Discussion
Short term (tonight-Sunday)... Satellite and model analysis show a
broad trough across the east half of the nation, which is
gradually transitioning into a closed upper level low. Model
solutions show this feature lingering around the northern gulf
coast through the rest of the weekend, along with an associated
area of showers and thunderstorms remaining across most of the
state through Sunday. Sounding data from mfl still shows pwat
values above 2 inches, which combined with daytime heating will
support afternoon convection again on Sunday, especially along sea
breeze boundaries.

Wpc keeps the eastern half of south florida under a marginal risk
for excessive rainfall this evening and again Sunday, which could
translate in localized urban street flooding, especially along
the east coast metro areas.

Long term (Sunday night-Thursday)... Hurricane maria continues to
move northward, and lifting north of the region by Monday. In its
wake, very dry air will filter into the region with showers becoming
scattered at best early next week. Even drier days are expected
for the second half of the work week with mainly isolated showers
each day.

Marine
Hurricane maria continues to move north while remaining
east of florida and the central bahamas. An associated NE swell
across atlantic waters will bring seas building to 5-8 ft offshore
on broward and palm beach counties tonight, and swells 4-6 ft at
around 12-13 seconds from Sunday through midweek. A small craft
advisory remains in effect for the palm beach waters starting this
evening. 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
Northeasterly swells will result in strong rip currents along the
palm beaches, and will likely continue through much of the
upcoming week. A high risk for rip currents is now in effect for
palm beach county through Sunday, which will likely have to be
extended further south as we head into next week as the swells
from maria move in.

W&&

Aviation
Showers will continue to develop through the day with coverage of
thunderstorms increasing this afternoon. The convective focus is
expected around boundary collisions today, mainly inland. Bouts
of sub-vfr conditions with convection could require short-fused
amendments today. Convection may continue along the east coast
tonight and again into the morning.

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.
