AMZ600 Synopsis For Jupiter Inlet To Ocean Reef Fl Out To 60 Nm And For East Cape Sable To Bonita Beach Fl Out To 60 Nm- 420 Pm Edt Wed Aug 21 2019
Synopsis.. Easterly to southeasterly winds will prevail throughout the rest of the week. Showers and Thunderstorms will be possible each day and night over the local south florida waters. Increased moisture from a disturbance moving in from the bahamas on Friday into the weekend will bring elevated precipitation chances. Gusty and erratic winds with locally higher seas are possible in and around any Thunderstorms. Overnight easterly wind surges could bring gusty winds near cautionary criteria.
Gulf stream hazards..Lightning, gusty winds, locally higher seas, and waterspouts are possible with showers and Thunderstorms over the gulf stream. The approximate location of the west wall of the gulf stream as of aug 20, 2019 at 1200 utc... 5 nautical miles northeast of fowey rocks. 8 nautical miles east northeast of port everglades. 8 nautical miles east of lake worth. 12 nautical miles east northeast of jupiter inlet.

Update
Isolated rain showers and thunderstorms continue to develop over
the offshore atlantic waters this evening, progressing westward
with the mean steering flow, and dissipating as they approach the
atlantic nearshore waters. A convergence boundary remains evident
over the gulf waters, where thunderstorm activity has been steady
over the past several hours. Forecast remains on track, with
additional shower and thunderstorm development expected over the
atlantic waters overnight. Short range hi-res guidance continues
to bring some of these showers and storms into the east coast
metro during the early morning hours.

Prev discussion issued 813 pm edt Wed aug 21 2019
aviation...

drier conditions expected over the few hours as lingering
convection near kapf and light shra over the atlantic dissipate.

Moisture increases across the region tomorrow should allow the
chance of shra and TS to increase at all TAF sites. Easterly flow
will help push initiating storms towards the interior between
16-23z as both sea breezes develop. Temporary reductions in vis
and CIGS possible with passing storms. Otherwise, prevailingVFR
conditions expected at all terminals.

discussion...

rest of today and tonight: rain showers and thunderstorms have begun
to develop over the interior and lake okeechobee region this
afternoon and are progressing westward with the mean easterly to
southeasterly flow towards the gulf coast. Isolated to scattered
convection has also been developing over the offshore atlantic
waters, moving westward with the mean wind flow as well. The
greatest storm coverage for the remainder of the day is expected
over the gulf coast and adjacent waters. The main threat with these
storms with be locally gusty winds and frequent lightning.

Easterly to southeasterly steering flow will allow for the further
development of isolated showers and thunderstorms over the
offshore atlantic waters during the overnight hours. Some of these
isolated showers and storms may move onshore into the east coast
metros during the early morning hours, then continue westward
towards the interior during the morning hours. Some of the high
resolution guidance has struggled with this trend over recent
days.

Thursday: once again, atlantic high pressure remains the dominant
synoptic feature for S florida, leading to persistent easterly to
southeasterly flow throughout the day. Sufficient moisture should
be available across S florida, allowing for greater convective
coverage during the early afternoon than previous days for all of
s florida. One can expect the greatest storm coverage to be
focused in the interior and gulf coast with the development of a
gulf sea breeze.

Friday into the weekend: an area of scattered convection is
currently east of the bahamas and expected to progress westward into
s florida late this week into the weekend. This will provide a
moisture feed into the peninsula that will increase overall storm
coverage and heavy rainfall potential through the weekend. In
addition, the mean steering flow will become more southerly as an
area of enhanced convection progressing into the region from the
bahamas creeps into the area. This will allow for the development
of both east and west coast sea breezes, further enhancing
convective coverage over the weekend. The national hurricane
center has this feature highlighted in their tropical weather
outlook (twoat) with a low chance of further development in the
next 5 days.

Early next week: high pressure in the gulf will build into s
florida, leading to light southerly to southwesterly winds. With
this pattern, expect the development of both the atlantic and
gulf sea breezes to drive convection throughout the afternoon each
day. Main focus for convection during this period will be in the
interior.

Marine...

easterly to southeasterly flow will prevail through the week with
nocturnal easterly wind surges, mainly over the atlantic, that could
bring conditions near scec. Showers and thunderstorms will be
possible each day and night over the local south florida waters.

Gusty and erratic winds with locally higher seas are possible in and
around any convection. A tropical disturbance over the bahamas will
need to be monitored for any potential impacts to the waters. Nhc
currently gives the feature a low chance of further development over
the next 5 days.

Beach forecast...

the persistent easterly to southeasterly flow through a good portion
of the week will allow an elevated risk of rip currents to continue
along the atlantic beaches of south florida through at least the
weekend. Eyes continue on the disturbance over the bahamas and any
potential impact it may present for the atlantic waters.

Hydrology...

with a few periods of heavy rainfall possible late this week into
the weekend as an area of disturbed weather over the bahamas and
associated moisture push across the region, the potential for ground
saturation leading to an increased risk of flooding remains. The
west coast metro is an area that will require some monitoring as the
easterlies will restrict the progress of the gulf sea breeze which
will allow a convective focus to hang around the naples area until
the pattern shifts. Cannot rule out any part of south florida for
minor flooding concerns due to the potential for heavy rainfall with
this disturbance.

Fisheating creek at palmdale has a current stage of 6.28, which
places it on action stage below the flood stage of 7 feet. The
forecast continues to call for the creek to remain below flood stage
but any heavy rains in the basin over the coming days could cause
some changes in the forecast. We will still need to monitor in case
excessive rainfall above forecast occurs upstream in the basin over
portions of glades and highlands counties, leading to rapid rises
in the creek above flood stage.
