Marine Weather and Tides
Hallandale Beach, FL

Version 3.4
What's New / NOTES
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.

Aviation
Latest radar imagery shows most of the shra activity concentrated
over the interior moving nw. A few shra will be possible near the
east coast terminals before they gradually progress west away from
most of the terminals after 15z. The only exception will be pbi,
where more shra will be expected near the area a little longer.

For the west coast, the chances of rain increase into the afternoon.

Vfr prevail through much of the period with the exception of a few
MVFR CIGS due to any thunderstorm near the area with gusty winds.

discussion...

short term (today through Wednesday night)
a few changes are in store for south florida in spite of this
relatively stagnant wet pattern of the past week, but Monday will
still be a wet day across the region. Overnight, several waves of
showers, some with very heavy downpours, have moved inland into
the miami-fort lauderdale-west palm beach metropolitan area,
dropped over an inch of rain in some locations and prompting
another broward county flood advisory. That advisory has expired
but the flood watch will remain in effect until noon for metro
fort lauderdale, as any additional rainfall will likely lead to
quick ponding and at least some flooding. Mesoscale convective
models are not overly enthused about today's heavy rain chances,
and wpc has lowered rainfall amount forecasts through the next
several days. Still, expect numerous showers, some with locally
heavy rainfall, as well as isolated thunderstorms. Despite a
continued plume of deep tropical moisture from the caribbean
overhead, the influence of the subtropical ridge to the east is
nosing its way toward the east coast of florida. This should at
least focus the precipitation more toward the gulf coast, though
scattered activity will likely prevail areawide through midweek.

Abundant cloud-cover will continue to curb diurnal warming, but
maxima should be able to creep closer to normal by mid-week. See
hydrology section below for details on the week's heavy rain flood
potential.

Long term (Thursday through Sunday)
the mid upper level trough over the central and eastern gulf of
mexico will re-establish itself as the atlantic high pressure
weakens for late in the week. The forecast for this period holds
quite a bit of uncertainty as 1) ECMWF and GFS continue to offer
contrasting solutions (ecmwf has stronger and longer lasting
ridging, holding off significant moisture return until closer to
the weekend, GFS brings major moisture back in by Thursday) and 2)
both models suggest the re-strengthened trough in the gulf may
pull a sort of disturbance from the caribbean sea into the gulf
by the end of the week, but the timing, location, and strength of
the disturbance holds little model agreement at this time.

Regardless of which model is right, it appears rain chances will
be on the increase again by Friday at the latest, and unless a
fast, northeastward moving disturbance can clear the area and
bring drier air in behind in by the middle of the holiday weekend,
it appears showers will remain likely throughout, with a potential
for renewed heavy rainfall.

Marine...

southeast wind of 15 to 20 knots will continue perhaps as last as
Tuesday, nearing 20 knots sustained at times over atlantic waters.

At this time, no advisory will be issued, but conditions will be
closely monitored over the next 36 hours or so. Thereafter, wind
should remain southeast but diminish to 10 to 15 knots through
late week. Seas will build to around 5 feet in atlantic waters
today and Tuesday, before returning to levels similar to gulf
waters, 2 to 4 feet.

Aviation...

showers with MVFR and brief ifr conditions wind gusts 25 knots
concentrating primarily pbi fll area through 08z-10z, then
becoming more scattered in coverage from 12z onward along the east
coast pbi-mia. By 17z, most of the precipitation will likely be
over the interior and gulf coast. At kapf, sct to perhaps bkn
below 1,000 ft before 14z, then prob30 for tsra after 18z. Wind
120-130 degrees 8-12 knots, increasing to 15g22 knots after about
15z.

Beach forecast...

persistent southeast winds of 15 to 20 mph will lead to a high
risk of rip currents on atlantic waters through Tuesday. This
could continue into Wednesday, with as least some enhanced risk of
rip currents likely continuing through the week.

Hydrology...

rainfall amounts averaging 4 to 7 inches across the east coast
metropolitan areas Saturday has erased any remaining rainfall
deficits. The good news regarding flooding in the next few days,
is that after this morning, additional rainfall amounts through
Wednesday are likely to average 1 to 2 inches, and be focused more
on the relatively drier grounds of southwest florida. Still,
locally higher amounts are possible, particularly today, and with
grounds saturated, especially in broward county, additional
flooding cant be ruled out.

Guidance continues to suggest a relatively lull (or more of a
return to normal rainy season) Tuesday and Wednesday (possibly
continuing into Thursday) before deep tropical moisture and the
threat for heavy rain returns ahead of the start to the holiday
weekend.
