Atlantic Coastal Cape May-
135 PM EDT Sun Aug 22 2021

...HIGH RIP CURRENT RISK REMAINS IN EFFECT THROUGH MONDAY
EVENING...
...COASTAL FLOOD ADVISORY IN EFFECT FROM 7 PM THIS EVENING TO
MIDNIGHT EDT TONIGHT...

* WHAT...For the Coastal Flood Advisory, up to one half foot of
  inundation above ground level expected in low-lying areas near 
  shorelines and tidal waterways. For the High Rip Current Risk, 
  dangerous rip currents.

* WHERE...Atlantic Coastal Cape May.

* WHEN...For the Coastal Flood Advisory, from 7 PM this evening 
  to midnight EDT tonight. For the High Rip Current Risk, 
  through Monday evening.

* IMPACTS...Flooding of lots, parks, and roads with only 
  isolated road closures expected. Rip currents can sweep even 
  the best swimmers away from shore into deeper water.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Coastal Flood Advisory means that minor tidal flooding is
expected. Minor tidal flooding often results in some road
closures. Usually, the most vulnerable roadways will flood. 

Do not leave your vehicle at a location that is prone to tidal
flooding. Do not drive your vehicle through flood waters. The
water may be deeper than you think it is. You will be putting
yourself in danger and your vehicle may be damaged, leading to
costly repairs. 

Visit the Advanced Hydrologic Prediction Service at
water.weather.gov/ahps for additional water level and flood
impact information for your local tide gauge.

Entering the surf is discouraged. If caught in a rip current,
relax and float. Don't swim against the current. If able, swim in
a direction following the shoreline. If unable to escape, face
the shore and call or wave for help.

Area forecast discussion, Aug 22, 1:32 PM EDT, 3 minutes before
Area Forecast Discussion
National Weather Service Mount Holly NJ
132 PM EDT Sun Aug 22 2021

.SYNOPSIS...
Tropical Storm Henri will move northward into southern New
England today. The storm is forecast to weaken as it moves to
the northeast along the coast of Maine on Monday, reaching Nova
Scotia on Tuesday. High pressure is expected to build into our
region from the west and south for much of the new week. A cold
front from the north is anticipated to arrive on Thursday night
or Friday morning. Another area of high pressure is expected to
build from Quebec into New England on Friday and Saturday.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
**Tropical Storm Warnings for New Jersey Cancelled**

**Flooding Rain Threat Associated with Henri Continues**

11 AM...Tropical Storm Warnings for our New Jersey land and
ocean zones were cancelled with the 11 AM Advisory package as we
no longer expect these conditions for these zones. However the
heavy rain and flash flooding threat continues.

Tropical Storm Henri is currently located just east of Long
Island as of 11 AM. The heavy rain threat associated with the
system's western side is shifting mainly to the northern third
or so of our area for this afternoon and evening, as the
heaviest precipitation associated with Henri's circulation
pivots to the SW quadrant (where the best low- lvl convergence
and UL- divergence will be present). Amounts of 2-4 inches will
be possible particularly along and north of about I-78, with
amounts tapering off further south. However, with the mid-lvl
low (which will largely absorb Henri's mid-lvl circulation)
remaining overhead and abundant moisture, expect showery
precipitation to continue off and on over much of the area
through the day. We could even see some clearing and greater
destabilization over portions of Delmarva over the afternoon,
which may result in some stronger thunderstorms continuing in
this area. That being said given the lack of any appreciable
flow and still fairly tropical profiles (i.e. modest lapse
rates, limited dry air) think the severe threat is fairly low,
but can not rule out a few wet microbursts.

In terms of headlines...The Flood Watch remains in effect for
much of the area, to encompass both the lingering morning
threat and then the afternoon/evening threat over the North.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH MONDAY NIGHT/...
Whatever remains of Henri will move from New England to Nova
Scotia from Monday through Tuesday night. Very Warm and humid
high pressure is expected to build into our region from the west
and southwest in its wake.

Lingering showers with scattered thunder are forecast for
Monday. The last of the precipitation should move away to our
northeast on Monday night with no rain anticipated for Tuesday
and Tuesday night.

Highs are expected to be mainly in the 80s on Monday due to the
showers and cloud cover. Maximum temperatures should be near 90
in much of our region on Tuesday. Overnight lows will likely
favor the upper 60s and lower 70s.

&&

.LONG TERM /TUESDAY THROUGH SATURDAY/...
Bermuda high pressure is forecast to gain control over our
weather for Wednesday and Thursday. High temperatures are
forecast to be in the lower and middle 90s in much of our region
with dew point values in the lower and middle 70s. Heat index
values may approach or slightly exceed 100 in spots, especially
on Thursday, so we may eventually need a Heat Advisory for parts
of our area.

