West winds in the 7 to 10 knot range this afternoon will become light and variable after 02z tonight, then becoming west at 6 to 8 knots Wednesday afternoon as the sea breeze redevelops and moves inland. Prev discussion issued 943 am edt Tue sep 26 2017 update... weak high pressure to the northwest and hurricane maria moving slowly north over the atlantic east of the mid atlantic coast will allow some drier mid level air to filter into the forecast area the remainder of the day. This drier air should keep overall rain chances below normal, however adequate low level moisture combined with daytime heating should result in isolated to widely scattered shower storm development over inland locations along the sea breeze during the afternoon and across southern most locations where better moisture will reside while mainly dry conditions are expected from the bay area north into the nature coast. Afternoon temperatures will climb toward 90 along the coast prior to the onset of the sea breeze, with lower 90s expected over inland areas. High-res model output and ongoing forecast concurs with |
this so a morning update will not be required at this time. Marine... light winds and slight seas are being observed over the gulf waters early this morning, and little change to current conditions expected through the afternoon with a weak pressure pattern supporting an onshore sea breeze component around 10 knots developing along the coast during the afternoon. Ongoing forecast is on track with no changes expected in the next forecast issuance around 10 am. Hydrology... while moderate to major flooding continues on the withlacoochee river in pasco and hernando counties, the river is slowly receding. As the water routes farther downstream, minor flooding is still forecasted to begin over the next couple of days in northern citrus county. The withlacoochee river has not flooded in some of these locations within the last 10+ years. Elsewhere, levels continue to recede along most of west central florida's rivers. With no widespread rainfall expected over the next several days, additional flooding is not expected to occur. Most of the flooding that occurred from hurricane irma resulted in the worst flooding many places have seen in the last 50-70 years. For example, the official crest on the peace river at arcadia of 19.20 feet was the 3rd highest on record and the worst flooding since 1933. Tbw watches warnings advisories... fl... None.

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. |
