What's New / NOTES
6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported.
5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive.
5/19/2016 - There were issues with the 3 day airport observation history. I switched to another data source. Let me know if you see any issues with the data feeds.

Synopsis..Hurricane maria is forecast to lift north of the bahamas as it remains well east of florida late this weekend. This will bring a reinforcing northeasterly swell to the south florida atlantic waters, bringing hazardous seas starting late tonight into Sunday. The swell is expected to continue to move into the waters through at least the middle part of the upcoming week. Northeasterly flow of 10-15 knots will continue today, diminishing and becoming north to northwest late this weekend.
Gulf stream hazards..SEas up to 6 feet in a northeasterly swell today. Seas building 7 to 8 feet late tonight and Sunday in a long period swell of 12 to 14 seconds. The approximate location of the west wall of the gulf stream as of sep 21, 2017 at 1200 utc... 6 nautical miles east southeast of fowey rocks. 11 nautical miles east of port everglades. 5 nautical miles east northeast of lake worth. 8 nautical miles east northeast of jupiter inlet.

Morning showers will continue to develop through the day with
coverage of thunderstorms increasing this afternoon. Sea breezes
are expected to develop with a convective focus around boundary
collisions. Bouts of sub-vfr conditions with convection could
require short-fused amendments today.

discussion...

today through Sunday: large trough extending across the eastern us
is expected to develop into a weak upper level low that meanders
along the northern gulf coast through the remainder of the weekend.

Also in place will be a robust area of deep moisture across most of
the state. Pwats from last evening's mfl sounding were around 2.2",
with the potential for similar values today and tonight.

Temps aloft were seasonably cool from the sounding at around -6c,
but models show the potential for slight cooling to around -7c or so
today with the upper level feature at its closest point to the
region. While ene flow will dominate, there will once again be the
potential for a gulf breeze to develop near the coast.

Scattered showers and storms will likely develop late morning near
the east coast then spread inland through the afternoon. Steering
flow initially will be weak, with storms drifting sw, but
expected to pickup later in the day as hurricane maria lifts
northeast of the bahamas and the local pressure gradient tightens.

The concerns today will be for a few stronger storms given the
proximity of the upper low, especially along boundary collisions,
and heavy rainfall. Wpc has highlighted the eastern half of south
florida under a marginal risk for excessive rainfall, keying on
the potential for coastal convergence and backbuilding storms
along with slow storm movement. With drainage difficulties from
sewers with debris still around from irma, this could lead to some
urban type street flooding, especially along the east coast metro
areas.

The NE flow will bring a few atlantic and east coast showers
overnight. A similar pattern to today is expected on Sunday, though
stronger winds should bring a little faster storm motion.

Early to mid next week: hurricane maria is forecast to continue its
northward track roughly parallel, but east of the us coast through
mid week. As it lifts north of the region on Monday, west-northwest
mid level flow in it's wake will bring a very dry airmass down the
peninsula. Enough moisture lingers for scattered showers and storms
Monday and Tuesday, with the steering flow favoring the east coast.

Coverage becomes more isolated Wednesday through Friday as pwats
drop below 1.5", with areas north of the i-75 corridor
potentially remaining dry.

Marine... Hurricane maria is forecast to move to the north well east
of florida and the central bahamas over the next few days. As the
storm moves north of the bahamas, we will see an increase in the ne
swell that has been in place in the atlantic. Seas may build to 5-
8ft offshore broward and palm beach counties, with swells 4-6ft at
12-13 seconds from Sunday through midweek. Based on the timing of
the seas, a small craft advisory is now in effect for the palm beach
waters starting this evening.

Pressure gradient will be strongest today with NE winds 10-15kts in
the atlantic and around 10kts in the gulf. Winds will diminish to
around 10kts in the atlantic and 5-10kts in the gulf by Sunday, with
prevailing winds becoming more northerly through early next week.

Beach forecast... Increasing northeasterly swells will be the
concern into the upcoming week. Strong rip currents have continued
to be reported along the palm beaches, and will likely continue to
through much of the upcoming week. A high risk for rip currents
remains in effect for palm beach county today, which will likely
have to be extended further south as we head into next week as the
swells from maria move in.

With the northeast swell forecast to build to 5 to 6 feet,
especially off palm beach county, there will be the potential for
breakers over 10ft, especially at high tide, by Sunday night. High
surf and beach erosion are a significant possibility, which may
necessitate a high surf advisory as early as tomorrow..
