Update
Tropical storm nestor continues to move quickly neward through the
c gulf this evening with bulk of convection and storms well east
of the center to impact the local area through the night and into
Saturday. Continue all tropical storm, surge and additional hazards
for the event. Main concern at this time will be additional
vigorous rotating thunderstorms in the E gulf as seen on radar
tonight as they move towards shore. Marginal risk of severe storms
through the night as numerous atmospheric dynamic fields remain
elevated for damaging winds and isolated rain wrapped tornadoes
main threats along with heavy rain for localized flooding
possibilities. Will continue to closely monitor radar and
evolution of TS nestor while updating grids and forecasts as
needed.

Aviation
Flight conditions gradually deteriorating as rain shield moving
ashore with embedded isold tsra this evening. Expect rounds of
convection through the night into Saturday with widespread MVFR
and locally ifr CIGS vsby along with gusty winds shifting from e
to SE then S into Saturday.

discussion...

tropical storm nestor will be the main player for the next 48 hours.

Nestor is over the central gulf of mexico moving quickly northeast
toward the florida panhandle. It will likely make landfall early on
Saturday, then continue moving away through the rest of the weekend.

Showers and thunderstorms have been increasing in coverage and
intensity today. So far they have remained mostly beyond 60 miles
from the coast, but as nestor moves northeast, the convergence
boundary associated with a weak frontal boundary will lift
northeast, allowing these storms to move toward the coast. The main
impact will be overnight tonight into Saturday morning. The main
threat will be the potential for damaging wind gusts and isolated
tornadoes.

Coastal flooding storm surge will be an issue tonight through
Saturday as winds turn more southerly, then southwesterly as nestor
moves by. Expecting 1 to 3 feet in tampa bay, 2 to 4 feet from
clearwater beach to chassahowitzka, and 3 to 5 feet north of
chassahowitzka.

Large waves and gusty winds will also result in high surf and
dangerous rip currents through at least Saturday, and possibly into
Sunday as well. Even after the winds diminish, wave energy will
continue to propagate toward the coast on Sunday.

Flooding from rainfall is not expected to be a big issue due to the
fast movement of the storm. That said, if rainbands set up over one
particular area for any length of time, nuisance type flooding could
certainly occur.

Sustained wind impacts from nestor should be confined to levy
county, and mainly near the coast. As mentioned above, stronger
storms could bring damaging wind gusts to just about anywhere in our
area.

We return to some semblance of normalcy on Monday. A warm front will
lift north on Monday bringing some rain chances to the region, but
most of this will remain over the gulf waters. A cold front will
move southward through florida Tuesday and Wednesday with cooler and
drier weather moving in behind it. This will not be a strong cold
front given the time of year, and while it will feel better for a
day or two, temperatures will only drop off to about where they
should be this time of year.

Warmer and more humid air will make its way back into the region by
Friday.

Marine...

widespread showers and thunderstorms will move into the waters today
as tropical storm nestor moves northeast toward the florida
panhandle. Hazardous boating conditions will persist through
Saturday night, followed by improving conditions during Sunday. Seas
will be slow to subside on Sunday as residual swells from nestor
continue to move toward the coast.

A cold front will move into the waters on Tuesday and be south of
our waters by Wednesday morning. Northeast winds could reach 20
knots behind the front Wednesday.

Fire weather...

no significant fire weather issues next several days. Dry air behind
the cold front on Wednesday is not expected to result in relative
humidities below 35 percent.

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.
