sw fri. Very deep moisture with precip wtr values in the 1.5 to
2 inch range expected late Thu into Thu night... These values
are at the MAX observed for mid to late dec. With good lift
ahead of the upr trf and deep moisture expect bouts of heavy
rain Thu into early Fri with bulk of mdls showing 2 to 3 inches
over the region, with localized higher amounts. Flood potential
will need to be monitored given the extraordinary excess of
rainfall that has occurred in the region over the past 4 months.

Gusty winds will also accompany this storm system and will
monitor for poss wind advry parts of imd cst. Will also
continue to mention isolated thunderstorms Thursday afternoon
into Thursday night ERN third as weak instab poss near cst. If

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.
