXTENSIONS POSSIBLE. MUCH MORE
PLEASANT CONDITIONS EXPECTED LATE IN THE WEEKEND AND EARLY NEXT
WEEK WITH HIGH PRESSURE REMAINING IN CONTROL.
TIDES/COASTAL FLOODING
AS OF 300 PM EDT WEDNESDAY...
TIDAL ANOMALIES ARE STEADILY ON THE RISE AS EXPECTED, ALREADY
ON THE ORDER OF 1-1.5 ABOVE NORMAL THIS MORNING, WITH ADDITIONAL
ANOTHER 0.5 TO FT OF SURGE EXPECTED WITH THE TIDE CYCLE THIS
AFTERNOON AND EVENING, HIGHEST ACROSS THE LOWER BAY DUE TO THE
COMBINATION OF STRONG NE WINDS AND WAVE ACTION/INCREASING SEAS
(DUE TO BOTH WIND WAVES AND SWELL).
TIDAL GUIDANCE CONTINUES TO SHOW A HIGH LIKELIHOOD OF AT LEAST
MINOR COASTAL FLOODING DURING HIGH TIDE CYCLES TONIGHT AND INTO
THURSDAY FOR MANY OF OUR TIDAL SITES, WITH THE HIGHEST WATER
LEVELS OCCURRING DURING THE LATE AFTN/EVENING HIGH TIDE CYCLE
THIS EVENING OVER THE LOWER BAY/TIDAL JAMES. ONLY MINOR CHANGES
IN THE TIDE FORECAST FROM YESTERDAY EVENING'S FORECAST PACKAGE.
ANOTHER 2-3 CYCLES OF MAINLY MINOR FLOODING IS THEN EXPECTED
ACROSS MOST AREAS FROM LATE TONIGHT/EARLY THU INTO THURSDAY
AFTERNOON. BISHOP'S HEAD MAY APPROACH MODERATE COASTAL FLOOD
THRESHOLD ON THU, AS WINDS DIMINISH AND WATER POTENTIALLY GETS
STUCK IN THE CHES BAY.
AT SEWELLS POINT, THE 50TH PERCENTILE VALUE PER ETSS FOR THE WED
EVENING TIDE (5.1 FT MLLW) IS JUST ABOVE 5 FT, WITH THE 90TH
PERCENTILE VALUE (5.4 FT MLLW) JUST BELOW THE MODERATE FLOOD
THRESHOLD OF 5.5 FT MLLW. AT JAMESTOWN, 50TH PERCENTILE
WEDNESDAY NIGHT ON ETSS (4.6 FT), IS JUST ABOVE THE MODERATE
FLOOD THRESHOLD OF 4.5 FT MLLW, WITH THE 90TH PERCENTILE (4.9 FT
MLLW) JUST BELOW THE MAJOR FLOOD THRESHOLD OF 5.0 FT.
WITH THAT IN MIND, REGARDING HEADLINES...MAINTAINING A COASTAL
FLOOD WARNING OVER THE UPPER TIDAL JAMES, GIVEN THE CURRENT
TRENDS AND LATEST ETSS GUIDANCE. ALSO MAINTAINING A COASTAL
FLOOD ADVISORY FOR THE OCEAN CITY AREA, AS WELL AS THE TIDAL
RAPPAHANNOCK AND POTOMAC RIVERS FOR LATE TONIGHT INTO THURSDAY
EVENING. OTHERWISE, COASTAL FLOOD ADVISORIES WERE EXTENDED OUT
ALONG SOUTHSIDE HAMPTON ROADS AND THE TIDAL YORK RIVER IN THE
WEST POINT AREA.
FINALLY, WHILE THE NE WINDS WILL KEEP TIDE LEVELS JUST BELOW
MINOR THRESHOLDS FOR PORTIONS OF THE BAY SIDE OF THE MD EASTERN
SHORE THROUGH THURSDAY NIGHT, BISHOP'S HEAD AND CRISFIELD WILL
APPROACH OR PERHAPS EXCEED MINOR COASTAL FLOOD THRESHOLD. DID
EXPAND THE COASTAL FLOOD STATEMENT TO INCLUDE WICOMICO AND
SOMERSET GIVEN THAT CRISFIELD IS NOW EXPECTED TO REACH MINOR
FLOOD.
