&&

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Coastal Flood Advisory indicates that onshore winds and tides
will combine to generate flooding of low areas along the shore.

There is a high risk of rip currents.

Rip currents are powerful channels of water flowing quickly away
from shore, which occur most often at low spots or breaks in the
sandbar and in the vicinity of structures such as groins, jetties
and piers. Heed the advice of lifeguards, beach patrol flags and
signs.

Swim near a lifeguard. 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.

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.

NWS Miami, FL wrote its last area forecast discussion before this high surf advisory went out at Sep 20, 1:38 AM EDT, 2 hours 20 minutes earlier.

Area forecast discussion, Sep 20, 1:38 AM EDT, 2 hours 20 minutes before
Area Forecast Discussion
National Weather Service Miami FL
138 AM EDT Sun Sep 20 2020

.Aviation...
Rain and storm chances will increase through the day as a frontal
boundary approaches the area. Morning wind flow will shift from
west-northwesterly to just east of north through the morning with
NE gusts picking up in the afternoon along with convection. Sub-
VFR conditions possible with convection which could linger into
the overnight along with increasing NE winds and wind gusts.

&&

.Prev Discussion... /issued 319 PM EDT Sat Sep 19 2020/

Short Term (Now through Sunday)...
A ridge of high pressure remains intact over South Florida, limiting
steering flow (850-300 hPa mean wind < 5 kts) and inducing
subsidence across the region. The weak synoptic flow and lack of
cloud cover over land should allow for typical sea-breeze
development today, along both the Atlantic and Gulf coastlines. With
the absence of any larger scale forcing, sea-breezes and outflow
boundaries will act as the main triggering mechanisms for any
showers/storms that do develop today.

A light SSW surface wind along the southern portion of the forecast
region backs a bit towards the E/NE along the Atlantic coastline.
This should pin the Atlantic sea-breeze along the Atlantic
coastline, favoring shower/storm development across portions of the
metro region. While the environment in not favorable for strong
convection today (owing to modest subsidence and paltry shear
values), a swath of higher precipitable water indices is likely to
develop along most of the Atlantic metros this afternoon. Given the
aforementioned weaker steering flow, localized flooding is the main
threat, where storms develop along the sea-breeze and meander and/or
backbuild. Higher wind gusts are possible if storms are able to
develop within a favorable mesoscale environment.

By Sunday, the tail end of a frontal boundary progresses southward
across South-Central Florida. Pressure gradient will tighten in
association with this approaching front, resulting in an uptick in
wind speeds. The highest speeds are forecast to occur over the Palm
Beach waters, but may extend further south into Broward/Miami-Dade
waters further into the period. Additionally, a noticeable 500
hPa impulse is forecast to transverse the region. A low-level
convergent signal is apparent in the boundary layer winds, and a
swath of higher moisture congeals in association with this
lingering boundary. This will support enhanced storm chances for
Sunday, especially in the afternoon. This is reflected in the
current forecast, as PoPs for most of the region are the in the
60-80 range during this timeframe. Localized flooding could become
a concern to monitor, especially within areas that received high
antecedent rainfall totals.

Temperatures will feel seasonably warm, with upper 80s/lower 90s
across the region, with a slightly decreasing trend Sunday. With
that said, the front will not bring much relief, as any temperature
limitations will be primarily due to widespread cloud cover and/or
rainfall.

Long Term (Sunday Night through Saturday)...
The latest computer model guidance continues to show the frontal
boundary pushing southeastward across the region on Sunday night
into Monday. Out ahead of the frontal boundary, deep moisture will
remain in place which will allow for increased chances of showers
and thunderstorms to continue during this time frame. Periods of
heavy downpours could lead to the potential of localized flooding
throughout the day on Monday in the urban and low lying areas.
This front will be pushed south of the region and into the Florida
Straits on Monday night. The combination of a strong area of high
pressure to the north and Hurricane Teddy interacting with an
amplifying shortwave trough well off to the northeast in the
Atlantic will allow for the pressure gradient across the region
to tighten even further on Tuesday.

