GMZ005 Synopsis For Keys Coastal Waters From Ocean Reef To Dry Tortugas 1033 Am Edt Sat Jun 22 2024

Synopsis - The interaction between low pressure off the east coast of florida, high pressure centered north of bermuda, and broad low pressure in the vicinity of the yucatan peninsula will result in gentle to moderate east to southeast breezes over the next few days. Moisture pulled into our area via the low to the west will result in periods of unsettled weather through this weekend. High pressure building over the north atlantic early next week will result in light to gentle southeast to south breezes and a return to near-normal rain and Thunder chances.

New DISCUSSION, MARINE, AVIATION

DISCUSSION
Issued at 1044 AM EDT Sat Jun 22 2024

Radar has become more active over the last few hours here in the Florida Keys CWA Although showers are plentiful, thunderstorms have been struggling to perform due to warmer temperatures deeper into the atmosphere. 12Z KEY RAOB also reveals while our lower level winds are southeasterly, winds aloft are in the southwestern direction which doesn't help the struggling cloud tops. Wind speeds are 10 to 15 knots across the Reef outside of any convection. Temperatures will struggle to reach the upper 80s with today's cloud coverage and with ample amounts of moisture and CAPE, we could see an active radar for the rest of the day.
Confidence on exact location is hard to nail down, therefore 50% PoPs are appropriate for the remainder of today and tonight. No changes to the forecast are necessary at this time.

MARINE
Issued at 1044 AM EDT Sat Jun 22 2024

There are no watches, warnings, or advisories currently in effect for the Florida Keys coastal waters. From synopsis, the interaction between low pressure off the east coast of Florida, high pressure centered north of Bermuda, and broad low pressure in the vicinity of the Yucatan Peninsula will result in gentle to moderate east to southeast breezes over the next few days.
Moisture pulled into our area via the low to the west will result in periods of unsettled weather through this weekend. High pressure building over the North Atlantic early next week will result in light to gentle southeast to south breezes and a return to near-normal rain and thunder chances.

AVIATION
(15Z TAFS)
Issued at 1044 AM EDT Sat Jun 22 2024

VFR conditions will prevail at both island terminals through the TAF period. While above normal rain chances are expected, timing and coverage will remain difficult to forecast, so have included just VCSH throughout the TAF period for now. Short-term amendments will be issued as needed, based mainly on radar trends.
Outside of any shower or thunderstorm, surface winds will remain from the east to southeast at 6 to 10 knots.

CLIMATE

On this day in 1990, a record rainfall of 4.30" was measured in Marathon. This is also the wettest day ever recorded in the Marathon area for the month of June. Rainfall records for Marathon date back to 1950.
