What happened

The episode as NWS OKX wrote it up.

A Nor Easter occurred during Sunday and Monday, April 15th and 16th. It brought heavy rain and high winds that caused widespread and significant river, stream, and urban flooding of low lying and poor drainage areas. High winds downed many trees and power lines across Eastern Suffolk County. The combination of high winds, heavy rain, and high water tables produced widespread moderate tidal flooding across parts of the New York City and Long Island Sound shores through Thursday, April 19th. Significant river flooding lasted through April 17th.|Storm Total Rainfall amounts ranged from 1.47 inches at Lindenhurst to 8.41 inches at Central Park:|Nassau County rainfall ranged from 1.54 inches at Oceanside to 3.60 inches at East Meadow.|New York City rainfall ranged from 2.70 inches at JFK Airport to 8.41 inches at Central Park. At LaGuardia Airport, 7.00 inches was measured.|Orange County rainfall ranged from 4.26 inches in Westtown to 8.00 inches at Cornwall.|Suffolk County rainfall ranged from 1.47 inches at Lindenhurst to 5.41 inches at Greenlawn.|Westchester County rainfall ranged from 5.85 inches in Yorktown Heights to 8.22 inches in East White Plains.|Flooding from Rainfall:|Many small rivers, streams, and brooks rose over their banks within 12 hours of the heavy rainfall during Sunday, April 15th. The Wallkill River rose over its' banks the following day, on Monday, April 16th.|The Orange County Department of Emergency Services reported emergency declarations in the towns of Deerpark and Blooming Grove and in the villages of Washingtonville, Greenwood Lake, and South Blooming Grove. Many road closures were reported in the towns of Newburgh, Blooming Grove, Cornwall, Crawford, Deerpark, Walkill, and many other towns and villages throughout the county. Evacuations occurred in the towns of Woodbury, Tuxedo, Deerpark, and Washingtonville.|River Flood Observations include:|In Orange County, the Wallkill River at Gardiner rose to its' flood stage of 13 feet at 8:15 am on April 16th, crested at 14.9 feet at 7:08 pm on April 16th, then fell below flood stage at noon on April 17th.|Urban Flood Observations include:|Brooklyn - Street flooding was reported along the Belt Parkway.|Manhattan - Street flooding was reported along the FDR Drive.|Orange County - Moodna Creek flooded at Washingtonville. Houses were flooded.|Putnam County - The Taconic State Parkway and I-84 intersection near Miller Hill Road was flooded.|Queens - A partial road closure was reported along the Van Wyck Expressway at Jewel Avenue.|Rockland County - The south bound lanes closed near the intersection of Route 9 and Broadway.|Westchester County - NY State Police reported flooding closures at Exit 7 of I 287, Exits 18A, 18B, and 22 of I 95, and I 95 south bound between exits 19 and 17. A spotter reported a partial road closure along the Hutchinson River Parkway at Linden Avenue in Harrison. The Bronx River Parkway was closed in White Plains.|High Wind Observations include:|East winds increased during the day, Sunday as the low approached. Wind speeds gusted from 35 to 55 mph. As the low moved toward Long Island, another period of high winds occurred during Sunday night with peak wind speeds from 45 to 55 mph.|Peak wind gusts in mph on April 15th included:|Bronx County - |47 mph at Maritime College NERON site at 1:41 pm|Queens County - |48 mph from the east at JFK Airport|Nassau County - |45 mph from the east at Farmingdale Republic Airport|41 mph at Merrick at 5:59 pm|Suffolk County - |61 mph from the east at 1:45 pm at Shinnecock Inlet|56 mph at 9:25 pm at Baiting Hollow|56 mph around 9 pm at Brookhaven National Lab|51 mph from the east at Islip McArthur Airport|50 mph at Fire Island NERON site|Tidal Flood Observations include:|Widespread moderate to major beach erosion occurred across the south and east shores of Long Island. Moderate coastal flooding occurred along the Atlantic and Long Island Sound shores of New York City and Long Island around the times of high tide starting Sunday evening, and lasting through Thursday, April 19th. The highest surges of 3 to 4 feet occurred across the Atlantic shores of Suffolk County during Sunday evening. Because of the new moon on April 17th, the highest water levels (and highest tidal departures) occurred during Tuesday, April 17th. Water slowly receded during the remainder of the week, when mainly minor tidal flooding occurred during Wednesday and Thursday.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE UPTON NY
414 AM EDT SUN APR 15 2007

