GMZ300 Synopsis For High Island To The Matagorda Ship Channel Out 60 Nautical Miles Including Galveston And Matagorda Bays 921 Pm Cst Thu Jan 18 2018
Synopsis for high island to matagorda ship channel out 60 nm.. Winds will gradually veer to the southeast tomorrow as high pressure moves east of the region. A coastal trough will help to enhance the chance for showers and isolated Thunderstorms Friday. Onshore flow will return by Friday afternoon and seas will build. With this return moisture and warmer temperatures, the development for sea fog will be possible late Friday as warmer air travels over the colder shelf waters. The chance for fog and precipitation will persist into Sunday evening, when the next cold front is expected to push off the coast.

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.
