Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
914 PM EDT Thu Jun 20 2024

.SYNOPSIS...

Weak low pressure situated about 300 miles to the east-southeast
of Mayport, Florida late on Thursday evening may organize into a
Tropical Depression overnight or early on Friday as it progresses
west-northwestward across the Gulf Stream waters, with this
feature approaching the northeast Florida coast late on Friday
morning or during the early afternoon hours. Bands of gusty
showers and embedded thunderstorms will increase in frequency and
intensity during the overnight and predawn hours on Friday, with
this activity continuing through late Friday afternoon before
diminishing in coverage as this weak low pressure center
progresses inland. Meanwhile, strong high pressure centered north
of Bermuda will gradually weaken as it settles southward this
weekend. Small Craft Advisory conditions will continue throughout
our local waters tonight and Friday, followed by winds and seas
diminishing to Caution levels on Friday night and then below
Caution criteria on Saturday. Rounds of showers and thunderstorms
will continue to develop over our local waters this weekend and
into next week as prevailing winds become southerly ahead of a
weakening surface trough that will settle over the southeastern
states through midweek.