The high levels of heat and humidity, along with a cold front
approaching from the northwest and north, will result in a
chance of showers and thunderstorms for Thursday afternoon and
Thursday evening.

The cold front is anticipated to arrive from late Thursday
night into Friday morning. The boundary should move rather
slowly through our region, so there is another chance for
showers and thunderstorms on Friday afternoon and evening.

High pressure is expected to build from Quebec into New England
from Friday into Saturday. Temperatures and humidity levels
will begin to decrease at that time.

&&

.AVIATION /18Z SUNDAY THROUGH FRIDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY and surrounding areas.

Rest of Today...Periods of showers will continue to affect the
TAf sites through the rest of the afternoon. Conditions will
vary between VFR and MVFR at times. The showers may briefly
taper off from Wilmington-Philadelphia-Trenton southward late
this afternoon into this evening, with a possible improvement to
VFR for some locations, while a steadier rain continues for
portions of northeast Pennsylvania and northern New Jersey.
There will remain a slight chance of thunderstorms, but are not
included in the TAF due to low confidence.Winds will remain
mostly west to northwest 5-10 knots, with an occasional gust
around 15 knots. Moderate confidence in overall forecast, lower
confidence in flight categories.

Tonight...Steady rainfall across northeast Pennsylvania and
northern New Jersey will shift southward then eastward and
affect all TAF sites late this evening and overnight. As the
rain moves across the area, conditions will lower to MVFR, and
IFR for some locations. There will remain a slight
chance of thunderstorms, but are not included in the TAF due to
low confidence. Winds will shift to west to southwest
5-10 knots or less. Moderate confidence.

Monday...MVFR/IFR conditions will continue through the morning
hours as the steady rainfall becomes more showery in nature by
late morning. Conditions may improve to VFR as showers begin to
taper off through the afternoon. There will remain a slight
chance of thunderstorms, but are not included in the TAF due to
low confidence. Winds will be mostly southwest 5-10 knots, with
an occasional gust around 15 knots. Moderate confidence.

Monday night...VFR conditions are expected. West to northwest
winds 5 knots or less.

Outlook...

Tuesday...Mainly VFR. Northwest to west wind 5 to 10 knots.
Medium confidence.

Wednesday...Mainly VFR. Southwest to south wind 5 to 10 knots.
Medium confidence.

Thursday...Early morning low clouds and visibility restrictions
are possible, then VFR with a chance of afternoon and evening
showers and thunderstorms. Southwest wind 5 to 10 knots. Medium
confidence.

&&

.MARINE...
A Small Craft Advisory is in effect for the ocean waters, with
conditions forecast to remain below advisory levels on the
Delaware Bay. Expect wind gusts largely in the 20-30kt range
over most of the ocean waters, with seas initially around 6-8
ft, dropping to 4-6ft by this afternoon. Winds and Seas could
drop below SCA criteria tonight, but some lingering gusts will
be possible, particularly over the northern waters.

Outlook...

Monday...A steady fetch from the south may cause wave heights
to build near 5 feet on our ocean waters.

Tuesday through Thursday...No marine headlines are anticipated.

Rip Currents...

Long period southeasterly swells continue to increase on the
coastal waters of New Jersey and Delaware as Henri continues its
approach to southern New England. Thus there is a High Risk of
dangerous, life-threatening rip currents on Sunday. Entering the
surf zone is strongly discouraged this weekend.

Medium period southeasterly swells combined with elevated seas
is expected to result in a High Risk of rip currents is expected
again on Monday for much of the New Jersey beaches with a
moderate risk expected for the Delaware Beaches. Conditions
should generally improve into next week as the storm weakens and
moves into the Gulf of Maine.

&&

.HYDROLOGY...
Heavy rain will be a concern through at least tonight due to
the proximity of Henri and a midlevel low. Many risk factors for
heavy rain exist in our region including precipitable water
values well above normal, slow storm motions, and a deep warm-
cloud layer. Additionally, portions of the region have wet
antecedent conditions from recent heavy rains.

The second period of heavy rainfall this afternoon into tonight
will be focused mostly over the northern third or so of the
area (the Poconos and NW NJ). Farther south, heavy
showers/storms should become less widespread but due to how
much rain has fallen and the very moist environment additional
flooding/flash flooding will be possible in any heavier showers
that occur. A Flood Watch remains in effect for most of the
area through 12Z Monday, apart from southern Delmarva.

&&

.TIDES/COASTAL FLOODING...
Minor tidal flooding occurred along the coasts of New Jersey
and Delaware on Saturday evening in response to Hurricane Henri
passing to our east. Based on the expected track and speed of
the storm, the wind in our region should back around to the
northwest today. As a result, water will begin to get pushed
away from the coast. Only some lingering minor tidal flooding is
anticipated around the times of high tide today.

&&
