a low pressure system moving through the great basin will move
into the central and southern rockies with onshore flow weakening

slopes of the mountains continue to slowly subside with strongest
gusts between 40 and 50 mph across the upper deserts and in the

with patchier night and morning coastal low clouds and fog for the
middle part of the week with greatest coverage for san diego
county.

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.
