Update
Update for 18z aviation.

Aviation
Ceilings have generally improved to about 3500 feet, though some
lowering is expected again tonight. Visibilities prevailing 6
miles except for early this afternoon where a broken band of
heavy rain is near btr, mcb, and hdc terminals visibility around 3
miles is possible. Winds will remain gusty from the south with
gusts over 20 knots expected through the early evening hours.

Winds then drop tonight except for more coastal terminals msy,
new, asd, gpt, and hum. Ak

short term...

conditions continue to slooowwwlly improve this morning with
respect to a few variables. Winds have shifted to a southeasterly
direction and continue to ease. As the storm further weakens and
moves inland, expect to see further improvement over the next 36
hours.

Heavy rainfall will remain an issue, but only within banding
structures that set up and train over the same areas. The rainfall
accumulation gradient today will set up perpendicular to the
axial banding. This simply means that there will be locations
that will receive very little rainfall amounts where subsident
warming air between banding structures is located and relatively
much higher rainfall amounts where convergent lift along these
bands is occurring. The banding rainfall will be dynamic as cindy
moves inland and will slowly shift during the day. This should be
enough to allow most areas to receive small amounts an inch or
less while locations that spend the most time under these axial
bands could observe up to 3 inches or better. A flash flood watch
will remain through 7pm today. The watch will be mainly for areas
that fall under these bands as they slowly shift through the day.

Winds have eased a bit and shifted to southeasterly. This has
helped to allow the bulk of water over lake pontchartrain to
begin slowly receding from south shore areas. This causes this
water to be forced via winds and sloshing to the northshore
locations causing moderate coastal flooding in locations normally
prone to flooding. A lot of water has piled into the lakes and
adjacent areas. Eventhough this water was forced into these areas
over a relatively short time frame, there is no meteorological
forcing to alleviate the problem just as fast. This means we will
need to rely on gravity drainage to get this water back out. Winds
will impede this to a certain degree as they remain around 20
knots off and nearshore this morning. For all these reasons we
are expecting a very slow improvement(lowering) in water levels
over the next 48 hours. Areas normally prone to coastal flooding
will continue to have flooding issues through Friday. A coastal
flood advisory will remain through Friday.

Where the banding structures exist, there will continue to be an
issue with tornadic cells. A tornado watch has been posted for the
entire area through 1 pm today for this threat.

Long term...

as the remnants of cindy gets picked up by a synoptic trough
moving through the country Thursday night into Friday, it should
be capable of forcing a surface trough southward into the area by
Sunday or Sunday night before becoming stationary while
weakening. This will provide a continued focus for sh TS to form
daily along and south of the boundary through Monday. Global model
solutions are doing their best to send this boundary through the
area with some northerly winds component and somewhat drier
conditions by Tuesday or Tuesday night. This could actually be a
good possibility as the large mass of warm tropical air moves
north, the compensation on the back side should send the front
into the northern gulf... Or at least we are being optimistic.

Aviation...

prevailing MVFR ceilings ranging from 1500 to 2500 feet can be
expected through around 15z. After 15z, ceilings could improve into
vfr range around 3500 feet. However, some build down back into MVFR
range is expected after 00z tomorrow. Also have prevailing MVFR
visibilities ranging from 3 to 5 miles due to the risk of scattered
convection impacting the terminals. Winds will remain gusty from the
south with gusts over 20 knots expected through the afternoon hours.

32
marine...

conditions on the coastal waters will gradually improve through the
forecast period. A tight pressure gradient associated with the now
inland tropical storm cindy will keep strong southerly winds of 20
to 30 knots in place over all of the waters today. Very rough seas
of up to 12 feet will also be found over the open gulf waters due to
these winds. Tides will also remain well above normal due to the
onshore flow. Tonight and tomorrow, the pressure gradient will ease
and expect to see winds in the open waters fall to 20 to 25 knots
tonight and 15 to 20 knots by tomorrow afternoon. Over the lakes and
sounds winds should fall to 15 to 20 knots tonight and 10 to 15
knots by tomorrow afternoon. Tide levels will also begin to finally
fall off as the onshore flow weakens. Seas will remain fairly rough
offshore, but should drop to 6 to 8 feet by tomorrow afternoon.

Finally, by the upcoming weekend a return to a more normal summer
regime with persistent southeast flow of 10 knots or less and seas
of 3 feet or less can be expected. A weak cold front should then
push through late Sunday night and Monday shifting winds to the
northeast and increasing wind speeds to 10 to 15 knots Monday night
as the cooler and drier air moves over the warmer gulf waters. 32