.SYNOPSIS...
LOW PRESSURE...OVER WESTERN NORTH CAROLINA EARLY THIS MORNING...WILL
MOVE ACROSS THE DELMARVA EARLY THIS AFTERNOON...AND THEN EXPLOSIVELY
DEEPEN AS IT SLOWLY TRACKS TOWARDS NEW YORK CITY TONIGHT. THE LOW THEN
MOVES ACROSS NYC INTO THE LOWER HUDSON VALLEY MONDAY MORNING...AND
THEN LOOPING BACK OVER THE REGION MONDAY INTO MONDAY EVENING AS IT
FILLS...BEFORE MOVING EAST LATE MONDAY NIGHT. THE LOW CONTINUES TO
MOVE SLOWLY MOVE EAST THROUGH WEDNESDAY. THE STORM WILL POSE A
VARIETY OF WEATHER PROBLEMS FOR THE LOCAL AREA SUNDAY THROUGH AT
LEAST TUESDAY. HIGH PRESSURE WILL THEN BUILD SLOWLY INTO THE
REGION FROM THE NORTH THURSDAY THROUGH SATURDAY.

&&

.NEAR TERM /THROUGH MONDAY MORNING/...
DEVELOPING FULL LATITUDE UPPER TROUGH IS SWINGING THROUGH THE
MISSISSIPPI VALLEY EARLY THIS MORNING AS UPPER TROUGH AXIS SLIDES
OFFSHORE. THE UPPER TROUGH WILL REACH NEUTRAL TILT EARLY THIS
AFTERNOON FROM UPPER GREAT LAKES TO GULF COAST...WITH DEEP SW FLOW
CONTINUING TO BACK TO SOUTHERLY UP THE EAST COAST. AT THE
SURFACE...LOW PRESSURE OVER WESTERN N CAROLINA EARLY THIS MORNING
WILL SLOWLY TRACK NE TOWARDS THE MID-ATLANTIC WHILE INTENSIFYING
THIS MORNING. RAIN WILL CONTINUE TO OVERSPREAD THE AREA EARLY THIS
MORNING FROM SW TO NE IN RESPONSE TO STRONG THETA-E ADVECTION AND
ISENTROPIC LIFT IN DEVELOPING DIFFLUENT FLOW ALOFT AND AHEAD OF
DEVELOPING 70 LT LOW-LEVEL JET UP THE MID-ATLANTIC COAST.

MODELS HAVE COME INTO GOOD AGREEMENT WITH MAIN SYNOPTIC FEATURES
TODAY INTO THIS EVENING...WITH THE ELONGATING CLOSED LOW OVER
EASTERN ONTARIO PHASING WITH STRONG SHORTWAVE ENERGY ROUNDING THE
BASE OF THE UPPER TROUGH AND RIDING UP EAST COAST ON FRONT SIDE OF
NEGATIVELY TILTING UPPER TROUGH BY THIS EVENING...RESULTING IN A TWO
A 2-3 STD BELOW NORMAL CLOSED LOW ACROSS CENTRAL PA.

THIS IS A WESTWARD AND SLOWER PLACEMENT AND EVOLUTION THAN
PREVIOUS DAYS RUNS...BUT IN GENERAL WELL IN LINE WITH THE MOST
CONSISTENT ECMWF/GEM SOLUTIONS OF THE PAST FEW DAYS. IN FACT 00Z
GFS/12Z ECMWF/00Z CAN REG ARE IN VERY GOOD AGREEMENT...WITH NAM JUST
A BIT FARTHER EAST.

SO AT THE SURFACE...MODELS IN AGREEMENT TRACKING THE LOW PRESSURE
THROUGH THE DELMARVA EARLY THIS AFTERNOON AND THEN RAPIDLY
INTENSIFYING AS IT TRACKS UP THE NJ COAST LATE THIS AFTERNOON
THROUGH TONIGHT...IN RESPONSE TO PHASING UPPER ENERGIES.

