Marine Weather and Tides
Version 3.4 |
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- 430 Am Edt Tue Oct 15 2019
Synopsis.. High pressure stretching across the peninsula continues light east southeast winds and slight seas with an onshore sea breeze component developing along the coast during the afternoon. Rain chances increase Wednesday ahead of a cold front expected to move through early Thursday. Southerly flow from a disturbance in the central gulf of mexico will draw deep moisture north bringing additional rainfall through the upcoming weekend.

(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus62 ktbw 150843 afdtbw area forecast discussion national weather service tampa bay ruskin fl 443 am edt Tue oct 15 2019 Discussion High pressure aloft and at the surface continues to influence conditions across the region with generally partly cloudy skies and variable to light easterly flow. Shower activity has affected a few southern offshore locations overnight although nothing widespread. More of the same can be expected over the next 24 hours with a gradual increase in westerly flow aloft as the upper ridge retreats south in response to a deep closed low moving across the great lakes region. Surface flow will become southwesterly Wednesday as the surface ridge weakens and moves east into the atlantic in advance of an approaching front sinking into the region associated with a developing low pressure system off the mid-atlantic coast. Wednesday will feature more in the way of cloudiness and rain chances as southwesterly flow aids moisture transport across the region ahead of the approaching frontal boundary. Greatest rain chances currently appear likely extending from the nature coast south to central interior and southwest coastal sections. As the mid-atlantic system deepens and lifts northeast Thursday, high pressure building across the ohio valley in its wake will force the frontal boundary south thru the remainder of the peninsula allowing somewhat cooler and drier air to begin filtering into the region under northerly flow. It appears Friday will be relatively close to average, temperature- wise, with increasing cloud cover as northerly surface flow gradually transitions to easterly while southwest flow aloft strengthens out ahead of a shortwave progressing east across the northern gulf coast. A weak surface trough area of low pressure is expected to develop over the southwest gulf Friday into Saturday in response to the shortwave energy and ride northeast toward the central gulf coast and fl panhandle throughout the day Saturday, shifting winds across the peninsula to south southeast as moisture again increases across the region and lingers through the weekend along with the return of above normal temps. Ridging aloft builds across the region and into the western atlantic early next week... With the surface ridge displaced a bit further out in |
the atlantic, allowing continued south southeast flow across the state until another front approaches heading into mid-week. Aviation Vfr conditions expected thru period with variable light easterly flow increasing to southeast 6 to 8 knots by 15z, shifting southwest by 20-21z, decreasing to light variable at southern interior terminals after 02z. Marine High pressure stretching across the peninsula continues light east southeast winds and slight seas today before shifting increasing to southwest 10 to 15 knots Wednesday ahead of an approaching cold front with showers and storms possible. Flow diminishes slightly and becomes northerly Thursday before gradually shifting to east southeast Friday and increasing Saturday. Seas generally 2 to 3 feet in open waters, light chop bay and inland waters. Fire weather Humidity values expected to remain above critical thresholds throughout the period. High pressure to the east responsible for light east southeast flow will give way to an approaching frontal system and increasing rain chances Wednesday with west southwest flow... Gradually shifting to south southeast during the weekend. Rh values will drop behind the front Thursday and Friday but will recover over the weekend.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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. |
