Discussion
Skies across east central fl have opened up this morning with
temperatures in the 60s. Northwest winds this morning will back
today, becoming west in the afternoon, although a very weak
onshore flow might develop along the beach of the CAPE later
today. Current forecast remains on track as we continue to observe
showers over the waters east of south brevard and the treasure
coast. Special attention should be given if going to the beach.

High tide this morning is producing higher levels of water, which
in combination with a northeast swell, will produce a high risk
for rip currents, rough seas and surf and minor coastal flooding.

Aviation
Vfr conditions for the rest of today.

Marine
Northwest winds will range 10 to 15 knots today with some weakening
near the coast this afternoon. However, these will increase again
tonight to 15 to 20 knots. Seas remain high, especially for all
the offshore waters and nearshore east of treasure coast due to 6
feet swells.This is combining with wind waves and seas were at 7
feet this morning at buoy 41009 and 10 feet at 41010. Therefore,
the small craft advisory for hazardous seas continues for these
areas and it has been extended through tonight as a regular
advisory, due to winds and seas passing our local criteria.

Fire weather
Today (previous)... A much drier airmass will works its way in
across the central and northern forecast area this afternoon with
dewpoints dropping into the upper 30s to lower 40s and min rhs
from 25-35 percent. With recent rainfall and winds generally below
15 mph will hold off on need for any rfws from orange county
northward.

Mlb watches warnings advisories
Fl... None.

Am... Small craft advisory from 10 pm this evening to 8 am edt Friday
for flagler beach to volusia-brevard county line 20-60 nm-
sebastian inlet to jupiter inlet 0-20 nm-sebastian inlet to
jupiter inlet 20-60 nm-volusia-brevard county line to

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.
