Flooding in Virginia, October 29 to 30, 2012

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BALTIMORE MD/WASHINGTON DC
1148 AM EDT MON OCT 29 2012

.SYNOPSIS...
HURRICANE SANDY WAS APPROXIMATELY 315 MILES EAST OF
WASHINGTON D.C. LATE THIS MORNING. THE STORM IS FORECAST TO MOVE
CLOSER TO THE COAST TODAY...AND MOVE INLAND ACROSS SOUTHERN NEW
JERSEY TONIGHT. THE POST-TROPICAL CYCLONE WILL THEN SLOWLY TRACK
INLAND INTO PENNSYLVANIA. THIS LARGE STORM WILL BRING SIGNIFICANT
IMPACTS TO THE ENTIRE REGION THROUGH MIDWEEK. CONDITIONS WILL
IMPROVE DURING THE SECOND HALF OF THE WORK WEEK.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
SIGNIFICANT WIND AND RAIN EVENT TODAY THROUGH TUESDAY. FOR A
CONCISE SUMMARY OF THREATS AND THEIR IMPACTS PLEASE SEE THE LATEST
SPECIAL WEATHER STATEMENT ON SANDY...SPSLWX. THERE IS A LINK TO
THIS IN BIG RED LETTERS AT THE TOP OF OUR WEBPAGE...
WEATHER.GOV/LWX.

THE CENTER OF SANDY WAS LOCATED AROUND 315 MILES EAST OF
WASHINGTON D.C. AT 11 AM. SANDY HAS BEGUN HER NORTHWEST TURN...AND
WILL CONTINUE TO MOVE NORTHWEST TOWARD THE SOUTHERN COAST OF NEW
JERSEY THROUGH TONIGHT. SATELLITE IMAGERY ALSO SUGGESTS THAT THERE
IS STILL SOME STRENGTHENING GOING ON WITH SANDY.

REMEMBER THAT THE IMPACTS EXTEND WELL BEYOND THE CENTER OF THIS
STORM...AND SIGNIFICANT IMPACTS WILL AFFECT THE ENTIRE MID-
ATLANTIC REGION TODAY THROUGH TUESDAY.

WINDS WILL CONTINUE TO INCREASE THROUGH THE AFTERNOON...WITH THE
PERIOD OF STRONGEST WINDS LATE THIS AFTERNOON AND TONIGHT. THESE
WINDS WILL BE EXTREMELY DANGEROUS AND DAMAGING...RESULTING IN MANY
DOWNED TREES/POWER LINES.

MODERATE TO OCCASIONALLY RAIN WILL CONTINUE TO EXPAND WESTWARD
THROUGH THE CWA TODAY...CONTINUING TONIGHT. RAINFALL RATES OF 1
TO 1.5 INCHES AN HOUR MAY OCCUR IN THE HEAVIEST RAIN BANDS. THIS
MAY RESULT IN FLOODING.

AT ELEVATIONS ABOVE 2000 FT ACROSS THE POTOMAC HIGHLANDS...IT WILL
BE COLD ENOUGH FOR ALL OR MOSTLY SNOW AND THE SNOW MAY BE HEAVY AT
TIMES.

HEADLINES REMAIN THE SAME EXCEPT WE WILL BE ADDING A WINTER
WEATHER ADVISORY FOR THE HIGHEST ELEVATIONS OF AUGUSTA AND
ROCKINGHAM COUNTIES.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 AM TUESDAY/...
DANGEROUS WEATHER CONTINUES TONIGHT. THE WESTWARD INLAND TRACK OF
SANDY THEN MUDDIES WITH THE 00Z ECMWF/GFS ALONG THE MASON-DIXON
LINE AND THE 00Z NAM NORTH OF HARRISBURG PA. WIND DIRECTION PLAYS
DIRECTLY INTO THE LOCATION OF THE LOW CENTER. ONLY THING OF
CERTAINTY WIND WISE FOR TONIGHT WAS TO BACK FLOW TO WLY
EARLIER...IN THE EARLY MORNING TIMEFRAME. WIND GUSTS STILL
EXPECTED IN EXCESS OF 60 MPH WITH 70 MPH CERTAINLY
POSSIBLE...PARTICULARLY NORTH FROM DC. WILL HAVE TO WATCH FOR
WESTERLY FLOW LIMITING PRECIP LATE TONIGHT.

&&

.LONG TERM /TUESDAY THROUGH SUNDAY/...
WE ARE CONCERNED BECAUSE THE MDLS ARE IN CONSENSUS REGARDING THE CUTOFF
LOW STALLING OVR CENTRAL MD TUE. HVY RAINS WILL EXACERBATE THE FLD
THREAT. AN XCLNT HYDRO SXN IS BLO.

