High rip current risk ends at 10 am...

short term (today)...

broad high pressure over the eastern half of the gulf this
morning along with a low on the mid-atlantic coast will
maintain a dry westerly flow across the area. The 12z tbw
raob had 0.42 inches of pwat and west winds through the
column. The early morning cloudiness that came in off the
gulf is eroding away with skies becoming mostly sunny. All
forecasts looks good but will update at 10 am to clear the
rip current headline. Decreasing winds and seas have lowered
the risk of rip currents.

Marine...

westerly continue today with seas of no more than 10 to 15
knots. Winds begin to back tonight as high pressure moves
east of the waters... With benigh speeds.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
