Marine Weather and Tides
Big Pine Key, 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.

Discussion
Currently
Weak shower coverage has gradually across the western florida
straits, and a few isolated cells have propagated across the
middle and upper keys this afternoon, but only a few lightning
strikes have occurred in our far western forecast domain thus far
today. IR differential water vapor mimic imagery indicates a
steady moistening air mass out of the southwest, near a surface
low just east of the yucatan peninsula that continues to become
better defined. The 2pm special tropical weather outlook from the
nhc has indicated a high chance of tropical or subtropical
development through 48 hours (80%), as well as through 5 days
(90%).

Temperatures across the island chain range from 81 in cloud cover to
87 in peaks of sun, with dew points holding steady near the mid
70s. Across our marine district, winds are east at 10-15 knots.

Forecast
A wet pattern remains in place across the florida keys and most of
the state and southeast us as all eyes remain on the disturbance
east of the yucatan. The system is forecast to remain somewhat
stationary before shifting northward Friday night, emerging into
the southern gulf of mexico Saturday, shifting into the north-
central gulf Sunday into Monday. Primary impacts from the system
for the keys, regardless of development, will be the potential
for heavy rainfall and gusty winds (with isolated thunderstorms)
into memorial day weekend, Saturday and Saturday night under the
greatest probability due to the proximity of the low during that
time frame. Wpc includes portions of the keys in a marginal
excessive rainfall risk for Friday and Saturday.

The tropical or subtropical system is expected to move into the
northern gulf coast Monday evening and into the southeast us
thereafter. However, the bermuda high positioned to our east will
keep deep tropical moisture across the florida keys through at
least Tuesday. However, the high pressure ridge axis shifts
westward, and will drag a dry air mass to south florida mid to
late next week... Possibly putting an end to our highly anomalous
synoptically wet pattern, just in time for the official start of
hurricane season.

Marine
No watches, warnings, or advisories are currently in place across
the coastal waters surrounding the florida keys. Small craft
advisory conditions may be possible Friday night, lasting into the
holiday weekend.

Aviation
Vfr conditions are expected at both the key west and marathon
terminals through this evening and overnight. There is a chance of a
passing shower which may bring brief periods of MVFR conditions.

Near surface winds will be mainly from the east between 5 and 10
knots, increasing to near 15 knots after sunrise Friday.

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.
