COASTAL FLOOD WATCH
Warning Issue Date: 309 PM EST THU DEC 31 2009
...COASTAL FLOOD WATCH NOW IN EFFECT FROM SATURDAY MORNING
THROUGH SUNDAY AFTERNOON...
THE NATIONAL WEATHER SERVICE IN GRAY HAS ISSUED A COASTAL FLOOD
WATCH...WHICH IS IN EFFECT FROM SATURDAY EVENING THROUGH SUNDAY
AFTERNOON. THE COASTAL FLOOD WATCH IS NOW IN EFFECT FROM SATURDAY
MORNING THROUGH SATURDAY AFTERNOON.
THE HIGHEST ASTRONOMICAL TIDES OF THE MONTH WILL COMBINE WITH A
DEVELOPING OCEAN STORM TO PRODUCE COASTAL FLOODING...SPLASH-OVER AND
BEACH EROSION NEAR THE TIME OF THE LATE MORNING HIGH TIDE SATURDAY.
THE ASTRONOMICAL HIGH TIDE IN PORTLAND HARBOR WILL BE 11.5 FEET
JUST BEFORE NOONTIME ON SATURDAY. THE OCEAN STORM AND BUILDING
WAVES ARE EXPECTED TO BRING A STORM SURGE BETWEEN 1.0 AND 1.5 FEET
TO THE REGION. THIS WOULD BRING A STORM TIDE BETWEEN 12.5 AND 13.0
FEET TO PORTLAND. STORM TIDES OVER 12.5 FEET IN PORTLAND
CORRESPOND WITH THE ONSET OF COASTAL FLOODING IN THE MIDCOAST
REGION.
ANOTHER HIGH TIDE EARLY SUNDAY AFTERNOON WILL NEED TO BE WATCHED
AS WELL. WINDS MAY BECOME NORTHWESTERLY LATE IN THE WEEKEND WHICH
COULD LESSON THE STORM SURGE. HOWEVER...WAVES WILL BE CONTINUING
TO BUILD AT THE SAME TIME AS THE STORM REACHES ITS CLOSEST
APPROACH TO OUR COASTLINE. VERY LOW PRESSURE WITHIN THIS STORM MAY
BE AN ADDED COMPONENT TO THE STORM SURGE.
THIS COMPLEX SITUATION WILL NEED TO BE MONITORED VERY CLOSELY
THROUGHOUT THE WEEKEND. THE EXACT TRACK AND TIMING OF THE OCEAN
STORM WILL DETERMINE THE EXTENT OF IMPACT FROM THE STORM TIDES.
PRECAUTIONARY/PREPAREDNESS ACTIONS...
A COASTAL FLOOD WATCH MEANS THAT CONDITIONS FAVORABLE FOR
FLOODING ARE EXPECTED TO DEVELOP. COASTAL RESIDENTS SHOULD BE
ALERT FOR LATER STATEMENTS OR WARNINGS...AND TAKE ACTION TO
PROTECT PROPERTY.