RAIN BECOMES HEAVY FROM SW TO NE FROM AROUND DAYBREAK THROUGH
MID-MORNING AND CONTINUES THROUGH THIS EVENING WITH STRONG SYNOPTIC
ASCENT IN DIFFLUENT UPPER FLOW...AND AS A WIDE BAND OF 700-850
FRONTOGENIC FORCING DEVELOPS IN TIGHTENING BAROCLINIC ZONES TO THE
N/NE OF BOMBING LOW PRESSURE MOVING TOWARDS LI. COPIOUS MOISTURE AND
ADDITIONAL LIFT BEING PROVIDED BY 70-75 KT LLJ DEVELOPING TO THE EAST
SIDE OF THE SURFACE LOW BRINGING IN 2-3 STD ABOVE NORMAL PWAT
AIR...AND THEN DUMPING IT OVER THE REGION WITH 4-5 STD ABOVE NORMAL
850 U-WIND COMPONENT. THE PERFECT COMBINATION FOR A HEAVY PRECIP
EVENT OVER THE AREA.

PRECIP WILL BE HEAVY...AND 2 TO 4 INCHES OF LIQUID QPF EXPECTED
THROUGH AROUND 06Z TONIGHT. SO FLOOD WATCH WILL BE CONTINUED FOR
ALL OF REGION THROUGH 08Z.

WINDS WILL INCREASE RAPIDLY LATE THIS MORNING AHEAD OF BOMBING LOW
PRESSURE...WITH A 55-60 KT 950 HPA SE LLJ DEVELOPING. A GOOD
PERCENTAGE OF THESE WINDS SHOULD BE ABLE TO MIX DOWN THROUGH LATE
AFTERNOON...FOR A PERIOD OF WINDS OF 40 MPH OR GREATER SUSTAINED
AND GUSTS TO AROUND 58 MPH EXPECTED BETWEEN 2 PM AND 8 PM THIS
AFTERNOON ACROSS SUFFOLK COUNTY LI AND COASTAL SE CONN WHERE THE
INTENSIFYING LLJ WILL CROSS REGION AHEAD OF BOMBING LOW PRESSURE.
AWAY FROM THE IMMEDIATE COAST...GREATER THREAT MAY BE FOR THE
DAMAGING WIND GUSTS IN THE WARNING AREA AS THE LLJ WILL COINCIDE
WITH HEAVY RAINFALL. ALONG THE IMMEDIATE COAST OF THE WARNING
AREA...WITH STORM FORCE WINDS EXPECTED ON THE EASTERN WATERS...A
PERIOD OF SUSTAINED WINDS OF 40 TO 45 MPH ARE LIKELY ACROSS THE
ADJACENT COASTAL SECTIONS IN ADDITION TO THE GUSTS. ALTHOUGH LLJ
WILL REMAIN STRONG LATE INTO THE EVENING ACROSS FAR EASTERN
SECTION OF THE AREA...STRONG WAA SHOULD STRENGTHEN LOW LEVEL
INVERSION AND BEGIN TO CUT OF WINDS MIXING TO THE SURFACE.

NOT CONFIDENT ON EXTENDING THE HIGH WIND WARNING ANY FURTHER WEST
AS THE INTENSIFYING LLJ WILL TRACK S AND E OF THIS REGION THIS
AFTERNOON. SO EXPECTING EASTERLY WINDS OF 25 TO 35 MPH WITH GUSTS
UP TO 50 MPH ACROSS ALL OF THE REMAINDER OF THE COASTAL AREA
INCLUDING NYC. SO WILL CONTINUE HIGH WIND WARNING/WIND ADVISORY
FROM NOON THROUGH MIDNIGHT DURING PERIOD OF STRONGEST GRADIENT.

