What forecasters said that day
The local office's own words before this high surf advisory went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

Area forecast discussion, Sep 16, 2:03 PM EDT, 51 minutes before
Area Forecast Discussion
National Weather Service Taunton MA
203 PM EDT Sat Sep 16 2017
.SYNOPSIS...
Mainly dry and warm/humid weather is expected this weekend, but
a few isolated showers or a thunderstorm can not be ruled out
both days. Hurricane Jose will bring high surf and dangerous rip
currents this weekend into the middle of next week. Wind and
rain effects are possible, especially across Cape Cod and the
Islands. But the full extent of those impacts and their timing
remains dependent on the uncertain storm track. High pressure
then builds over the region with drier and seasonable weather
Thursday and Friday.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
2 PM update...
Stratus and fog has eroded for the most part with sct-bkn cu
developing, but low clouds still lingering across portions of
Cape Cod. There may be a short window for partial clearing on
the Cape before clouds fill back in by late afternoon.
Scattered showers have developed across SE NY within instability
axis of SBCAPES 1000+ J/kg. Higher instability extends east into
western MA and northern CT so still can't rule out a few showers
or an isold t-storm in this region. Given weak wind fields and
high PWATs, there is a low risk for locally heavy rainfall.
Highs should reach upper 70s to lower 80s. Sea breezes will
keep it cooler along the immediate coast. Humid airmass with
dewpoints in the mid/upper 60s.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SUNDAY/...
Tonight...
Any leftover showers across N CT/W RI will dissipate by 02Z,
otherwise expect dry conditions. Otherwise, expect mainly dry
conditions. However, areas of fog and low clouds move into
coastal areas and will likely redevelop across the normally
prone inland valleys as dewpoints remain in the lower-mid 60s.
May need dense fog headlines again for some areas. Another humid
night with temps falling back to the upper 50s to lower 60s.
Sunday...
A near repeat of today as H5 W-E elongated short wave/vorticity
max lingers across N CT/RI into SE Mass as it remains parallel
to the upper flow. So, could see another shot for isolated
showers or even a thunderstorm during the afternoon across N CT
and W RI. Have kept POPs in the slight chance range. Temps will
again rise to the 70s to lower 80s.
&&
.LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/...
16/00Z guidance suite has come into better agreement with the
handling of Jose through Monday. The CMC remains the fastest and
farthest north, while the GFS and ECMWF are quite close. GFS
remains the model keeping Jose the strongest through Monday, but
still appears to be a bit too strong.
Beyond Monday, 00Z guidance suite seems to have latched onto
the idea of Jose eventually turning to the right, even in the
ensembles. The question which remains to be answered is: how
soon? That very important question is why there is low
confidence in the details of the forecast Monday night into
Wednesday. Southern New England still looking at the possibility
of a landfalling tropical cyclone, to a near miss southeast of
Nantucket.
Moderate confidence in the forecast for the end of next week.
Once Jose moves away from our region, we should see a high
pressure build south from eastern Canada.
Near to slightly below normal temperatures expected much of
next week.
&&
.AVIATION /18Z SATURDAY THROUGH THURSDAY/...
Forecaster Confidence Levels...
Low - less than 30 percent.
Moderate - 30 to 60 percent.
High - greater than 60 percent.
Short Term /through Sunday night/...
Through 00z...Mainly VFR, but areas of MVFR/IFR stratus
lingering on Cape Cod. Stratus and fog lurking over the waters
may expand across the islands toward 00z.
Tonight through Sunday night...High confidence in trends. Lower
confidence in timing. Expect stratus and fog to redevelop
across much of SNE tonight with IFR/LIFR conditions. Improving
conditions to VFR by late Sunday morning or early afternoon,
then lowering back to IFR/LIFR Sunday night. Light winds with
weak coastal sea breezes.
KBOS Terminal...High confidence in trends. Lower confidence in
timing. IFR/LIFR stratus and fog likely redevelops tonight.
KBDL Terminal...High confidence in trends. Lower confidence in
timing. IFR conditions likely redevelop tonight.
Outlook /Monday through Wednesday/...
Monday...High confidence.
