AMZ400 Synopsis For Altamaha Sound Ga To Flagler Beach Fl Out To 60 Nm- 233 Pm Est Thu Nov 14 2019
Synopsis.. A coastal trough over the waters will continue to produce moderate winds and hazardous seas for small craft through rest of today. This trough will move onshore and lift slowly northward over the georgia waters tonight as weak low pressure develops over the southeast gulf of mexico. A low pressure center will lift northeastward across north florida on Friday morning, entering the northeast florida waters Friday afternoon. Low pressure will then become stationary over the gulf stream waters off the georgia coast this weekend as it strengthens, bringing strong northerly winds and building seas to our waters.
Gulf stream.. The approximate location of the west wall of the gulf stream as of nov 14, 2019 at 1200 utc... 53 nautical miles east northeast of flagler beach. 48 nautical miles east of saint augustine beach. 53 nautical miles east of jacksonville beach. 71 nautical miles east southeast of st simons island.

Locally heavy rainfall overnight...

Update
Rain was spreading across the region early this evening along and
north of a warm front draped from near st. Augustine southwestward
to marion county and into the gulf of mexico. An area of low
pressure was across the eastern gulf, and this low will move
across northern florida before daybreak on Friday. Strong
isentropic lift, convergence from the area of low pressure and
divergence aloft from an approaching upper trough will lead to
periods of moderate to heavy rainfall overnight into Friday
morning. Rainfall amounts of 2-3 inches with locally higher
amounts through Friday evening are expected along the i-10
corridor northward into southeast georgia to near alma, 1.5-2
inches north of alma, and 0.25-1 inch south of a line from st.

Augustine to gainesville.

Aviation
[through 00z Saturday]
ifr to lifr CIGS will prevail through the period. Rain was moving
along and north of a frontal boundary draped across the area, and
this will impact all the TAF sites overnight. Heavy rain is
possible at the TAF sites overnight through Friday morning. An
area of low pressure will move across the area before daybreak,
and winds will shift to the northwest behind the low Friday
morning. Rain will end from west to east during the afternoon
hours, but drizzle and low clouds will remain ahead of another
upper trough.

Prev discussion [400 pm est]
Near term [through tonight]
Showers, along with a chance for isolated thunderstorms, will be
crossing the region from out of the west bringing rainfall this
afternoon, tonight, and into tomorrow morning along with very low
cloud ceiling heights. There remains some potential for minor
flooding along inland rivers for coastal southeast florida
throughout the evening, in correspondence with higher tides and
onshore winds. Heaviest rainfall amounts for tonight are expected
to occur over southeast georgia and areas west of the i-75
corridor. Overnight low temperatures are expected to be in the
upper 40s and lower 50s for southeast georgia and in the 50s and
lower 60s for northeast florida.

Short term [Friday through Saturday night]
Showers along with a potential slight chance for thunderstorms
will carry over on into Saturday as the upper level low continues
its trek across the southeastern us. Anticipated rainfall amounts
through the weekend are expected to range from 0.5" to 1.0" for
most counties south of i-10 and between 1" to 1.5" for areas
north of there, with some localized rainfall amounts reaching up
to 2" or higher. Wind speeds from out of the north will increase
as the pressure gradient over the region tightens on Saturday and
Sunday, with the strongest winds occuring along the shoreline and
over the waters. Wind gusts of up to 25-35 mph will be possible
during this period, along the coast. Conditions will begin to
clear on Sunday as showers move off towards the east.

Temperatures will drop over the course of the weekend, with high
temps being in the mid to upper 50s for southeast georgia and in
the upper 50s and mid to low 60s for northeastern florida, with
the higher temperatures occuring further to the south. Overnight
low temperatures are expected to reach into the upper 30s for
inland southeastern georgia by Sunday and in the mid to lower 40s
for southeastern florida, with min coastal temps ranging between
the mid 40s and lower 50s.

Long term [Sunday through Thursday]
Chance for showers Monday night, but otherwise conditions are
expected to be dry for most of the day. Chance for showers can be
expected to continue on over into Tuesday as a trough aloft moves
from west to east across the region. High pressure will build in
Wednesday, bringing more stable conditions through the rest of the
week. There will be a gradual increase in high temps going into
next week, with temperatures ranging from the upper 50s and lower
60s on Sunday and then reaching into the upper 60s and lower 70s
by midweek. Overnight low temperatures will also experience a mild
warming trend, with temps starting in the upper 30s and lower 40s
and then warming into the mid to lower 40s for inland areas and
in the lower 50s along coastal areas.

Marine
Seas are expected to remain elevated for florida offshore waters
into the late evening and early am hours,remaining at small craft
advisory levels. Predominantly onshore winds will continue through
tomorrow, with winds reaching up to potentially gale force levels
by Friday afternoon for offshore waters as an overhead low
pressure system works to intensify coastal and offshore winds.

Showers with isolated thunderstorms will continue through the
afternoon and evening, into Friday morning.

Rip currents: a high risk of rip currents today due to strong
onshore winds and rough surf. Moderate risk on Friday as winds
become offshore.
