10/9/2019 Updated the Marine Zones. 9/4/2019 Fixed the weather maps due to NOAA moving them. 7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports. 6/2/2019. Many thanks to a user for reporting an error on one of the Edit pages. The switch to PHP 7.2 caused many pages that previously worked to quit working. I fixed many but I still depend on users to report ones I missed. Please report errors HERE or send an email to me at L-36.com. Allen |

GMZ800 Synopsis For The Coastal Waters From Bonita Beach To Suwannee River- 813 Pm Est Mon Dec 9 2019
Synopsis..High pressure will persist over the waters through Tuesday night. A cold front will move into the northern waters on Wednesday, and then into the central waters Wednesday night where it will stall out through Thursday. Ahead of the front, there is an increasing threat for sea fog across the nature coast, which may eventually extend south to the mouth of tampa bay. SEa fog may persist through Wednesday morning over the cooler northern shelf waters. As the front moves into the area increasing northeast winds and seas are expected, with a period of cautionary or near advisory level conditions possible by late Wednesday into Thursday, especially across the central and northern waters.

Area Forecast Discussion National Weather Service Tampa Bay Ruskin FL 721 PM EST Mon Dec 9 2019
UPDATE. A generally quiet night is expected with temperatures cooling into the upper 50s to mid 60s by dawn. Tomorrow's weather will be very similar today, with a cool start to the day and a warm afternoon as highs climb into the low-to-mid 80s. The only concern overnight is the development of patchy fog. With fairly calm winds and high dewpoints, areas (particularly from Tampa Bay Southward) could see fog develop in the early morning hours. This should begin to clear once the sun rises.
As a front approaches our area late Tuesday night into Wednesday, stalls, and then advects back northward as a warm front, conditions will begin to deteriorate, with a rainier latter half of the week expected. Overall, the forecast remains on track and no significant changes have been made or are anticipated.
AVIATION. VFR conditions are expected to prevail, but lower ceilings,and mist are possible from 10Z onward through as late as 15Z with light and variable winds. As temperatures warm, ceilings will lift, and winds will become SSW in the afternoon.
Marine. Conditions remain fairly calm and quiet overnight. Some fog is possible in extreme northern coastal waters, but conditions do not look conducive for widespread fog. There is an increasing threat for sea fog tomorrow night for the Nature Coast extending down towards Tampa Bay ahead of a cold front. This front will move southward and then stall before moving back north mid-week. This will quickly eliminate the fog threat Wednesday into Thursday, but could cause seas to approach cautionary criteria.

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. |