THERE RMNS PTNTL FOR A PROLONGED UPSLOPE SNOW IN THE FAR WEST. MAIN
FOCUS SHOULD BE ON IMPACTS...WHICH LOOK TO BE SIGNIFICANT. IT'S
PRETTY AMAZING TO SEE THAT JUST LAST YR - OCT 29/30...A NOR'EASTER
BROUGHT HVY WET SNOW FM THE HIGHER ELEVS OF ERN W.V./WRN MD TO NEW
ENGLAND. THIS CAUSED SIGNIFICANT POWER OUTAGES IN THE NERN U.S.
FEAR IS THIS IMPACT WL HAPPEN AGN. METEOROLOGICALLY THIS STORM IS
SOMEWHAT UNCHARTERED TERRITORY...AND SNOWFALL AMTS ARE DIFFICULT
TO GET AN EXACT HANDLE ON. ELEVATION LOOKS TO BE A KEY FACTOR. FOR
NOW WE ARE LOOKING AT 2000 FT AS BEING THE KEY HGT. IN HIGHLAND CO
THE TOWN OF MONTEREY IS AT 2900 FT. DRIVING N TO PENDLETON CO THE
ELEVATION IN FRANKLIN IS 1800 FT - THIS COULD LEAD TO BIG
DIFFERENCES IN TOTALS FOR TOWNS JUST 21 MILES APART.

THE THREAT OF UPSLOPE SNOW CONTINUES THRU MUCH OF THE WK...PROBABLY
INTO THURSDAY. THERE IS A SMALL RISK OF PRECIPITATION MAKING IT EVEN
BEYOND THE WESTERN FRONT INTO THE REST OF THE HIGHLANDS... MAYBE
EVEN UP TO THE BLUE RIDGE.

E OF THE MTNS...2ND HALF OF THE WK WILL BE THE CALM AFTER THE STORM.
TEMPERATURES WILL BE 5 TO 10 DEGREES BELOW NORMAL THROUGHOUT THE
PERIOD...WITH HIGHS MAINLY IN THE 50S IN LOWS IN THE UPPER 30S TO
AROUND 40.

&&

.AVIATION /15Z MONDAY THROUGH FRIDAY/...
CONDITIONS WILL CONTINUE TO DETERIORATE THROUGH THE AFTERNOON AS
SANDY MOVES NORTHWEST CLOSER TO THE COAST. THIS MEANS WINDS WILL
SIGNIFICANTLY INCREASE...WITH WIND GUSTS ABOVE 50 KT BEGINNING
THIS AFTERNOON AND CONTINUING TONIGHT. BANDS OF HEAVY RAINFALL ARE
LIKELY TO BRING IFR VSBYS IN TANDEM WITH THE STRONG WINDS...AND
CIGS MAY ALSO EVENTUALLY LOWER INTO IFR LATER TODAY. WIND AND RAIN
CONTINUE TONIGHT. RAIN MAY START TO TAPER OFF ON TUESDAY BUT IT
WILL STILL BE ON THE WIND SIDE.

CONDITIONS WILL SLOWLY IMPROVE TUESDAY NIGHT AND NO IMPACTS TO
AVIATION ARE EXPECTED FOR THE SECOND HALF OF THE WEEK AT THE MAJOR
TERMINALS.

&&

.MARINE...
HURRICANE FORCE WIND WARNING...PARTICULARLY FOR NW WINDS GUSTING
50 TO POSSIBLY 65 KT THIS AFTERNOON AND EVENING GOING DOWN THE
BAY. STORM WARNING FOR MID AND UPR TIDAL POTOMAC WITH GUSTS UP TO
55 KT TONIGHT.

WINDS REACHING/EXCEEDING SCA CRITERIA WILL CONTINUE ACROSS THE
MARINE AREA THROUGH AT LEAST WEDNESDAY...AND I ACTUALLY HAVE WIND
GUSTS MEETING SCA CRITERIA IN AT LEAST A PORTION OF THE WATERS
THROUGH MOST OF THE FORECAST PERIOD. HIGH PRESSURE COULD BUILD IN
AND WEAKEN THE WIND FIELDS BY NEXT WEEKEND.

&&

.HYDROLOGY...
WE HV 5-9 INCHES OF RAIN POSSIBLE IN THE I-270 CORRIDOR THROUGH
THE DC METRO AREA AND DOWN THROUGH SOUTHERN MARYLAND. AMOUNTS
COULD BE EVEN HIGHER CLOSE TO THE BAY. 3-5 INCHES OF RAIN IS
EXPECTED IN THE NORTHERN HIGHLANDS AND RAPPAHANNOCK BASIN...WITH
LOWER AMOUNTS OF JUST 1-3 INCHES IN THE STAUNTON/WAYNESBORO/
CHARLOTTESVILLE/HARRISONBURG AREAS.

