Update
Hurricane maria well east northeast of the area will continue
moving northward away from our area. Our area will be the
beneficiary of a relatively dry airmass due to strong subsidence
west of the hurricane. Light pressure gradient across our area
with relatively light northerly winds at the surface. Due to a
full day of ample sunshine, temperatures today will average above
normal.

Aviation
Vfr conditions will continue.

Marine
Advisory conditions will continue mainly due to seas with swells
from hurricane maria. Advisory conditions will continue longer for
the offshore marine zones as swells keep seas elevated there
until midweek.

Rip currents: high rip current risk today due to long period
swells from maria. High surf advisory today for NE florida
beaches due to breakers up to 8 feet.

Hydrology Coastal flood advisory extended through Tuesday for
the st. Johns river basin as onshore winds keep water levels
elevated. Minor flooding with moderate flooding at a few spots
continue at each high tide cycle from jacksonville southward.

Moderate flooding continues along portions of the santa fe river.

Minor flooding still occurring on the satilla river east of
waycross.

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.
