Update
Easterly surge pushed offshore overnight with leading edge
now well into the gulf. Winds have already diminished over
land, but expect some increase again as mixing occurs with
the heating of the day. 12z tbw sounding showed 20 to 30
knot easterly winds just off the surface up through 3000
feet. This will result in some wind gusts in the 20 to 25
knot range today.

Otherwise, mainly high thin cirrus clouds streaming across
the region which will do little to block out the sun.

Temperatures will climb into the upper 80s across most of
the area, with a few locations flirting with 90 degrees.

Records are generally in the lower 90s, so not expecting to
break any today.

Only minor tweaks were made to the grids with no text
update required at this time.

Aviation
Vfr next 24 hours. Enhanced easterly flow should keep sea
breezes from developing today.

Marine
All available reporting stations are below small craft
advisory levels, so have cancelled the advisory. Winds
offshore are still in the 15 to 20 knot range with some
higher gusts, so will maintain exercise caution headlines
there.

Another easterly surge is likely to develop tonight
with advisory level winds returning to the waters beyond
20nm this evening. Will evaluate the 12z model guidance
today and issue another SCA if needed with the afternoon
package.

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.
