Marine Weather and Tides
Perdido Beach, AL

Version 3.4
What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Discussion Updated for latest aviation discussion below.

Aviation
00z issuance... Convection positioned over the interior this
evening and lifting slowly northward. Storms are well away from
the terminals. Thickening cloud cover over the coastal waters is
gradually lifting northward. Thus, forecasters will carry a
developing broken to overcast mid to high base cig this evening
over the TAF sites. Vsby ok with little to no precipitation
anticipated. Light south to southeast winds in the near term. 10

Prev discussion issued 355 pm cdt Sun jun 17 2018
near term now through Monday ... Weak upper ridging is expected
to build across the area tonight, and become more defined on
Monday. This building ridge will return the region to a more
typical summertime convective regime, with some isolated nighttime
showers and storms (especially near the coast and offshore) and
then scattered afternoon (about a 30 percent chance at most) on
Monday. Some of the strong afternoon thunderstorms will be capable
of producing frequent lightning and gusty winds. With a very
moist onshore flow continuing maintaining pwats in the 1.5 to 1.8
inch range, some very heavy localized rainfall will be possible
with the stronger storms as well. Lows tonight in the low to mid
70s. On Monday with less cloud cover and rain coverage, highs will
reach into the lower 90s inland and upper 80s closer to the
coast. 12 ds
short term Monday night through Wednesday night ... An upper
ridge centered over the southeast states weakens slightly while
shifting a bit southward in response to a system advancing across
the plains. A surface ridge over the region likewise weakens and
shifts southward into the northern gulf as the western fringe of
a surface trof over the eastern states noses into the extreme
southeast states. Subsidence effects from the upper ridge will
tend to suppress convective development during the period,
although there will be an uptick in potential coverage over the
eastern and coastal portions of the area especially by Wednesday
with the weak surface trof nearing the area. Have gone with slight
chance pops for the area on Tuesday then for Wednesday will have
chance pops from mobile eastward to across the western florida
panhandle and extreme south central alabama, with slight chance
pops elsewhere. Highs on Tuesday will be about 4 degrees above
normal then 2 to 3 degrees above normal on Wednesday. 29
long term Thursday through Sunday ... An upper ridge over the
extreme southeast states retreats a bit more southward through
Saturday to be oriented nearly along the northern gulf coast then
expands northward on Sunday as the plains system meanwhile moves
across the interior eastern states. A surface low associated with
the system moving across the interior eastern states passes well
north of the region during the period while a surface ridge will
be present over the eastern gulf. Meanwhile, the surface trof over
the extreme southeast states slowly weakens but this feature and
the surface low and surface ridge previously mentioned will all
combine to produce a modest and diffuse low level convergent zone
over the forecast area for much of the period. While an upper
ridge will be present over the forecast area through the period,
this feature will not be particularly strong and produces just
modest subsidence effects. Considering this, expect scattered
convective development over most of the area each day. 29
marine... A generally light to moderate onshore flow will persist
over the marine area into early next week as a surface high pressure
extends from the western atlantic into the eastern gulf of mexico.

Seas initially up to around 4 or 5 feet well offshore due to swell
coming off an inverted trough moving across the west-central gulf of
mexico will slowly subside to around 2 feet by late Tuesday, with
little change in seas then expected for the remainder of the
forecast period. Otherwise, winds and waves will only be locally
higher near isolated to scattered showers and thunderstorms. 12 ds

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.
