For the evening update
Areas of light rain persist this evening over the coastal
waters... Portions of the interior... Tampa bay area... And nature
coast. Light rain is expected to dissipate over land during the
next couple of hours, but may persist over the northern nature
coast until midnight.

A flood watch continues from pasco county and north tonight... And
may need to be extended for portions of the nature coast on
Sunday. Showers and isolated thunderstorms are expected to
redevelop over the northeast gulf overnight and advect locally
onshore during the late night early morning hours. Areal flooding
persists across levy and northwest citrus counties... And any
additional rain will make it difficult for flood waters to recede.

Surface ridge axis will build across the southern florida
peninsula on Sunday which will begin a transition to a more
typical summertime pattern for the upcoming week. This will also
nudge the trough over the northeast gulf and north florida a bit
further north... However scattered to numerous showers and isolated
thunderstorms will develop across west central florida on Sunday with
the highest pops over the northern nature coast.

Tbw watches warnings advisories
Fl... Flood watch through Sunday morning for coastal citrus-coastal
hernando-coastal levy-coastal pasco-inland citrus-inland

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
