807 pm edt Thu jul 18 2019

Update
Mid level ridging centered across the deep south will spill across
much of the gulf region overnight while at the surface atlantic
high pressure stretches westward... .Through central fl and out
over the gulf of mexico. The atmosphere continues moist with
model pwat values of 1.8 to around 2 inches.

This afternoon was on the active side convection wise but less so
than yesterday. There were only a couple of special weather marine
statements and one or two reports of small hail. Currently some
patches of light rain were over central counties with a few
showers and a storm or two in the nature coast... Anticipate these
ending by 9-10 pm. Overall the forecasts look ok but will start
cleaning them up for the near term to reflect the ongoing
conditions.

Aviation
19 00z TAF cycle. PrevailingVFR with bkn mid and high clouds.

Afternoon convection seems to have pretty much wound down at least
near the major terminals and will just carry vcts til around 02z.

Anticipate shra tsra starting around 17z and continuing through
the period. Afternoon sea breeze flow is now collapsing with
light and vrbl winds over night... Se to sse aft 14z... Then SW aft
18z.

Marine
Winds seas no more than 10 knots 2 feet although locally higher
in and near thunderstorms. Atlantic high pressure extends across

afternoon onshore sea breezes. The axis of this high pressure
settles down across south fl early next week with the flow
becoming south to southwest.

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.
