Marine Weather and Tides
Gulfport, FL

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.

GMZ800 Synopsis For The Coastal Waters From Bonita Beach To Suwannee River- 1049 Am Edt Fri May 25 2018
Synopsis..Weak high pressure over the atlantic will exit to the southeast the remainder of today with afternoon seabreeze showers and Thunderstorms moving offshore during the evening hours. Marine conditions will begin to deteriorate later tonight and into the upcoming holiday weekend as newly formed subtropical storm alberto now over the northwest caribbean sea moves slowly north into the north central gulf, and then toward the north central gulf coast late in the weekend. Increasing southeast to southerly winds and building seas along with squally showers and isolated Thunderstorms will produce hazardous boating conditions and small craft operators should remain in port until conditions improve early next week. For additional information on subtropical storm alberto see the latest advisories being issued by the national hurricane center in miami.

update...

an increasingly moist and unstable airmass (pw's approaching
2 inches during the afternoon) combined with daytime heating
and the sea breeze will allow scattered to numerous showers
and isolated thunderstorms to develop over the region later
this morning and into the afternoon with a southeast steering
flow favoring the greatest convective coverage and highest
pops setting up along and to the west of the i-75 corridor.

The increasing moisture will also support the possibility
of some locally heavy rain in some locations, and with the
ground already quite saturated from recent rains, some minor
flooding of low lying and poor drainage areas will be
possible along with the ponding of water on roadways. In
addition deadly lightning strikes and gusty winds up to 40
mph will be possible with the storms. The current forecast
has a good handle on all of this with no morning update
required at this time.

Marine...

weak high pressure from the atlantic extending west across
the northern peninsula will maintain a southeast wind flow
around 10 knots with seas of 2 feet or less over the gulf
waters the remainder of today with a weak onshore sea breeze
component developing along the coast during the afternoon
along with increasing chances for showers and isolated
storms. Current forecast is in good shape with no changes
expected in the next forecast issuance around 10 am.

Marine conditions will begin to deteriorate later tonight
into the weekend as wind an seas begin to increase along
with an increasing risk for rip currents along area beaches
as an area of low pressure moves north into the east-central
gulf. All mariners and marine interests should continue to
monitor the progress of this potential tropical system. For
additional information on this system please see the special
tropical weather outlook being issued by the national
hurricane center in miami.
