GMZ800 Synopsis For The Coastal Waters From Bonita Beach To Suwannee River- 908 Am Edt Sun Apr 30 2017
Synopsis..High pressure across the waters from the atlantic will continue through tonight then begin to slide east Monday as a cold front moves into the gulf waters. This front reaches the east gulf Monday night then stalls across the state and becomes diffuse through midweek before lifting north. A stronger front may approach the area late in the week. Some robust winds will continue this morning then diminish but pick back up this evening...with exercise caution headlines in place. Showers and Thunderstorms will provide locally higher winds and seas.

Update
Lots of clouds across the region this morning as an upper-
level short-wave trough moves by. Clouds will gradually thin
from west to east today, with sunshine returning to the
beaches around noon or so, then to the rest of the area this
afternoon.

Moisture has increased since yesterday, so we will likely
see more cumulus development during the afternoon hours.

This combined with slightly cooler low-level temperatures
will keep us a few degrees cooler than yesterday, although
still likely reaching the lower 90s.

We may see a band of sea breeze showers and thunderstorms
develop late this afternoon and early this evening from
about the tampa bay area north. These would occur primarily
near or west of i-75 and move northwestward toward the gulf.

Last nights surge has brought seas up to 4 feet just
offshore. Winds are forecast to remain rather gusty and turn
more southerly and a bit onshore right at the beaches
during the afternoon hours. The combination of gusty winds
and choppy seas will result in conditions favorable for the
generation of strong rip currents. Will be issuing a rip
current statement with the morning update for pinellas and
hillsborough counties south through lee county.

Aviation
Vfr expected next 24 hours. Gusty southeasterly winds may
briefly turn southerly as a sea breeze tries to advance
inland between 20z and 00z.

Marine
Seas are about a foot higher than forecast in the nearshore
waters, so will update to include these higher seas.

Otherwise expect rather robust southeasterly winds through
the early afternoon hours, then some relaxation of the winds
as a sea breeze develops. Winds will come right back at 15
to 20 knots again tonight. A weak frontal boundary will move
into the region Monday night but only serve to collapse the
pressure gradient and result in lighter winds and seas
through mid-week.

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.
