DISCUSSION
KEY MESSAGE 1
BASED ON SIMILAR CONDITIONS TO WHAT WE SAW ACROSS THE AREA ON
FRIDAY, WITH CONTINUED S/SE SWELLS AROUND 3 FT 8 SECONDS AND
SOUTH WINDS THE HIGH RIP CURRENT RISK CONTINUES THROUGH THIS
EVENING. THE SWELL DIRECTION IS NEARLY PERPENDICULAR TO THE
COASTLINE, MAXIMIZING WAVE HEIGHTS IN THE SURF ZONE TO NEAR 4 FT.
THE SWELLS REMAIN NEAR 3 FT SUNDAY BUT THEIR PERIOD DECREASES
SLIGHTLY TO 7 SECONDS. THE FORECAST WINDS WILL BE MORE
SOUTHEAST IN A GENERAL RANGE OF 10-15 KT. THE RESULTING RIP
CURRENT RISK IS MODERATE FOR THE OCEAN BEACHES BUT THE RIP
CURRENT RISK COULD OCCASIONALLY BE HIGH SUNDAY AFTERNOON
ESPECIALLY IF WINDS END UP BEING HIGHER THAN FORECAST.
A LONG FETCH OF SOUTHERLY FLOW DEVELOPS SUNDAY NIGHT INTO MONDAY,
HELPING BUILD WAVES. OCEAN SEAS AND SWELLS ARE FORECAST TO BUILD
TO NEAR 8 FT MONDAY WITH AROUND 15-20 KTS OF SOUTHERLY SURFACE
WINDS. THIS WILL EASILY RESULT IN A HIGH RISK OF RIP CURRENTS.
IF THE WAVE FORECAST REMAINS NEAR 8 FT IN SUBSEQUENT FORECASTS,
A HIGH SURF ADVISORY MAY BE NEEDED.
KEY MESSAGE 2
NWP AND AI GUIDANCE CONTINUES TO POINT TO THE POTENTIAL FOR A PERIOD
OF HEAVY RAINFALL BEGINNING SOME TIME SUNDAY NIGHT. THE RISK OF
HEAVY RAINFALL AND POSSIBLE IMPACTS LOOK TO CONTINUE INTO A GOOD
PORTION OF THE DAY MONDAY. ATMOSPHERIC PARAMETERS LIKE INTEGRATED
WATER VAPOR TRANSPORT (IVT), PRECIPITABLE WATER (PWAT), WARM CLOUD
LAYER TO AROUND 14K FT, AND MID-LEVEL WINDS ONLY UP TO AROUND 20-25
KT ARE FAVORABLE INGREDIENTS OF HEAVY RAINFALL WITH LOCALIZED
IMPACTS BEING A CONCERN. PWATS PEAK MONDAY MORNING AROUND 2.25
INCHES WHICH IS VERY IMPRESSIVE. ALSO A SLOW MOVING FRONTAL BOUNDARY
TO THE WEST IS ANOTHER INGREDIENT ADDING TO THE HEAVY RAIN
POTENTIAL. WPC MAINTAINS A SLIGHT RISK OF EXCESSIVE RAINFALL ON
MONDAY, WITH A MARGINAL RISK ON THE FRONT END DURING SUNDAY EVENING
/ NIGHT. PRECISE TIMING OF THE PERIOD OF HEAVY RAINFALL, AND WHERE
THE RELATIVELY HIGHER RAINFALL TOTALS WILL OCCUR REMAINS UNCERTAIN
AT THIS TIME. IF CONFIDENCE IN THESE INCREASE, THEN A FLOOD WATCH
WILL BE CONSIDERED IN SUBSEQUENT FORECAST UPDATES.
KEY MESSAGE 3
WITH A WESTERN ATLANTIC RIDGE FORECAST TO RETROGRADE, THE FRONTAL
BOUNDARY THAT PUSHED THROUGH DURING MONDAY AND MONDAY NIGHT IS
FORECAST TO STALL JUST SOUTH OF THE AREA IS LIKELY TO PUSH BACK
NORTHWARD AND INTO THE AREA AGAIN DURING MID WEEK. THIS WOULD LIKELY
LEAD TO A PERIOD OF UNSETTLED CONDITIONS, ESPECIALLY DURING THE
AFTERNOON AND EVENING HOURS AS ANY BOUNDARY ACROSS THE AREA WOULD
LIKELY TRIGGER SCATTERED SHOWERS AND THUNDERSTORMS WITH A HUMID
AIR MASS IN PLACE.
AVIATION /00Z SUNDAY THROUGH THURSDAY/
HIGH PRESSURE CONTINUES TO WEAKEN TONIGHT. A WARM FRONT STARTS
TO MOVE THROUGH SUNDAY EVENING.
LOW CONFIDENCE OF MVFR/IFR CONDITIONS RETURNING TONIGHT, MAINLY
FOR KGON. THEN, MAINLY VFR THROUGH SUNDAY AFTERNOON. MVFR
BEGINS TO BECOME POSSIBLE FOR MOST TERMINALS AFTER 21Z SUNDAY
WITH PERHAPS ISOLATED -SHRA. MVFR THEN LIKELY STARTING LATE
SUNDAY EVENING.
A FEW GUSTS UP TO AROUND 20 KT ARE POSSIBLE THIS EVENING. S/SSE
FLOW CONTINUES OVERNIGHT JUST UNDER 10 KT. S/SSE THEN THROUGH
SUNDAY WITH GUSTS AROUND 20-25KT DURING THE LATE MORNING AND
EARLY AFTERNOON.
...NY METRO (KEWR/KLGA/KJFK/KTEB) TAF UNCERTAINTY...
OCCASIONAL 20 KT GUSTS POSSIBLE EARLY THIS EVENING.
AMD MAY BE NEEDED SUNDAY AFTERNOON/EVENING FOR START TIME OF
MVFR/-SHRA.
OUTLOOK FOR 00Z MONDAY THROUGH THURSDAY
SUNDAY NIGHT: MVFR OR LOWER IN -SHRA BECOMING IFR IN SHRA AND
POTENTIAL THUNDERSTORMS LATE.
MONDAY-THURSDAY: SUB-VFR IN SHOWERS AND THUNDERSTORMS. S WINDS
G20KT MONDAY.

SUB ADVISORY CONDITIONS PREVAIL ON THE WATERS THROUGH THE FIRST HALF
OF SUNDAY NIGHT. SMALL CRAFT CONDITIONS BECOME INCREASINGLY LIKELY

NIGHT INTO MONDAY AS A SOUTH WIND PICKS UP AND SEAS BUILD. SMALL
CRAFT CONDITIONS WILL LIKELY CONTINUE FOR THE OCEAN THROUGH
MONDAY NIGHT AS THE WINDS VEER MORE TO THE SW AND SEAS REMAINING
ELEVATED AROUND 5 TO 6 7 FT. SUB ADVISORY CONDITIONS SHOULD

SUBSIDING CLOSER TO 3 TO 4 FT.
