GMZ800 Synopsis For The Coastal Waters From Bonita Beach To Suwannee River- 251 Pm Edt Sat Aug 24 2019
Synopsis.. Area of low pressure currently over the florida peninsula will result in north to northeast winds through Sunday morning before gradually turning southwesterly as the disturbance pulls away off into the atlantic. Through midweek, this flow setup will allow for a better chance of showers and storms early in the morning and moving inland through the day. No headlines are expected at this time... By later in the work week into the weekend, a broad trough of low pressure in the gulf will increase rain chances across the eastern gulf waters.

(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus62 ktbw 241832 afdtbw area forecast discussion national weather service tampa bay ruskin fl 232 pm edt Sat aug 24 2019 Short term Easterly flow is in place as surface low pressure sits over the southern portion of the florida peninsula. This feature is associated with shower and thunderstorm activity currently underway off the east coast of florida, and will act to provide some additional enhancement to showers and thunderstorms primarily from tampa bay southward. While the feature is expected to move out over the atlantic and intensify into a tropical or subtropical storm sometime in the next few days, impacts in the short term for west central and southwest florida will be limited only to the aforementioned enhancement to showers and thunderstorms across the region. Overall a typical summertime pattern associated with easterly flow is expected to hold through the remainder of the weekend with scattered showers and thunderstorms forming in the afternoon hours and highs in the upper 80s at the coast and lower 90s inland. Long term The influence of the tropical disturbance will begin to wane by Monday as a shortwave trough axis begins to usher the system out into the open atlantic ocean. As it does so, a wsw flow will return to the region, leading to wet conditions once more across west central and southwest florida beginning on Tuesday. Showers and thunderstorms will form off the coast in the morning hours and then spread inland throughout the day. This wsw flow will not last, however, as the bermuda-azores high begins to build back in on Thursday at the surface. The anticyclonic (clockwise) movement of air around the feature at the surface will cause winds to become more ese by late in the work weak. This ese flow will continue to keep the pattern wet, particularly in southwest florida as a deep plume of moisture from the caribbean will be advected over the peninsula. Aviation Generally light north to northeast winds early this afternoon. Winds will increase later this afternoon to 7-10 knots and shift |
from the northeast to a more northerly direction and then north- northwest near coastal sites. Vcsh across southern terminals with occasional MVFR CIGS near fmy rsw. Vcts remains in tafs to start by 20z. However, the greatest chance coverage for TS will be southern terminals, where prevailing MVFR CIGS will continue, especially near convection. The region should clear by 01-02 utc. Marine Generally isolated showers and thunderstorms are possible this afternoon evening. Ene winds at 10-12kts will lead to 1-2ft seas across coastal waters, with higher winds and seas possible with passing storms. A similar trend is expected during the day tomorrow as well, but with a slightly higher rain chance in the evening and overnight hours. Winds begin to become more variable and rain chances begin to increase in nearshore waters on Monday as the winds begin to shift back to a wsw flow pattern. From Tuesday through the mid-week time frame, this pattern will lead to high rain chances across coastal waters in the morning hours gradually diminishing throughout the day. Winds are expected to be 10-12kts and seas will be 1-2 feet. Fire weather While slightly drier than last week, ample moisture is present to support afternoon showers and thunderstorms. A wet pattern begins to return by next week, and this will help to keep fire danger low for the next seven days.

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. |
