..MAJOR NOR'EASTER UNDERWAY ALONG THE EASTERN SEABOARD
...HEAVY RAINFALL CONTINUES OVER THE PACIFIC NORTHWEST AND
NORTH-CENTRAL CALIFORNIA THROUGH MIDWEEK...
THE LATEST SATELLITE IMAGERY THIS MORNING HIGHLIGHTS A MAJOR
NOR'EASTER TAKING ON A CLASSIC "COMMA-HEAD" SHAPE AS IT RAPIDLY
INTENSIFIES OFF THE DELAWARE/NEW JERSEY COASTLINE. OVERALL, THE
FORECAST REMAINS ON TRACK IN TERMS OF EXPECTED IMPACTS WITH THIS
POWERFUL SYSTEM. VERY HEAVY SNOWFALL RATES UPWARDS OF 2-3" PER
HOUR AND GUSTY WINDS OF 40-70 MPH WILL CONTINUE TO BATTER THE
NORTHEAST TODAY, WHILE ALSO SPREADING INTO NEW ENGLAND THIS
MORNING AS THE STORM BEGINS TO ACCELERATE. BY TOMORROW MORNING,
SOME AREAS NEAR THE COASTLINE COULD WAKE UP TO STORM TOTAL
SNOWFALL AMOUNTS OF ONE TO TWO FEET AS THE LOW DEPARTS INTO THE
CANADIAN MARITIMES. FOR TODAY, HOWEVER, THE VERY HIGH SNOWFALL
RATES AND POTENTIALLY DAMAGING WIND GUSTS WILL MAKE TRAVEL NEARLY
IMPOSSIBLE FROM THE DELMARVA PENINSULA INTO SOUTHEASTERN NEW
ENGLAND. BEYOND TOMORROW, A PROGRESSIVE CLIPPER SYSTEM DIVING OUT
OF THE UPPER GREAT LAKES COULD YIELD ADDITIONAL SNOWFALL OVER
PARTS OF THE NORTHEAST, INCLUDING AREAS WHICH ARE SEEING THE HEAVY
SNOW NOW, SO STAY TUNED.
ON THE OPPOSITE COASTLINE, A SERIES OF ATMOSPHERIC RIVERS WILL
DRIVE ADDITIONAL HEAVY RAINFALL WHICH SPREADS SOUTHWARD OUT OF THE
PACIFIC NORTHWEST. OWING TO THE RECENT HEAVY RAINFALL OVER THE
LAST FEW WEEKS, ISOLATED TO SCATTERED INSTANCES OF FLASH FLOODING
ARE POSSIBLE TOMORROW, MAINLY OVER PORTIONS OF NORTH-CENTRAL
CALIFORNIA INCLUDING THE SIERRA NEVADA MOUNTAINS. AS THE SYSTEM
PRESSES EAST BY MIDWEEK, MOUNTAIN SNOWFALL AND LOW ELEVATION RAINS
SHOULD PRESS INLAND TO THE GREAT BASIN, WHICH SHOULD HELP WITH
ALLEVIATING DROUGHT CONDITIONS IN THE REGION.
