Marine Weather and Tides
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

436 pm edt Sun may 20 2018
This afternoon and tonight: the weak upper level low and associated
low level trough that have been driving our weather the past few
days have moved off into the northeastern gulf of mexico this
afternoon. This has shifted the deepest portion of the moisture
plume and low level convergence off to our west as well.
As a result, the significant heavy rain threat has ended for now
across much of the region this afternoon, though light to moderate
showers will continue into the evening.
Overnight, models are hinting at another pocket of higher
moisture enhanced low level winds sliding into the east coast again
late tonight early Monday morning. Current solutions are not as
bullish with amounts as this morning, likely to due to the lack of
upper level support. The fate of the ongoing flood watch in broward
county is a tough call because of this. Given this morning's
rainfall and ongoing flooding concerns, even an additional inch will
aggravate ongoing problems. Will hold the watch as is for now, and
re-evaluate as more short range guidance comes in this evening.
Monday through Wednesday: the florida peninsula will remain in
between the western atlantic ridge to our east and a broad upper
level trough to our northwest across the north gulf through most of
the upcoming week. Ongoing south-southeasterly flow in both the low
and mid levels in between these two features will continue to pump
modest tropical moisture across the region, with pwat values
expected to remain just above seasonal norms through the period.
Steering flow will favor a pattern of overnight morning coverage
along the east coast and atlantic with afternoon showers and storms
mainly across the interior and gulf coast. While rain chances remain
above normal, we should see a shift to more of a diurnal maximum in
coverage by Tuesday. Threat for locally heavy rainfall will linger
into Monday, with just enough drier air edging in on Tuesday that it
will likely be the "driest" day of the week with coverage
remaining more scattered.
Mid and upper level clouds will continue to limit sunshine, which in
turn will keep overall instability and storm coverage down as well
as daytime temperatures. High temperatures will struggle to get into
the 80s on Monday. Less rainfall will allow highs in the mid 80s
Tuesday and Wednesday.
Thursday into next weekend: the forecast as we end the week and head
into next weekend remains very uncertain as global models continue
to diverge in solutions. Both agree on the basic synoptic evolution,
with the atlantic ridge breaking down as the persistent upper level
trough across the gulf of mexico digs further south, allowing some
type of tropical disturbance to lift north out of the central
As always, the crux of the forecast is in the details. Where the
ecmwf keeps a stronger longer lasting subtropical ridge influence,
leading to drier conditions, with rain chances increasing Friday
night into the weekend as the forecasted tropical disturbance moves
toward the central gulf. The GFS however, keeps the ridge relatively
weaker, which allows for a faster moving disturbance in a more
northeasterly direction, though strength-wise it appears to be
suffering from some convective feedback.
For now, not too many changes with the ongoing forecast with rain
chances increasing once again late week. The potential for a return
to heavy rainfall will have to be watched.
Marine Southeast winds 15 to 20 knots will continue into Monday,
with winds approaching at steady 20 knots at times over the atlantic
waters. For now, will keep cautionary statement in place as any
advisory level conditions do not look to be widespread long lived.|
Seas 3-5ft in the atlantic and 2-4ft in the offshore gulf. Winds and
seas are expected to ease late Tuesday, with southeast winds 10-
15kts into the middle of the week.
Widespread showers with some thunderstorms will persist through
Monday, with the focus gradually shifting from the atlantic into the
gulf (and continuing for lake okeechobee). The heavier activity
could produce hazardous winds, locally higher waves, and dangerous
lightning. Coverage is expected to be a little more scattered
Aviation MVFR toVFR conditions prevail through the day as
showers and thunderstorms redevelop over the fl peninsula. A few
shra will produce brief periods of light to moderate rain along the
east coast terminals while a few TS could form over the west coast.
Most of the convection will be mostly focused over the west for the
afternoon keeping MVFR to possible ifr at times, especially apf
terminal. Expect a prevailing southeast flow through much of the
period with bkn to ovc skies. A few gusts up to 20 knots possible by
the end of the period into mid day Monday.
Beach forecast Southeast winds of 15 to 20 mph have lead to
numerous rip currents being reported at east coast beaches this
afternoon. A high risk of rip currents is now in effect for all
atlantic beaches through Monday. The enhanced risk may linger into
Tuesday before winds and seas subside.
Hydrology Morning rainfall brought a wide swath of 3 to 7 inch
rainfall totals across all of metro broward and the western side of
the palm beach metro this morning, as well as far north miami-dade
county. Several locations across broward topped out above 8 inches,
and wouldn't be surprised if a few spots reached 9-10 inches. This
all fell in about 6 hours, which in addition to the past few days
of heavy rainfall, lead to widespread significant street flooding
across these areas.
The heavy rainfall threat has diminished for the east coast and
interior for the moment, but some locally heavy rainfall will remain
possible along the gulf coast through this evening. There is some
concern for additional east coast rainfall overnight, though current
trends suggest amounts will not be as high as this morning.
However, any additional rainfall would aggravate ongoing flooding.
Additional heavy rain, averaging 1 to 2 inches, with locally higher
amounts, are possible Monday, before a relative lull is expected
into the middle of the week. Thereafter, will have to monitor for
additional heavy rain flood potential as deep tropical moisture is
poised to return.