HEAVIEST MOISTURE/LIFT AXIS LIFTS SLOWLY N AND NE OF THE REGION BY
AROUND 06Z TONIGHT AS SURFACE LOW APPROACHES NYC WITH DRY SLOT
TRYING TO WORK INTO EASTERN PORTIONS OF THE REGION. DOESNT APPEAR
REGION EVER GETS FULLY INTO THE DRY SLOT...AS THE NEWLY PHASED
CLOSED LOW SLIDES EASTWARD TOWARDS THE REGION THIS EVENING...THE
SURFACE LOW WILL VERTICALLY STACK UNDER IT ACROSS LI/SOUTHERN CONN BY
MON MORNING. SO EXPECT WIDESPREAD LIGHT RAIN TO CONTINUE ACROSS THE
REGION TONIGHT WITH COMBINATION OF VORT ENERGY AND WRAPAROUND
LOW/MID-LEVEL MOISTURE AROUND THE SURFACE LOW.

WINDS SHOULD BEGIN TO SUBSIDE LATE THIS EVENING INTO THE OVERNIGHT
AS LOW-LEVEL INVERSION STRENGTHENS AND LOW PRESSURE BEGINS TO
OVERRIDE THE AREA.

WITH MODEL CONSENSUS ON A WARMER AND FURTHER WESTWARD TRACK...STILL
LOOKS LIKE MAINLY A RAIN EVENT FOR ORANGE COUNTY NY. BEST CHANCE FOR
SOME SN OR IP TO MIX IN WILL BE THIS MORNING AS STRONG LIFT
DYNAMICALLY/EVAP COOLS MARGINALLY COLD LOW-LEVEL...BUT THAT WOULD BE
SHORT LIVED WITH ACCUM LESS THAN AN INCH AS STRONG WAA IN THE
700-850 LEVELS WARMS TO ALL LIQUID. AND SINCE LOW PRESSURE STACKS
OVER THE REGION...SUFFICIENT CAA FOR SN DOES NOT LOOK LIKELY UNTIL
MON NIGHT.

TEMPS WILL RUN ABOUT 10 TO 15 DEGREES BELOW SEASONABLE TODAY WITH
CLOUD COVER AND ONSHORE FLOW...BUT THEN RUN NEAR SEASONABLE TONIGHT
WITH WAA AROUND DEEP LOW AND CLOUD COVER.

&&

.SHORT TERM /MONDAY MORNING THROUGH TUESDAY/...
PREFERRED GFS/ECMWF/UKMET/GEM BLEND IN GOOD AGREEMENT WITH STACKED
976-976 HPA LOW OVER NYC MON MORNING...LOOPING INTO LOWER HUDSON
VALLEY DURING THE AFTERNOON AND THEN BEGINNING TO FILL AS IT WORKS
BACK THROUGH NYC THROUGH MON EVENING. THE STACKED LOW THEN
CONTINUES TO SLOWLY FILL AS IT SLIDES EAST MONDAY NIGHT INTO
TUESDAY. WITH POSITION OF LOW ACROSS WESTERN HALF OF CWA ON MONDAY
WILL SEE HIGHER CAT POPS IN FORM OF INSTABILITY -SHRA ACROSS
WESTERN HALF OF THE REGION WITH COLD POOL/VORTEX ENERGY
ALOFT...LIKELY POPS TO THE SE..

COLUMN COOLS ENOUGH ON BACKSIDE OF VORTEX MONDAY NIGHT FOR SN TO MIX
IN FROM N TO S. LIGHT ACCUM POSSIBLE ACROSS HIGHER ELEVATION OF
INTERIOR LOWER HUDSON VALLEY. BOUNDARY LAYER WARMING WITH APRIL
SUN...WILL HAVE ANY SN CHANGING TO RAIN TUES MORNING.

POPS LOWER TO LIKELY ON TUES AS CLOSED LOW FURTHER WEAKENS AND
SLIDES SE AWAYS FROM THE AREA...BUT STILL ENOUGH WRAPAROUND MOISTURE
AND SHORTWAVE ENERGY IN DEEP CYCLONIC FLOW TO SPARK PERIODS OF
SHOWERS.

HAVE GONE A FEW DEGREES BELOW GUIDANCE DURING THE DAY WITH CLOUD
COVER AND CAA FLOW...WITH TEMPS GENERALLY ABOUT 10 DEGREES BELOW
SEASONABLE DURING THE PERIOD.

