Discussion
Hazardous surf and rip currents expected into Monday...

tonight... Hurricane maria about 500 miles east of daytona beach
this afternoon will continue to move northward farther away from
the area overnight. Isolated showers across the interior into
early evening will move southwestward with another area of
enhanced moisture approaching the volusia coast after midnight
with low chances for atlantic showers to move onshore. Otherwise
partly cloudy skies are expected with lows in the lower to mid 70s
as low level flow becomes light north to northwest after midnight.

Monday... Short range models indicate some enhanced moisture
trailing from a low level sfc trough from hurricane maria will
affect east central florida into Monday afternoon. Expect some
isolated showers across NRN sections in the morning progressing
south and reaching central SRN sections by afternoon. Will keep
rain chances around 20 percent with shower chances north and a
slight afternoon shower thunderstorm chance for central and srn
zones with this feature. Northerly low level flow is expected with
winds becoming nne NE along the east coast in the afternoon. Highs
will remain very warm near 90 along the coast to the lower 90s
for the interior.

Tuesday-Wednesday... Well below normal rain chances as the airmass
dries out even further with drier, continental air continuing to
filter into the region on the backside of hurricane maria. Most
areas will remain dry on Tuesday, but there should be enough
convergence and lingering moisture over southern areas to generate
some afternoon and evening showers. For right now, only going with
a slight chance (20%) of showers south of a line from lake kissimmee
to melbourne. GFS and local 6 km WRF seem to like this scenario
with the ECMWF being less enthusiastic. Even drier air is forecast
to be in place on Wednesday but again enough moisture remaining
along the treasure coast is enough to warrant a slight chance of
showers.

High temps low 90s interior and upper 80s to near 90 near the coast.

Low temps will be in the low to mid 70s.

Thursday-Sunday (modified previous)... An anomalously dry atmosphere
will keep precip chances low through Thursday. Rain chances begin
to increase on Friday (to around 30%) with most areas seeing a
40-50% chance for Saturday and Sunday. Ample sunshine and light
west flow will boost temperatures several degrees above average
through late week, even along the coast. Afternoon highs in the
low 90s and min temps in the low to mid 70s. Swells from maria
will be slow to subside through mid week, keeping conditions in
the surf zone quite hazardous. A high risk for rip currents is
expected to continue through the week.

Aviation
MainlyVFR through tonight with isolated shra forecast to move
toward the kdab vcnty late tonight into early Monday morning.

Models hint that some MVFR br patchy stratus may develop across
the NRN interior terminals (klee, perhaps to ksfb vcnty) toward
sunrise but have left out of terminals for now. Generally low shra
chances expected Monday spreading from NRN terminals (kdab-ksfb)
to central terminals (kmco-kism) by early afternoon.

Marine
Tonight... Ne-n winds to 10-15 knots tonight expected with large
swells continuing across the waters from maria. Expect seas to
7-10 feet near shore and up to 12 feet well offshore. Small craft
advisory conditions continue.

Monday... N NW winds across the waters to 10-15 knots NRN areas to
around 10 knots across the south. Seas will remain high in
northeast swells with seas to 7-9 ft near shore and up to 10-12 ft
offshore.

Tue-thu... Swells from distant hurricane maria will be slow to
subside through mid week, though winds will relax considerably as
the local pressure gradient weakens. Seas will remain at or above
sca criteria (espec offshore) through mid week before improving
late Wednesday and into Thursday.

Hydrology
Basin average rainfall amounts are expected to remain very low
through the next four days allowing the st johns river levels to
slowly fall into mid week. Current conditions indicate river
levels remain in the moderate to major flood category along the st
johns but slowly improving conditions are expected into late week.

The shingle creek at campbell will continue a slow fall but remain
above action stage through at least Monday.

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.
