Convective coverage is limited compared to previous days, mainly
along the sea breeze boundaries this afternoon. Convective
coverage will increase inland as the sea breezes advance and
boundary collisions occur. Activity should diminish this evening
with light winds expected.

south florida is in a drier pocket of air this morning, which has
helped to minimize convection. Hurricane maria continues well to
our northwest with minimal influence over the weather. Main
concern continues to be the marine hazards along the atlantic
coast and waters. No additional updates expected through noon.

Have a great Monday morning!

today through Wednesday: the florida peninsula will be in between
hurricane maria, as it continues its northward track well to our
east, and a broad upper level low over the northern gulf coast. This
low is expected to briefly merge into the larger circulation around
maria early this week, leaving a trailing upper level trough across
the state. West to occasionally northwest flow around these features
will bring drier air into much of the state, leaving a moisture
gradient across south florida.

Both seabreezes will develop the next few afternoons, though the
wind direction will mean a late start to the east coast seabreeze
as it remains relatively near the coast. Expect showers and a few
storms to develop along the seabreezes during the afternoons,
favoring the east coast late in the day. Overall rain chances will
remain below normal the next few days. If the dry air is able to
penetrate far enough south, wouldn't be surprised if areas near
the lake remain completely dry on some days.

Late week: hurricane maria is forecast to brush the outer banks mid
week before racing off to the northeast across the open atlantic. As
it does, the upper level low that briefly merged with the larger
circulation around the storm will be left behind across the
northeastern gulf north florida late week. Midlevel flow, while
fairly light, will tap into deeper moisture, bringing pwats back
over 2" across the region late week. Both the GFS and ECMWF are
showing the potential for weak surface low development off to our
northeast along the moisture boundary as the upper level low lifts
out this weekend.

Regardless, a shift back to a wetter pattern is expected across
south florida to end the week. Showers and storms increase in
coverage across the region by Thursday, driven by the inland
movement of both the gulf and atlantic seabreezes. Depending on
exactly how and where the boundary sets up, more numerous activity
is expected Friday into next weekend with the potential for some
heavy rainfall.

Marine... Northeast swells from hurricane maria are already making
their ways through the local atlantic waters, expected to peak
around 5-6ft later today. This will continue to lead to seas of 7-
8ft off the palm beach county coast, with lower amounts in the
remainder of the local atlantic. Both swells and seas are expected
to linger through much of the week.

A small craft advisory remains in effect through through late
Wednesday, and may need to be extended beyond that in the coming
days. The rest of the atlantic waters will reach cautionary criteria
through much of the week.

Winds are expected to be light and seabreeze driven through the
week, with no boating concerns in the gulf waters.

Beach forecast... Long period northeasterly swell potentially
reaching 5-6ft the next few days at periods of 12-13 sec will
create the potential of 10+ foot breakers along the palm beach
county coast. A high surf advisory remains in effect for coastal
palm beach county highlighting the threat of coastal erosion and
dangerous surf conditions through much of the week. In addition a
high risk for rip currents will be in place at all atlantic
beaches through much of the week.

If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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 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.
