Area Forecast Discussion National Weather Service Tampa Bay Ruskin FL 1001 AM EDT Tue Oct 27 2020

UPDATE. A mixture of sun and clouds have persisted through the morning. Some pesky low clouds remain across parts of west central and southwest Florida, while sunny skies are being reported elsewhere. All the shower activity this morning is staying well off to the west over the gulf waters. Temperatures are already in the low 80's and will continue to heat up into the low 90's this afternoon, with near record heat expected. Made a slight tweak to POPs to account for latest radar coverage. Everything else looks ok for now.

AVIATION. Prevailing VFR conditions with east-southeast winds 10 knots or less expected at all terminals through the period. Scattered showers possible this afternoon, so will hold VCSH after 20Z for all terminals during that time.

MARINE. Interaction between Tropical Storm Zeta near the Yucatan Peninsula and broad high pressure over the eastern seaboard will continue to produce gusty east-southeast winds around 15-20 knots over the gulf coast waters over the next couple of days. Scattered showers and isolated storms will be possible through the end of the week. Gusty winds, dangerous lightning and rough seas can be expected in the vicinity of thunderstorms. A long period SW-W swell around 3-6 feet will propagate from Tropical Storm Zeta as it moves through the central Gulf of Mexico on Wednesday. A cold front moves through the eastern gulf waters on Friday bringing a good chance of showers and storms.

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.
