Hazardous marine and beach conditions into Sunday...

Discussion
Progressive upper pattern continues as upper low slowly
lifts out of the deep south tonight through the mid atlantic
Sunday to NW atlantic Monday. Residual energy wrapping over
the N gulf coast tonight to generate cloud cover and another
round of light rain into early Sunday morning mainly nature
coast and coastal tampa bay areas for 20 pops in those
locations. May also see some localized shallow field fog in
normally fog prone areas but dont expect it to widespread
enough to mention in grids. Overnight low temps remain
slightly above seasonal averages.

Large long period swells moving ashore will produce large
breaking waves and dangerous rip currents late this afternoon
into Sunday.

Brief quasi-zonal flow over the gulf of mexico and florida
by late Sunday thru tues with benign weather conditions
expected.

Next southern stream storm system to dev and move eastward
mid week as upper trough low moves out of tx into the deep
south with associated surface low pressure along the gulf
coast and cold front into the local area Wed nt through
Friday with several rounds of showers and some storms ahead
of and along the front. Some model differences in exact
timing, location and impacts of features so will go with
consensus at this time.

Aviation
GenerallyVFR conditions with sct-bkn cloud deck AOA 3-5k
ft as band of light rain continues with some MVFR CIGS and
vsbys early this afternoon. Expect mid clouds to remain
over the region tonight and may see some localized field fog
at usual fog prone terminals towards morning.

Marine
Moderate westerly winds continue over the E gulf while long
period swell of 9-12 ft at 10-11 seconds showing on E gulf
buoys this afternoon. Will hoist SCA for hazardous seas as
the swells will propagate over the waters tonight into
Sunday. Lighter winds and seas late Monday into mid week,
then next storm system to move into gulf Thu thru late week
with elevated winds and seas.

Fire weather
Recent rainfall, high rhs and light winds to prevent any
fire weather concerns.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