&&

.LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
THE UPPER LOW AND SURFACE LOW WILL BE SLOW TO MOVE EAST OF THE
AREA TUESDAY NIGHT INTO WEDNESDAY NIGHT. WITH UPPER TROUGH
ROTATING AROUND THE UPPER LOW AND CYCLONIC FLOW INFLUENCING THE
REGION AT THE SURFACE THERE WILL BE CHANCES FOR PRECIPITATION FROM
TUESDAY NIGHT INTO WEDNESDAY NIGHT. SURFACE RIDGING DOES BEGIN TO
BUILD INTO THE AREA LATE WEDNESDAY NIGHT. BY THURSDAY SURFACE HIGH
BUILDS INTO THE AREA WITH UPPER RIDGING THURSDAY NIGHT INTO THE WEEKEND.
SOME LINGERING COLD AIR LATE TUESDAY NIGHT WILL CHANGE ANY
PRECIPITATION TO SNOW OR MIXED WITH RAIN ACROSS THE NORTHERN TIER.

&&

.AVIATION /08Z SUNDAY THROUGH THURSDAY/...
RAIN WILL START TO OVERSPREAD THE REGION THROUGH 10Z FROM WEST TO
EAST. IT WILL BE LIGHT AT FIRST...WITH VFR CIGS AND VSBYS EXPECTED
TO PREVAIL INITIALLY. ABOUT 1-2 HOURS AFTER THE ONSET OF
RAIN...VSBYS SHOULD LOWER TO MVFR.

EAST WINDS PICK UP AROUND OR SHORTLY AFTER DAYBREAK...MOSTLY
20-25 KT SUSTAINED AND GUSTS TO 30 KT...INCREASING TO AROUND 25 KT
WITH GUSTS TO 40 KT LATE IN THE MORNING. A LOW LEVEL JET (WINDS
NEAR 50 KT AT AROUND 1500 FT) WILL BRUSH THE AREA NEAR NOONTIME ON
SUNDAY. LOW LEVEL WIND SHEAR MAY BE A CONCERN STARTING LATE IN THE
MORNING. GUSTS WILL INCREASE DURING THIS TIME TO NEAR 40 KT...BUT
NOT AS STRONG AT SWF AS THEY WILL BE FARTHER AWAY FROM THE LOW
LEVEL JET. EASTERN TERMINALS COULD SEE 45 TO 50 KTS IN ANY HEAVIER
CONVECTION. LLWS WILL BE LEFT OUT OF THE TAFS AT THIS TIME DUE TO
THE STRONG SURFACE WINDS EXPECTED.

LIGHT RAIN WILL TRANSITION TO MODERATE RAINFALL AROUND 12-13Z...WITH
CIGS AND VSBYS LOWERING TO LOWER-END MVFR. AS THE LOW LEVEL JET
AND STRONGER FORCING APPROACHES LATE SUNDAY MORNING...HEAVY RAIN
AND IFR CIGS AND VSBYS EXPECTED THROUGH THE AFTERNOON.

THE CENTER OF LOW PRESSURE WILL APPROACH THE REGION SUNDAY
EVENING. AS THE LOW MOVES ALMOST OVERHEAD THE LOW LEVEL JET WILL
BE DISPLACED EAST OF THE AREA...AND THE LOCAL PRESSURE GRADIENT
WILL RELAX DUE TO THE PROXIMITY OF THE LOW. THIS WILL RESULT IN A
LIGHTENING OF BOTH THE RAIN AND THE WINDS THIS EVENING. WIND
DIRECTION WILL BE PARTICULARLY TRICKY FROM LATE AFTERNOON INTO
TONIGHT...AS EVEN A 15 MILE SHIFT IN THE POSITION OF THE LOW COULD
MEAN A 90 TO 180 DEGREE CHANGE IN THE WIND DIRECTION. CONFIDENCE
IS HIGH IN THE DECREASE OF WINDS FOR TONIGHT...BUT THE SAME CAN
NOT BE SAID ABOUT A DETERMINISTIC WIND DIRECTION FORECAST.

