Isolated to scattered showers will continue to move NW and
diminish over the next several hours. This will result inVFR
conditions at all area TAF sites with sct bkn stratus from

knots except across interior central la where winds will be
light variable.

wx map shows large 1026mb sfc high over the carolinas, ridging
southwest over most of the gulf of mexico providing east-southeast
to southeast flow over the region. Trailing moisture associated
with the remnants of imelda still producing scattered showers
with the occasional thunderstorm. With rainfall still occurring
over SE tx, flash flood warning for additional rainfall continues.

For the forecast, 40-50% pops for the remainder of the afternoon
over SE tx SW la, diminishing for 20% this evening. The flash
flood watch will continue for all of southeast texas through 7 pm.

Wording of 0.5-1" with isolated higher amounts possible with
these slow moving showers.

The forecast this weekend into the middle of next week shows high
pressure building across the upper levels, but not expected to
completely suppress afternoon shower and thunderstorm
development. Thus, 20-40% for this across the region per blended
guidance seems reasonable. Above average temperatures will
continue, with lows in the lower 70s, and highs mainly in the
lower 90s.

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.