OUR RAINFALL PROJECTIONS HAVE OVER AN INCH OF RAIN PER SIX HOUR
PERIOD FOR 24 HOURS IN THE AREA WHERE THE HEAVIEST RAIN IS
ANTICIPATED. SOME FLASH FLOODING WOULD OCCUR IF MORE THAN THIS IS
EXPECTED...AND IS ALSO POSSIBLE WITH LOWER AMOUNTS IN AREAS WHERE
FALLEN LEAVES /OR PERHAPS OTHER WIND-DRIVEN DEBRIS/ MAY CLOG
DRAINAGE SYSTEMS. THESE FACTORS ALSO APPLY FOR LONGER-DURATION
STREAM FLOODING...WHICH IS LIKELY TO BE SIGNIFICANT AND LENGTHY...
EVEN ON STREAMS THAT ARE USUALLY FAST TO RISE AND FALL.

THE FLOOD THREAT BEGINS LATE TONIGHT. THE SMALLER STREAM AND URBAN
FLOOD THREAT CONTINUES THROUGH TUESDAY. THEN WE TURN ATTENTION TO
THE RIVER FORECAST LOCATIONS. AT THIS TIME...FIVE OF THOSE POINTS
/CONOCOCHEAGUE...MONOCACY...OPEQUON...SENECA...AND ANTIETAM/ ARE
FORECAST TO GO TO FLOOD. WE HAVE BEEN INCLUDING THAT IN THE FLOOD
WATCH BUT WARNING DECISIONS WILL LIKELY COME TONIGHT OR TOMORROW IF
THE FORECASTS HOLD...WHICH SO FAR...THEY HAVE.

IF EVERYTHING PLAYS OUT AS FORECAST...THE CREST MAY NOT GET DOWN TO
LITTLE FALLS UNTIL FRIDAY OR SATURDAY.

&&

.TIDES/COASTAL FLOODING...
NORTHERLY FLOW INCREASING THROUGH THE DAY. NORTHERN PART OF THE BAY
WILL SEE BLOW OUT THROUGH THIS EVENING...BEFORE THE QUICKLY SURGING
BACK UP THE BAY TUESDAY MORNING. WILL DROP THE COASTAL FLOOD
ADVISORY FOR ANNE ARUNDEL AND NORTH FOR TODAY...THEN CONTINUE THE
COASTAL FLOOD WARNING FOR LATE TONIGHT THROUGH TUESDAY NIGHT.

OF WASHINGTON DC. SANDY WAS MOVING NORTHWEST AT 18 MPH...WITH
MAXIMUM SUSTAINED WINDS OF 90 MPH. SANDY IS FORECAST TO MAKE
LANDFALL ALONG THE SOUTHERN NEW JERSEY COAST EARLY TONIGHT...WITH
A LITTLE STRENGTHENING POSSIBLE BEFORE LANDFALL. SANDY WILL
SEVERELY IMPACT THE REGION WELL BEFORE IT COMES ASHORE.

SUMMARY OF THREATS
------------------
* THE MAIN IMMEDIATE THREATS FOR SANDY WILL BE STRONG WINDS
  RESULTING IN WIDESPREAD DOWNED TREES AND POWER/COMMUNICATIONS
  OUTAGES...AND HEAVY RAINS WHICH WILL RESULT IN EXTENSIVE
  FLOODING OF LOCAL STREAMS AND CREEKS.
* BLIZZARD CONDITIONS ARE FORECAST IN THE POTOMAC HIGHLANDS AT
  ELEVATIONS ABOVE 2000 FEET WHERE 18 TO 24 INCHES ARE FORECAST.
* MAJOR RIVER FLOODING IS LIKELY TO OCCUR...STARTING THIS
  AFTERNOON ON SMALLER WATERSHEDS WHICH WILL LEAD TO FLOODING ON
  THE MAIN-STEM RIVERS SUCH AS THE POTOMAC AND THE SHENANDOAH.

CHANGES SINCE LAST LOCAL STATEMENT
----------------------------------
* THE TIMING OF THE PEAK WINDS FROM SANDY ARE NOW EXPECTED FROM
  LATE THIS AFTERNOON TO DAYBREAK ON WEDNESDAY.
* RAINFALL AMOUNTS HAVE BEEN INCREASED. THE GREATER BALTIMORE
  METRO AREA IS NOW FORECAST TO RECEIVE 8 TO 12 INCHES OF
  RAIN...WITH LOCALLY HIGHER AMOUNTS.
* THE POTOMAC RIVER IS LIKELY TO GO INTO FLOOD STAGE BEGINNING
  AROUND WEDNESDAY AND LASTING THROUGH FRIDAY.

