Discussion
Rain chances will be on the upswing this week with today likely
being the driest of the next several days. Ridging aloft across
the gulf south will gradually weaken during the period while a
weak mid level trough low over the eastern gulf translates
northward to the northeast gulf coast and the southeast conus
early in the period. As this all happens, moisture is forecast to
increase and deepen across the region. As a result, convection is
expected to be more widespread than what has been observed over
the last several days. Toward the end of the week and into next
weekend there is still a considerable amount of uncertainty with
the eventual evolution of energy forecast to move into the gulf
from the western caribbean and the tropical moisture that will be
associated with it. Forecast model solutions currently disagree
on the development and movement of this energy in the gulf. It's
possible convection will be more extensive by next weekend than
currently indicated in the forecast and that the pops will need to
be increased. 11

Aviation
First concern is some weak convection that could move
across mcb from now through 11z. This is weakening so there is a
good chance that there will be only minor impacts from this
activity. After that some tempo MVFR to ifr vsbys and CIGS are
possible this morning mainly around btr and mcb. After 14z all
terminals should be back inVFR status. Next concern will be
afternoon convection mainly along and north of the 10 12 corridor.

Any impacts from convection should be short lived. Cab

Marine
Still looks like for the most part onshore flow will
persist through much of the coming week. That said there could be
some minor diurnal fluctuations in the wind closer to the coasts.

Winds will generally remain below 12 kts though the week but could
be a touch higher by the end of the week east of the ms delta.

Waves seas should range mostly in the 1-3 ft range. Cab

Decision support

Decision support services (dss) code legend
green = no weather impacts that require action.

Blue = long-fused watch, warning, or advisory in effect or
high visibility event; marginal risk severe or excessive rain.

Yellow = heightened impacts with short-fused watch, warning or
advisory issuances; radar support for slight risk severe or
excessive rain.

Orange = high impacts; enhanced risk severe; nearby tropical events;
hazmat or other large episodes.

Red = full engagement for moderate to high risk of severe and or
excessive rain, or direct tropical threats; events of
national significance.

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.