OUTLOOK BEYOND 06Z SUN...IFR OR LOWER CIGS/VSBYS WILL BE EXPECTED
ON MONDAY. WIND DIRECTION AND MAGNITUDE WILL CONTINUE TO BE HIGHLY
DEPENDENT ON THE EXACT POSITION OF THE LOW...WHICH IS EXPECTED TO
MEANDER NEARBY THROUGH MONDAY. WINDS WILL DE DECREASED IN THE
PROXIMITY OF THE LOW...BUT WOULD STRENGTHEN IF THE LOW CAN DRIFT
AWAY. CIGS/VSBYS WILL IMPROVE ON TUE AS THE LOW LIFTS AWAY...BUT
MODERATE TO STRONG NW WINDS WILL BE EXPECTED INTO EARLY WED.

&&

.MARINE...
CURRENTLY OBSERVING LIGHT WINDS ACROSS THE WATERS AS HIGH PRESSURE
RIDGE SLOWLY MOVES EAST. BUT...THIS WILL NOT LAST LONG AS THE
PRESSURE GRADIENT WILL QUICKLY TIGHTEN THIS MORNING AS A DEVELOPING
AREA OF LOW PRESSURE CURRENTLY OVER THE SOUTHERN APPALACHIANS
APPROACHES. THEN...GALE WARNING CONDITIONS EXPECTED TO DEVELOP THIS
MORNING ACROSS NY HARBOR WITH STORM WARNINGS FOR THE REMAINDER OF
THE COASTAL WATERS. THESE STRONG WINDS WILL BE THE RESULT OF A TIGHT
PRESSURE GRADIENT AS 980 HPA LOW APPROACHES AND POTENTIAL MIXING
DOWN FROM AN 80 KT 850 HPA LOW LEVEL JET IN HEAVY RAIN. EXPECT 50 KT
GUSTS TO BE FAIRLY WIDESPREAD FOR A PERIOD THIS AFTERNOON...
ESPECIALLY IN AND AROUND HEAVY RAIN. THE STRONGEST WINDS WILL
PERSIST FROM LATE THIS MORNING THROUGH THE AFTERNOON. THEREAFTER THE
LOW LEVEL JET WILL START TOP SLIDE EAST ACROSS AND EVENTUALLY EAST
OF THE WATERS. AS A RESULT...WILL PERSIST
THE STRONGEST WINDS AND GUSTS A FEW HOURS LONGER ON THE EASTERN
WATERS. RIGHT NOW...THINKING NAM THE CLOSEST TO LOW PRESSURE
MOVEMENT BASED ON SUPPORT FROM HPC/GGEM/ECMWF AND ENSEMBLE DATA. LOW
GOES ACROSS LONG ISLAND SUNDAY NIGHT AND MONDAY..MAYBE INTO SRN
CT...BEFORE SLOWLY PULLING AWAY. GFS MOVES THIS LOW TOO FAR TO THE
NORTH IN MY OPINION. THERE WILL BE A PERIOD OF LIGHTER WINDS TONIGHT
AS THE LOW SLOWLY DRIFTS OVERHEAD...LIKELY RESULTING IN WINDS
DROPPING TO SCA CRITERIA OR BELOW. THEN NORTHERLY AND NORTHWESTERLY
WINDS PICK UP BEHIND THE LOW MONDAY THROUGH TUESDAY.

WAVE WATCH III SEAS FORECASTS LOOK GOOD AND CAN EXPECT UP TO 14 TO
18 FEET OVER THE OCEAN...AND 7 TO 8 FEET COULD BE REALIZED ACROSS
PORTIONS OF THE LI SOUND. SEAS GRADUALLY SUBSIDE MONDAY THROUGH
MONDAY NIGHT.