Both of the GFS and the ECMWF show a drier air mass moving into
South Florida on Tuesday as high pressure builds in from the
north. With the tightening pressure gradient, the winds will
increase across the region out of the northeast and breezy
conditions will persist. Chances of showers will be on the low
side through the middle of the week as the dry air mass remains in
place. Any shower that does develop during this time frame will be
shallow and fast moving. High temperatures through the middle of
the week will generally range from the mid to upper 80s across the
east coast metro areas to around 90 across the interior sections.

By the end of the week, the latest GFS and ECMWF show the frontal
boundary over the Florida Straits slowly moving back northward as
a warm front. This will advect more moisture back into the region
and it will cause the winds to shift to more of a southeasterly
direction and then eventually more southerly. With the increase in
moisture, the chances of showers and thunderstorms will once again
increase during this time frame. There still remains a great deal
of uncertainty during this time as Tropical Storm Beta could also
be an influential factor with the frontal boundary speed and
movement. With the increased amount of moisture in the region,
locally heavy rainfall could create another potential for
localized flooding during this time frame. This will continue to
be monitored as the week progresses.

Marine...
The tail end of a frontal boundary will linger over south-central
Florida. While not of major concern today, wind speeds will increase
tomorrow ahead of the front, mainly out of the NE. A surge of
moisture will advance ahead of the front tomorrow as well, which
will increase the chance for showers and storms across the region.
Breezy NE winds in association with the front combine with swell
emanating from Hurricane Teddy to produce hazardous seas beginning
Sunday afternoon. The highest swell and wave heights are forecast to
be over the Palm beach waters, but may protrude southward into
Broward/Palm Beach waters as well. Given the aforementioned
conditions, a Small Craft Advisory is currently in effect. There
could be periods where wind speeds meet gale force criteria, however
this does not currently merit a Gale Watch. Will monitor and update
as necessary.

Beach Forecast...
NE swell off the Palm Beach coast will allow an elevated risk of rip
currents to persist through the weekend, with the highest risk along
the Palm Beach coastline. Easterly swell through the Providence
channel will arrive during the weekend with northerly swell from the
Atlantic joining in later in the weekend into early next week. This
could lead to the elevated risk of rip currents spreading southward
along the Atlantic coast of South Florida and lingering well into
next week.

Astronomically higher than normal tides may result in minor coastal
flooding along coastal Miami-Dade, Broward, and Palm Beach counties
and isolated minor coastal flooding in Collier County through Sunday
evening. Considering this risk, a Coastal Flood Statement is in
effect for the Atlantic coast.

...Isolated Thunderstorms Possible This Evening...
...Elevated Rip Current Risk for Atlantic Beaches...
...Minor Coastal Flooding Expected During High Tides...

This hazardous weather outlook is for South Florida.

.DAY ONE...TONIGHT

Rip currents: A high risk of rip currents exists for the Palm
Beaches. A moderate risk of rip currents exists for the Atlantic
beaches of Miami-Dade and Broward through the evening.

Coastal Flooding: Minor flooding of coastal locations is possible,
particularly around the times of high tide due to astronomically
higher tides.

Thunderstorms:  A few thunderstorms are possible across South Florida
this afternoon and evening. Lightning and locally heavy rainfall are
the primary hazards.

Waterspouts: A few waterspouts are possible today for all the local
South Florida waters.

Waves: Incoming swell tonight will allow seas in the Atlantic to
build to 5 to 7 feet with occasional seas to 9 feet in the
Gulfstream, mainly over the Palm Beach coastal waters. Small Craft
Advisories are in effect for the Atlantic waters starting tonight.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY

Minor coastal flooding is expected during high tide cycles through
the weekend.

Abundant moisture will remain over the area through much of the
weekend and next week, keeping the risk of flooding, especially for
urban and low-lying areas.

A frontal boundary is expected to approach the region late this
weekend, increasing rain and thunderstorm chances across South
Florida. Breezy northeasterly winds are projected behind the frontal
passage, leading to hazardous marine and beach conditions through
early next week.

.SPOTTER INFORMATION STATEMENT...

Widespread spotter activation is not anticipated, however individual
spotters are encouraged to report high wind, funnel clouds,
waterspouts, and flooding to the National Weather Service forecast
office in Miami. Please relay any information about observed severe
weather to the NWS while following all local, state, and CDC
guidelines.
