Marine Weather and Tides
Indian River Shores, 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.

AMZ500 Synopsis For Flagler Beach To Jupiter Inlet Out To 60 Nm- 1021 Am Edt Sat Jun 23 2018
Synopsis..The axis of the atlantic high pressure ridge will remain south of the local waters through tonight before drifting slowly northward across central florida early next week. The resulting winds will shift from a light to gentle west to northwest breeze early today, then continuing to veer through the afternoon, to a south and southeast breeze next week. Benign sea conditions will continue at least through the middle of next week, though the treasure coast waters may see short wave periods due to the lee-side shadow of the northern bahamas. A few stronger storms are possible today, mainly along the immediate coast and over the intracoastal waterway.
Gulf stream hazards..None. The approximate location of the west wall of the gulf stream based on the real time ocean forecast system as of Saturday june 23rd. 42 nautical miles east of ponce inlet. 32 nautical miles east of port canaveral. 25 nautical miles east of sebastian inlet. 16 nautical miles east of fort pierce inlet. 9 nautical miles east of saint lucie inlet.

Highest heat index readings likely between 100f and 105f areawide
again this afternoon...

Few strong storms possible again late today across east central

current-tonight... The surface ridge axis over the fl straits is
forecast to lift northward toward south-central fl through late
day tonight. As this occurs the associated high center will travel
northward parallel to the western fl coast over the eastern gulf.

This will allow our early morning light W wsw surface winds to veer
to northwesterly through the day and perhaps northerly. Winds at the
coast will back to onshore following ecsb formation and slow march
inland. The current 915 mhz CAPE wind profilers continue to show
deep, but light (5-10 kts) westerly flow through the atmospheric
column. Mid-level winds remain fairly light and expect our present 5
kt west storm steering flow to veer to northwest or north later
today this evening. This may allow for future storms today to zipper
southward down the ecsb. The latest 10z kxmr sounding has came in
very moist with a pwat of 2.16 inches and 700 500 mb temperatures of
+9.9c -7.5c respectively. The warmer temperature at 700 mb yesterday
held off developing convection until later in the afternoon. It will
be interesting to see if that is again the case. Forecasted pwat
values will average between 2.00-2.25 inches over much of the cwa,
but a tight gradient further north with drier air could limit pwats
north of i-4 to around 1.70 inches.

The ecsb will develop today and venture slowly inland, likely
further into the interior than previous days with the overall
opposing flow weaker. Again, we should see initial shower storm
activity firing along ahead of the inland moving wcsb across wcntrl
fl. Some activity is forecast by the local hrrr to also develop
along the ecsb across the coastal counties. This activity should
increase in coverage as the afternoon grows old with further
mesoscale interactions igniting new convection along the way. Late
afternoon outflows pushing towards the ecsb will prompt pulse strong
storms just inland from the coast and eventually further into the
interior with larger outflow sea breeze boundary collisions.

Convective precip debris will slowly dissipate during the evening.

Mariners on inland lakes as well as the intracoastal near shore
atlantic waters will need to keep an eye to the sky westward again
today for developing approaching storms. Yet, another reminder that
lightning can strike at least 10 miles away from the parent
thunderstorm. Overall, pops again should favor both the
central eastern peninsula and southward from orlando where highest
chances look appropriate. Models, again, show favorable diffluence
aloft late in the day across the central and east central fl
peninsula. For pops, expect 30-40pct north of i-4 with increasing
numbers to 60-70pct southward from here for late day early evening
convective fireworks.

Main threats continue to be torrential downpours, frequent cloud to
ground water lightning, small hail, and gusty winds to around 50
mph. Local ponding of water (temporary) on roadways may lead to
nuisance flooding, especially in areas that have seen abundant
rainfall recently.

Highs will average in the l90s again today and combined with
moisture values will drive highest heat indices in the 100f to 105f
range during the late morning and afternoon ahead of convective
development. Cloud debris will thin again through late
evening overnight. Overnight mins forecast well into the 70s with
conditions humid.

Aviation Warm 700mb temps may mitigate earlier convective
development again across ecfl, though deep layer moisture remains
very high. The ecsb should develop a little sooner today and move
further into the interior than previous days. Mesoscale outflow
boundaries and sea breeze collisions will favor higher pops south
from mco this afternoon evening, where a few cells could be on the
strong side with gusty winds and frequent lightning. MVFR-ifr vsbys
and g30-40kt expected beneath stronger storm cores once again.

Marine Today-tonight... .Surface ridge axis over the fl
straits is forecast to lift slowly toward the south-central fl
peninsula over the next 24 hours. The associated high pressure cell
will also advance northward parallel to the west fl coast over the
eastern gulf. Our light, early morning, offshore flow is forecast to
veer through the day to NW N NE E as a result as the overall
pressure gradient remains light. The ecsb should develop a little
quicker today and venture further inland than past days. The light
westerly storm steering flow will also veer through the afternoon to
out of the NW and n. A few cells could still affect the intracoastal
and near shore atlc waters this afternoon evening with heaviest
concentration south from the CAPE and greatest timing late
afternoon early evening.

Torrential downpours, small hail, frequent cloud to water lightning,
and gusty winds in excess of 35 kts all in play. Winds seas locally
higher INVOF of storms. Outside of storms seas generally 1-2 ft
which will allow for favorable boating conditions. Mariners will
still need to keep an eye to the sky westward later today.

Hydrology The saint johns river above lake harney near geneva
remains at action stage. A very slow rise in the river stage is
forecast through this weekend and into early next week, however the
river is forecast to remain below flood stage. However... Any
additional precip upstream from this watershed could promote higher
levels and perhaps an upgrade to minor flood stage. Refer to the
latest river statements (miarvsmlb) issued by the NWS office in
melbourne for specific details and river stage forecasts.

Mlb watches warnings advisories
Fl... None.

Am... None.

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.