&&

.HYDROLOGY...
THE POTENTIAL FOR 2-4 INCHES OF RAINFALL POSSIBLE FROM EARLY THIS
MORNING INTO TONIGHT WITH A LIKELIHOOD OF FLOODING OF URBAN
AREAS...LOW LYING AREAS...SMALL STREAMS. LARGER RIVERS WILL LIKELY
SEE SIGNIFICANT RISES THROUGH TUESDAY. WITH VERY HEAVY RAINFALL
TODAY FLOODING OF LOW LYING AREAS AND URBAN AREAS MORE LIKELY.
FLOOD WATCH IN EFFECT FOR THE ENTIRE AREA 12Z SUNDAY THROUGH 08Z
MONDAY.

&&

.TIDES/COASTAL FLOODING...
TIDAL DEPARTURES FROM FROM ZERO TO .25 FT ABOVE NORMAL AT THIS TIME.
WINDS STILL HAVE NOT PICKED UP...SO WE LIKELY WILL BE ABLE TO GET BY
THIS MORNINGS HIGH TIDE WITHOUT ANY PROBLEMS. THE ONLY EXCEPTION MAY
BE ON WESTERN LONG ISLAND SOUND...AS THE LATER TIME OF HIGH TIDE MAY
ALLOW TIDAL DEPARTURES AMPLE TIME TO PRODUCE WATER LEVELS
APPROACHING MINOR FLOODING BENCHMARKS. HOWEVER...THE FEELING IS THAT
WE WILL FALL SHORT WITH TIDAL DEPARTURES GENERALLY ABOUT 1 FT ABOVE
NORMAL (1.5 FT IS NEEDED).

A VERY STRONG EASTERLY FLOW DURING THE DAY TODAY WILL RESULT IN
COPIOUS AMOUNTS OF WATER BEING PUSHED INTO LONG ISLAND SOUND...AND
ALONG THE SOUTH SHORE OF LONG ISLAND. EXPECTED TIDAL DEPARTURES FOR
THE HIGH TIDE CYCLE THIS EVENING WILL RESULT COASTAL FLOODING.
MODEL GUIDANCE IS CURRENTLY PROJECTING 4 TO 6 FT ACROSS WESTERN LI
SOUND AND AROUND 2 TO 4 FT ELSEWHERE. HOWEVER...THIS LOOKS HIGH
CONSIDERING THE SHORT TIME DURATION OF THE STRONG WINDS...GENERALLY
LESS THAN 12 HOURS. GIVEN THAT WATER LEVELS ARE CURRENTLY RUNNING
ABOUT NORMAL...IT SEEMS DIFFICULT TO IMAGINE THAT A 4 FT PLUS
DEPARTURE. PLUS...AS THE CENTER OF LOW PRESSURE MOVES NEARLY
OVERHEAD TONIGHT...THE PRESSURE GRADIENT WILL RELAX. THIS MEANS THAT
TIDAL DEPARTURES WILL LIKELY PEAK BEFORE THE TIME OF HIGH TIDE IN
THE SOUND. WILL FORECAST A TIDAL DEPARTURE OF 3 TO 4 FT IN WESTERN
LONG ISLAND SOUND AND 2 TO 3 FT ELSEWHERE.

FROM A HISTORICAL PERSPECTIVE...DEPARTURES OF THIS MAGNITUDE IN
COMBINATION WITH INCREASING SPRING TIDES DUE TO THE NEW MOON ON THE
17TH WOULD CAUSE COASTAL FLOODING AS SERIOUS AS THAT OF THE COASTAL
STORMS OF MAR 1993 AND OCT 1991. WE WOULD NEED A 4 FOOT DEPARTURE IN
NEW YORK HARBOR AND 5.5 FEET ON WESTERN LONG ISLAND SOUND TO MATCH
THE DECEMBER 1992 NOREASTER. OBVIOUSLY...CONFIDENCE REMAINS HIGH OF
AT LEAST MODERATE AND POSSIBLY MAJOR COASTAL FLOODING THIS EVENING...
SO WILL CONTINUE THE COASTAL FLOOD WARNING. THEREAFTER...WILL
HAVE TO KEEP AN EYE ON TIDES AS THE STORM BASICALLY SITS OVERHEAD.
WINDS WILL LIGHTEN AT THAT POINT...BUT HOW MUCH WATER DRAINS OUT IS
THE QUESTION. WILL WAIT ON SUBSEQUENT TIDE CYCLES.
