Marine Weather and Tides
South Pasadena, FL

Version 3.4
What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Update
No major updates needed at this time with just a few minor
tweaks to account for current conditions. Right now we
still have a few light sprinkles in the interior with the
only thunderstorm activity happening in lee county, but all
showers should dissipate during the overnight hours. With
the subtropical ridge to our south we can expect a few
showers and thunderstorms to form once again right along the
coast tomorrow morning before moving quickly inland with
the seabreeze in the afternoon.

Aviation (21 00z through 22 00z)...

thunderstorms continue to develop in the vicinity of
kfmy krsw as of TAF issuance time, and these will impact
operations at these terminals through 01 02z before
dissipating. Elsewhere, storms are well inland from
terminals further north, and prevailingVFR conditions are
expected through most of the overnight. W wnw winds diminish
and become light SW or variable within a few hours of
sunset. Late at night, a few showers will be possible
migrating onshore in the vicinity of ktpa kpie ksrq. This
trend of widely scattered coastal showers continues into the
daylight morning hours. More robust, but typical summer
type storms will develop along the i-75 corridor by early
afternoon. Expect a light SW flow to shift W wnw at 8-11
knots during the afternoon for all terminals.

Marine...

the ridge of high pressure will sink south and hold across the
florida straits for the remainder of the week setting up westerly
flow across the waters. Isolated to scattered showers and
thunderstorms are expected through the week, especially during the
late night and morning hours. Winds and seas could be higher near
these storms, otherwise hazardous boating conditions are not
expected.

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.