VFR. Patchy MVFR/IFR in fog and low clouds early Monday
morning. Chance of MVFR cigs in widely scattered showers Monday
afternoon. MVFR cigs/vsbys may reach the south coast Monday
night, depending on the track and speed of Hurricane Jose.
Tuesday-Wednesday...Low confidence.
MVFR with areas of IFR in low clouds/rain/fog. Potential for NE
winds at 35-40 kt. Poor visibility on Cape and Islands in rain
and fog. Conditions are dependent on the track and speed of
Hurricane Jose. Some improvement possible from west to east
Wednesday afternoon.
&&
.MARINE...
Forecaster Confidence Levels...
Low - less than 30 percent.
Moderate - 30 to 60 percent.
High - greater than 60 percent.
Short Term /through Sunday/...
Through Today...High confidence.
Expect light winds with seas 4 ft or less. Areas of low clouds
and dense fog across most of the coastal waters with visibility
at or below 1/2 mile. Conditions may slowly improve by around
12Z-14Z across the near shore waters, with reduced visibility
continuing across the open waters.
Tonight and Sunday...Moderate confidence.
Expect light southerly winds. Visibility will again lower to
1/2 mile or less across the open waters in areas of low clouds
and fog, which will move into the near shore waters tonight
into early Sunday.
As Jose moves north, swells will push across the southern
waters. Expect seas to build to 3-6 feet, highest on the
southern outer waters. Have put up small craft advisories for
hazardous seas, which could reach into Block Island and RI
sounds by Sunday morning.
Outlook /Sunday Night through Wednesday/...
Expecting to have marine headlines during much of this period,
especially across the southern coastal waters.
Seas expected to slowly build Sunday night into Monday night.
Winds and seas should then build faster Tuesday into Tuesday
night. High seas will linger into Wednesday, but will start to
subside once Hurricane Jose moves off. Much of the high seas are
focused along the South coasts of RI and MA, but then spread to
the east coast of Cape Cod Tuesday.
Much of this depends on the track of Jose, which has plenty of
time to change over the next several days. Mariners are strongly
urged to monitor the latest forecasts regarding Jose this
weekend into early next week.
&&
.TIDES/COASTAL FLOODING...
Jose's large wind envelope will likely produce significant seas
with a large swell component; moving onshore early to mid next
week. Significant wave action should occur on top of relatively
high astronomical high tides and a building surge. As a result,
we believe there is a high risk of moderate to severe beach
erosion over a prolonged period early next week. Multiple high
tide cycles of large swells breaking onshore have us concerned
that we could experience a very serious beach erosion event
along portions of both our south and east facing ocean- exposed
shorelines next week.
In addition and dependent upon how close Jose gets to our
coast, there is also a risk for minor to moderate coastal
flooding along portions of the coast with probably southeast and
east facing shorelines most at risk.
&&
.BOX WATCHES/WARNINGS/ADVISORIES...
CT...None.
MA...None.
RI...None.
MARINE...Small Craft Advisory for hazardous seas from 6 PM this evening
to 6 PM EDT Sunday for ANZ254>256.
Small Craft Advisory for hazardous seas from midnight tonight
to 6 PM EDT Sunday for ANZ235-237.

No hazardous weather is expected at this time. .DAYS TWO THROUGH SEVEN...Sunday through Friday. Hurricane Jose will likely bring high surf and dangerous rip currents to some ocean-exposed beaches later this weekend into the middle of next week. There is the potential for significant erosion along ocean-exposed beaches early to mid next week. There is also a risk for minor to moderate coastal flooding if Jose passes close enough to southern New England. It remains uncertain if Jose will get close enough to southern New England for any other impacts during the first half of next week. There is a possibility of tropical storm force winds reaching portions of Rhode Island and southeast Massachusetts, with the Cape and Islands most at risk. If this should happen, then scattered power outages would be possible given full foliage at this time of year. There could also be pockets of heavy rain. We need to stress that there remains considerable uncertainty in how close Jose will get to our region. People in southern New England are urged to monitor the latest forecasts through this weekend. .SPOTTER INFORMATION STATEMENT... Spotter activation is not expected at this time.
