Aviation Prevailing SW flow in place across south florida now
that TD three has moved NE of the area. Moist environment will
promote scattered shra tsra development by late morn continuing
through early eve. Convection will focus in the pbi-fll corridor
18z- 00z. Convection cannot be ruled out at any terminal however,
though chances are much lower at kapf to preclude even vcts vcsh
mention. Brief bouts of sub-vfr are possible with convection,
particularly ifr lifr in heavy rain.

Moderate risk of rip currents palm beach county beaches today...

Scattered to numerous storms interior eastern areas through the week...

discussion...

tropical depression 3 located over the northern portion of south
florida waters is forecast by NHC to continue to move northward
into central florida atlantic waters today, as a cold front over
the southeastern united states moves southward towards northern
florida. This will allow for the steering flow to be
south southwest over south florida bringing in deep tropical
moisture to the area. This will lead to scattered to numerous
showers and thunderstorms over the interior and east coast metro
areas this afternoon with the best coverage over the northeast
areas. The west coast metro areas will also see some showers and
thunderstorms mainly in the morning hours.

The through of low pressure will stall over northern florida on
Wednesday and slowly dissipate through rest of the week,as
tropical depression 3 is forecast by NHC to move northeast and
dissipate over the western atlantic waters. This weather pattern
will allow for the steering flow to remain in a south southwest
direction over south florida focusing the highest pops over the
interior and east coast metro areas each day through rest of the
week.

Highs rest of this week will be in the lower to mid 90s over most
of south florida, except for upper 80s to lower 90s over the west
coast metro areas. Lows will also remain in the 70s over south
florida during this time frame.

Extended forecast...

high pressure will build back into the florida peninsula this
upcoming weekend from the western atlantic waters allowing for the
easterly wind flow to set up over south florida. This will allow
for late night and morning showers and thunderstorms over the east
coast metro shifting to the interior and west coast metro areas in
the afternoon and evening hours for the weekend.

Marine...

the winds will be mainly be south to southwest at 10 knots or
less over most of south florida waters today through rest of the
week. The only exception is over the offshore atlantic waters of
palm beach county where the speeds will be 15 to 20 knots this
morning decreasing to 10 to 15 knots this afternoon, as tropical
depression 3 moves northward away from south florida. This will
allow for the seas to be 2 feet or less over most of the local
waters, except for the atlantic waters of palm beach county where
they will be 2 to 3 feet today. Therefore, the SCA will continue
for the offshore atlantic waters of palm beach county until
around 8 am edt this morning before going to scec conditions for
today. The near-shore atlantic waters of palm beach county will
also be in scec conditions until 8 am edt this morning.

Beach forecast...

the threat of moderate risk of rip currents will also continue
along the beaches of palm beach county today, while rest of the
east coast beaches and west coast beaches of south florida will be
in the low risk of rip currents.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