HIGH WINDS
----------
* WINDS WILL INCREASE STEADILY TODAY...WITH THE MAXIMUM WIND GUSTS
  OCCURRING LATE THIS AFTERNOON THROUGH TUESDAY MORNING.
* GENERALLY...SUSTAINED WINDS OF 30 TO 50 MPH WITH GUSTS TO 60 MPH
  CAN BE EXPECTED ACROSS THE ENTIRE REGION.
* HURRICANE FORCE WIND GUSTS OF 70 AND POSSIBLY 80 MPH ARE
  EXPECTED TO IMPACT A REGION LOCATED BETWEEN BEL AIR MD...POINT
  LOOKOUT MD...AND HAGERSTOWN MD BETWEEN 6 PM THIS EVENING TO 6 AM
  TUESDAY. THIS INCLUDES THE GREATER BALTIMORE AND WASHINGTON
  METROPOLITAN AREAS.
* COUPLED WITH HEAVY RAINS FROM SANDY...THE HIGH WINDS WILL RESULT
  IN SIGNIFICANT TREE DAMAGE AND POWER LINE DAMAGE.

RAINFALL AND FLOODING
---------------------
* 8 TO 12 INCHES OF RAIN IN NORTHEAST AND NORTH CENTRAL MD
  INCLUDING THE BALTIMORE METRO AREA AND ALONG THE WEST SHORE OF
  THE BAY.

* THIS AMOUNT OF RAIN WILL LIKELY RESULT IN EXTENSIVE AND DANGEROUS
  FLOODING OF LOCAL STREAMS AND CREEKS STARTING THIS AFTERNOON AND
  LASTING INTO WEDNESDAY.

MAIN-STEM RIVER FLOODING
------------------------
* THE POTOMAC RIVER WILL LIKELY START FLOODING TUESDAY NIGHT AND
  CONTINUE THROUGH THE END OF THE WEEK.
* THE MONOCACY RIVER IS FORECAST TO FLOOD LATER TODAY AND CONTINUE
  TO BE IN MAJOR FLOOD THROUGH EARLY THURSDAY. LEVELS FORECAST
  HAVE NOT BEEN SEEN SINCE AGNES IN 1972.

COASTAL FLOODING
----------------
* WITH THE FULL MOON ON MONDAY...ASTRONOMICAL TIDES ARE ALREADY
  HIGHER THAN NORMAL. COUNTER TO THE HIGHER THAN NORMAL
  ASTRONOMICAL TIDES...STRONG NORTH AND NORTHWESTERLY WINDS
  TODAY WILL CAUSE A BLOW-OUT TIDE ALONG THE WESTERN SHORE OF THE
  CHESAPEAKE AND THE TIDAL POTOMAC RIVER TODAY. EAST FACING BEACHES
  ALONG THE TIDAL POTOMAC WILL EXPERIENCE WIND-DRIVEN WAVES THAT
  WILL GIVE THE APPEARANCE OF TIDAL FLOODING AND RESULT IN SIMILAR
  IMPACTS.
* AS WINDS BECOME SOUTHWESTERLY TUESDAY...WATER WILL RETURN BACK
  INTO THE BAY AND TIDAL POTOMAC AND BEGIN TO PILE UP IN THE BAY
  NORTH OF POOLES ISLAND AND IN THE UPPER REACHES OF THE TIDAL
  POTOMAC AND ALONG SOUTH FACING SHORES.
* THE HIGHEST TIDES FOR MOST WILL BE WITH THE HIGH TIDES TUESDAY.

SNOWFALL
--------
* IN THE POTOMAC HIGHLANDS ABOVE 2000 FEET HEAVY WET SNOW IS EXPECTED.
* THE COMBINATION OF STRONG WIND AND HEAVY WET SNOW WILL DOWN
  TREE LIMBS AND POWER LINES. BLIZZARD CONDITIONS ARE FORECAST
  WITH VISIBILITY NEAR ZERO IN PERIODS OF HEAVY SNOW.
* THE HIGHEST ELEVATIONS OVER 3000 FEET ARE EXPECTED TO SEE 18 TO
  24 INCHES BETWEEN LATE THIS AFTERNOON AND WEDNESDAY MORNING.
  SOME ADDITIONAL ACCUMULATION IS EXPECTED THROUGH FRIDAY.

PRECAUTIONARY/PREPAREDNESS ACTIONS
